Semiclassical atom theory applied to solid-state physics
, 2016 Using the semiclassical neutral atom theory, we extend to fourth order the modified gradient expansion of the exchange energy of density functional theory. This expansion can be applied both to large atoms and solid-state problems. Moreover, we show that

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.Centimeter‐scale macroporous alumina monoliths with hollow skeletons were prepared via a phase‐separation‐assisted metal salt sol–gel route. They exhibit high diffuse reflectance across the UV–Vis–NIR range, demonstrating potential as lightweight optical diffusers.

High-temperature catalyst supports and ceramic membranes: Metastability and particle packing [PDF]
, 1997 Parameters and/or processes responsible for the stability of catalyst supports and ceramic membranes are discussed. Two major parameters/processes were identified which are responsible for the stability of sol-gel derived nanostructured oxides at ...

ChemSusChem, Volume 18, Issue 24, December 13, 2025.(Hemi)celluloses, abundant in lignocellulosic biomass, can be hydrolyzed and dehydrated into furanics like 5‐hydroxymethylfurfural (5‐HMF) and levulinic acid. Despite its potential, 5‐HMF production remains limited by inefficiencies, notably humin formation.

Improving reaction uniformity of high‐loading lithium‐sulfur pouch batteries
Carbon EnergyLithium‐sulfur batteries (LSBs) have garnered attention from both academia and industry because they can achieve high energy densities (>400 Wh kg–1), which are difficult to achieve in commercially available lithium‐ion batteries.

New insight into artifactual phenomena during in vitro toxicity assessment of engineered nanoparticles: Study of TNF-α adsorption on alumina oxide nanoparticle [PDF]
, 2013 International audienceBiomolecules can be adsorbed on nanoparticles (NPs) and degraded during in vitro toxicity assays. These artifactual phenomena could lead to misinterpretation of biological activity, such as false-negative results.
