POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

open access: yesAdvanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Development of numerical models for Monte Carlo simulations of Th-Pb fuel assembly

open access: yesE3S Web of Conferences, 2017
The thorium-uranium fuel cycle is a promising alternative against uranium-plutonium fuel cycle, but it demands many advanced research before starting its industrial application in commercial nuclear reactors.

Bioinspired, Mitochondria‐Targeted Single‐Atom Nanozyme Enhances Bone Regeneration by Reprogramming Stem Cell Energy Metabolism​

open access: yesAdvanced Materials, EarlyView.
A bioinspired nanozyme—triphenylphosphonium (TPP)‐dendritic mesoporous silica nanoparticle (DMSN)‐Fe/Cu—mimics mitochondrial complex IV and targets mitochondria to regulate cellular energy metabolism. This approach markedly boosts bone regeneration in vivo, as demonstrated by enhanced bone volume and mineral density in critical‐sized bone defects rat ...

Fuel cell life improved by metallic sinter activation after electrode assembly welding [PDF]

open access: yes, 1967
Technique improves the service life of fuel cell electrodes. The welding is done before the metallic sinter is activated by depositing finely divided metal within the sinter structure from a solution with corrosion inhibiting ions. The activator solution

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

open access: yesAdvanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...
