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…
SUMMARY This paper proposes a macroscopic model for ferromagnetic hysteresis that is well‐suited for finite element implementation. The model relies on a consistent thermodynamic formulation. The stored magnetic energy and the dissipated energy are known at all times and not solely after the completion of closed hyste…
This paper reports a non‐catalyzed environmentally friendly method of synthesizing hyperbranched polymethylvinylborosiloxanes (PMVBSs) and their use to improve the thermal stability of normal addition‐curable silicones (ACSs). PMVBSs were synthesized by the direct polycondensation of dimethoxymethylvinylsilane with bo…
We numerically and experimentally demonstrate a tunable electromagnetically induced transparency (EIT)-like spectral response in a self-asymmetric planar metamaterial in microwave region. This EIT-like physical mechanism is characterized by magnetic dipole coupling induced transparency, which is different from classic…
Fluorinated ethylene propylene (FEP) films were made superhydrophobic by Ar + O2 plasma etching process. Field emission scanning electron microscopy and atomic force microscopy studies of the plasma-treated FEP samples detected the presence of uniformly distributed nano-protrusions exhibiting a low surface roughness n…
The crystalline morphology and structure of poly(L-lactide) (PLLA) in a PLLA film–chloroform system were investigated by means of wide angle X-ray diffraction (WAXD), polarized optical microscopy (POM) and atomic force microscopy (AFM). Birefringent and nonbirefringent ring banded supra-structures with radial periodic…
