Summary: The oxidation behavior and kinetics of partially crystalline Si2BC3N were studied at high temperatures, revealing weight loss due to gas release and the formation of loose oxide scales. Compared to completely amorphous Si2BC3N, partially crystalline Si2BC3N exhibited inferior oxidation resistance, possibly due to changes in superficial chemical compositions and reactivity during crystallization.

Summary: In this study, bulk heterojunction organic photovoltaics (OPV) were fabricated using different hybrid composites doped with a novel combination of PBDB-T:PCBM/hybrid-nanostructures. The structure and morphology of the W2C@rGO and Mo2C@rGO composites were established through a simple chemical reduction process. The incorporation of Mo2C@rGO and W2C@rGO hybrid into the active layers resulted in significantly improved power conversion efficiency (PCE) of 6.98% and 6.84%, respectively, compared to pure PBDB-T:PCBM and other materials. These findings suggest that the hybrid incorporated active layers facilitate efficient charge transport and extraction, leading to high-efficiency photovoltaic devices.

Summary: The 1.9 A resolution crystal structure of Mycoplasma Penetrans ferritin reveals that its ferroxidase center is positioned on the inner surface of ferritin rather than buried within each subunit's four-helix. This unique ferritin also shows lower iron oxidation activity and allows Fe2+ to enter via B-channels instead of the usual 3- or 4-fold channels, suggesting a novel iron oxidation mechanism.

Summary: The authors describe a protein interface redesign strategy for the self-assembly transformation of dimeric building blocks from hollow protein nanocage to filament, nanorod and nanoribbon. By adjusting the geometric arrangement of dimeric proteins, they demonstrate the potential to generate different protein materials in response to multiple external stimuli. This approach could lead to a deeper understanding of protein assembly and enable the construction of novel protein nanoarchitectures.

Summary: The extension peptide (EP) is a unique feature of mature plant ferritin and may have protease activity related to iron uptake and release. Our study on the crystal structure of ferritin-1 from Setaria italica revealed that the EP in this monocotyledon plant had a different folding pattern than other plant ferritins, suggesting a novel fold pattern for EPs in monocotyledons. Additionally, our study found additional iron atoms binding in the fourfold channels, highlighting the important role of these channels in iron diffusion.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
