Single‐Cell Hyperthermia: Diamond Quantum Thermometry Reveals Thermal Control of Macrophage Polarization

open access: yesAdvanced Materials, EarlyView.
Photothermal nanodiamonds with quantum sensing capabilities generate lysosome‐confined hyperthermia, enabling simultaneous temperature and radical detection via diamond sensing. This localized thermal and oxidative stress drives pro‐inflammatory (M1) macrophage polarization, revealing a new strategy for precision immunomodulation through subcellular ...

Ultra‐Improved Interfacial Strength Between Metallic Surface and Polyurethane via Cost‐Effective Anodizing Process

open access: yesAdvanced Materials Interfaces, EarlyView.
SAA significantly enhanced Al/PU bonding, increasing SLSS by up to 920% and fracture energy by 15 100% through optimized micro‐nano porous surfaces. RSM identified the optimal anodizing conditions, while ML confirmed sulfuric acid concentration and roughness as dominant predictors of strength.

Stabilizing Oxygen Vacancies in Plasmonic WO3‐x Semiconductor Nanosheets via Surface Reconstruction Approach

open access: yesAdvanced Materials Interfaces, EarlyView.
This study reports a surface reconstruction strategy to stabilize oxygen vacancies in plasmonic WO3‐x nanosheets. By engineering a dense WO3 passivation layer, the authors effectively trap interior vacancies against environmental reoxidation. This architecture preserves strong localized surface plasmon resonance effects, resulting in significantly ...

Rheological properties and rheokinetic of Hardening of modified thermoset oligomeres

open access: yesТонкие химические технологии, 2008
Modification of epoxy resins of silicon ethers (tethraetoxysilane – TEOS, and ethylsilicate – ET-40) was investigated. Phase diagrams of mixtures were given by the turbidity points method.

Revestimentos de alta camada obtidos com a modificação de resinas epóxi novolaca pela reação com organo-siloxano e catálise ácida

open access: yesQuímica Nova
Epoxy resins are an important class of thermostable polymers, widely used in structural applications or as adhesives. However, the low fracture resistance is their main weakness in many applications.

The 1-((diorganooxyphosphonyl)-methyl)-2,4- and -2,6-diamido benzenes [PDF]

open access: yes, 1989
1-((Diorgano oxyphosphonyl) methyl)-2,4- and -2,6-dinitro and diamino benzenes are prepared by nitrating an (organophosphonyl) methyl benzene to produce the dinitro compounds which are then reduced to the diamino compounds.
