Namiko Yamamoto, assistant professor of aerospace engineering at Penn State, was recently awarded $447,663 through the Office of Naval Research (ONR) Sea-Based Aviation Airframe Structures and Materials program to study fundamental toughening mechanisms of novel ceramic composites and their use as alternative materials for high-temperature applications in the aerospace industry. Through her project titled "Multi-functional Nano-porous Ceramics," Yamamoto, in collaboration with Jogender Singh, professor in the Department of Materials Science and Engineering and chief scientist in Penn State's Applied Research Laboratory, will seek to understand how the introduction of nano-pores into ceramics contributes to enhanced fracture toughness and increased damage tolerance, with minimal compromising of the material's strength. "Tougher ceramic materials are in high demand for numerous aerospace applications that require adequate mechanical strength, stability in extreme environments and lightweight materials," said Yamamoto. "Although ceramics exist that meet those requirements, their applications as bulk structural materials are currently limited to their brittleness and low fracture toughness." Ceramics have a unique combination of material properties, such as low density, high strength at high temperatures, wear resistance, corrosion resistance and low thermal and electrical conductivities. However, when high stress is placed on them, premature or catastrophic failure can occur. Recently, some unique deformation behaviors have been observed when nano-porous ceramics are indented, including shear banding of collapsed pores. If controlled, this quasi-plastic deformation could potentially contribute to intrinsic toughening of ceramics and effectively mitigate crack initiation and propagation. "Systematic understanding is currently missing about shear banding and its relation to fracture toughness of nano-porous ceramics," said Yamamoto. "By conducting multi-scale parametric studies, we hope to gain the knowledge that is critical to the acceleration of practical fabrication and use of macro-scale, nano-porous ceramic materials with increased damage tolerance. Also, through field-assisted sintering technology, we will pursue scalable manufacturing of such nano-porous ceramics." If successful, the toughened nano-porous ceramics could find use as alternative materials for high-temperature and high-shear loading applications in aerospace engineering parts, helicopter rotor heads, ball-point bearings, gear boxes, thermal and physical protection layers, abrasive cutting tools and more. Funding for the project will span three years and will support ONR's interest in the field of Sea-Based Aviation Airframe Structures and Materials. Yamamoto also received an ONR grant in 2016 for her research proposal titled "1D-Patterned Nanocomposites Structured Using Oscillating Magnetic Fields."

Panama City, FLA., June 09, 2017 (GLOBE NEWSWIRE) -- Lufthansa German Airlines, one of the largest airlines in Europe, has successfully completed emissions testing on a fully synthetic renewable jet fuel. The fuel, trademarked as ReadiJet®, was produced by the Biofuels ISOCONVERSION process jointly developed by Applied Research Associates, Inc. (ARA) and Chevron Lummus Global (CLG). The process converts any renewable fat, oil, or grease into high yields of 100 percent drop-in, pure hydrocarbon fuels. “Lufthansa evaluated several different fuels for its ‘High Biofuel Blends in Aviation’ report and wanted to include ours because it’s unique – it’s unblended,” said ARA Principal Engineer Ed Coppola. “All of the other fuels had to be blended with petroleum. They wanted to determine the effects of a clean fuel that didn’t have a lot of impurities like Sulphur and look at the chemistry on the emissions.” "The HBBA report can be downloaded from www.HBBA.eu. Emissions tests were performed in a CFM56-5C4 engine that is used to power the Airbus A340 aircraft. “This is the largest engine that our fuel has ever been tested on,” said Coppola. “You could stand inside the intake of the engine.” Tests were performed at multiple power settings including ground idle, flight idle, takeoff, and maximum continuous thrust. Even though ReadiJet® contained about five percent more aromatics than the petroleum baseline fuel that was tested for comparison, CO, NOx, and particulate emissions were essentially the same as produced by the petroleum fuel. The results from Lufthansa’s test could be used as part of the American Society for Testing and Materials (ASTM) review process currently underway to certify ReadiJet® for commercial use. This will result in a new specification Annex to ASTM D7566, “Aviation Turbine Fuel Containing Synthesized Hydrocarbons.” The U.S. Navy is also performing certification testing on neat, unblended ReadiJet® and ReadiDiesel® which will result in new military specifications. When the MILSPEC certification is complete, ReadiJet® and ReadiDiesel® will be the ONLY 100 percent renewable fuels certified by the Department of Defense that meet petroleum fuel specifications without blending. ARA delivered more than 150,000 gallons of 100 percent drop-in jet and diesel fuel to the U.S. Navy in 2016 as part of a certification fuel contract. On October 29, 2012, the National Research Council Canada flight-tested ReadiJet® using their Falcon 20 aircraft in the world’s first ever 100 percent drop-in renewable jet fuel flight. The flight demonstrated more than 50 percent reduction in particle emissions while obtaining a 1.5 percent reduction in specific fuel consumption compared to petroleum-derived jet fuel. ReadiJet® gives more miles per gallon than petroleum based fuel and a lot more miles per gallon than other renewable fuels. This means longer range for aircraft flying with ReadiJet®. In addition to being compatible with current turbine and diesel engines, ReadiJet® and ReadiDiesel® do not have to be segregated from their petroleum counterparts. These fuels can utilize existing petroleum infrastructure without the need to build additional, costly infrastructure for blending, transportation, and storage. Applied Research Associates was founded in 1979 and is an employee-owned scientific research and engineering company dedicated to solving critical national problems to improve our safety, security and way of life. ARA has earned significant recognition in National Security, Transportation, Energy & Environment, and Health & Human Safety and has set standards of excellence in service and technology that extend into new territory.

VANCOUVER, BC--(Marketwired - February 24, 2017) - Traditional methods for reforestation use seeds from local tree populations. With the climate quickly changing, these local trees will be poorly adapted to new environments that not only have warmer temperatures, but also more disease pressures. And climate change isn't just bad for trees. It's also bad for the economic and environmental benefits they provide to Canada -- benefits like wood, jobs, habitat protection and carbon sequestration. Foresters have three options for dealing with this problem: reforest with the same species, but with trees that are better adapted to warmer climates; move species further north or to higher elevations; or select and breed trees that can better withstand climatic stresses or disease. All of these strategies can be successful, but only if we have scientific knowledge about which trees can better withstand a changing climate and the stresses that accompany it. Dr. Sally Aitken of the University of British Columbia (UBC) is leading a team, including Sam Yeaman of the University of Calgary and Richard Hamelin of UBC and Université Laval, that will use genomics to test the ability of trees from different populations to resist heat, cold, drought and disease, and identify the genes and genetic variation involved in climate adaptation. The ultimate goal of the project, valued at $5.8 million, is to develop better reforestation strategies for economically important tree species such as Douglas-fir and lodgepole pine, as well as western larch and jack pine. "Better matching trees with new climates will improve the health and productivity of planted forests. To understand the adaptation of trees to both climate and diseases, we will use genomic tools along with climate modeling and seedling experiments," says Dr. Aitken, a Professor in the Faculty of Forestry. "Our previous research has shown these approaches will give us these answers in a few years rather than in a few decades. The success of this research is dependent on our close collaboration with provincial tree breeders and forest managers." "Our ministry is pleased to be a major partner in the CoAdapTree research project, in collaboration with Dr. Aitken's team at UBC," said Forests, Lands and Natural Resource Operations Minister Steve Thomson. "Together, we are developing important tools to implement climate-based seed transfer. The B.C. government is committed to using the results of this research to improve forest management practices that will benefit all British Columbians." The project, CoAdapTree: Healthy trees for future climates, will provide recommendations for climate-based seed transfer policy to guide foresters in planting trees that will be healthy in new climates in western Canada. Climate-based seed transfer can result in up to 30% greater timber yields, with a proportional impact on the economy and employment, and will also sustain ecological and environmental benefits of forests. "The forestry industry contributed more than $20 billion to Canada's GDP in 2014, and directly and indirectly employed 288,000 people," says Dr. Catalina Lopez-Correa, Chief Scientific Officer and Vice President, Sector Development at Genome BC. "We have been investing in forest research since 2001 and have funded an earlier phase of Dr. Aitken's genomics and climate-change research because this industry is critical to BC's economy and this work will make a major difference to future forest outcomes." The project was awarded through Genome Canada's 2015 Large-Scale Applied Research Project Competition Natural Resources and the Environment: Sector Challenges -- Genomic Solutions. Funders of this work include Genome Canada, Genome BC, Genome Alberta, Genome Quebec, BC Ministry of Forests, Lands and Natural Resource Operations, the Forest Genetics Council of BC, and Natural Resources Canada. It is also funded by forest companies including West Fraser, CanFor, and the Sinclair Group, partners in the Vernon Seed Orchard Company, as well as Western Forest Products Inc., and TimberWest Forest Corp.

Given the growing demands placed on the electrical, optical and thermal functionality of LEDs, engineers are paying more and more attention to the advancement of new material properties. To this end, the FLINGO project (Functional Inorganic Layers for Next Generation Optical Devices) was established to develop new materials (layers, in particular) and processes to improve the efficiency and durability of LEDs. As the project coordinator, Osram Opto Semiconductors is working with renowned universities, research institutes and companies to maintain and improve market leadership in innovative LED products. The German Federal Ministry for Education and Research is sponsoring the FLINGO project – set to run through January 2020 – as part of the M-ERA.NET EU initiative, an EU-financed network set up to support the coordination of European research projects. In the FLINGO project, researchers will investigate and combine different deposition methods for thin films such as atomic layer deposition, spray pyrolysis and the sol gel process for manufacturing high-quality LED light sources. Under the leadership of Dr. David O’Brien from Osram Opto Semiconductors, the project partners will be working on the entire bandwidth of new component properties – including extended lifetime, smaller electrical layer resistance and improved light extraction. These require new materials and innovative or adapted deposition processes. “The project objectives can only be achieved with the assistance of a broad-based consortium because they call for improvements, new developments and especially expert know-how across the entire value added chain,” explained O’Brien. Interdisciplinary expertise from five project partners The members of the FLINGO project in addition to Osram Opto Semiconductors are: Uninova from the New University of Lisbon; the Finnish thin film technology company Picosun Oy; the Fraunhofer Institute for Silicate Research ISC in Würzburg; and Vilnius University. Fraunhofer ISC provides support with its proficiency in the development of new inorganic layer systems which are to be used as the matrix for sensitive converter materials. Uninova adds its expertise in the manufacture of highly transparent and highly conductive layers which are needed for the p-contact in the LEDs. Picosun Oy is developing atomic layer deposition (ALD) processes and new materials to ensure conformal coating of even heavily structured surfaces. The Institute for Applied Research at Vilnius University provides specialist knowledge in the development and characterization of non-destructive material properties and will analyze the new layers and layer systems developed in the FLINGO project. As an end user of the technologies developed in FLINGO, Osram Opto Semiconductors will ultimately transfer the new thin layers and layer systems to its LEDs to test them for their suitability for the mass market. “The results of the project should lead to highly efficient and durable white light LEDs with possible applications in general lighting for example,” added O’Brien. “Our intention here is to improve our competitiveness and that of European industry in this field.” ABOUT OSRAM OSRAM, based in Munich, is a globally leading lighting manufacturer with a history dating back about 100 years. The product portfolio includes high-tech applications based on semiconductor technology such as infrared or laser lighting.

When a child suffers a mild head injury, doctors have well-established protocols for determining whether that child should have a computed tomography (CT) scan to assess the damage. Most children with mild traumatic brain injury have normal CT scans—a scenario referred to as a concussion. If a CT scan is abnormal, however, a child’s condition is at higher risk of deteriorating, requiring monitoring in a hospital. But there is little consensus about how closely such children should be monitored. Some children recover well, while others experience a neurological decline and need surgery to relieve brain swelling. Pediatric neurosurgeons have developed a risk scoring system intended to help determine whether a child with mild traumatic brain injury and an abnormal CT scan can be monitored safely in a general hospital ward or requires the increased surveillance of an intensive care unit. “We want to care for these children in the safest way possible and at the same time not place kids unnecessarily in ICUs if they don’t need that level of care,” says senior author David D. Limbrick, professor of neurological surgery and of pediatrics and director of the Division of Pediatric Neurosurgery at Washington University in St. Louis. “We have identified factors that indicate which of these patients are likely to experience neurological decline and require surgery and which are not. This information can help health-care providers decide where to place these children when they are admitted into the hospital.” For the study in JAMA Pediatrics, researchers plumbed data from more than 40,000 children evaluated from 2004 to 2006 at 25 North American hospital emergency departments. The information originally comes from a study conducted by the Pediatric Emergency Care Applied Research Network, which established the standard framework for deciding whether a child with a mild head injury should have a head CT scan. Researchers returned to this data set for guidance on how to handle the subset of children who receive CT scans and are shown to have abnormal findings on the scans. Of the 40,000 children enrolled in the study, 15,000 had CT scans following mild traumatic brain injury. Of these, 839 patients showed abnormalities on the CT scan, such as a brain bleed. These types of injuries are serious enough that some children will experience a neurological decline and need surgery to relieve swelling or pressure on the brain. In the United States, traumatic brain injury leads to almost 600,000 emergency room visits annually. Of new pediatric brain injury cases, more than 90 percent are determined to be mild. About one-third of the 50,000 to 60,000 children hospitalized each year due to head trauma have mild traumatic brain injury. Based on an analysis of the injuries these patients suffered and how they recovered, the investigators developed a risk score ranging from zero to 24 points, called the Children’s Intracranial Injury Decision Aid score. Higher scores indicate the patient is at higher risk of neurological decline and should receive increased monitoring. Lower scores mean a patient is at lower risk of neurological decline. A score of zero indicates the child is at very low risk. The chance that such a child would go on to experience a neurological decline that requires surgery is less than 1.5 percent, according to the analysis. As a general rule, children with scores of less than three points can safely be admitted to a general ward. Patients with higher scores should receive increased surveillance up to and including that provided in an ICU. “There is a lot of variability in how these patients are managed,” says first author Jacob K. Greenberg, a neurosurgery resident. “When we looked back at the data, we saw situations where children were perhaps put in the ICU but didn’t need to be there. And conversely, some patients were placed in a general ward when their risk factors suggested they needed closer monitoring. We are trying to develop this evidence-based tool to help guide and standardize this decision-making process.” The score is determined by four factors that the researchers found most predictive of patient outcomes. One factor is called the Glasgow Coma Scale (GCS), which is used to measure how alert and responsive a patient is after a blow to the head. Fifteen is the highest and best GCS score, meaning the patient can open his or her eyes spontaneously, follow commands to move different body parts and answer questions clearly and appropriately. While the GCS is based on a doctor’s interaction with a patient, the other three factors are determined based on an analysis of a CT scan. The biggest risk factors seen in a CT image are a depressed skull fracture and what is referred to as a midline shift, when the symmetrical structures of the brain are pushed off-center. The final risk factor is an epidural hematoma—a blood clot between the outer layer of the brain’s protective covering and the inside of the skull. Patients with mild traumatic brain injury who show these features on a CT scan and also have a lower GCS score are at high risk of experiencing a neurological decline and, according to the researchers, should be cared for in an ICU. “There are a variety of potential harms associated with sending a patient to an inappropriate location,” Greenberg says. “I think the most important is that if you send a child who needs the ICU into a general hospital ward, you risk missing a potential decline that could have been caught earlier. If the patient experiences new weakness or worsening mental status, for example, the goal is to intervene as quickly as possible to avoid permanent disability or even death. “On the other hand, if you send too many patients to the ICU, there are significant financial costs there, as well as emotional costs for the family,” he says. “Another concern is the limited space available in pediatric ICUs. Having children in the ICU who don’t need to be there is taking beds away from other patients who do need those resources.”

Itinerant ferromagnetism in cold Fermi gases with repulsive interactions is studied applying the Jastrow-Slater approximation generalized to finite polarization and temperature. For two components at zero temperature, a second-order transition is found at akF0.90 compatible with results of quantum-Monte-Carlo (QMC) calculations. Thermodynamic functions and observables, such as the compressibility and spin susceptibility and the resulting fluctuations in number and spin, are calculated. For trapped gases, the resulting cloud radii and kinetic energies are calculated and compared to recent experiments. Spin-polarized systems are recommended for effective separation of large ferromagnetic domains. Collective modes are predicted and tricritical points are calculated for multicomponent systems. © 2011 American Physical Society.
