One of the contemporary challenges for cardiovascular tissue engineers is to design hemocompatible biomaterials that promote neo-tissue formation. Despite many years of intensive research materials used to fabricate synthetic implants still cause clot formation in the bloodstream, which can have fatal consequences for…

The small thiol β-mercaptoethanol (BME) has been used as an anti-blinking reagent for CdSe/ZnS quantum dots (QDs), although its effects on QD photoluminescence are complex. It acts as an antioxidant as well as a hole scavenger on both CdSe and CdTe, which leads to changes in emission intensity and lifetime that vary q…
BACKGROUND/AIMS: Recent advances in nanotechnology have made it possible to mass-produce ultrathin silicon membranes with pore sizes in the range of nanometers. In this study, we investigate the possibility of employing ultrathin nanoporous silicon membranes with pore diameters of 5 and 20 nm for dialysis of human who…
To assess the aquatic ecosystem safety of silicon dioxide (SiO2) nanoparticles (NPs), we studied the toxicity of the SiO2 NPs and SiO2 bulk particles (BPs) using zebrafish. Our results show that the SiO2 NPs can significantly affect the development of zebrafish embryos, while there is no obvious effect on survival and…
Due to the outstanding mechanical properties, carbon nanotubes (CNTs) are considered to offer the probability to enhance the properties of high-performance cementitious composites，and to reduce ecological cost of construction materials. Recent work in the area of concrete materials research has shown the potentiality…
A simple, room temperature reduction-hydrolysis of FeCl3 in H2O/Triton X-100 serving as a lyotropic hexagonal columnar liquid crystal template is an effective and mild approach for preparing highly crystalline iron/iron oxide nanosheets.
The present study describes the synthesis, characterization and photocatalytic potential of Ti oxide nanostructures of various morphologies and crystalline phases that were synthesized from 4 different precursors by the alkaline hydrothermal method. The materials were characterized by mainly X-ray diffraction (XRD), R…
Pentavalent vanadium compounds induce intracellular changes in vitro that are consistent with those of other carcinogenic substances. While there is no clear evidence that vanadium compounds cause cancer in humans, vanadium pentoxide causes lung cancer in rodents after long-term inhalation exposures and in turn IARC h…
Most spiral coiled biomaterials in nature, such as gastropod shells, are homochiral, and the favoured chiral feature can be precisely inherited. This inspired us that selected material structures, including chirality, could be specifically replicated into the self-similar populations; however, a physicochemical unders…
A novel plasmonic waveguide filter design based on three cascaded slot cavities is proposed. The cascaded nanocavities support a united resonant (UR) mode. Light is trapped in the middle nanocavity at telecommunication wavelength (1550 nm) when the UR mode exists. This phenomenon leads to the efficient transmittance a…
Reverse-amphiphilic core/shell polymeric nanoobjects (PNOs) with lamellar, cylindrical and spherical morphologies derived from poly(glycidyl methacrylate)-block-poly(n-butyl methacrylate) (PGMA-b-PnBMA) diblock copolymers were used as nanocapsules to encapsulate anionic hydrophilic dyes. Through the bulk self-assembly…
Iron oxide (Fe2O3) is a promising substitute for other hydrogen storage materials, which can store/produce hydrogen by a reversible redox process (Fe3O4 + 4H2 ↔ 3Fe + 4H2O). In order to evaluate the effectiveness of iron oxide for this purpose, a series of Mo-doped iron oxides (Fe2O–5%Mo, –8%Mo and –10%Mo) were prepar…
A low-cost and Mo(S,Se)2-free superstrate-type device structure is reported for the first time with the tunable band gap Cu2ZnSn(S1−xSex)4 nanocrystals. Using a facile hot-injection approach with only oleylamine reagent for synthesizing Cu2ZnSn(S1−xSex)4 nanocrystals with varied Se to (S + Se) ratio, the role of Se in…

For the preparation of nanocomposites, we conducted environmentally benign foaming processing on polypropylene (PP) copolymer/clay nanocomposites via a batch process in an autoclave. We investigated the dispersion and the exfoliation of the nanoclay particles. Full exfoliation was achieved by the foamability of the ma…
There is a long-standing demand for materials which could simultaneously demonstrate multiple promising properties like high strength, good ductility and toughness. In this study, a three-dimensional bulk nanocomposite material which is composed of nanoscale crystalline metal and metallic glass is revealed to present…
The 0.69Pb(Mg1/3Nb2/3)O3-0.31PbTiO3 (0.69PMN-0.31PT) ceramics were prepared by a partial oxalate route via the columbite precursor method, a modified columbite precursor method and the B-site oxide mixing route. X-ray diffraction (XRD) measurement confirmed that pure-phase perovskite 0.69PMN-0.31PT ceramics were prepa…
Leather industry is one of the polluting industries due to its generation of huge amounts of liquid and solid wastes; chrome tanned leather waste shavings are the most important of these wastes. From environmental and commercial point of view high added value material (technical gelatine) which having low content of c…
The bacterial pathogen Helicobacter pylori (Hp) is the leading risk factor for the development of gastric cancer. Hp virulence factor, cytotoxin-associated gene A (CagA) interacted with cholesterol-enriched microdomains and leads to induction of inflammation in gastric epithelial cells (AGS). In this study, we identif…
