In this study, a novel tissue engineering scaffold material of electrospun silk fibroin/nano-hydroxyapatite (nHA) biocomposite was prepared by means an effective calcium and phosphate (Ca-P) alternate soaking method. nHA successfully produced on regenerated fibroin nanofiber as substrate within several minutes without any pretreatments. The morphologies both nonmineralized mineralized nanofibers were analyzed using field-emission scanning electron microscopy (FESEM). crystallographic phases...
The NiCo<sub>2</sub>S<sub>4</sub>ultra-nanosheet-decorated 3D porous electrode displayed an excellent electrochemical performance due to its nature, shorter diffusion path length, good adhesive properties and lower interface contact resistance.
Abstract The design and development of an economic highly active non-precious electrocatalyst for methanol electrooxidation is challenging due to expensiveness the precursors as well processes non-ecofriendliness. In this study, a facile preparation core-shell-like NiCo 2 O 4 decorated MWCNTs based on dry synthesis technique was proposed. synthesized /MWCNTs were characterized by infrared spectroscopy, scanning electron microscopy, transmission X-ray diffraction selected area energy...

To meet the requirement for high-ranked positive electrode materials having auspicious pseudocapacitive features potential application in energy storage devices, suitable designs of unique core–shell heterostructures featuring mixed transition metal oxide and layered double hydroxide (LDH) are highly needed have been progressing expeditiously recent years. Herein, 3D hierarchical zinc–nickel–cobalt (ZNCO)@Co–Ni-LDH (LDH-1 LDH-2) nanostructured arrays on Ni foam as a prepared by using facile...
The scrupulous designation of hollow and porous electroactive materials incorporating prolific redox-active polyphase transition-metal oxide decorated with sulfide onto rGO (reduced graphene oxide)-supported conductive substrate has never been an easy task due to the very good coordination affair sulfur toward transition metals. Herein, cost-effective hydrothermal growth followed by a metal–organic framework (MOF)-mediated sulfidation approach is employed achieve burl-like Ni–Co–S...
Abstract Nanosecond laser patterning of Copper Metal–Organic Framework (Cu‐MOF) coated substrates is performed to fabricate non‐enzymatic glucose sensing electrodes. The Cu‐MOF glass substrate with a cover subjected process; the amount MOF, fluence, and scan speeds mainly influenced process. electrodes are fabricated on covered varying electrical conductivity due high energy absorptivity. patterned consist graphitic carbon incorporated nano‐Cu show stable substrates. chemically active in Fe...
In-situ polymerization is an effective method for integrating co-catalysts homogeneously into the polymer matrix. Polyacrylonitrile (PAN)-derived highly graphitized carbon a state-of-the-art material with diverse applications, including materials energy storage devices, electrocatalysis, sensing, adsorption, and making structural composites of various technologies. Such can be effectively obtained through in-situ polymerization. The addition external catalysts during not only enhances rate...
Water-soluble poly(3-thiophene acetic acid) (P3TAA) and its copolymers with 3-n-methylthiophene or 3-n-octadecylthiophene were synthesized. The solution properties of these water-soluble polythiophene carboxylic acids studied by potentiometric titration, viscosity measurements, UV−visible spectroscopy. We have found that the Henderson−Hasselbach plot titration curve showed an inflection slope around pH = 5−6. reduced electronic spectra P3TAA aqueous also abrupt change at this region. These...
Well-defined amphiphilic telechelics incorporating polyhedral oligosilsesquioxane (POSS) were synthesized by direct urethane linkage between the diol end groups of poly(ethylene glycol) (PEG) homopolymers and monoisocyanate group POSS macromers. The hydrophobicity was varied using a series PEG increasing molecular weight, resulting in control over architecture hydrophilic/hydrophobic balance. characterized 1H NMR, FT-IR, GPC, DSC, TGA, showed relatively narrow unimodal weight distribution...
