Oral Astilbin Nanogels Modulate Senescence‐Associated CD4+ T Cells and Promote Treg Induction in Aged Mice with Colitis

Advanced Science, EarlyView.
Fluorinated β‐glucan/pectin nanogels enable colon‐targeted oral delivery of astilbin through gastrointestinal protection, β‐glucanase‐responsive release, mucus penetration, and prolonged retention. The released astilbin attenuates senescence‐associated features of CD4+ T cells and promotes Treg responses, while the nanogel matrix modulates the gut ...

Effects of Plasma Power on By-Product Gas Formation from CHF₃ and CH₂F₂ Process Gases in Semiconductor Etching Processes

Applied Sciences
In semiconductor manufacturing, fluorinated gases such as CHF3 and CH2F2 are widely used as process gases for plasma etching and cleaning. However, their decomposition within the plasma environment leads to the formation of secondary fluorinated by ...

Cardiotoxicity of Freon among refrigeration services workers: comparative cross-sectional study

Environmental Health, 2009
Background Freon includes a number of gaseous, colorless chlorofluorocarbons. Although freon is generally considered to be a fluorocarbon of relatively low toxicity; significantly detrimental effects may occur upon over exposure.

Dual‐Functional Membranes With Interfacial MXene/PFSA Nanoarchitectures for Low Hydrogen Permeation in Water Electrolysis and Reduced Vanadium Ion Crossover in Flow Batteries

Advanced Science, EarlyView.
A PFSA/MXene composite membrane is developed for both PEMWE and VRFB applications. MXene incorporation simultaneously enhances proton conductivity and suppresses hydrogen/vanadium crossover. The interaction between MXene functional groups and PFSA's –SO3H reduces the proton diffusion barrier via hydrogen‐bonding networks, while the disordered ...

Modeling the liquid-liquid equilibria of water plus fluorocarbons with the cubic-plus-association equation of state

, 2007
Fluorocarbons (FCs) are a family of chemicals that are composed primarily of carbon and fluorine. They present weak intermolecular and strong intramolecular interactions, which confers them unusual thermophysical properties.

Ultrasound‐Triggered piRNA Delivery Using Biomimetic Phase‐Changeable Nanoparticles for Theranostics of Myocardial Infarction

Advanced Science, EarlyView.
A biomimetic ultrasound‐responsive piRNA delivery nanoparticle platform (piR‐NPs) enables targeted delivery and ultrasound (US)‐triggered release of piR‐1873 in infarcted myocardium. The released piR‐1873 suppresses Usp2‐mediated RIP1/RIP3/MLKL necroptosis, reduces myocardial injury and fibrosis, and promotes cardiac functional recovery, providing a ...

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

BMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

Modification of Diamond Conditioner with V-SAM Coatings for Corrosion Prevention During Metal CMP

International Journal of Electrochemical Science, 2013
In the present work, the vapor phase-self assembled monolayers made from two different precursors, 1-dodecanethiol (DT) and perfluoroctyltrichlorosilane (FOTS), were prepared on a nickel surface under optimized conditions [2].
