Process Practice for Control of Boron Content in Boron Steels during Steelmaking

open access: yesTeshugang, 2013
The steelmaking flow sheet for boron steels such as 23 ~ 40MnB and 27MnTiB etc is 50 t EAF~LF + VD-CC process. It is available to increase the yield of boron to more than 90% by controlling EAF end [C], preliminary deoxidation by adding carbon powder ...

Janus‐Type Electrostatic Potential Gradient‐Activated Dynamic Zn2+‐Coordinating Nitrogen Sites in Molecularly Locked Nanocellulose Separators for Stable Zinc‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
A multifunctional benzimidazole‐terminated CNF separator is constructed via a PEI‐mediated covalent locking strategy, generating dense zincophilic sites that accelerate Zn2+ transport and desolvation while enabling uniform Zn (002) deposition and suppressing side reactions.

Defect Driven Electronic Structure Reconfiguration and Hierarchical Phonon Suppression in Ag2Se Thermoelectrics

open access: yesAdvanced Science, EarlyView.
Indium substitution in Ag2Se nanocrystals simultaneously tailors electronic structure and lattice dynamics. Fermi‐level upshift and band‐gap narrowing enhance electrical transport, while defect‐induced lattice softening intensifies phonon scattering and suppresses lattice thermal conductivity.
