Single-atom catalyst (SAC) is one of the newest catalysts, and attracts people’s wide attention in cancer therapy based on their characteristics maximum specific catalytic activity high stability. We designed synthesized a Fe-N decorated graphene nanosheet (Fe-N5/GN SAC) with coordination number five. Through enzymology theoretical calculations, Fe-N5/GN SAC has outstanding intrinsic peroxidase...

direct electron transferring of glucose oxidase was investigated   on reduced graphene and graphene oxide templates. the direct electrochemistry   glucose oxidase on   graphene showed a cyclic voltammograms corresponding to the fad/fadh 2   redox couple with an anodic, cathodic and formal potential of -430, -460 and   -445 mv, respectively in 0.1 m phosphate buffer solution and air saturated   ...

Graphene field-effect transistors are recognized as a potential alternative to metal-oxide-semiconductor and can become new element base in the post-silicon epoch. Increasing efficiency of graphene electronic devices simplifying their manufacturing technology important R&D areas. New technical solutions related development proposed paper. A reduced oxide (RGO) film was used conducting chann...

Abstract The continuously increased existence of contaminants such as chemical and biological mainly dye, bacteria, heavy metals ions (HMI) in water bodies has environmental concern due to their hostile effects on living things. Therefore, there is necessity be developed newer materials that skirmishes menace. present works focus the synthesis a novel three-dimensional (3D) polymer-metal–carbon...

graphene-based nanocomposites are newly emerged materials with a wide range of applications such as in supercapacitors electrode. the high conductivity and ability for passing electric current, makes graphene an appropriate new item to be used in cells. electroactive transition metal oxides, owing fast reversible redox pairs, are used to store electrical charge. furthermore, the graphene/nio na...

We developed a WS2 nanosheet based chemiluminescence resonance energy transfer (CRET) platform for sensing biomolecules. This platform exhibits high detection sensitivity and high specificity for target molecules.

This paper represents a new lubricant method which is able to one-stroke drill deep holes with length-to-diameter of 8, on the AISI SUS 304 stainless steel. By adding graphene nanosheet into typical soluble emulsion and then mixing water, nano fluid can be made. The results revealed that using nanofluid provide reduction 4.4-fold drilling torque, thus expand tool life as many 20 times, compared...

graphene, after its first production in 2004 have received lots of attentions from researchers because of its unique properties. high mobility, high sensitivity, high selectivity and high surface area make graphene excellent choice for bio application. one of promising graphene base device that has amazingly high sensitivity is graphene field-effect transistor (gfet). this review selectively su...
