Despite the progress made thus far in the generation of small-diameter vascular grafts, cell sourcing still remains a problem. Human embryonic stem cells (hESCs) present an exciting new cell source for the regeneration applications due to their high proliferative and differentiation capabilities. In this study, the fe…
Polylactic acid (PLA)/kenaf bast fiber (KF) composites were prepared with different amounts (0 to 40 wt%) of ethylene acrylate copolymer impact modifier (IM). With increasing IM content, the impact strength and elongation at break of the composites improved but an opposite trend was observed for the tensile strength a…
Carbon nanotubes (CNTs) are mixed into SBR/NR and SBR/IR blends using a wet mixing process. The phase specific localization of CNTs in rubber blends is predicted theoretically using surface energy data of blend components and determined experimentally by means of the wetting concept . Almost all CNTs are found to be l…
For improvement of the conversion efficiency of solar cells, it is important to make effective use of near-infrared light, which accounts for about 40% of sunlight energy. Although solar cells based on quantum dots (QDs) such as PbS have been studied for the use of near-infrared light, their photoabsorption is not nec…
Gold nanoparticles, particularly with the particle size of 2–5 nm, have attracted increasing research attention during the past decades due to their surprisingly high activity in CO and volatile organic compounds (VOCs) oxidation at low temperatures. In particular, CO oxidation below room temperature has been extensiv…
Our present work deals with the hydrothermal synthesis of Platelet β Co(OH) 2 using cobalt(II) acetate as the metal precursor and ammonia solution as the hydrolyzing agent. Electrochemical capacitive performance was studied through cyclic voltammetry (CV), galvanostatic charge discharge (CCD), and electrochemical impe…
Recently discovered (CaFe${}_{1\ensuremath{-}x}$Pt${}_{x}$As)${}_{10}$Pt${}_{3}$As${}_{8}$ and (CaFeAs)${}_{10}$Pt${}_{4\ensuremath{-}y}$As${}_{8}$ superconductors are very similar materials having the same elemental composition and structurally similar superconducting FeAs slabs. Yet the maximal critical temperature…
To solve biostability and organ distribution problems in polymer-coated liposomes, this study developed tumor–extracellular matrix pH-induced targeting polymer–liposome complexes (ECM-targeting liposomes) that are highly stable in a protein-rich environment and can trigger targeting ability in tumor ECM environment. E…
Zinc oxysulfide nanocrystals with zinc blende phase are synthesized through a wet-chemical method. An affirmation of the crystal structure, elemental homogeneity and phase transformation is obtained by X-ray diffraction and authenticated by electron micrographic studies. Theoretical observations have strongly supporte…
We explore the chiral transmission of electrons across graphene heterojunctions for electronic switching using gate geometry alone. A sequence of gates is used to collimate and orthogonalize the chiral transmission lobes across multiple junctions, resulting in negligible overall current. The resistance of the device i…
To tune the toughness of PLA, a novel pathway to chemically modify PLA via reactive extrusion in the presence of “reactive” PEG derivatives is proposed. PEG methyl ether methacrylate (MAPEG) and PEG methyl ether acrylate (AcrylPEG) are melt‐mixed and extruded with PLA in the presence of 2,5‐dimethyl‐2,5‐di( tert‐ buty…
Lichtspiele: Ein organisches Molekül mit Pyren- und Rhodamin-B-Chromophoren, die über eine Peptidbrücke verbunden sind (siehe Struktur), bildet ein mechanochromes Material, dessen Fluoreszenzfarbe durch mechanisches Zermahlen von Blau über Blaugrün zu Rötlich geschaltet werden kann. Die beobachtete Dreifarbenschaltung…
The objective of this study was to prepare chitosan and starch composite films by the addition of 0–3 wt% graphene nanosheets. The film's tensile strength (TS), tensile modulus (TM), elongation at break ( E ), moisture uptake (Mu), and water vapor transmission rate (WVTR) were investigated. The surface morphology of t…
Surface-piercing vegetation often captures particles that flow on the water surface, where surface tension forces contribute to capture. Yet the physics of capillary capture in flow has not been addressed. Here we model the capture of floating particles by surface-piercing collectors at moderately low Reynolds numbers…
A new NH 3 -reduction method was developed for the preparation of Ni–Ce 0.12 Zr 0.88 O 2 catalysts with different Ni loadings (5, 10, and 15 wt %). The reduction of the catalysts was performed in a tube furnace with NH 3 or H 2 . The catalysts were characterized using Brunauer–Emmett–Teller, inductively coupled plasma…
Glass fiber-reinforced epoxy resin (GFRE) composites filled with aluminum nitride (AlN) powder were fabricated, and their thermal and electrical properties were investigated. It is observed that with the increasing percentage of AlN particles, there is a significant enhancement in thermal conductivity and micro-hardne…
ABSTRACT The effect of peroxide on the thermal and crystallization properties of high‐density polyethylene (HDPE) and HDPE/polypropylene (PP) blends has been investigated using differential scanning calorimetry and X‐ray diffraction techniques (XRD). Gel permeation chromatography (GPC) was also employed to study the m…
DNA hybridization was electrically detected by graphene field-effect transistors. Probe DNA was modified on the graphene channel by a pyrene-based linker material. The transfer characteristic was shifted by the negative charges on the probe DNA, and the drain current was changed by the full-complementary DNA while no…
An efficient phototriggered Diels-Alder conjugation is utilized to graft in an effective and straightforward approach poly(trifluoro ethyl methacrylate) (Mn = 3700 Da, Đ = 1.27) and a model peptide (GIGKFLHS) onto thin hyaluronan films and cellulose surfaces. The surfaces were functionalized with an o-quinodimethane m…
The hexagonal boron nitride (h-BN) is traditionally considered to be inert. In sharp contrast to the inert behavior of free-standing hexagonal boron nitride (h-BN), we propose the catalytic property of h-BN monolayer on Ni(111) substrate using first-principles density functional theory investigation. The interaction o…
