Layer-by-Layer (LbL) approach was applied for the encapsulation of antileishmanial drugs viz. chalcones (3-mB-4′-HC and 3-DC-4′-HC) to study their release properties at pH 7.4 from a polyelectrolyte self assembled multilayer thin film. The LbL self assembly was achieved by alternate adsorption of oppositely charged po…
The glasses of compositions x Fe 2 O 3⋅ (40 - x) Bi 2 O 3⋅60 B 2 O 3⋅2 V 2 O 5 have been prepared by the standard melt-quenching technique. Amorphous nature of these samples is ascertained by XRD patterns. The presence of BO 3 and BO 4 units is identified by IR spectra of glass samples. The absorption edge (λ cut-off…
Traditional TiO2 based photodetectors (PDs) suffer from high dark resistance, which increases loss of photoexcited charge carriers. Here, we report a new and simple way to improve the performance of PDs based on double-walled carbon nanotube (DWCNT)/TiO2 nanotube heterojunctions. Highly ordered TiO2 nanotube arrays we…
In this communication, Co/Cu substituted Ni-Zn ferrites processed through sol-gel synthesis using polyethylene glycol (PEG) as a chelating agent are studied, intending to aid in understanding and choosing the optimum ferrite material for high frequency applications. Lattice constant and average crystallite size have b…
The morphology distribution of a model polymer blend, polystyrene (PS)/polyethylene (PE), molded by multimelt multi‐injection molding (MMMIM) process was studied by scanning electronic microscopy and polarizing light microscopy. An unusual double skin/core morphology was observed. The minor phase, PS, showed highly de…
The use of self-assembled monolayers (SAMs) as a polymer-free platform to deliver an antiproliferative drug, paclitaxel (PAT), from a stent material cobalt-chromium (CoCr) alloy has been previously demonstrated. In this study, the interaction of human aortic endothelial cells (ECs) and human aortic smooth muscle cells…
The mixing precipitation of CaCO3 in natural waters was theoretically studied by the methods of chemical equilibrium calculation. Results show that mixing precipitation of CaCO3 can be produced by mixing between two unsaturated water samples with respect to CaCO3, two oversaturated water samples, an unsaturated water…
The aim of this study is to identify a plasticizer that is effective in the suppression of the autohemolysis of the stored blood and can be used to replace di(2-ethylhexyl) phthalate (DEHP) in blood containers. The results of hemolysis test using mannitol-adenine-phosphate/red cell concentrates (MAP/RCC) spiked with p…
A high-output-voltage micro-thermoelectric generator (µTEG) has been developed by fabricating thermocouples having a high aspect ratio (HAR) with a high integration density. They have been made by a novel and simple fabrication method, in which thermoelectric nanopowders are filled in a photosensitive glass mold by us…
We present the results of studying electronic, elastic, vibrational, and thermodynamic properties of type-VIII clathrates Ba8Ga16Sn30 Ba8Al16Sn30 calculated from a first-principles approach. The calculations utilize the generalized gradient approximation to density functional theory. The results indicate that the Ba8G…
To improve the limit of detection in a nanoplasmonic sensor system, the optical performance of the metal nanostructures should be optimized according to the best spectral window of the measurement instrument. We propose that the spectral window from 1460 to 1610 nm can potentially provide ultrahigh instrumental resolu…
Graphene grown directly on Co3O4(111)/Co(0001) by molecular beam epitaxy exhibits extrinsic p-type doping, as demonstrated by photoemission and conductivity measurements. Trilayer heterostructures of graphene/Co3O4(111)/Co(0001) reveal an unconventional magneto-optical Kerr hysteresis with vanishing remanence for temp…
Measurements of the emission linewidth of single nanocrystals are usually limited by spectral diffusion. At cryogenic temperatures, the origin of this instability was revealed to be photo-induced, suggesting that the spectral peak position may be stable in the limit of vanishing optical excitation. Here we test this s…
In this paper, europium polyoxometalate (Na9EuW10O36·32H2O, abbreviated as POM) is encapsulated into the surfactant dodecyl(11-(methacryloyloxy)undecyl) dimethylammonium bromide (DMDA) to form surfactant-encapsulated polyoxometalate (SEP). Methacrylic group-modified ZnO nanoparticles (designated ZnO-MAA) are also prep…
The drug delivery admissibility of nanomaterials such as carbon nanotubes and their uncertain interactions with live tissues and organs have sparked ongoing research efforts. To boost the selective diffusivity of single walled carbon nanotubes (SWCNTs), surface functionalization was adopted in several experimental att…
ABSTRACT Poly(decamethylene terephthalamide) PA10T with different relative viscosities (RV) were successfully produced by the reaction of 1,10‐decanediamine and terephthalic acid through molecular weight regulator benzoic acid (BA). RV was shown to be decreased linearly with increasing BA concentrations and detailed s…
We describe a synchronous reduction and assembly procedure to directly produce large-area reduced graphene oxide (rGO) films sandwiched by a high density of metal nanoparticles (silver and copper). Further, by using the sandwiched metal NPs as sources, networks consisting of AgTCNQ and CuTCNQ nanowires were determinis…
This work evaluates the role of the surface properties and shape of clay type on the morphology, thermal, and thermo-mechanical properties of the polystyrene (PS)/clay nanocomposites prepared via free-radical emulsion polymerization. Attapulgite clay (ATT) with a needle-like morphology and montmorillonite clay (MMT) w…
We calculated the adsorption of SO4 on h-BN and Pd on SO4 adsorbed on h-BN by using first-principles calculations based on density-functional theory. Six stable configurations were found for SO4/h-BN, in which three O atoms of the SO4 molecule bond to the h-BN surface. The adsorption energy of SO4 to h-BN is 1.46 eV.…
Multifunctional nanoparticles show great potential in the biomedical field and may help the diagnosis and therapy of diseases. Superparamagnetic nanoparticles are especially attractive because of their ability to dissipate thermal energy in an alternating magnetic field. Furthermore, plasmonic nanoparticles can be eff…
