Understanding the Chemical and Electronic Properties of Sub‐Monolayer TiO2 on High Surface Area Silica for Jet Fuel Synthesis Applications

open access: yesAdvanced Functional Materials, EarlyView.
Sub‐monolayer titania grafted onto mesoporous silica enables solvent‐free photocatalytic upgrading of furfural and cyclopentanone into jet fuel precursors. Advanced spectroscopic methods reveal tunable surface speciation, acidity, and bandgaps, enhancing catalytic efficiency.

Single‐Step Conversion of Metal Impurities in CNTs to Electroactive Metallic Nitride Nanoclusters for Electrochemical CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
A single‐step, low‐temperature co‐pyrolysis process removes encapsulated seed metal NPs (10–50 nm) from CNTs, redistributing them as surface‐anchored metal and metal–nitride NCs (1–1.5 nm). Herein, Ni3N NCs achieve an ultra‐low onset overpotential for CO2 reduction to CO with >98% Faradaic efficiency across 100–700 mA cm−2.

Engineering Porous Hollow Metal‐Poly(Heptazine Imide) Spheres: An Optimized Synthetic Strategy for Controlling Surface, Morphology, and Properties

open access: yesAdvanced Functional Materials, EarlyView.
Hollow poly(heptazine imide) spheres are prepared through a novel approach that integrates hard templating with ionothermal synthesis. This method enables precise control over surface area, pore volume, hydrophilicity, light absorption, band position, and metal composition. These tunable properties facilitate the customized design of semiconductors for

Group Gradings on Simple Lie Algebras of Type "A"

open access: yes, 2005
In this paper we describe all group gradings by a finite abelian group G of any Lie algebra L of the type "A" over algebraically closed field F of characteristic zero.
