Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

Advanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Metal–Organic Framework‐Based Antimicrobial Touch Surfaces to Prevent Cross‐Contamination

Advanced Materials, EarlyView.
A MOF‐based antimicrobial door handle cover is developed. It completely inhibits the cross‐contamination of Gram‐positive bacterial species (Staphylococcus aureus, and Enterococcus faecalis), Gram‐negative bacterial species (Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii), and fungi (Candida albicans). Abstract Infection diseases

Tailored Particle Catalysts for Multistep One‐pot Chemoenzymatic Cascade in Pickering Emulsions

ChemCatChem, Volume 15, Issue 1, January 9, 2023., 2023
Chemoenzymatic cascades are enabled by combining particle catalysts and enzymes in water and Pickering emulsions in a sequential fashion. The benefit of such multistep one‐pot chemoenzymatic cascades is their high reactivity, selectivity, and recyclability without reaction incompatibility issues.

The $n$-queens problem [PDF]

arXiv, 2021
The famous $n$-queens problem asks how many ways there are to place $n$ queens on an $n \times n$ chessboard so that no two queens can attack one another. The toroidal $n$-queens problem asks the same question where the board is considered on the surface of the torus and was asked by P\'{o}lya in 1918.

Stress Response of Aspergillus niger Spores to Copper Surfaces and the Implications for Antifungal Surface Functionalization

Advanced Materials Interfaces, EarlyView.
This study investigates the antifungal efficacy of ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) on copper, brass, and steel surfaces. Using Aspergillus niger as a model, the research highlights a 99% reduction in spore viability on 9 µm structured copper surfaces due to enhanced copper ion release. Scanning electron microscopy

Atomic Layer Deposition of ZnO Coating on Biodegradable Fe‐Based Alloys

Advanced Materials Interfaces, EarlyView.
A biodegradable Fe69Mn30C1 alloy is coated with ZnO using atomic layer deposition at 100 °C. Coating thickness impacts surface roughness, wettability, and in vitro degradation while maintaining hydrophilicity. The ZnO coating exhibits significant antibacterial activity against Staphylococcus aureus, achieving an inhibitory rate of up to 99.2%, and can ...
