The authors report the growth of TiO 2 nanowires by heating the Ti/glass template and the fabrication of a TiO 2 nanowire photodetector (PD) by depositing interdigitated contact electrodes. It was also found that the fabricated TiO 2 nanowire PD was visible-blind with a cutoff wavelength around 390 nm. Compared with c…
Substituted poly(o-toluidine) (POT) was synthesis by chemical polymerization method using ammonium persulphate as oxidizing agent. Thin fims of poly(o-toluidine) have been prepared by spin coating method and characterized by (FTIR) spectra and Atomic force microscope (AFM). Current-voltage characteristic of AL/POT/AL…
Water-soluble dendritic ligands based on tris-2-(5-sulfonato salicylaldimine ethyl)amine (5) and DAB-(5-sulfonato salicylaldimine) (6) (DAB = diaminobutane) were synthesized by means of Schiff base condensation and sulfonation reactions. These dendritic ligands were fully characterized by (1)H NMR, (13)C NMR and FT-IR…
Novel, highly-dispersed, carbon-supported nickel catalysts with Ni loading from 6.8 to 20.2 wt% were successfully prepared via in situ self-reduction of hybrid Ni–Al layered double hydroxide/carbon (NiAl-LDH/C) nanocomposite precursors, which were assembled by a separate nucleation and aging process accompanied by the…
A weakly fluorescent nitroolefin functionalized BODIPY 1 was prepared and rapidly reacted with thiols through an unexpected conjugated addition to the azafulvene ring of BODIPY to generate highly fluorescent BODIPYs 4 and 5. This reaction was applied for the highly selective and sensitive detection of Cys in living ce…
Highly flexible, paper-like, free-standing V2O5 and V2O5–polypyrrole (PPy) films were prepared via the vacuum filtration method. The films are soft, lightweight, and mechanically robust. The electrochemical performance of the free-standing pure V2O5 electrode was improved by incorporating conducting polypyrrole. A ben…
Ultrasonication was employed to induce the uniform adsorption of carbon nanotubes (CNTs) onto electrospun polymer nanofiber (EPNF) surfaces. Compared with pristine CNTs, acid treated CNTs became shorter, which facilitated their decoration onto the EPNF surfaces more tightly and densely. Under ultrasonication, CNTs pos…

In this communication, we describe the covalent assembly of gold nanoparticles into core-satellite clusters using the "cream of the crop" Click reaction, namely, azide-alkyne Huisgen 1,3-dipolar cycloaddition. Surface enhanced Raman scattering (SERS), localized surface plasmon resonance (LSPR) spectroscopy, transmissi…
Photoluminescence (PL) and cathodoluminescence (CL) properties of Ln3+ (Ln = Tb, Dy, Eu, Tm, Ce) and Mn2+-activated KCaGd(PO4)2 (KCG) phosphors were investigated. Under UV excitation, KCG:Tb3+, KCG:Dy3+, KCG:Eu3+, KCG:Tm3+, and KCG:Mn2+ samples exhibit the characteristic emission of the activators, respectively. By al…
Oligonucleotide (T30695) modified gold nanoparticles (T30695-Au NPs) have been prepared and employed for quantification of lead ions (Pb(2+)) in blood. The detection of Pb(2+) ions is through the formation of Au-Pb alloys and oligonucleotide-Pb(2+) complexes that catalyze the H(2)O(2)-mediated oxidation of non-fluores…
INTRODUCTION: The recent identification of menstrual blood-derived stem cells (MenSCs) as a unique population of stem cells has created enormous promise for tissue engineering. In this study, after characterization of MenSCs in comparison with bone marrow-derived stem cells (BMSCs), the potential of MenSCs seeded into…
Arsenic pollution in drinking water or surface water has become a worldwide environmental issue and is a serious threat to human health. In this study, Mn–Fe–CO3 layered double hydroxides (LDHs) were prepared by the co-precipitation method, for the removal of As(III) and As(V) from solutions. The physical and chemical…
The inhibitive effect of 4-Aminoantipyrine (4-AAP) on the corrosion of mild steel in 0.5 M H2SO4 solution at 303 – 323 K was studied by weight loss measurement as well as computational techniques. Results obtained showed that 4-aminoantipyrine (4-AAP) is a good inhibitor for the corrosion of mild steel in sulphuric ac…
The recent discovery of iron-based superconductors has evoked enthusiasm for extensive research on these materials because they form the second high-temperature superconductor family after the copper oxide superconductors and impart an expectation for materials with a higher transition temperature ( T c ). It has also…
Magnesium (Mg) and its alloys have increased applications in industry. These applications are getting limited due to Mg corrosion, especially in chloride containing environments, because of its high negative potential. The objective of the present work thus was to report the corrosion of Mg in stagnant solutions of th…
Physicochemical properties of rubber seed oil (RSO) were investigated using standard techniques in order to obtain specific dat a for the oil. The oil was characterized for the following parameters: saponification value (193.61), ester value (191.93), viscosity (10.32 poise), refractive index (1.46), iodine valu e (13…
The synthesis, characterization and application of biologically synthesized nanomaterials are an important aspect in nanotechnology. The present study deals with the synthesis of silver nanoparticles (Ag-NPs) using the aqueous extract of brown seaweed Padina tetrastromatica leaf extract. The complete reduction of silv…
Current compositions of biodegradable aliphatic polyesters experience a number of limitations associated with the difficulty of customizing mechanical, physicochemical, and biological properties for different biomedical applications. In this study, we propose a new class of multiblock copolyesters made using butylene…
We present a new variant of the geometry reconstruction approach for the formulation of atomistic/continuum coupling methods (a/c methods). For many-body nearest-neighbor interactions on the two-dimensional triangular lattice, we show that patch test consistent a/c methods can be constructed for arbitrary interface ge…
