The effort to shift U.S. energy reliance from fossil fuels to renewable sources has spurred companies to reduce the cost and increase the reliability of their solar photovoltaics (SPVs). But thinner silicon is more susceptible to stress and cracking, leading one researcher from SunPower Corporation to mount a fundamental approach to systematically find stress and enable solutions for next-generation crystalline silicon SPV systems.

Self-Assembly of “S-Bilayers”, a Step Toward Expanding the Dimensionality of S-Layer Assemblies
Protein-based assemblies with ordered nanometer-scale features in three dimensions are of interest as functional nanomaterials but are difficult to generate. Here we report that a truncated S-layer protein assembles into stable bilayers, which we characterized using cryogenic-electron microscopy, tomography, and X-ray spectroscopy. Read more »
Two Novel Ultra-Incompressible Materials
Materials that are mechanically, thermally, and chemically stable at extreme conditions are valuable for aerospace engineering and fission/fusion research. Researchers have synthesized and characterized two such materials: Re2N and Re3N are both extremely incompressible. Read more »
ALS Reveals New State of Matter
ALS user groups from Princeton and Stanford have been making waves this past year with several high-profile papers and extensive news coverage of their work on a new state of matter embodied by so-called “topological insulators,” materials that conduct electricity only on their surfaces.

Mechanical Behavior of Indium Nanostructures
Indium is a key material in lead-free solder applications for microelectronics due to its excellent wetting properties, extended ductility, and high electrical conductivity. Researchers have investigated the small-scale mechanics of indium nanostructures. Read more »
Crosslink Density of Superabsorbent Polymers
Researchers from The Dow Chemical Company teamed with academic colleagues to conduct x-ray spectromicroscopy studies of superabsorbent polymers (SAPs), materials with a wide range of applications, including disposable baby diapers. Dow has been able to use the results to help develop the process technology for a new SAP-manufacturing plant. Read more »
