Trace detection of polycyclic aromatic hydrocarbons (PAHs) by surface-enhanced Raman scattering (SERS) on a metal sandwich substrate bridged 1,10-decanedithiolis is reported in this work. The bowl-shaped silver cavity (BSSC) thin film bottom layer was prepared electrodeposition using closely packed monolayer 500 nm diameter polystyrene spheres as template. as-prepared array has proven to be SERS-active with excellent performance and reproducibility when p-aminothiophenol (PATP) the probe...
In this study, Co3O4 with different morphologies (leaf, sheet, and cube) are successfully synthesized by a facile hydrothermal method followed calcination treatment. Representative samples morphological structures compared evaluated as anode materials in lithium-ion batteries. Relative to the Co3O4-sheet Co3O4-cube samples, Co3O4-leaf exhibit excellent electrochemical performance high storage capacity (1245 mA h g−1 after 40 cycles at 0.1 C) superior rate capability (0.1, 0.2, 0.5, 1, 2 C...
A new kind of metal oxide nanoparticle coated with a uniform layer N-doped carbon (e.g., Fe3O4@CNy, CoOx@CNy) was prepared readily in one-step. The nanoparticles show high and stable lithium storage ability for lithium-ion battery applications.
Tin dioxide (SnO2) attracts considerable attention as an anode material due to its high theoretical capacity compared with graphite. However, the practical use of a SnO2 is significantly hampered by large volume changes during lithium insertion and extraction processes, which leads poor cyclic performance. To overcome this problem, simple efficient method was employed fabricate SnO2-based nanocomposites controlled titanium nitride (TiN) modification. The as-prepared samples were...
Surface nitridation of the Li4Ti5O12 particles was carried out by thermal treatment with urea as nitrogen source in a controllable manner. The titanium nitride (TiN) formed well-dispersed zones on surface particles, depending coverage nitride. TiN led to great improvement conductivity oxide. extent exhibited large effect electrochemical behaviors Li4Ti5O12/TiN composite (prepared using 6 % urea) providing best initial capacity and rate capability. Thus, performance can be achieved optimizing...
A method for the highly sensitive determination of 2-, 3- and 4-nitrophenols was developed using reverse-phase high-performance liquid chromatography (RP-HPLC) with a UV photodiode array detector. Using column 40% aqueous acetonitrile as an eluent (i.e. isocratic elution), integrated peak area detector output linear up to 300 mg/L detection limit 150 µg/L. The sensitivity this improved by pretreating sample solutions solvent extraction procedure that makes use high partition coefficient...
Herein, a transparent and reproducible substrate, fabricated using polydimethylsiloxane (PDMS) laminated with self-assembled Ag nanoparticles (Ag NPs), was employed as universal surface-enhanced Raman scattering (SERS) substrate for the detection of targets various matrices. The NPs were assembled in two-dimensional manner via self-assembly technique. Due to electrostatic interaction between NPs, reproducibility assembly ensured by fixed density at saturated states. pattern plasmon resonance...
Thermoplastic starch/latex polymer composites were prepared using styrene–butadiene latex and heat-treated cornstarch. The in a compression mold at 130°C, with 20% starch content. An amylose-free cornstarch, waxy maize, was used for this research, the heat treatment range from ambient temperature to 170°C. (HTS) characterized by optical microscopy, dynamic light scattering, size exclusion chromatography. mechanical analysis (stress–strain) scanning electron microscopy. tests of revealed...
