Enhanced Nitric Oxide Electroreduction to Ammonia via Modulating Spin‐Polarization of Fe Single‐Atom Catalysts

Advanced Functional Materials, EarlyView.
A strategic spin‐polarization suppression in Fe single‐atom catalysts is proposed to enhance electrocatalytic reduction of NO to NH3. Employing a top‐down electrospinning strategy, self‐supported FeSAC with Fe‐N3S1 coordination structure and spin‐state transition is engineered from high‐spin to low‐spin.

A Widely-Separated, Highly-Occluded Companion to the Nearby Low-Mass T Tauri Star TWA 30 [PDF]

, 2010
We report the discovery of TWA 30B, a wide (~3400 AU), co-moving M dwarf companion to the nearby (~42 pc) young star TWA 30. Companionship is confirmed from their statistically consistent proper motions and radial velocities, as well as a chance ...

Co‐Delivery of Ca‐MOF and Mg‐MOF Using Nanoengineered Hydrogels to Promote In Situ Mineralization and Bone Defect Repair: In Vitro and In Vivo Analysis

Advanced Healthcare Materials, EarlyView.
Metal‐organic frameworks (MOFs) have been synthesized using calcium (Ca‐MOF), magnesium (Mg‐MOF), and as hybrids (Ca/Mg‐MOF) for bone healing applications. MOFs are integrated into hydrogel polymer networks for injectable, sprayable, and coating applications.

Synthesis and Stabilization of Support-Free Mesoporous Gold Nanoparticles

Nanomaterials, 2020
Porous gold nanoparticles (PGNs) are usually prepared in an immobilized form on a solid substrate, which is not practical in many applications. In this work, a simple method is reported for the preparation and stabilization of mesoporous gold particles ...

Tunicate‐Inspired Carboxymethyl Cellulose Hydrogel Filler for Treating Age‐Associated Vocal Fold Atrophy

Advanced Healthcare Materials, EarlyView.
The pyrogallol‐conjugated carboxymethylcellulose (CMC‐PG) hydrogel is applicated as a filler for the treatment of presbylaryngis, a vocal fold atrophy. CMC‐PG provides a bulking effect to the vocal folds. CMC‐PG is readily injectable and tissue adhesive, enabling sustained release of growth factor over long period.

Chemometric Methods Applied to Infrared and Raman Spectroscopy for Arboviruses Diagnosis: A Systematic Review With Meta-Analysis. [PDF]

Anal Sci Adv
ABSTRACT Arboviruses such as dengue, Zika, chikungunya and yellow fever share similar clinical manifestations, making differential diagnosis challenging, particularly in endemic regions with viral co‐circulation. Conventional laboratory methods present important limitations, including cross‐reactivity and reliance on specialized infrastructure. In this

Metronidazole‐Loaded Cyclodextrin Nanogels for Antibacterial Therapy and Microbiota Regulation in Periodontitis

Advanced Healthcare Materials, EarlyView.
A methacrylamide β‐cyclodextrin‐based nanogel (MACD nGel) is developed to load the antimicrobial drug Metronidazole (MNZ) for topical delivery for the treatment of periodontitis. It is demonstrated that cyclodextrin nanogel (nGel) loaded with metronidazole provides an efficient drug delivery route but also has potential clinical applications and offers
