Combined Spatially Resolved Characterization of Antireflection and Antisoiling Coatings for PV Module Glass.

Characterization of photovoltaic (PV) module materials throughout different stages of service life is crucial to understanding and improving the durability of these materials. Currently the large-scale of PV modules (>1 m) is imbalanced with the small-scale of most materials characterization tools (≤1 cm). Furthermore, understanding degradation mechanisms often requires a combination of multiple characterization techniques.

Molecular dynamics simulation of zirconium tungstate amorphization and the amorphous-crystalline interface.

Classical molecular dynamics (MD) simulations were performed to provide a conceptual understanding of the amorphous-crystalline interface for a candidate negative thermal expansion (NTE) material, ZrWO. Simulations of pressure-induced amorphization at 300 K indicate that an amorphous phase forms at pressures of 10 GPa and greater, and this phase persists when the pressure is subsequently decreased to 1 bar. However, the crystalline phase is recovered when the slightly distorted 5 GPa phase is relaxed to 1 bar.

The proteomics of senescence in leaves of white clover, Trifolium repens (L.).

A proteomics approach has been used to study changes in protein abundance during leaf senescence in white clover. Changes in cell ultrastructure were also examined using transmission electron microscopy. The most obvious ultrastructural changes during senescence occurred in chloroplasts, with progressive loss of thylakoid integrity and accumulation of osmiophilic globules in the stroma.
