Article Abstract

Hydrogenation in amorphous silicon quantum dots (QDs) has a dramatic impact on the corresponding optical properties and band energy structure, leading to a quantum-confined composite material with unique characteristics. The synthesis of a-Si:H QDs is demonstrated with an atmospheric-pressure plasma process, which allows for accurate control of a highly chemically reactive non-equilibrium environment with temperatures well below the crystallization temperature of Si QDs.

Oxyphilic CeO mediated in situ reconstruction of amorphous/crystalline heterointerface with enhanced hydroxyl coverage and active sites leaching resistance for alkaline oxygen evolution.

Enhancing anodic hydroxyl (OH) coverage and suppressing leaching of active metal sites are essential for developing efficient and durable alkaline oxygen evolution reaction (OER) electrocatalysts. Herein, we propose amorphous cerium oxide (CeO)-mediated amorphous/crystalline heterointerface engineering to enhance OH coverage and leaching resistance in CeO/Mo-NiS for high-performance OER. CeO with an oxyphilic surface facilitates OH adsorption, promoting in situ reconstruction of NiS into nickel hydroxyl oxide (NiOOH) with significantly enhanced OH coverage and thereby accelerating OER kinetics.

This study evaluated the modification of corn starch using low-intensity pulsed electric field (PEF: 10 kV) combined with sodium salts (NaCl, NaCO₃, NaH₂PO₄) to investigate how pH and increased electrical conductivity affect starch structure. The study examined how salt pH and increased conductivity from electronegativity differences enhance polymer structural changes. NaCO₃ reduced amylose and long amylopectin chains (DP ≥ 37) by 18 %, confirmed by hydrodynamic radius (Rh) reductions for amylose (3.

In this study, infrared spectroscopy investigations in combination with DFT calculations were used to elucidate interactions between bosentan monohydrate (BOS) and sildenafil base (SIL) initiated under high energy ball milling. The research was focused mainly on the vibrational properties of their co-milled binary solid dispersions compared to the physical mixtures and single drugs. First, the stability and structure of sildenafil isomers were established.

Phase-Reconstruction of S-Doped (NiCo)WC for Efficient and Stable Oxygen Evolution Reaction Electrocatalysis.

Developing highly active and stable nonprecious electrocatalysts toward sluggish alkaline oxygen evolution reaction (OER) is essential for large-scale green hydrogen production via electrochemical water splitting. Here we report phase and surface co-reconstruction of S-doped (NiCo)WC nanoparticles into (NiCo)C with amorphous electroactive NiCoOOH layer for highly efficient alkaline OER by W dissolution and NiCo surface oxidation. The W dissolution results in the formation of Brønsted base WO ions, which electrostatically accumulate around electrode to promote water dissociation into abundant OH* intermediates, in situ constructing a locally strong alkaline microenvironment to facilitate OH* adsorption on NiCoOOH sites and trigger lattice-oxygen oxidation path.

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to manage pain and inflammation but are associated with gastrointestinal and cardiovascular risks, especially with COX-2 inhibitors. Topical delivery systems offer a safer alternative by minimizing systemic exposure; however, poor solubility and limited skin penetration remain challenges. Enhancing solubility through solid dispersion and incorporating it into a gel formulation may improve permeability and therapeutic effectiveness, addressing the need for safer and more efficient topical NSAID delivery.
