A novel graphene-copper nanoparticle composite was prepared by the in situ chemical reduction of a mixture containing graphene oxide and copper(II) ions using potassium borohydride as reductant. It mixed with paraffin oil packed into one end fused capillary to fabricate microdisc electrodes for sensing carbohydrates. The morphology structure were investigated scanning electron microscopy, X-ray diffraction, Fourier transform-infrared spectroscopy. results indicated that copper nanoparticles...
Poly(methyl methacrylate) (PMMA) is particularly useful for microfluidic chips with the features of low price, excellent optic transparency, attractive mechanical and chemical properties, ease fabrication modification, biocompatibility, etc. During past decade, significant progress in PMMA has occurred. This review, which contains 120 references, summarizes recent advances key strategies fabrication, application chips. It expected that microchips should find a wide range applications will...
In this report, trypsin was immobilized in the layer-by-layer (LBL) coating of graphene oxide (GO) and chitosan on a piece glass fiber to fabricate microchip bioreactor for efficient proteolysis. LBL deposition driven by electrostatic forces easily took place surface fiber, providing mild environmental conditions so that denaturation autolysis minimized. Prior use, prepared trypsin-immobilized inserted into channel form core-changeable bioreactor. The novel GO-based can be regenerated...
In this report, infrared (IR)-assisted on-plate proteolysis has been developed for rapid peptide mapping. Protein solutions containing trypsin were allowed to digest directly on the spots of matrix-assisted laser desorption/ionization (MALDI) plates under IR radiation. The feasibility and performance novel approach investigated by digestion bovine serum albumin (BSA) cytochrome c (Cyt-c). It was demonstrated that radiation substantially enhanced efficiency time significantly reduced 5 min....
Abstract In this report, infrared (IR) radiation was employed to enhance the efficiency of tryptic proteolysis for peptide mapping. Protein solutions containing trypsin in sealed transparent Eppendorf tubes were allowed digest under an IR lamp at 37ºC. The feasibility and performance novel approach demonstrated by digestion BSA myoglobin (MYO) time significantly reduced 5 min. obtained digests identified MALDI‐TOF MS with sequence coverages 69% (BSA) 90% that much better than those...
Abstract A new approach based on far infrared‐assisted in situ reduction was developed for the facile one‐step preparation of graphene–nickel nanoparticle hybrid by refluxing a mixture solution containing graphene oxide, nickel(II) sulfate, and hydrazine over an far‐infrared heater. The time as short 20 min. structure material investigated transmission electron microscopy, scanning X‐ray diffraction, energy dispersive spectroscopy, vibrating sample magnetometery, Fourier transform infrared...
Abstract This report describes the fabrication and application of a novel graphene/poly(urea‐formaldehyde) composite modified electrode as sensitive amperometric detector CE. The was fabricated on basis in situ polycondensation mixture graphenes urea–formaldehyde prepolymers surface platinum disc electrode.

Aqueous batteries, such as aqueous zinc-ion batteries (AZIB), have garnered significant attention because of their advantages in intrinsic safety, low cost, and eco-friendliness. However, electrolytes tend to freeze at temperatures, which limits potential industrial applications. Thus, one the core challenges electrolyte design is optimizing formula prevent freezing while maintaining good ion conductivity. experimental trial-and-error approach inefficient for this purpose, existing...

Silicate is an important rock-forming mineral. In this work, a method called “sulfuric acid curing” was proposed, aiming to extract rare earth element scandium from silicates. Sulfuric curing refers the addition of concentrated sulfuric heated silicates at 60–300 °C, and subsequently water leaching treated 30–75 °C. The effects dosage, time, temperature, pulp density, temperature stirring speed on were investigated. Under condition dosage with 0.75 times theoretical amount, time 15 h, 200...
