Sheet-assembled hollow CuSe nanocubes are fabricated by a facile template-directed selenation method and exhibit record rate capability among the chalcogenide compounds reported so far.
Constructing multiheteroatom coordination structure in carbonaceous substrates demonstrates an effective method to accelerate the oxygen reduction reaction (ORR) of supported single-atom catalyst. Herein, novel etching route assisted by potassium thiocyanate (KCNS) is developed convert metal-organic framework 2D defect-rich porous N,S-co-doped carbon nanosheets for anchoring atomically dispersed iron sites as high-performance ORR catalysts (Fe-SACs). The well-designed KCNS-assisted can...
This study presents a novel and facile strategy to fabricate hydrophilic poly(vinylidene fluoride) (PVDF) electrolyte film with enhanced inner channels for high-performance cost-effective ion-exchange polymer metal composite (IPMC) actuator. The resultant PVDF is composed of hierarchical micro/nanoscale structures: well-defined grains diameter ∼20 μm much finer particles ∼390 nm, producing three-dimensional interconnected, facilitate ion migration IPMC. Interestingly, the matrix has high...
Using body heat for instance, thermoelectric generators have promising applications driving wearable electronics continuously but remain a challenge in terms of recoverable flexibility, as known highly-performing thermoelectrics are usually inorganics showing rigidity. It is conceptualized this work large elastic strain ensuring both largely-curved bending and full recoverability performance after enormous bendings. This leads the current to focus on microstructure engineering approach...
A new non-enzymatic glucose sensor is demonstrated successfully, based on three-dimensional (3D) hierarchical Co3O4 nanobooks (Co3O4 NBs). The 3D NBs are assembled with porous and high crystalline 2D nanosheets. electrochemical measurements reveal that the device exhibits outstanding performance for detection, achieving a maximal sensitivity of 1068.85 μA mM−1 cm−2 R 2 0.9836, low detection limit 7.94 μM signal-to-noise 3 wide linear range up to 6 mM. results demonstrate can respond swiftly...

Both used as...
Cold rolling emulsion contains a variety of functional additives, which often exhibit complex interactions with each other. Sodium alkane sulfonate (SAS) is common corrosion inhibitor used in cold emulsions for temporary rust prevention. In this study, it was found that SAS would deteriorate the tribological properties emulsion. Emulsions containing and different friction modifiers were prepared. Tribology tests carried out on four-ball wear tester. White light interferometer to investigate...

Abstract Si nanowires were grown on Si(111) substrates, and the shape modification of was demonstrated. With Au catalyst, highly symmetric faceted silicide solid particle in Au‐Si eutectic solution formed top nanowires, catalyst defined nanowire. Namely, VLS growth mechanism followed by VSS mechanism, modified shaped nanowire during growth.
