Advanced Solid Lubrication with COK‐47: Mechanistic Insights on the Role of Water and Performance Evaluation

open access: yesAdvanced Science, EarlyView.
This study is the first to report the solid lubrication performance of the newly discovered Ti‐based MOF (COK‐47) powder. COK‐47 exhibits a remarkably lowest and most stable coefficient of friction compared to typical solid lubricants. The lubrication mechanism involves water molecules from the air participating in tribochemical reactions, forming an ...

DNA Molecular Computing with Weighted Signal Amplification for Cancer miRNA Biomarker Diagnostics

open access: yesAdvanced Science, EarlyView.
A molecular computing approach is presented with weighted signal amplification. Polymerase‐mediated strand displacement is employed to assign weights to target miRNAs, reflecting the miRNAs’ diagnostic values, followed by amplification of the weighted signals using localized DNA catalytic hairpin assembly.

Modulating Iron Crystals with Lattice Chalcophile‐Siderophile Elements for Selective Dechlorinations Over Hydrogen Evolution

open access: yesAdvanced Science, EarlyView.
Lattice engineering of nFe0 crystals with chalcophile‐siderophile elements optimizes the iron microenvironment, enhancing hydrophobicity, electron transfer, and selective dechlorination efficiency while reducing hydrogen evolution reaction (HER). The Cu─S─nFe0 material shows a 20‐fold increase in dechlorination rate, a 150‐fold decrease in HER, and ...
