Lubricant and antilubricant effects of water

Geotecnia, 1981
Referem-se estudos doutros autores sobre o efeito antilubrificante da água na fricção entre superfícies polidas de minerais de estrutura maciça (quartzo, feldspato, calcite) e o efeito lubrificante entre minerais de estrutura lamelar (micas, clorite, serpentina, talco).

Mastication‐Induced Electrical Stimulation Activates Prg4+ Chondroprogenitors for Osteoarthritis Therapy

Advanced Science, EarlyView.
This study presents a ″trash‐to‐treasure″ strategy that converts harmful joint overloads into beneficial electrical cues. The biodegradable MagPie, by providing piezoelectrical stimulation and releasing Mg2+ during mastication, exerts synergistic pro‐regenerative and anti‐inflammatory effects on Prg4+ cells via the ECM‐mediated FAK‐PI3K‐Akt axis ...

Flow characteristics and regime transitions in fluidization systems of Group C+ particles

AIChE Journal, EarlyView.
Abstract Fine and ultrafine particles are attractive for fluidized bed reactors because their high surface area benefits catalytic processes, but their cohesive nature complicates regime characterization. Nanoparticle modulation improves the flowability of Group C powders, yet their bubbling to turbulent transition remains unclear.

Data‐Driven Design of Bimodal Networked Dielectric Elastomers for High‐Performance Artificial Muscles

Advanced Intelligent Systems, EarlyView.
A data‐efficient artificial intelligence‐assisted framework, which integrates experimental data with machine learning, is developed for the design of bimodal networked dielectric elastomers (DEs) as advanced artificial muscles. It adopts neural networks to predict DEs’ mechanical properties and support vector machines to classify electromechanical ...

Selective Nitrate Transmembrane Transport Through Adaptive Weak C─H Bonding Cyanostilbene Water Channels

Angewandte Chemie, EarlyView.
Here we demonstrate that weak HB CH donor cyanostilbenes promote water/ion transport through their ability to form less‐ordered transient water channels within the lipid bilayer with increased water permeability and NO3−/ Cl− selectivity. ABSTRACT Transmembrane water transport strongly depends on how dynamic, translocating water clusters are stabilized

Concentric Rheostat Decoupled 3D Force‐Sensing Module for Smart Table Tennis Training

Advanced Intelligent Systems, EarlyView.
A 3D‐printed sensor array intrinsically decouples normal and shear forces through a unique concentric structural design. By integrating piezoresistive, sliding area‐varying capacitive, and concentric rheostat mechanisms, the 12‐sensor module achieves high‐resolution 3D force mapping without complex algorithms.

Clotrimazole‐loaded PLGA microparticles for local drug delivery to the vagina: Shape does matter

Animal Models and Experimental Medicine, EarlyView.
Clotrimazole‐loaded PLGA microparticles for intravaginal delivery. Abstract Background Intravaginal drug administration is the most promising strategy for treating vaginal infections to protect women's health, such as vulvovaginal candidiasis (VVC). However, conventional vaginal formulations in the clinic face challenges such as drug leakage and low ...
