Research Highlight: Sulfur promoted Fe/N/C as highly efficient oxygen electrocatalyst for Zn-air batteries
Fe K-edge EXAFS analysis indicates that with the existence of S, the elements Fe, N, and C tend to form Fe–Nx-coordinated active sites.
Research Highlight: Roles of biogenic birnessite in controlling the mobility of heavy metals
Structure difference from abiotic birnessite and its environmental implications.
Research Highlight: Role of bifunctional catalysts for high performance Na-O2 batteries.
The local electronic and atomic structure of Mn and Pd at cycling stages of Na-O2 cell.
Research Highlight: Characterization of iron and sulfur in coal waste rock, Elk Valley, British Columbia, Canada.

Research Highlight: Enhance performance of P3HT:PCBM photovoltaic cells
Dielectric coily blocks, which were excluded from the P3HT crystalline structure, accumulated on the crystals surface without decreasing the crystal quality and formed hairy crystals.
Dehydrogenation of a BCC alloy of composition 52Ti-12V-36Cr doped with 4 wt.% Zr7Ni10 was studied. Prior to final dehydrogenation the FCC dihydride phase is becoming metastable..
Research Highlight: GIXRD study of perovskite solar cell
quantitatively investigate how the choice of metal oxide support (planar TiO2, mesoporous TiO2, or mesoporous Al2O3) affects the stability of the perovskite film in the presence of moisture.
Research Highlight: Pressure dependent pyrochlore iridate crystal structure
No evidence of crystal symmetry change over the range of temperatures (~6 to 300 K) and pressure (~0.1 to 17 GPa) where electronic and magnetic phase transitions have been reported.
Research Highlight: Low band gap organic solar cell
A new low band gapthermocleavable polymer showing stable photovoltaic properties
Research Highlight: GISAXS Quantum Dot
Cleavable Ligands Enable Uniform Close Packing in Colloidal Quantum Dot Solids uses a medium length thioamide ligand that is readily cleaved in a single chemical treatment, leading to quantum dot solids with uniformly packed domains 3 times larger than those observed in ligand-exchanged films.
Research Highlight: Hydrothermal biomass conversion
Examination of the dissolution, transformation, and gasification of pure cellulose and models of biomass residue under hydrothermal condition.
Research Highlight: GIXRD from perovskite solar cell
