Syngas into Fuel: Optofluidic Solar Concentrators
Broad Funding Opportunity Announcement Project: Ohio State has developed an iron-based material and process for converting syngas—a synthetic gas mixture—into electricity, H2, and/or liquid fuel with zero CO2 emissions. Traditional carbon capture methods use chemical solvents or special membranes to separate CO2 from the gas exhaust from coal-fired power plants. Ohio State’s technology uses an iron-based oxygen carrier to generate CO2 and H2 from syngas in separate, pure product streams by means of a circulating bed reactor configuration. The end products of the system are H2, electricity, and/or liquid fuel, all of which are useful sources of power that can come from coal or syngas derived from biomass. Ohio State is developing a high-pressure pilot-scale unit to demonstrate this process at the National Carbon Capture Center.

Technical Area V (TA-V) transformation project close-out report.
Sandia National Laboratories (SNL) Technical Area V (TA-V) has provided unique nuclear experimental environments for decades. The technologies tested in TA-V facilities have furthered the United States Nuclear Weapons program and has contributed to the national energy and homeland security mission. The importance of TA-V working efficiently to produce an attractive and effective platform for experiments should not be underestimated. Throughout its brief history, TA-V has evolved to address multiple and diverse sets of requirements. These requirements evolved over many years; however, the requirements had not been managed nor communicated comprehensively or effectively. A series of programmatic findings over several years of external audits was evidence of this downfall. Today, these same requirements flow down through a new TA-V management system that produces consistently applied and reproducible approaches to work practices. In 2008, the TA-V department managers assessed the state of TA-V services and work activities to understand how to improve customer interfaces, stakeholders perceptions, and workforce efficiencies. The TA-V management team initiated the TA-V Transformation Project after they deemed the pre-June 2008 operational model to be ineffective in managing work and in providing integrated, continuous improvement to TA-V processes. This report summarizes the TA-V Transformation Project goals, activities, and …

Titanium-Alloy Power Capacitor: High-Power Titanate Capacitor for Power Electronics
ADEPT Project: There is a constant demand for better performing, more compact, lighter weight, and lower cost electronic devices. Unfortunately, the materials traditionally used to make components for electronic devices have reached their limits. Case Western is developing capacitors made of new materials that could be used to produce the next generation of compact and efficient high-powered consumer electronics and electronic vehicles. A capacitor is an important component of an electronic device. It stores an electric charge and then discharges it into an electrical circuit in the device. Case Western is creating its capacitors from titanium, an abundant material extracted from ore which can be found in the U.S. Case Western's capacitors store electric charges on the surfaces of films, which are grown on a titanium alloy electrode that is formed as a spinal column with attached branches. The new material and spine design make the capacitor smaller and lighter than traditional capacitors, and they enable the component to store 300% more energy than capacitors of the same weight made of tantalum, the current industry standard. Case Western's titanium-alloy capacitors also spontaneously self-repair, which prolongs their life.

Towards an Understanding of the Role of Aragonite in the Mechanical Properties of Nacre
Nacre, also known as mother-of-pearl, is a biocomposite material that exhibits higher strength and fracture toughness than its component materials. It derives its strength from the brick-and-mortar layering of aragonite (CaCO{sub 3}) platelets and organic binder. It is believed that the protein binder helps redistribute the stress throughout all tablets for optimal mechanical performance. In this study, we attempt to measure the mechanical properties of aragonite within nacre and compare them to bulk aragonite and bulk nacre and understand the redistribution of stresses. Here we show that x-ray diffraction techniques are useful for isolating and measuring strain of crystallites within a composite material. Our results show that the apparent stiffness of aragonite varies with crystallographic directions and is higher than the stiffness of bulk nacre in all cases, meaning that aragonite tablets are exposed to less than the average bulk stress. The average force applied to the bulk sample is partitioned between the aragonite and the binder, so that the protein layer bears as much as 27.2% of the total applied force. Different crystallographic directions exhibit behaviors different than bulk aragonite or bulk nacre. These are related to texture of aragonite platelets (i.e. preferred orientations within nacre). By examining nacre, …

Transistors for Electric Motor Drives: High-Performance GaN HEMT Modules for Agile Power Electronics
ADEPT Project: Transphorm is developing transistors with gallium nitride (GaN) semiconductors that could be used to make cost-effective, high-performance power converters for a variety of applications, including electric motor drives which transmit power to a motor. A transistor acts like a switch, controlling the electrical energy that flows around an electrical circuit. Most transistors today use low-cost silicon semiconductors to conduct electrical energy, but silicon transistors don’t operate efficiently at high speeds and voltage levels. Transphorm is using GaN as a semiconductor material in its transistors because GaN performs better at higher voltages and frequencies, and it is more energy efficient than straight silicon. However, Transphorm is using inexpensive silicon as a base to help keep costs low. The company is also packaging its transistors with other electrical components that can operate quickly and efficiently at high power levels—increasing the overall efficiency of both the transistor and the entire motor drive.

Transverse Coherence of the LCLS X-Ray Beam
Self-amplifying spontaneous radiation free-electron lasers, such as the LCLS or the European X-FEL, rely on the incoherent, spontaneous radiation as the seed for the amplifying process. Though this method overcomes the need for an external seed source one drawback is the incoherence of the effective seed signal. The FEL process allows for a natural growth of the coherence because the radiation phase information is spread out within the bunch due to slippage and diffraction of the radiation field. However, at short wavelengths this spreading is not sufficient to achieve complete coherence. In this presentation we report on the results of numerical simulations of the LCLS X-ray FEL. From the obtained radiation field distribution the coherence properties are extracted to help to characterize the FEL as a light source.
