Molecular Cross‐Linking of MXenes: Tunable Interfaces and Chemiresistive Sensing
Advanced Functional Materials, EarlyView.In this study, Ti3C2Tx MXenes are initially functionalized using oleylamine ligands to form stable dispersions in an organic solvent. Subsequently ligand exchange with α,ω‐diaminoalkanes enables cross‐linking, along with precise tuning of interfaces. This structural control translates into tunable charge transport and responsive VOC sensing, showing ...

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications
Advanced Functional Materials, EarlyView.Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

THE USE OF CARBON, HIGH-CHROMIUM STEELS FOR LINERS OF MUD PUMPS AND DRILLING RIGS
Известия высших учебных заведений: Нефть и газ, 2017 The paper shows that high temperature heating (from 1 100 to 1 170 0C) for the subsequent quenching of high-chromium steels of a martensitic-carbide class 95X18 and X12MFL provides structure to the metal base, which consist of high-carbon containing ...
