New Wine in Old Bottles: Fully Substituted Arylthio Effect Realizes High‐Efficiency Purely Organic Phosphorescence Light‐Emitting Diode With Single and Ultra‐Stable Spectra Under 2000 cd m−2

Aggregate, Volume 6, Issue 4, April 2025.
Benefiting from the fully substituted arylthio effect, pure organic emitter 6S has the most obvious aggregation‐induced phosphorescence characteristic, the largest spin orbital coupling value, and the smallest the energy gap between S1 and T1. Consequently, a high maximum external quantum efficiency of 15.3% and ultra‐stable spectra under high ...

Pore-size tunable mesoporous zirconium organophosphonates with chiral (L)-proline for enzyme adsorption

, 2007
Mesoporous zirconium organciphosphonates with a tunable mesopore (pore diameter: from 4.8 to 16.3 nm) were synthesized through co-condensation of ZrCl4 and 1-phosphomethylproline (H3PMP) with the aid of organic additives in the presence of an anionic ...

Effects of glyphosate on antibiotic resistance in soil bacteria and its potential significance: A review

Journal of Environmental Quality, Volume 54, Issue 1, Page 160-180, January/February 2025.
Abstract The evolution and spread of antibiotic resistance are problems with important consequences for bacterial disease treatment. Antibiotic use in animal production and the subsequent export of antibiotic resistance elements in animal manure to soil is a concern.

Engineering a Mesoporous Silicon Nanoparticle Cage to Enhance Performance of a Phosphotriesterase Enzyme for Degradation of VX Nerve Agent

Advanced Science, Volume 11, Issue 48, December 26, 2024.
A porous silicon nanocage encapsulating phosphotriesterase variant L7ep‐3a is evaluated for nerve agent detoxification. By tuning the physicochemical properties of the enzyme–porous silicon nanoconstruct, enhanced catalytic activity, and operational stability are achieved compared to the free enzyme.

The Prospect of Selective Recognition of Nerve Agents with Modular Basket-like Hosts. A Structure-Activity Study of the Entrapment of a Series of Organophosphonates in Aqueous Media

, 2013
We designed, prepared, and characterized three cup-shaped cavitands 1-3 for trapping organophosphonates (O=PR(OR')(2), 118-197 A3) whose shape and size correspond to G-type chemical warfare agents (132-186 A(3)).

Mono‐Exponential Current Attenuation with Distance Across 16 nm Thick Bacteriorhodopsin Multilayers

Advanced Functional Materials, Volume 34, Issue 48, November 26, 2024.
Electronic charge transport through multilayers of the protein bacteriorhodopsin (bR) shows an intriguing, mono‐exponential conductance attenuation with layer thickness up to ≈16 nm. A measured small attenuation coefficient β ≈ 0.8 nm−1 indicates efficient long‐range transport, which is mostly limited by charge injection at the interfaces. Abstract The

Synthesis of Mesostructured and Mesoporous Aluminum Organophosphonates Prepared by Using Diphosphonic Acids with Alkylene Groups

, 2016
Mesostructured and mesoporous aluminum organophosphonates (AOPs) with 2-D hexagonal structures (AOP-2) can be synthesized by using alkylene diphosphonic acids in the presence of alkyltrimethylammonium (CnTMA) surfactants.

Catalytic Activation of Bis(2,2,2‐trifluoroethyl) Phosphite with Hf(IV) for the Synthesis of Mixed Dialkyl Phosphites

Advanced Synthesis &Catalysis, Volume 366, Issue 18, Page 3822-3828, September 17, 2024.
Abstract We developed a second generation of Lewis acid catalyst enabling selective and user‐friendly phosphonylation of diverse alcohols. This one‐pot method utilizes P(III) reagent bis(2,2,2–trifluoroethyl) phosphite under mild conditions. Exploring the influence of metal selection in Lewis acid catalysts revealed four highly active complexes for ...
