We have demonstrated that by coating with a thin dielectric layer of tetrahedral amorphous carbon (ta-C), biocompatible and optical transparent material in the visible range, Ag nanoparticle-based substrate becomes extremely suitable for surface-enhanced Raman spectroscopy (SERS). Our measurements show 10 Å or thicker ta-C efficient to protect oxygen-free air prevent ionizing aqueous solutions. Furthermore, nanoparticles coated film shows higher enhancement signals than uncoated substrate....

Abstract The research of organic materials thrives for lithium‐ion and sodium‐ion batteries but lacks aqueous Zn 2+ batteries. Herein, we prepared 1,4,5,8‐naphthalene diimide (NTCDI), which is derived from 1,4,5,8‐naphthalenetetracarboxylic dianhydride, through nitrogen substitution with the assistance ammonia solution. NTCDI first applied in batteries, can give a high reversible capacity 240 mAh g −1 at 0.1 A . electrochemical kinetics analysis indicates that diffusion‐control process...
NiCo2O4@reduced graphene oxide (rGO)/nickel foam (NF) composites were prepared via a hydrothermal method followed by annealing assisted hexadecyl trimethyl ammonium bromide (CTAB). NiCo2O4@rGO/NF nanoneedle arrays grew directly on Ni without using binder. The effect of (GO) concentration the electrochemical properties composite was studied. When GO 5 mg L-1, as-prepared reaches highest specific capacitance 1644 F g-1 at current density 1 A g-1. Even 15 g-1, is still 1167 and retention rate...
A mild wet chemical synthesis route, hydrothermal treatment–photodeposition, was developed to obtain a series of heterostructured metallic silver/bismuth niobate (Ag/Bi5Nb3O15) hybrid materials with single-crystalline orthorhombic layered structure and photoresponse in both the UV visible light region. As novel alternative photocatalyst TiO2, photocatalytic activity as-prepared Ag/Bi5Nb3O15 evaluated by degradation an aqueous tetrabromobisphenol (TBBPA, member thebrominated flame retardant...
Plate- and octahedron-like Pt/Bi5Nb3O15 heterostructures are controllably prepared by a hydrothermal treatment method combined with photodeposition in the presence of different surfactants, i.e., cetyltrimethylammonium bromide (CTAB) polyvinylpyrrolidone (PVP). The composition, structure, morphology, optical absorption properties, textural properties as-prepared well-characterized, their simulated sunlight visible-light photocatalytic activity is evaluated degradation two typical organic...
Orthorhombic vanadium pentoxide (V2O5) nanowires with uniform morphology were successfully fabricated via a facile hydrothermal process. The effect of disodium citrate dosage on the crystallinity, and electrochemical properties products was analyzed. Experimental results indicate that orthorhombic V2O5 high crystallinity diameter about 20 nm can be obtained at 180 °C for 24 h when is 0.236 g. Furthermore, prepared demonstrate specific capacitance 528.2 F g-1 0.5 A retention 85% after 1000...
Copper diffusion barrier performance of titanium nitride films was enhanced by formation a ternary Ti-Si-N layer. The TiSiN are prepared chemical vapor deposition (CVD) using metallorganic precursor (MOCVD-TiN) thermal decomposition tetrakis(dimethylamino)titanium (TDMAT). is followed plasma treatment with gas mixture nitrogen and hydrogen in order to reduce the resistivity films. Finally, situ exposed silane. This leads Si-N bond layer film. process delivers film conformal step coverage low...
