Ecofriendly Sunlight‐Mediated Nontoxic Bimetallic Nanoparticles: Synthesis, Reusable Catalytic Membrane, and Biosensor Applications

open access: yesAdvanced Science, EarlyView.
A novel sunlight‐driven synthesis produces Ag–Cu bimetallic nanoparticles (NPs) in just 10 min using nontoxic surfactants. These high‐quality NPs show excellent catalytic activity, functioning as reusable polytetrafluoroethylene (PTFE) and activated carbon fiber (ACF) supported catalysts for efficient conversion of p‐nitrophenol to p‐aminophenol, and ...

Extinction in agent-based and collective models of bet-hedging [PDF]

open access: yesarXiv
Bet-hedging is a phenotype diversification strategy that combines a fast-growing vulnerable phenotype with a slow-growing resistant phenotype. In environments switching between favorable and unfavorable conditions, bet-hedging optimizes growth and reduces fluctuations over a long time, which is expected to reduce extinction risk.

Self‐Powered UV Dual‐Band Photodetector Based on Cs3BiCl6/GaN Heterojunction for Logical Operation and Encrypted Photo‐Communication

open access: yesAdvanced Science, EarlyView.
Utilizing the special dual‐band absorption characteristics of Cs3BiCl6 and its strong surface‐charge recombination behavior, a self‐powered UV dual‐band photodetector based on Cs3BiCl6/GaN heterojunction is developed. As a result, the photodetector exhibits excellent specific detectivity of 1.23 × 1012 Jones and ultrafast response speed of τr/τf = 28 ...

Current updates of CRISPR/Cas9‐mediated genome editing and targeting within tumor cells: an innovative strategy of cancer management

open access: yesCancer Communications, Volume 42, Issue 12, Page 1257-1287, December 2022., 2022
Abstract Clustered regularly interspaced short palindromic repeats‐associated protein (CRISPR/Cas9), an adaptive microbial immune system, has been exploited as a robust, accurate, efficient and programmable method for genome targeting and editing. This innovative and revolutionary technique can play a significant role in animal modeling, in vivo genome

Solvated PbI2 Clusters Preceding the Crystallization of Lead Halide Perovskites–a UV/VIS In Situ Study

open access: yesAdvanced Electronic Materials, EarlyView.
This work focuses on the crystallization dynamics in lead iodide perovskite films: In situ UV absorption spectroscopy reveals a PbI2‐DMF solvated (PDS) phase before nucleation, influencing perovskite formation. PDS clusters act as nucleation seeds, linking precursor solution concentration to crystallization.
