Ag/Co3O4–C nanocomposites display well‐resolved lattice fringes and synergistic Ag/Co3O4 heterointerfaces that enhance charge transfer and active‐site exposure. The structural design enables superior bifunctional ORR/OER performance in alkaline media by promoting efficient adsorption and turnover of oxygen intermediates within an optimized ...

Evaluation of potassium titanate as a component of alkaline fuel cell matrices [PDF]
Various forms of potassium titanate were found to have almost complete resistance to chemical attack in 45 wt % KOH at 150 C (423 K) for up to 9600 hours. Electron microscopy and X-ray diffraction disclosed important differences with respect to fibricity

An external electric field‐enhanced photocatalytic system is developed using interdigitated electrodes with 100 µm spacing to overcome the liquid‐phase limitations of traditional PEC. The induced high‐intensity electric field effectively drives the directional migration of charge carriers under low voltage. This strategy significantly suppresses charge

High performance, high density hydrocarbon fuels [PDF]
The fuels were selected from 77 original candidates on the basis of estimated merit index and cost effectiveness. The ten candidates consisted of 3 pure compounds, 4 chemical plant streams and 3 refinery streams. Critical physical and chemical properties

Combustion mechanisms of coal slurry fuels.
The formation and subsequent burnout behaviour of coal slurry fuel chars has been studied using a suspended single droplet technique and solid sampling techniques in large turbulent diffusion flames. Both these techniques yielded comparable results on the structure of carbonaceous residues from a range of coal slurry fuels containing coals of different

Aqueous ammonium‐ion batteries leverage hydrogen‐bond‐mediated NH4+ storage in tunable transition metal compounds. Despite progress in Mn‐, V‐, Mo‐, and W‐based compounds, 2D LDHs, and MXenes, challenges like structural instability and slow kinetics persist. Future advances require robust host design, mechanistic understanding via operando studies, and

Preparation and characterization of metakaolin-based Ag0-containing sorbent beads for iodine capture
We report metakaolin (MK)-based sorbents with high metallic silver(Ag0) content for maximizing iodine uptake per unit volume. Spherical beads were fabricated by a droplet method using slurries with various Na/M (M = Na + Al + Si) and H2O/Na2O molar ...

This study introduces a multidimensional framework integrating electrical performance, cost, and life cycle assessment for 140 real and virtual battery cells. Results show that LFP offers low emissions and costs, sodium‐ion excels in resource efficiency, and pouch housings and higher energy densities effectively reduce environmental burdens.
