Synthesis of Bi2Se3 Nanosheets with Applications in Photoelectrochemical Photodetectors

Small, EarlyView.
Hexagonal Bi2Se3 nanosheets are synthesized via a mild hydrothermal route with the assistance of a PVP surfactant. The as‐fabricated Bi2Se3 enables an excellent photoelectrochemical photodetector, which exhibits an apparent response across 334–578 nm. The Bi2Se3‐based devices deliver ultrafast (<70 ms) response and remarkable stability, opening a low ...

Synergic Magnetic–Dielectric Ni/Co‐Anchored Carbon Aerogels From Cellulose Nanofiber Scaffolds for Electromagnetic Shielding, Infrared Stealth, and Secure RFID Technologies

Small, EarlyView.
Ultralight Ni/Co‐anchored nanoporous carbon aerogels derived from TEMPO‐oxidized cellulose nanofibers integrate absorption‐dominated EMI shielding with infrared stealth. The hierarchical porous network provides dielectric/magnetic losses and suppresses thermal signatures.

Liquid Phase Backscattered Scanning Electron Microscopy of Bacillus subtilis Spores

Small Methods, EarlyView.
Graphene encapsulation enables liquid‐phase BSE‐SEM to visualize subsurface architecture of whole, hydrated Bacillus subtilis spores without staining. This approach is applied to visualize dormant spores and subsequent structural changes during spore germination, while imaging across a range of beam energies and Monte Carlo simulations provide a ...
