Advanced Healthcare Materials, EarlyView.This study characterizes the presence of microplastics in human normal gastric, para‐tumor, and gastric tumor tissue and confirms the association between microplastic exposure and lymph node metastasis in gastric cancer. This study explores the transcriptomic changes induced by microplastic exposure, laying the foundation for further investigation into

Talc-based cementitious products: Effect of talc calcination
Journal of Asian Ceramic Societies, 2015 This study reports the use of calcined talc for cementitious products making. The calcination is used to enhance the availability of magnesium from talc to react with phosphate for cement phase formation.

Dislocation density and graphitization of diamond crystals [PDF]
, 2002 Two sets of diamond specimens compressed at 2 GPa at temperatures varying between 1060 K and 1760 K were prepared; one in which graphitization was promoted by the presence of water and another in which graphitization of diamond was practically absent.

Origins of Graphite Resistivity: Decoupling Stacking Fault and Rotational Misorientation
Advanced Science, EarlyView.Interfacial dislocations critically influence interlayer transport in van der Waals (vdW) materials, yet quantifying their individual contributions remains challenging. We measure graphite's c‐axis resistivity and develop a decoupling strategy, revealing a resistivity ratio of ∼4507:74:1 for rotational misorientations, stacking faults, and AB stacking,
