Advanced Science, EarlyView.By engineering the molecular order and thickness of PDMS layers, we reconcile the stickiness and slipperiness during bubble transport. AFM measurements and MD simulations further reveal how these nanoscale architectures tune hydrophobic interaction FHB and friction force f.

Advanced Science, EarlyView.High‐throughput quantum‐mechanical simulations reveal that amorphous carbon undergoes shear‐driven structural transformation into aromatic, graphene‐like interfaces. This mechanochemical process is governed by dopant chemistry: dopants with valency less than four promote the emergence of superlow‐friction amorphous graphene, whereas tetra‐valent ...

THE WORLD LUBRICANTS AND BASE OILS MARKET
, 2003 Sažetak Za globalnu industriju maziva 2002. i prva polovica 2003. godine bile su izazovne! Globalna se potražnja smanjila poradi slabih gospodarstava, ali i strukturalnih razloga. To osobito vrijedi za Sjevernu Ameriku i zapadnu Europu, a kao posljedica

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair
Advanced Science, EarlyView.A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration.

LUBRICANTS, MATERIALS AND LUBRICATION ENGINEERING
, 2002 Sažetak Prošlo stoljeće i kraj tisućljeća obilježeno je bogatim razvitkom tehnike, tehnologije, materijala i maziva. Međutim, zadnje godine prošlog stoljeća pokazale su da nije samo napredak u tehnologiji i ekonomski razvitak od društvenog značaja, nego

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 ...
