As a promising new-star electrocatalyst, transition metal phosphide (TMP) has been widely applied in electrocatalytic hydrogen and oxygen evolution reactions (HER OER). However, the current catalytic activity stability are unsatisfactory. Herein, we started from optimizing geometric electronic structure of catalyst, choosing FeCo Prussian blue analogues (PBAs) with rich pores as precursors epitaxially grown Ni(OH)2 then connecting them though graphene oxide (GO) by electrostatic interaction,...
Nanotribology has been given increasing attention by researchers in pursuing the nature of friction. In present work, an approach that combines supramolecular assembly and nanotribology is introduced. Herein, nanotribological study was carried out on seven template networks [namely, hydrogen bond induced tricarboxylic acids van der Waals force hexaphenylbenzene (HPB) derivatives]. The networks, as well host–guest assemblies molecules different forces, were constructed highly oriented...
Fullerenes have been recognized as good candidates for solid lubricants. In this study, the microscale superlubricity of fullerene derivatives was accomplished by construction regular host–guest assembly structures. Herein, structures were successfully constructed on a highly oriented pyrolytic graphite (HOPG) surface introducing macrocycles templates and explicitly revealed scanning tunneling microscopy (STM). Meanwhile, nanotribological properties assemblies measured using atomic force...
This study was to investigate the nanomechanical and nanotribological properties of polyether ether ketone (PEEK)-based composites for biomedical applications gain a fundamental understanding effects carbon fibers in carbon-fiber-reinforced PEEK (CFRPEEK) on mechanical wear performance microscale. Nanoindentation tests with Berkovich indenter nanoscratch experiments diamond stylus were performed CFRPEEK samples. The nanowear features mechanisms tested samples analyzed using 3D white-light...

On-surface synthesis has gradually become a prevalent approach to constructing two-dimensional functional monolayers on various substrates. In the present work, of self-assembled (SAMs) benzothiazole derivatives was conducted at liquid/solid interface for first time. Two kinds nanostructures were achieved highly oriented pyrolytic graphite (HOPG) surface via condensation reaction between aromatic aldehyde and 2-aminothiophenol (ATP). The formation thiazole-based self-assemblies revealed by...
Titanium (Ti) and its alloys are widely used in biomedical devices. As biomaterials, the blood compatibility of Ti is important needs to be further improved provide better functionality. In this work, we studied suitability zirconia (ZrO₂) particle reinforced poly-ether-ether-ketone (PEEK) coatings on Ti6Al4V substrates for blood-contacting implants. The wettability, surface roughness elastic modulus were examined. Blood tests conducted by erythrocytes observation, hemolysis assay clotting...

Face-on oriented show lower adhesion, friction, stronger wear resistance, SAMs. Hierarchical...
The larger friction of the successfully constructed assembly saccharic acid indicates higher potential energy barrier at interface.
Molecular doping has proved to be an efficient technique improve the properties of pristine materials. A better understanding it is quite necessary. For first time, force field parameters transition metal chromium (Cr) doped in 2H-MoS2 molecular dynamics (MD) were developed.
