Photonic circuits aligned to single NV centers are fabricated in diamond using femtosecond laser writing, to enable an integrated platform for the excitation and collection from these optically active spin defects. Diamond is considered by many to be the perfect material. Apart from its remarkable beauty when suitably cut, it is the hardest naturally occurring bulk material, has a record high thermal conductivity and offers excellent transparency from the ultraviolet to far infrared. However it is another characteristic which has quantum optics scientists excited about diamond. Analogous to semiconductors and conventional electronics, the key to making diamond functional is an impurity: a point defect called the nitrogen-vacancy (NV) center – ‘nature’s single photon source’. The NV center, which is present in both naturally occurring and synthetically fabricated diamond, consists of a nitrogen with a neighboring empty site replacing carbon atoms in the diamond lattice. The optically active defect boasts long room temperature spin coherence time, making them attractive as quantum bits. Unlike classical computers which rely on digital 0s and 1s, quantum bits can be in 0 and 1 states simultaneously, enabling an exponential speed increase for certain calculations. Quantum computers are particularly useful for solving challenging multivariable problems such as nanoscale simulations in modern science or macroscale problems like predicting the world climate or fluctuations in the stock market. In addition, due to the magnetically sensitive ground state of NV centers, they can be used to measure weak magnetic fields with nanoscale resolution, which has triggered significant research into diamond-based optical magnetometers. An integrated optics platform in diamond would be beneficial for magnetometry due to the enhanced interaction provided by waveguides, and quantum computing, in which NV centers could be optically linked together for long-range quantum entanglement, due to stability and integration provided by monolithic waveguides. However, it remains a challenge to fabricate optical waveguides in diamond, particularly in 3D architectures, due to its hardness and chemical inertness. In an international collaboration between University of Calgary, Politecnico di Milano and the Institute for Photonics and Nanotechnologies (IFN) – CNR, we recently demonstrated the fabrication of 3D optical waveguides in bulk diamond using focused ultrashort laser pulses in a laboratory at CNST-IIT Milano (Figure 1). As confirmed by optically detected magnetic resonance, mRaman spectroscopy and photoluminescence measurements, we showed that the high repetition rate laser writing produced a waveguide with preserved crystallinity. Crucially, we found that the remarkable properties of the NV centers (Figure 2) were maintained, allowing photons to be efficiently carried between the defects, a crucial step in building a scalable quantum photonic platform. Figure 2. Inset shows cross sectional microscope image of buried diamond waveguide, with the optical mode guided between two laser written modification tracks separated by 13 mm. The photoluminescence spectrum inside the waveguide is the same as the pristine diamond, demonstrating preserved nitrogen vacancy properties, crucial for applications in quantum computing and magnetometry. The concentration of NV centers depends on the purity of the diamond, however the defects are randomly distributed throughout the volume. It is highly desirable to deterministically produce NVs on demand with submicron resolution, prealigned with existing photonic circuits. Recently, Chen et al. demonstrated that femtosecond laser static exposures produced vacancies in the bulk of diamond. After annealing at 1000°C, the laser formed vacancies diffused toward nitrogen impurities to produce on-demand and high quality single NVs . We have taken these pioneering works of laser fabrication of optical waveguides[3, 5] and NVs a step further, by incorporating these important building blocks on the same integrated diamond chip, to enable the robust excitation and collection of light at NVs. Because a single laser microfabrication system is used, the alignment between NVs and waveguides is achieved with submicron resolution. Using confocal photoluminescence microscopy and wide-field EMCCD imaging, we demonstrated the coupling of single NVs using optical waveguides (Figure 3). Optically addressed NV centers could open the door for more sophisticated quantum photonic networks in diamond. For example, in quantum grade diamond, the optically linked single NVs could be exploited for single photon sources or solid state qubits. In lower purity diamond, the laser writing of high density NV ensembles within waveguides could enable robust excitation and collection of the fluorescence signal for magnetometry. Figure 3.

Scientists have gotten better at predicting where earthquakes will occur, but they're still in the dark about when they will strike and how devastating they will be. In the search for clues that will help them better understand earthquakes, scientists at the University of Pennsylvania are studying a phenomenon called ageing. In ageing, the longer that materials are in contact with each other, the more force is required to move them. This resistance is called static friction. The longer something, such as a fault, is sitting still, the more static friction builds up and the stronger the fault gets. Even when the fault remains still, tectonic motion is still occurring; stress builds up in the fault as the plates shift until finally they shift so much that they exceed the static friction force and begin to slide. Because the fault grew stronger with time, the stress can build up to large levels, and a huge amount of energy is then released in the form of a powerful quake. "This ageing mechanism is critical in underlying the unstable behavior of faults that lead to earthquakes," said Robert Carpick, the John Henry Towne Professor and chair of the Department of Mechanical Engineering and Applied Mechanics in Penn's School of Engineering and Applied Science. "If you didn't have ageing, then the fault would move very easily and so you'd get much smaller earthquakes happening more frequently, or maybe even just smooth motion. Ageing leads to the occurrence of infrequent, large earthquakes that can be devastating." Scientists have been studying the movement of faults and ageing in geological materials at the macroscale for decades, producing phenomenological theories and models to describe their experimental results. But there's a problem when it comes to these models. "The models are not fundamental, not physically based, which means we cannot derive those models from basic physics," said Kaiwen Tian, a graduate student in Penn's School of Arts & Sciences. But a Penn-based project seeks to understand the friction of rocks from a more physical point of view at the nanoscale. In their most recent paper, published in Physical Review Letters, the researchers verified the first fundamental theory to describe ageing and explain what happens when load increases. The research was led by Tian and Carpick. David Goldsby, an associate professor in the Department of Earth and Environmental Science at Penn; Izabela Szlufarska, a professor of materials science and engineering at the University of Wisconsin-Madison; UW alumnus Yun Liu; and Nitya Gosvami, now an assistant professor in the Department of Applied Mechanics at IIT Delhi, also contributed to the study. Previous work from the group found that static friction is logarithmic with time. That means that if materials are in contact for 10 times longer, then the friction force required to move them doubles. While scientists had seen this behavior of rocks and geological materials at the macroscopic scale, these researchers observed it at the nanoscale. In this new study, the researchers varied the amount of normal force on the materials to find out how load affects the ageing behavior. "That's a very important question because load may have two effects," Tian said. "If you increase load, you will increase contact area. It may also affect the local pressure." To study this, the researchers used an atomic force microscope to investigate bonding strength where two surfaces meet. They used silicon oxide because it is a primary component of many rock materials. Using the small nanoscale tip of the AFM ensures that the interface is composed of a single contact point, making it easier to estimate the stresses and contact area. They brought a nanoscale tip made from silicon oxide into contact with a silicon oxide sample and held it there. After enough time passed, they slid the tip and measured the force required to initiate sliding. Carpick said this is analogous to putting a block on the floor, letting it sit for a while, and then pushing it and measuring how much force it takes for the block to start moving. They observed what happened when they pushed harder in the normal direction, increasing the load. They found that they doubled the normal force, and then the friction force required also doubled. Explaining it required looking very carefully the mechanism leading to this increase in friction force. "The key," Carpick said, "is we showed in our results how the dependence of the friction force on the holding time and the dependence of the friction force on the load combine. This was consistent with a model that assumes that the friction force is going up because we're getting chemical bonds forming at the interface, so the number of those bonds increase with time. And, when we push harder, what we're doing is increasing the area of contact between the tip and the sample, causing friction to go up with normal force." Prior to this research, it had been suggested that pushing harder might also cause those bonds to form more easily. The researchers found that this wasn't the case: to a good approximation, increasing the normal force simply increases the amount of contact and the number of sites where atoms can react. Currently, the group is looking at what happens when the tip sits on the sample for very short amounts of time. Previously they had been looking at hold times from one-tenth of a second to as much as 100 seconds. But now they're looking at timescales even shorter than one-tenth of a second. By looking at very short timescales, they can gain insights into the details of the energetics of the chemical bonds to see if some bonds can form easily and if others take longer to form. Studying bonds that form easily is important because those are the first bonds to form and might provide insight into what happens at the very beginning of the contact. In addition to providing a better understanding of earthquakes, this work could lead to more efficient nano-devices. Because many micro- and nano-devices are made from silicon, understanding friction is key to getting those devices to function more smoothly. But, most important, the researchers hope that somewhere down the line, a better understanding of ageing will enable them to predict when earthquakes will occur. "Earthquake locations can be predicted fairly well," Carpick said, "but when an earthquake is going to happen is very difficult to predict, and this is largely because there's a lack of physical understanding of the frictional mechanisms behind the earthquakes. We have long way to go to connect this work to earthquakes. However, this work gives us more fundamental insights into the mechanism behind this ageing and, in the long term, we think these kinds of insights could help us predict earthquakes and other frictional phenomena better." This research was supported by a grant from the Earth Sciences Division of the National Science Foundation.

Many think the development of technology is reserved only for the super-intelligent, and that the average person cannot comprehend it. This particular view of technology is a product of a closed-type environment, which hides key information related to the development of technology behind patents, copyrights and trademarks. While it’s debatable how intellectual property rights of inventors must be saved from abuse, traditional modes of doing so can block the flow of information in society. This model is primarily driven by commercial interests— where key technological inventions sell at very high prices. But this model increases the divide between the ‘privileged’ class and the ‘under-privileged’ class. The division of the world between developed, developing and under-developed nations is primarily based on the level of technology they possess. This leads to prohibitively expensive technology and an increasing technological divide— we are producing a generation of technology users instead of technology developers. Open source technologies are changing this picture. The term ‘open source’ refers to technology with a publicly accessible design that can be modified as desired without any restriction. This concept was initially created in the software field—when source codes were made publicly available with a license in which the copyright holder provides the rights to study, change, and distribute the software—but it has since expanded to other industries. The open source movement is now enabling the under-privileged class to work with tools that previously only the privileged class could access. This gives everyone equal footing on development platforms. Products can now be chosen on their merit rather than because they are the only option. If we tread the path of open source diligently, the coming century has a lot of promise. The R&D community has a particularly important role to play in this arena. We have the opportunity to change the very idea of technology as it is perceived by the average person. First, we must mix education and research to a level that they do not distinguish themselves separately. This cannot be done by commercial products, as that will cause the already expensive education system to become even more expensive. Second, we must infuse open source products into education and accompanying research, so that we can make a society of developers instead of users. Third, we must infuse open source tools into research, so that the results can be experimented and verified by a large number of people. Research institutions provide most of the man-power for technology-based industries. If we train them in open source usage, the acceptability of open source solutions in industry will also increase. This domino effect will ultimately benefit both industry (reduced cost of development) and customers (can customize their product). Linux—a computer operating system assembled under the model of free and open-source software development and distribution— has been one of the biggest contributors to open source. Within the scientific community it enabled students, educators and researchers to utilize their computers to any extent they wish. It’s not surprising that most of the tools on Linux were developed by educators and students. Its importance can be judged by the fact that it is now used to run much of the internet, both in terms of hardwar and, software. Numerous derivatives sprouted from Linux as well. Research labs are increasingly shifting their workload to Linux-based systems because they can now freely customize the computing environments to their needs. Open source programming languages like python, R, and Julia have been successful because developers can customize to meet the needs of the community quickly. What Linux did for software, Arduino and Raspberry Pi did for hardware. They enabled students, educators and researchers to easily prototype their circuits and share with the community. Like Linux, many derivatives and even new configurations sprouted from the idea of providing users an open source hardware platform. This enabled mass usage, which in turn lowered the prices. Schools, universities and research labs now use open source boards widely, since they enable a rich teaching-learning paradigm involving learning-by-doing. The internet has connected the development community and they can now share their codes, plans and execution strategies. The number of developers from developing and under-developed countries has been growing as a result. Taking a cue from open source software and hardware, educators have open sourced their content as well. Numerous efforts to provide quality open source textbooks, video lectures and supplementary material has enabled students from under-privileged backgrounds to learn from state-of-the-art content. The Massachusetts Institute of Technology (MIT) was one of the first to do this when they open sourced their teaching content as MIT Open Course Ware (OCW). Now leading websites like Coursera and edX provide educational content from thousands of universities around the world. Educators are benefiting from this movement too. They can now learn how to better teach the content in the best possible manner. Apart from just using open source projects, one university did something more. IIT-Bombay, in India, leads the effort to create a vibrant community of open source developers running the Free and Open Source Software for Education (FOSSEE) project. A textbook companion project has provided codes for hundreds of textbooks, which in turn, can be used by educators in their classroom. A cost effective 10-inch laptop which comes pre-installed with open source tools has been a star attraction for less fortunate sections of society. Spoken tutorials have helped train students, educators and researchers in mass numbers in open source technologies. Numerous other products like eSIM (for designing and simulating electronic circuits), OpenModelica (open source equivalent of Modelica), Sandhi (open source equivalent of LabVIEW) and OpenPLC are just a few open source technologies that are available. Scientific journals have also embraced open source models. Most leading publishers give an option to make the articles and supplementary material open sourced (free to download and distribute without restrictions). This enables wider visibility, which in-turn increases the number of citations. Since citations have been the primary mode to evaluate a researcher, this option is gaining popularity. The open source model is not anti-profit. Numerous companies including Red Hat, Ubuntu and Google prove that one can provide quality open source products and still make money by selling accompanying services. In fact, many companies are now shifting to an open source model for the development of their product, as it is a cost-effective and quick option. Even if components of a product are open sourced, it can still be patented if it is unique in nature of application of the patent. Most often, open sourced products make money via selling services and training. Open source products eventually become more reliable and secure than commercial counterparts because of the sheer number of volunteers who test and rectify bugs. But open source is more than software and hardware. It’s an idea. And like any other idea, it is viral. It’s about being global. It’s about infusing democracy within the scientific community. It’s enabling users to become developers. It’s increasing the number of innovations and reducing the time to commercialize And it’s letting us revisit our society’s roots—as one that encourages the free flow of information and growth in a sustainable manner. Dr. Sandeep Nagar is Assistant Professor at GD Goenka University in India. He obtained a Ph.D in material science from KTH Royal Institute of Technology in Sweden. In his academic career, he actively uses open-source tool chain for teaching and research efforts. He has authored four books on python, octave, SCILAB and MATLAB for learning these tools and comparing them before making a judgment of their usage. His research interest includes IoT, automation, smart grid and nanotechnology based products for green energy.

Ketchup’s sluggish pace as it oozes out of its bottle is a longstanding nuisance — but one that is about to be upended by a new product coming to market. The brainchild of MIT mechanical engineer Kripa Varanasi and his students, a new coating called LiquiGlide is set to make the transition from the laboratory to consumer and industrial markets. LiquiGlide renders a surface highly slippery and allows every last drop of ketchup — or almost any other viscous product, from paint, to glue, to cosmetics — to flow from its container without sticking, saving billions of gallons of product from going waste. “Viscous products sticking to the inside of containers leads to huge losses across industries,” Varanasi says. “For example, in paint manufacturing alone, paint sticking to the inside of mixing and holding tanks costs the industry more than 100 million gallons of lost product and billions of dollars per year in associated waste costs. Using the LiquiGlide platform, we are on a mission to eliminate waste generated across manufacturing applications, in areas ranging from food and agrochemical production to health care and energy, to usher in a new era of sustainable manufacturing.” LiquiGlide, which emerged from research initially funded by an MIT Energy Initiative seed grant and an Innovation grant from the Deshpande Center, is just one in a long line of startling discoveries to emerge from Varanasi’s lab. Most of them involve ways of modifying interfaces. “Interfaces are ubiquitous and a lot of important phenomena occur at them, be it mass, momentum, energy, or charge transfer,” he says. “When I came to MIT in 2009 as a faculty member, my vision was to fundamentally alter interfaces to dramatically improve performance across various industries including energy, water, agriculture, manufacturing, food, and medicine. This required both a deep scientific endeavor to change the paradigm and simultaneous effort in scale-up and manufacturing to translate the technologies to market.” The findings by Varanasi and his collaborators could not only help consumers get those last drops of ketchup, honey, or skin cream out of their jars, they may also enhance many other processes relating to manufacturing and power plants, airplane de-icing, flow in pipelines, water treatment and desalination, and reducing agricultural runoff, to name just a few of the team’s recent research results. For Varanasi, the first step in tackling these big problems was getting a better understanding of exactly how the processes worked. “First you have to understand the problem and ask the right questions. A mechanistic understanding is crucial. If you don’t understand the crucial bottlenecks and rate-limiting steps, then you’re looking for a needle in a haystack. Most of the times, significantly larger-than-required effort is expended in running processes. My approach is to develop a rigorous thermodynamic framework that helps identify the true bottlenecks and then figure out efficient kinetic pathways to impart the solution. The exciting part of this is we get the opportunity to learn about multiple disciplines and cross-pollinate our learnings.” Part of that understanding involved finding ways to simplify the mathematical descriptions of what was going on. “If you really understand the phenomena, you can reduce it to a few nondimensional parameters,” Varanasi says. That collapses the complexity into manageable formulas and phase diagrams, “and then we can design new processes, new products, and zero-tradeoff solutions.” That approach, he says, has been “at the heart of the companies we’ve started.” Asking the right questions Varanasi’s choice of a career in science and academia was inspired by a long family history. He grew up in Hyderabad, in southern India, where his father works as an electrical engineer and his mother is a physics lecturer. His grandfathers were teachers. “There was a lot of that in the family — my parents were my first teachers and role models,” he says. He credits his mother Kanthi especially for initiating his ambitions in both science and entrepreneurship, and his father Mohan Rao with helping him to understand mathematics and build science projects. While in school, he was active in science fairs, physics and math competitions, and building various projects starting with a kit of electronic circuits. “My mom got me this amazing kit, and my dad would help me understand how to build stuff with it,” he recalls. After high school in his home city, he went on to earn his undergraduate degree from the Indian Institute of Technology in nearby Madras before coming to MIT as a graduate student to earn his masters and doctoral degrees. “IIT Madras taught me the fundamentals in engineering and gave me the confidence to pursue my dreams,” he says. “Coming to MIT was transformational,” he says. Among other things, he says, he learned the importance of “asking the right questions — not just ‘why,’ but then ‘why not?’” It also taught him about “the entrepreneurial spirit and how to apply it to solving real problems.” He then went into industry, taking a job in the research labs at GE, where he worked for about four and a half years before getting a faculty appointment at MIT. He says working at GE helped him understand what it takes to translate an idea into a useful product. In 2015, he earned tenure as an associate professor in the Department of Mechanical Engineering. He met his wife Manasa during a trip home to India after finishing his doctoral work. She came back with him to the U.S. and then pursued a MS specializing in nanoelectronics. They have one son and a daughter. Varanasi says that the original inspiration for LiquiGlide’s application to consumer products came from Manasa’s suggestion that there must be a better way to get honey out of a jar. “She is very much a part and parcel of everything I do here,” he says. In addition to LiquiGlide, Varanasi has launched another startup company, in partnership with MIT professor of chemical engineering and Associate Provost Karen Gleason, called DropWise. The company is developing durable hydrophobic coatings for power plants and other industrial machinery, to boost their overall efficiency. He points out that 85 percent of the world’s electricity generators rely on steam cycles that are mostly powered by fossil fuels, so even a small improvement in their operating efficiency could have a significant impact on global greenhouse gas emissions. “It has been absolutely terrific to be able to work with MIT students, postdocs, and colleagues,” he says. “It is a great pleasure to see the energy and passion that my students and postdocs bring to the table, and I am very thankful for their hard work and efforts — we are like a family solving these important problems and having fun doing so.” “I’m really passionate about entrepreneurship and translating the research findings from my lab to useful products that provide societal benefit and create economic value,” Varanasi says. “Otherwise, the insights from research do not get used; you can create something unique, but then it can get lost. So getting to a proof of product is very important to me — not just a proof of concept.”

RESEARCH TRIANGLE PARK, NC--(Marketwired - February 21, 2017) - Nearly one-third of surveyed pharmaceutical companies look to fair-market value (FMV) budget as one their most important criteria for evaluating investigator initiated trial (IIT) proposals, according to a study by business intelligence firm Cutting Edge Information. The study, Investigator-Initiated Trial Management: Expedite Approval Timelines and Establish Compliant Funding Practices, found that many drug companies channel IIT submissions through a financial or budget department to conduct an FMV evaluation of the investigator's itemized budget. Scrutiny over investigator fair-market value has increased since the Sunshine Act passed in 2009. The US Physician Payment Sunshine Act requires pharmaceutical companies to ensure that any money paid to a physician for a particular task is done so at fair-market value. And if the proposed budget is not FMV-compliant, the investigator must revise the budget or provide ample justification for each offending expenditure. Moreover, if the investigator does not submit a detailed budget for an FMV analysis, the proposal will be rejected. "The first step toward a quality FMV review actually occurs before the investigator submits the IIT proposal," said Natalie DeMasi, research team leader at Cutting Edge Information. "Medical affairs teams need to effectively communicate the need for an itemized budget to be accompanied with each proposal." However, IIT teams should not expect all new proposals to conform to fair-market value. The study revealed that the most common way of responding to IIT proposals is to send budgets back so investigators can make revisions themselves; 83% of surveyed IIT teams take this approach. A third of surveyed teams send an already revised budget back for the investigator to approve, sign and return to the company. Some teams take an even firmer stance with offending budget proposals. The line-item veto approach is used by 43% of teams, and 13% of teams reject proposals outright -- meaning if the proposal does not conform to FMV or is deemed too expensive, investigators are not given a chance for revisions. Investigator-Initiated Trial Management: Expedite Approval Timelines and Establish Compliant Funding Practices by Cutting Edge Information, available at https://www.cuttingedgeinfo.com/product/investigator-initiated-trial-management/, provides performance metrics about IIT evaluation timelines and the number of IIT submissions teams receive, evaluate and approve.
