Open AccessNano-frictional mechano-reinforcing porous nanowires scaffolds
Artificial biomaterials with dynamic mechano-responsive behaviors similar to those of biological tissues have been drawing great attention. In this study, we report a TiO2-based nanowire (TiO2NWs) scaffolds, whic...

Open AccessElectro-lubrication in Janus transition metal dichalcogenide bilayers
Lubrication induced by a vertical electric field or bias voltage is typically not applicable to two-dimensional (2D) van der Waals (vdW) crystals. By performing extensive first-principles calculations, we reve...

Control of the separation order of Au(III), Pd(II), and Pt(IV) achieved by site-controllable carboxyl-functionalized diethylaminoethyl celluloses
The separation and recovery of Au(III), Pd(II), and Pt(IV) is a challenge in hydrometallurgy, and finding good adsorbents is a way to solve this problem. In this work, two novel adsorbents, carboxymethyldiethy...
