Enhancing the Chemical Reactivity of Graphene through Substrate Engineering

Small, EarlyView.
This review highlights methods to enhance the reactivity of graphene through substrate engineering, focusing on strain and charge doping. Strains induced by nanoparticles, metal crystal orientations, or stretchable polymers increase the reactivity of graphene.

Surface Engineering of Ti3C2Tx MXenes via Silanol Functionalization for Improved Electrochemical Performance

Small, EarlyView.
This study explores the covalent functionalization of Ti3C2Tx using 5,5′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine in different solvents, revealing that only m‐xylene enables effective covalent bonding, ensuring structural stability and preventing layer swelling.

Tuning Optoelectronic Properties and Photoelectrochemical Performance of β‐TaON via Vanadium Doping

Small, EarlyView.
Vanadium‐doped β‐TaON is studied to elucidate how controlled cation substitution modulates crystal and electronic structures and photoelectrochemical performance. Moderate vanadium incorporation (<10 at.%) retains phase purity, narrows the bandgap, and improves charge transport, whereas excessive doping (>10 at.%) induces secondary phases that suppress

MXene 3D‐AJP: Three‐Dimensional Well‐Oriented Freeform Networks of 2D MXene Nanosheets via Aerosol‐Based 3D Printing

Small, EarlyView.
This study presents an additive‐free aerosol jet 3D printing technique for assembling 2D MXene nanosheets into complex, customizable, high‐aspect‐ratio 3D microarchitectures without binders. By leveraging real‐time ink thickening, the authors also fabricate 3D microsupercapacitors with interdigitated electrodes that holds breakthrough device areal ...

Engineering Metastability in Atomic Layer Deposition: Polymorph and Valence Control

Small, EarlyView.
This work presents strategies for stabilizing two types of metastable phases: structural polymorphs and multivalence states via ALD. These approaches focus on lowering the energy barriers required for metastable phase formation, enabling access to metastable states beyond the thermodynamic limits imposed by the low‐temperature conditions of ALD.

Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

Environmental Toxicology, EarlyView.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have
