Chemoenzymatic Synthesis Of Acyl Coenzyme-A Molecules

Acyl-CoAs is involved in both primary and secondary metabolism; it is an important intermediate molecule for in vitro enzymatic assays in research. Current chemical methods to generate acyl-CoAs rely on chemical ligation of carboxylic acids to commercially available coenzyme A molecule by the use of peptide coupling reagents. These couplings are inefficient and the final product is hard to purify. This process of acyl-CoA synthesis is therefore expensive.

Helmet Apparatus

Traumatic brain injury is a major public health issue in the world, especially as related to sports-related accidents in particular as related to football head injuries. Athletes report almost four million sports-related concussions a year in the U.S. alone. A major portion of head injuries are caused by torque (rotational acceleration) in a collision. Current market approaches do not provide adequate protection against the impact caused by torque. To address this problem, researchers at the University of California, Berkeley, have developed a reusable and effective helmet system with optimal elasticity and flexibility and material structure to accommodate the twisting impact of a collision by the helmet rather than against the head. Experiments in silico suggest significant improvement over the state of the art with respect to linear and angular accelerations.

Method For Fabricating Two-Dimensional Protein Crystals

2D crystalline materials possess high surface area-to-volume ratios, light and can be very porous. These properties have rendered synthetic 2D materials immensely attractive in applications including electronics, sensing, coating, filtration and catalysis. The rational design of self-assembling 2D crystals remains a considerable challenge and a very active area of development. The existing methods for the bottom-up fabrication of biological or non-biological 2-D crystalline materials are not generalizable and scalable. 2D protein design strategies, in particular, require extensive computational work and costly protein engineering. In addition, these strategies have low success rates, the resulting materials contain large defects, and are multi-layered and therefore not appropriate for scaling or materials-applications. Moreover, these strategies often require the presence of lipids for supported assembly.

Microvascular Exchangers for Heat and Mass Transfer

Micro-structured materials or materials with an embedded microvasculature have advanced the fields of heat exchange, chemical analysis, flow chemistry, fuel cells and carbon capture. In the field of heat exchange, micro-structured composites are being developed to enable fluid-based heat transfer. Such composites may be used in aircraft structures and the ability of the composite to regulate its temperature would decrease an aircraft’s lifecycle costs. In the field of carbon capture, carbon dioxide may be pumped through the microvasculature and a solution of monoethanolamine (MEA) would circulate around the microvasculature. The formation of a carbamate with the MEA and CO2 enables carbon capture. Researchers at the University of California, Irvine have designed a novel microvascular exchanger and this microvascular exchanger has a high heat and mass transfer coefficient when compared to other micro-structured materials. .

Mechanical Linear Actuator That is Low Cost and High Performance

Linear motion is an essential mechanical property used in huge variety of applications. There are multiple ways to create linear motion, including screws, cams, pulleys, pneumatic and hydraulic actuation. Overall performance of these linear actuators can be defined in terms of cost, scale, speed, and efficiency. Current actuators are strong in one or two of these performance categories, which limits their use to specific applications.   UC Berkeley researchers have designed a novel linear actuator that is strong across all four performance categories. The clever Berkeley design provides fast and efficient actuation, and its unique structure is scalable for multiple applications. It is especially conducive to applications that have tight space confines, need a large degree of displacement at a high rate, and are cost constrained.

High Performance, Rare Earth-free Supermagnetostrictive Structures and Materials

Magnetostrictive materials convert magnetic fields into mechanical strain and vice versa. They are widely used in sensors, actuators, electrical motors and other technological devices. The materials currently used for these applications are relatively inefficient (e.g. nickel or iron-aluminum alloys) or are very expensive (e.g. Terfenol-D). To address these challenges, researchers at the University of California, Berkeley, have developed a process framework using incipient martensitic transformations to achieve useful magnetostriction in relatively inexpensive materials. Early laboratory models suggest the Berkeley materials have comparable behavior to rare earth-based counterparts, with preliminary data to suggest superior performance than both rare earth-based and rare earth-free materials on the market today.

Low-Pressure High-Capacity Storage System for Sustainable Hydrogen Economy

Hydrogen-fueled cell vehicles could gain ground as global researchers develop better processes to produce hydrogen economically from sustainable resources like solar and wind. On an energy-to-weight basis, hydrogen has nearly three times the energy content of gasoline (120 megajoule or MJ, per kilogram or kg, for hydrogen, versus 44 MJ/kg for gasoline). One problem is storing enough hydrogen on-board to achieve a reasonable driving range of 300 to 400 miles. On energy-to-volume basis, hydrogen takes up nearly three times the volume of gasoline (8 MJ/liter for cryogenic liquid hydrogen versus 32 MJ/liter for gasoline). Another problem is related to next-generation solid absorbents like metal hydrides, which typically show weakness in terms of the amount of gas that can be absorbed and delivered. To address these problems, researchers at the University of California, Berkeley, and Lawrence Berkeley National Laboratory, have developed a composite material using nanostructured metal hydrides that is capable of storing three times more hydrogen per volume at room temperature than a comparable cryogenic liquid hydrogen tank. Furthermore, low hydrogen pressures during absorbing and desorbing have been achieved. This represents a significant economic and safety advantage over technologically complex and costly high-pressure (10,000 psi) hydrogen tanks commonly used in mobile hydrogen storage applications today.
