Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Preparation and Performance Evaluation of a Self‐Generated Particle Plugging Agent Based on Thermosetting Resin

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A thermosetting in situ curing resin microsphere system has been developed. It has controllable phase transition time and particle size. This system addresses the current challenges of low strength, shear susceptibility, and short phase transition time in polymer microsphere blockers and thermoplastic particle blockers.

Selective Sequestration of Toxic NOx Gases by P‐Doped Graphene: A Density Functional Theory Study

open access: yesAdvanced Physics Research, EarlyView.
P‐doped graphene (P‐grap) is explored as an NOx sensor through DFT simulations. The analysis of its geometry, binding energies, electronic properties, and atom‐in‐molecule characteristics demonstrates that P‐grap is a selective sensor for NOx among a mixture of various gases.

Clean Cut (adaptive, multimodal surgical infection prevention programme) for low‐resource settings: a prospective quality improvement study

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
Clean Cut is a multimodal, adaptive, checklist‐based infection prevention programme designed to improve compliance with six critical perioperative infection prevention practices. After introducing the programme at five hospitals in Ethiopia, compliance with critical infection prevention standards significantly improved and the relative risk of ...
