Advanced energy storage has been a key enabling technology for the portable electronics explosion. The lithium and Ni-MeH battery technologies are less than 40 years old and have taken over the electronics industry and are on the same track for the transportation industry and the utility grid. In this review, energy storage from the gigawatt pumped hydro systems to the smallest watt-hour battery are discussed, and the future directions predicted. If renewable energy, or even lower cost energy, is to become prevalent energy storage is a critical component in reducing peak power demands and the intermittent nature of solar and wind power. An electric economy will demand more electrification of the transportation sector and it is likely that all vehicles sold by the end of this decade will have some level of hybridization. Energy storage capabilities in conjunction with the smart grid are expected to see a massive leap forward over the next 25 years. © 2012 IEEE.

There is a growing demand for energy storage, for intermittent renewable energy such as solar and wind power, for transportation, and for the myriad portable electronic devices. The presence of carbon leads creates a reducing atmosphere, preventing the oxidation of the ferrous formed to ferric. The transient change of lattice constant during the two-phase reaction is clearly observed by the time-resolved X-ray diffraction measurement. Once the lithium is disordered, then the reaction will proceed by a single phase so long as the ordering time is longer than the reaction time. The wider the single-phase regions, the narrower is the miscibility gap and the smaller is the lattice mismatch between the lithium-rich and lithium-poor materials. In addition, once the lithium disorder is generated, then if the time it takes to order is greater than the reaction time, phase separation will not occur and the system will stay disordered throughout the reaction.

Purpose: The purpose of this article is to outline notable alterations occurring in the adolescent brain, and to consider potential ramifications of these developmental transformations for public policy and programs involving adolescents. Methods: Developmental changes in the adolescent brain obtained from human imaging work are reviewed, along with results of basic science studies. Results: Adolescent brain transformations include both progressive and regressive changes that are regionally specific and serve to refine brain functional connectivity. Along with still-maturing inhibitory control systems that can be overcome under emotional circumstances, the adolescent brain is associated with sometimes elevated activation of reward-relevant brain regions, whereas sensitivity to aversive stimuli may be attenuated. At this time, the developmental shift from greater brain plasticity early in life to the relative stability of the mature brain is still tilted more toward plasticity than seen in adulthood, perhaps providing an opportunity for some experience-influenced sculpting of the adolescent brain. Conclusions: Normal developmental transformations in brain reward/aversive systems, areas critical for inhibitory control, and regions activated by emotional, exciting, and stressful stimuli may promote some normative degree of adolescent risk taking. These findings have a number of potential implications for public policies and programs focused on adolescent health and well-being. © 2013 Society for Adolescent Health and Medicine.

Yams (Dioscorea species) are among the primary agricultural commodities and major staple crop in Africa, India, South East Asia, South America and the Caribbean. However, the crop is laden with serious production problems arising from factors such as anthracnose disease, pests, and declines in soil fertility. This project seeks to revolutionize yam production in developing countries through the development and field-testing of low-cost genotyping/phenotyping biosensors that contain an integrated paper-based biobattery. These proof-of-concept devices will provide self-sustainable, field-tested sensing systems that can be used to detect the presence of disease causing pathogens by smallholder farmers in the developing world. The project will provide international interdisciplinary research training for students and postdoctoral researchers. All project outcomes will be available for use by the scientific community. DNA sequences will be available through GenBank. Information about biosensors will be provided through multiple mechanisms that include peer-reviewed publications as well as organized field-testing by smallholder farmers using standard protocols and handouts.

This project will address some of the fundamental research and constraint issues associated with decreased yam production in developing countries. This project aims to develop and characterize the next generation of low-cost biosensors that can be used to assess differences in virulence and inter- and/or intraspecific genetic diversity in fungal isolates that cause anthracnose diseases in Dioscorea alata and Dioscorea cayanensis, two species of yams. Specific objectives are to (i) conduct molecular and biochemical characterization of healthy and fungal-infected yam varieties to identify DNA markers associated with up to 150-180 field-collected fungal isolates; ii) use markers as the basis for designing a multiplex SNP paper-based bioassay to detect the presence of fungal pathogens; iii) attach biosensor that is powered by a novel microbial-based bio-battery to the back of a smartphone; sensor signals could be read visually or via custom-based applications (apps) to be developed for smartphones; and, iv) develop standardized protocols for screening yams for anthracnose resistance using the new biosensing tools as a first step to deploying the technology in the field. It is anticipated that the proposed devices can serve as a model for transforming low-cost tools into precision agriculture to promote increased food production in developing countries in developing countries. In addition, the project can potentially shift the paradigm for flexible and stackable paper-based batteries by enabling, through their architecture and design, exceptional electrical characteristics and functionalities.

Recruiting, engaging, and retaining undergraduate students in STEM disciplines, including geoscience and affiliated fields, is a major educational challenge in the nations colleges and universities. As part of Binghamton Universitys Freshman Research Immersion (FRI) program, a team of five science, technology, engineering, and math (STEM) faculty across the geology, biology and environmental studies disciplines are using the multi- disciplinary field of biogeochemistry to engage students early in their college years in research applicable to geoscience careers. Biogeochemistry investigates the interconnection of biological, geological, and chemical processes. Modern and ancient lake and ocean sediments, the atmosphere, watersheds and wetlands provide field sites and samples for the biogeochemistry research. The biogeochemistry research stream consists of a three course sequence: 1) a research methods course during the fall semester, 2) followed by training in analytical techniques during the spring semester that 3) culminates in completion of a research project the following fall. Funding is being provided for some of the FRI students to engage in hands-on, outdoor, field based components of their research projects during the summer between the spring and fall. This approach allows students to develop projects that incorporate and evaluate seasonality components critical to the understanding of many biogeochemical processes. As a part of the outreach program, high school educators and several of their students participate in a summer workshop where they learn about FRI opportunities through direct interaction with the FRI students, faculty and staff. In turn, the FRI students and their achievements are being used to develop an outreach program that includes visits to high schools and community colleges. Consequently, this program is working to increase the numbers and diversity of students trained in Geosciences, thus meeting a crucial national need within a STEM discipline.

The Freshman Research Immersion (FRI) program is supporting a cohort of 25-30 Biogeochemistry students each year. The biogeochemistry experience begins with a research methods course that emphasizes quantitative reasoning, scientific communication and a semester-long literature review to identify research topics in biogeochemistry. The first half of the spring semester, students learn analytical techniques applicable to biogeochemistry research; by the second half of the spring, they begin their research project. In the fall of sophomore year, students have an entire second semester to continue working on their research project. The biogeochemistry stream has a dedicated laboratory equipped for research, and a PhD-trained research educator who oversees the students, graduate teaching assistant and undergraduate peer mentors. The FRI program features a combination of the multiple components. A team of faculty members with well-established research programs designs and oversees the freshman research themes. The research themes explicitly address core concepts and core skills of the geosciences. The participating freshmen develop electronic-portfolios documenting their research experiences and understanding of the process of science, which they build upon throughout their college years. Students take a sequence of courses that emphasize teamwork, thus provides explicit training to undergraduates on how to work in research teams. The students are exposed to interdisciplinary research (IDR) and engage in multiple opportunities to develop IDR skills. The biogeochemistry research projects generate spin-off research modules that are being infused into other courses; as a result, authentic research experiences eventually will be provided in regular science courses, contributing to improved engagement, learning and retention in the sciences. The undergraduates research activities are expected to result in students being co-authors of presentations and peer-reviewed articles. Assessment activities are documenting the impacts of the stepped, multi-mentored research experience of the FRI program for undergraduates considering a career in geosciences.

The project focuses on advancing the field of digital image steganography -- a covert way of communication in which information is hidden in other objects, such as digital media files, to assure privacy. For a secure steganographic system, it should be impossible to prove the presence of hidden data. Achieving this level of security in practice is extraordinarily difficult because digital media is hard to describe using statistical models with accuracy necessary to guarantee perfect security.

This project works with devices that acquire an image to learn a sufficiently accurate model within which it becomes possible to construct steganography with a verifiable level of security and performance that can be contrasted with theoretically achievable limits. The result is a novel advanced privacy tool needed in countries that prohibit the use of encryption or in a hostile environment when there is need to communicate without attracting attention via channels in control of an adversary or via public, insecure channels. On the other hand, a deeper understanding of the limits of covert communication will facilitate better defense against such methods of deception, an effort recognized as steganalysis. The project explores commercial applications of data hiding include signal authentication, integrity verification, and secure data dissemination. This research contributes to trusted information exchange, data mining, information assurance, network and computer security, counter-deception, and intrusion detection and its prevention.

Proposal Title: A New Approach to Capacitive Sensing: Repulsive Sensors

Brief Description of Project Goals: This research aims to devise a new approach to capacitive sensing and to demonstrate its effectiveness in MEMS microphones.


Hearing aids are useful tools an aging population can use to improve their quality of life. Miniature microphones are a key component in hearing aids and their acoustic performance determines the effectiveness of hearing aids in helping the hearing impaired communicate in noisy environments. Micro-Electro-Mechanical Systems (MEMS) microphones have grown to dominate the market for miniature microphones in portable electronic devices such as cell phones due to their small form factor as well as their compatibility with high-volume manufacturing processes. While MEMS microphones have the potential of providing significant performance improvements in hearing aids, they have generally not yet demonstrated sufficient performance for this demanding application. A goal of the proposed research is to take better advantage of MEMS technology to enable a revolutionary change in the design of high-performance MEMS microphones. If successful, this research will lead to more sensitive MEMS microphones for hearing aids and will have a tremendous impact on the lives of hearing impaired. Noise performance of the MEMS microphone will be the major improvement that can help the aging population hear better.

Capacitive sensing using electrostatic repulsive fingers is a novel concept that can transform many applications suffering from limited functionality due to the pull-in instability of conventional parallel plate sensors. Since the invention of capacitive microphones in 1916, the limitation of pull-in voltage has significantly diminished the functionality of these devices in terms of noise performance and sensitivity. We propose using a Micro-Electro-Mechanical Systems (MEMS) capacitive sensing mechanism based on the repulsive force that, unlike conventional capacitive sensors, does not suffer from pull-in voltage. This approach allows significantly increased bias voltages that will substantially improve the signal-to-noise ratio and electrical sensitivity of microphones. The MEMS microphone examined here is composed of a silicon diaphragm that rotates about an axis upon exposure to sound pressure. The diaphragm incorporates a number of capacitive sensor unit cells, and their change in capacitance converts to a voltage in the preamplifier. A unit sensor cell consists of a movable finger above a vertically aligned fixed finger next to an unaligned fixed finger. When potential differences are made in the aligned and unaligned fingers, an asymmetric electric field is created on the movable finger, generating a repulsive force that pushes it away from the substrate. Our preliminary studies show that the initial gap of the unit sensor cell can be designed so the force on the movable finger remains repulsive, which prevents the collapse of the movable fingers on the substrate (pull-in). The asymmetric electric field distribution on the movable finger causes a complicated coupled relationship between the capacitance and mechanical displacement. Therefore, to gain a fundamental understanding of the coupled system behavior, we will create analytical and numerical models of the capacitive MEMS sensor. Using the model simulations, we will design the sensor for desired sensitivity. Using microfabrication techniques, we will build the sensor and characterize its behavior using a Laser Doppler Vibrometer. After integrating the sensor with preamplifier circuitry, we will test the system in an anechoic chamber to verify the sensor improves the performance and sensitivity of microphones.

This Faculty Early Career Development (CAREER) award will enable a novel additive manufacturing methodology for printing thin-films of nanoparticles. In additive manufacturing, objects with complex shapes are built up by depositing materials layer-by-layer. This approach has revolutionized the creation of large three-dimensional prototypes. However, it is not yet feasible to use this technology to print well-ordered layers at fine length scales. The ability to precisely control the position and orientation of the nanoparticles (i.e. the microstructure) within a thin-film is essential since this governs the electrical, mechanical, and optical properties of the film. The next-generation of high-performance devices for use in energy production, health care, and security will require a high-throughput manufacturing methodology that provides fine feature control. This award supports fundamental research on electrospray printing, a process that has the potential to offer precise control over thin-film structure while maintaining high-volume production. With this technique, electric fields are used to control the production of thin functional layers from nanoparticle solutions. This research will contribute to the acceleration of manufacturing innovation in the United States by enabling the creation of high technology jobs in the area of printed functional nanomaterials. Additionally, this effort will train and motivate students of varied levels and backgrounds in additive manufacturing through their engagement in interdisciplinary research and international partnerships.

Establishing the processing-structure-property relationships for thin-films of functional materials produced by electrospray printing will enable the process to become a viable manufacturing method. Key findings include identifying how the excess nanoparticle electric charge imparted by electrospray governs the structure of a printed deposit. This new knowledge will facilitate the creation of a novel printing technique incorporating substrate-level Coulombic intervention to control the microstructure at a scale that is yet to be achieved. Coulombic intervention uses a fringing field created in the vicinity of a target substrate to accurately steer and position the charged particles emitted by electrospray. Experimental studies and simulations will be used to establish a comprehensive framework for electrospray printing. Probabilistic modeling will provide critical insight into the evolution of an electrospray printed deposit that is difficult to obtain experimentally. This model will ultimately be used to design the structure of printed deposits for targeted functionality. The influence of substrate topology and material properties on film structure will also be elucidated to advance the versatility of electrospray printing.

The number of users streaming mobile video over the Internet has increased at an unprecedented rate throughout the past decade. Because video streaming is a mainstay of mobile computing, it is important that the best possible experience is delivered to users. Many mathematical algorithms have been proposed to improve quality in video-streaming-related domains. Typically, the parameters of these algorithms are established based on machine-centric indicators of video quality. Although researchers have attempted to connect these indicators with true user-perceived quality, in practice, there is often a disconnect. This project aims to improve directly-measurable indicators of user satisfaction in mobile video streaming by taking into account both individual user preferences as well as a users tolerance for less than perfect quality in a specific video.

The proposed research will improve user-specific indicators by connecting problems in video streaming with problems in multi-task learning and collaborative filtering. These machine learning strategies are especially effective for prediction when large amounts of data are available. This effectiveness on large-scale learning fits well into this projects proposed context of improving user-facing indications of satisfaction. These indications include video abandonment, video session times, and collected navigation commands. Unlike user-surveys, these metrics can be collected at large scales through automated tooling in the video player. This research will investigate strategies that combine these large scale measurements with predictions from machine learning approaches toward selecting algorithm parameters that produce the most improvement in user-facing quality. This project will explore such parameter selection strategies in the context of improving user-perceived dynamic adaptive streaming quality. It will also explore such strategies to maintain a fixed level of user-facing quality while reducing mobile display power consumption via backlight scaling. Demonstrations of the approaches produced by this project will be featured in courses at the PIs institution and will be used to draw undergraduate interest toward computer science research.

This project will extend and sustain a widely-used data infrastructure for studying human emotion, hosted at the lead investigators university and available to the research community. The first two versions of the dataset (BP4D and BP4D+) contain videos of people reacting to varied emotion-eliciting situations, their self-reported emotion, and expert annotations of their facial expression. Version 1, BP4D (n=41), has been used by over 100 research groups and supported a successful community competition around recognizing emotion. The second version (BP4D+) adds participants (n = 140), thermal imaging, and measures of peripheral physiology. The current project greatly broadens and extends this corpus to produce a new dataset (BP4D++) that enables deep-learning approaches, increases generalizability, and builds research infrastructure and community in computer and behavioral science. The collaborators will (1) increase participant diversity; 2) add videos of pairs of people interacting to the current mix of individual and interviewer-mediated video; 3) increase the number of participants to meet the demands of recent advances in big data approaches to machine learning; and 4) expand the size and scope of annotations in the videos. They will also involve the community through an oversight and coordinating consortium that includes researchers in computer vision, biometrics, robotics, and cognitive and behavioral science. The consortium will be composed of special interest groups that focus on various aspects of the corpus, including groups responsible for completing the needed annotations, generating meta-data, and expanding the database application scope. Having an infrastructure to support emotion recognition research matters because computer systems that interact with people (such as phone assistants or characters in virtual reality environments) will be more useful if they react appropriately to what people are doing, thinking, and feeling.

The team will triple the number of participants in the combined corpora to 540. They will develop a dyadic interaction task and capture data from 100 interacting dyads to support dynamic modeling of interpersonal influence across expressive behavior and physiology, as well as analysis of emotional synchrony. They will increase the density of facial annotations to about 15 million frames in total, allowing the database to become sufficiently large to support deep-learning approaches to multimodal emotion detection. These annotations will be accomplished through a hybrid approach that combines expert coding using the Facial Action Coding System, automated face analysis, and crowdsourcing with expert input from the research community. Finally, the recorded data will be augmented with a wide range of meta-data derived from 2D videos, 3D videos, thermal videos, and physiological signals. To ensure the community is involved in sustaining the infrastructure, in addition to the governance consortium described above, the investigators will involve the community in jointly building both APIs that allow adding meta-data and annotations and tools to support the submission and evaluation of new recognition algorithms, then organizing community-wide competitions using those tools. The research team will also reach out to new research communities around health computing, biometrics, and affective computing to widen the utility of the enhanced infrastructure, grow the community of expert annotators through training workshops, and build an educational community around the infrastructure that facilitates the development and sharing of course materials that use it. Long-term, the infrastructure will be funded through a combination of commercial licensing and support from the lead universitys system administration group.
