New magnetic hydroxyapatite-based nanomaterials as bone-specific systems for controlled drug delivery have been synthesized. The synthesized hydroxyapatite, HA, decorated with magnetite nanoparticles by a deposition method (HA/Fe3O4) and the nanocomposite system obtained using magnetic multi-walled carbon nanotubes (H…
Gold nanoparticles have garnered interest as both radiosensitzers and computed tomography (CT) contrast agents. However, the extremely high concentrations of gold required to generate CT contrast is far beyond that needed for meaningful radiosensitization, which limits their use as combined therapeutic-diagnostic (the…
Modified nucleosides are important biomarkers of cancers. For their analysis, boronate adsorbents were widely used to selectively capture them from urine, but often suffered from serious secondary hydrophobic interaction and harsh alkaline extraction condition. In this work, the hybrid titania-zirconia nanoparticles c…
The ability to shape-shift in response to a stimulus increases an organism's survivability in nature. Similarly, man-made dynamic and responsive "smart" microtechnology is crucial for the advancement of human technology. Here, 10-30 μm shape-changing 3D BSA protein hydrogel microstructures are fabricated with dynamic,…
Formic acid adsorption and photooxidation on TiO 2 nanoparticle surfaces at 296 K have been investigated using transmission FTIR spectroscopy. In particular, the role of adsorbed water in surface coordination, adsorption kinetics, and photoproduct formation is examined. Gas-phase formic acid adsorbs on the surface at…
INTRODUCTION: Recurrence or early metastasis remains the predominant cause of mortality in patients with estrogen receptor positive (ER+) mammary carcinoma (MC). However, the molecular mechanisms underlying the initial progression of ER+ MC to metastasis remains poorly understood. Trefoil factor 3 (TFF3) is an estroge…
BACKGROUND: Inhalation of chemotherapeutic drugs directly into the lungs augments the drug exposure to lung cancers. The inhalation of free drugs however results in over exposure and causes severe adverse effect to normal cells. In the present study, epidermal growth factor (EGF)-modified gelatin nanoparticles (EGNP)…
Many common density functional theory methods used in the study of adsorption on metals lack dispersion contributions. Formulations like the random phase approximations would mitigate this error, but they are computationally too expensive. Therefore, semiempiric treatments based on dispersion coefficients turn out to…
Dietary antioxidants as health promoters for human beings have attracted much attention and triggered tremendous efforts in evaluation of the antioxidant capacity. Unfortunately, no versatile detection system has been designed to date. Due to the possible synergistic effect among antioxidant components in a diversifie…
Accurate static electromagnetic characteristics are essential basic data in the modeling of switched reluctance machine (SRM) for performance analysis and advanced control purposes. Because of the doubly salient structure and deep magnetic saturation, the electromagnetic characteristics of SRM have highly nonlinear re…
The ability to control the spin-transport properties of a molecule bridging conducting electrodes is of paramount importance to molecular spintronics. Quantum interference can play an important role in allowing or forbidding electrons from passing through a system. In this work, the spin-transport properties of a poly…
Cu2ZnSnS4 (CZTS) holds great promises as an absorber material for sustainable and low cost thin film solar cells. Kesterite and wurtzite are two common phases of CZTS. Until now, the synthesis and the growth of both phases are not clearly understood. In this work, kesterite CZTS nanoparticles, wurtzite CZTS nanopartic…
Assessment of reaction substrate scope is often a qualitative endeavor that provides general indications of substrate sensitivity to a measured reaction outcome. Unfortunately, this field standard typically falls short of enabling the quantitative prediction of new substrates' performance. The disconnection between a…
Fully bio‐based composites composed of polybenzoxazine resins obtained from renewable natural resources (such as cardanol, furfurylamine, and stearylamine) and bio‐fiber such as jute fiber were prepared. The purity of the isolated cardanol was determined by Gas Chromatography. The structure of cardanol and its benzoxa…
Magnesite is the most desirable phase within the magnesium carbonate family for carbon storage for a number of reasons: magnesium efficiency, omission of additional crystal waters and thermodynamic stability. For large-scale carbonation to be a viable industrial process, magnesite precipitation must be made to occur r…
From a one-pot nickel-mediated Yamamoto-type coupling reaction of m-dibromobenzene, five congeners of [n]cyclo-meta-phenylenes were synthesized and fully characterized. The [n]cyclo-meta-phenylenes possessed a commonly shared arylene unit and intermolecular contacts but varied in packing structures in the crystalline…
Fe 2 O 3 is widely considered a promising material for converting solar energy through oxidizing water. We model the mechanism of water oxidation on Fe 2 O 3 (0001) surface in the presence of defects that have been recently modulated experimentally. We use a density functional theory type method (DFT + U) on several s…
Here we report on the synthesis of novel dendritic Pt3Cu triangular pyramid caps via a solvothermal coreduction method. These caps had three-dimensional caved structures with ultrathin branches, as evidenced by high-resolution transmission electron microscopy (HRTEM) and HAADF-STEM characterization. Tuning the reducti…
Lithium-neutralized graphene oxide (GO-Li) was spin coated between the photoactive layer and the metal oxide electron-transporting layer (ETL) as an additional interlayer in organic photovoltaic devices. The introduction of GO-Li leads to a superior interface between the ETL and the photoactive layer. Combined with th…
CuIn${}_{1-x}$Ga${}_{x}$Se${}_{2}$ (CIGS) is an important photovoltaic material, but variations in composition and nanoscale textures that form naturally during processing thwart accurate modeling. The authors develop a general formalism to simulate the charge carrier collection in complex multilayered systems, permit…
