We report a new class of nanocomposite electrodes for the development of high-performance supercapacitors with environmentally friendly ionic liquid electrolytes. Having the high-surface-area activated carbons, carbon nanotubes, and ionic liquids as integrated constituent components, the resultant composites show sign…
New noncentrosymmetric rare-earth metal gallium thioantimonates, Ln(4)GaSbS(9) were synthesized from stoichiometric element mixtures at 950 °C by high-temperature solid-state reactions. These compounds crystallize in orthorhombic space group Aba2 (no.41) with a = 13.799(3)-13.427(5) Å, b = 14.187(3)-13.756(5) Å, c = 1…
Structured porous inorganic materials show high chemical and mechanical stability under an array of physiological conditions. Their hydrophilic character and porous structure can in principle be tailored to control the diffusion rate of an adsorbed or encapsulated drug, gene, or protein. This organized porosity has be…
A novel ultrasensitive multiplexed immunoassay method was developed by combining alkaline phosphatase (ALP)-labeled antibody functionalized gold nanoparticles (ALP-Ab/Au NPs) and enzyme-Au NP catalyzed deposition of silver nanoparticles at a disposable immunosensor array. The immunosensor array was prepared by covalen…
Near their glass transition temperature T(g), supercooled liquids display dramatic changes regarding the dynamics if subject to geometrical restrictions on the scale of 2 to 200 nm. Confinement-induced shifts of T(g) of 25 K have been reported, equivalent to relaxation times that differ by several orders of magnitude…
Electrochemical devices have the potential to pose powerful solutions in addressing rising energy demands and counteracting environmental problems. However, currently, these devices suffer from meager performance due to poor efficiency and durability of the catalysts. These suboptimal characteristics have hampered wid…
An electron donor−acceptor structured π-conjugated organic compound 1 composed of trifluoromethyl-biphenyl and cyano-stilbene-amine was designed and exhibited multi-stimuli-responsive fluorescence switching behaviors. The synthesized solid exhibited piezochromism in that grinding and heating could change the emission…
The ability to generate accurate coarse-grained models from reference fully atomic (or otherwise "first-principles") ones has become an important component in modeling the behavior of complex molecular systems with large length and time scales. We recently proposed a novel coarse-graining approach based upon variation…
The reliable and sensitive detection of cancer-specific biomarkers is important for the diagnosis and treatment of cancer. Hence, detection of these biomarkers has to be reliably and rapidly performed in diverse settings. A limitation of the conventional biomarker-screening method of enzyme-linked immunosorbent assay…
A series of reduced and oxidized Pd/TiO 2 catalysts were prepared and used for catalytic oxidation of formaldehyde (HCHO) at room temperature. The reduced catalysts were much more active than the oxidized ones. Nearly 100% HCHO conversion was achieved over the former while it was less than 18% over the latter. Sodium…
BACKGROUND: Some manufactured nanoparticles are metal-based and have a wide variety of applications in electronic, engineering and medicine. Until now, many studies have described the potential toxicity of NPs on pulmonary target, while little attention has been paid to kidney which is considered to be a secondary tar…
In this work, we present a simple seeded growth approach to obtain gold nanoparticles over a large range of sizes. The method produces particles with uniform spherical shape and narrow size distributions. Using ascorbic acid as a reductant and sodium citrate as stabilizer we utilize biocompatible and easy to exchange…
Intravenously injected nanoparticulate drug carriers provide a wide range of unique opportunities for site-specific targeting of therapeutic agents to many areas within the vasculature and beyond. Pharmacokinetics and biodistribution of these carriers are controlled by a complex array of interrelated core and interfac…
Nanomedicine, the application of nanotechnology to medicine, enabled the development of nanoparticle therapeutic carriers. These drug carriers are passively targeted to tumors through the enhanced permeability and retention effect, so they are ideally suited for the delivery of chemotherapeutics in cancer treatment. I…
In the present study, the dielectric, ferroelectric, and voltage‐tunable characteristics of the Na 0.5 Bi 0.5 TiO 3 –Li 0.45 La 0.52 □ 0.03 TiO 3 homogeneity range were investigated, together with the associated microstructural properties. The results revealed the polarization characteristics of the investigated sampl…
Abstract The kinetics of acrylonitrile polymerization initiated by free radicals formed in situ in a potassium persulfate/ascorbic acid redox system was investigated in an aqueous sulfuric acid medium in the temperature range of 40–70°C. The rate of polymerization and the rate of the disappearance of potassium persulf…
Abstract In the electrochemical elaboration of porous semiconductors and for a certain class of macropores, the pore direction appears to follow the current lines. However, in the presence of a large transverse magnetic field, the current lines at the semiconductor/electrolyte interface exhibit an abrupt change of dir…
Abstract In this study, we report on structural variation of ultrathin of p‐type Porous Silicon (PS) films during the early stage growth process using X‐Ray Reflectometry (XRR). The PS samples were firstly characterized by Fourier Transform Infrared spectroscopy (FTIR) measurements. The homogeneity and surface roughne…
The morphology of an AB diblock copolymer comprising a highly biocompatible poly[2-(methacryloyloxy)ethyl phosphorylcholine] block and a pH-sensitive poly[2-(diisopropylamino)ethyl methacrylate] block (PMPC 30 - b -PDPA 60 ) was analyzed using SAXS and (S)TEM. PMPC 30 - b -PDPA 60 films cast from ethanol solution at r…
An analytical solution for the temperature change and thermal stresses for the circumferential transient loading are obtained using finite Hankel and Fourier transform. Numerical calculations are carried out for a two-layered angle-ply hollow cylinder in the different orientation angles with sudden and periodic temper…
