A novel “three‐step approach” of methanesulfonic acid/γ‐aminopropyl triethoxy silane/GlycidylEthyl polyhedral oligomeric silsesquioxane (MSA/KH550/POSS) was proposed to functionalize the surface of high modulus poly ( p‐ phenylene‐2,6‐benzobisoxazole) (HMPBO) fibers. Results indicated that GlycidylEthyl POSS was succe…
A centrosymmetric polymer precursor, 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)butan-1-amine (TPBA), was synthesized via a Knorr–Paal reaction and its copolymer with EDOT was electrochemically synthesized and characterized. While P(TPBA) has only two colors in its oxidized and neutral states, its copolymer with EDOT has…
We explore multiple energy losses and gains undergone by swift electrons interacting with resonant evanescent light fields. We predict remarkably high gain probabilities in the range of a percentage when the electrons are passing near a resonant plasmonic structure under continuous-wave illumination conditions with mo…
The creation of engineered intestinal tissue has recently stimulated new endeavors with the ultimate goal of intestinal replacement for massive resections of bowel. In this context, we investigated the effect of hyaluronic acid (HA) on the physicochemical characteristics of gelatin-collagen scaffolds and its cytocompa…
Polyhydroxyalkanoate (PHA) production via mixed microbial cultures (MMCs) can potentially decrease process operational costs as compared to conventional pure culture techniques. However, the volumetric productivity of PHA by MMCs must be augmented to increase its cost competitiveness. For this purpose, a three‐stage b…
Room-temperature ferromagnetism was observed in un-doped ZrO2 thin films prepared by pulsed electron beam deposition on silicon substrates. In the obtained films, monoclinic and tetragonal phases were both stabilized, with a ratio depending on the oxygen partial pressure during deposition. The ferromagnetism was posit…
A system of novel nanoparticles of star-shaped cholic acid-core polylactide-d-α-tocopheryl polyethylene glycol 1000 succinate (CA-PLA-TPGS) block copolymer was developed for paclitaxel delivery for breast cancer treatment, which demonstrated superior in vitro and in vivo performance in comparison with paclitaxel-loade…
Sub-micrometer carriers (nanocarriers; NCs) enhance efficacy of drugs by improving solubility, stability, circulation time, targeting, and release. Additionally, traversing cellular barriers in the body is crucial for both oral delivery of therapeutic NCs into the circulation and transport from the blood into tissues,…
A core–shell structured nanocomposite, with hexagonal Mg–Al mixed oxide nanoplates derived from LDHs as the inner core and Al-containing mesoporous silica as the outer shell, was prepared using an inorganic, low cost and simple route. The mesoporous silica shell was not only capable of protecting the MgAl-LDO core, bu…
Thixotropic hydrogelators have great potential in biomedical and biotechnological applications. In this study, we report new hydrogelators and their behavior during gel-sol-gel transitions. In particular, cyclo(L-O-hydroxyhexylaspartyl-L-phenylalanyl), which was synthesized with 1,6-hexanediol, formed a thermally/isot…
INTRODUCTION: The application of mesenchymal stem cells (MSCs) in treating rheumatoid arthritis (RA) has been made possible by the immunosuppressive and differentiation abilities of these cells. A non-invasive means of assessing cell integration and bio-distribution is fundamental in evaluating the risks and success o…
Bovine serum albumin (BSA) protected nanoclusters (Au and Ag) represent a group of nanomaterials that holds great promise in biophysical applications due to their unique fluorescence properties and lack of toxicity. These metal nanoclusters have utility in a variety of disciplines including catalysis, biosensing, phot…
IrO 2 has been investigated as alternative rutile-type catalyst to RuO 2 for gas-phase HCl oxidation. The HCl conversion level over IrO 2 at 723 K was comparable to that of RuO 2 at ca. 170 K lower temperature, in line with the higher computed energy barrier for chlorine evolution over the former oxide. Similarly to R…
Graphene shows great promise as a transparent conductive electrode to replace conventional indium tin oxide (ITO) for optoelectronic applications. However, the wide applications of graphene in fields such as organic light emitting diodes (OLEDs) are restricted by the difficulty in obtaining a clean and flat graphene s…
We present here a novel camptothecin (CPT) prodrug based on polyethylene glycol monomethyl ether-block-poly(2-methacryl ester hydroxyethyl disulfide-graft-CPT) (MPEG-SS-PCPT). It formed biocompatible nanoparticles (NPs) with diameters of approximately 122 nm with a CPT loading content as high as approximately 25 wt% i…
We analytically and numerically consider the hydrodynamic and thermal transport behavior of fully developed laminar flow through a superhydrophobic (SH) parallel-plate channel. Hydrodynamic slip length, thermal slip length and heat flux are prescribed at each surface. We first develop a general expression for the Nuss…
High-density La-doped ZnO nanowires (NWs) were grown hydrothermally on flexible polyimide substrate. The length and diameter of the NWs were around 860 nm and 80-160 nm, respectively. All XRD peaks of the La-doped sample shift to a larger angle. The strong PL peak of the La-doped sample is 380 nm, which is close to th…
A highly tough and transparent film material was prepared from synthetic saponite (SPN) nanoplatelets of low aspect ratios and nanofibrillar cellulose. The nanofibrillar cellulose was chemically modified by topological surface oxidation using 2,2,6,6-tetramethylpiperidinyl-1-oxyl (TEMPO) as a catalyst. Both synthetic…
Enhancing the deposition and permeation of 5-fluorouracil across human epidermis assisted by appropriately charged and well-defined peptide dendrimers was investigated. Peptide dendrimers with arginine as the terminal amino acid and having a range of terminal positive charges (4(+), 8(+) and 16(+)) were synthesized by…
Protein based nanoparticles are functionally efficient for delivery of biomolecules and can be eliminated from the body due to their biodegradable nature.
