Abstract The flexible ZnO/SiO 2 hybrid nanofiber membrane was prepared via electrospinning followed by high-temperature annealing at 600 °C in the air. The hybrid membrane was researched to prepare a flexible pressure sensor, and the experimental results suggest that the flexible pressure sensor has excellent flexibil…
Abstract A direct Z‐scheme type α‐Fe 2 O 3 /FeVO 4 heterostructured photocatalyst with novel nanobelt structure just like the leaves of bryophyllum pinnatum has been successfully synthesized for the first time via integrating a facile electrospinning with annealing procedure. The as‐prepared products are characterized…
The use of RE-Ba–Cu–O [(RE)BCO] bulk superconductors, where RE = Y, Gd, Sm, in practical applications is, at least in part, limited by their mechanical properties and brittle nature, in particular. Alloying these materials with silver, however, produces a significant improvement in strength without any detrimental imp…
The need for the conformal deposition of TiO 2 thin films in device fabrication has motivated a search for thermally robust titania precursors with noncorrosive byproducts. Alkylamido-cyclopentadienyl precursors are attractive because they are readily oxidized, yet stable, and afford environmentally mild byproducts. W…
The pinning effect of adding the microalloying element Mg on the growth of austenite grain for low-carbon steel was investigated in this study. The grain growth pinning behaviour of austenite was observed in situ at high temperature using a high-temperature confocal scanning laser microscope at 1573 K for 300 s. The a…
Herein we followed the structural evolution of a prototypical type of porous organic cage, CC3, as a function of synthesis time. Three distinctive crystal formation stages were identified: at short synthesis times, a rapid crystal growth stage in which amorphous agglomerates transformed into larger irregular particles…
Amino acid-based amphiphiles have attracted much attention as environmentally friendly surfactants because of their biodegradability, low toxicity and the use of renewable sources of raw materials for their syntheses. With respect to molecular design, the amino acid-based architecture allows the possibilities of multi…
The discovery of the spontaneous reaction of boric oxides with moisture in the air to form lubricious H 3 BO 3 films has led to great interest in the tribology of boron compounds in general. Despite this, a study of the growth kinetics of H 3 BO 3 on a B 2 O 3 substrate under controlled relative humidity (RH) has not…
In this work, complex of Ni‐modified graphene oxide was prepared and characterized using FT‐IR spectroscopy, SEM, XRD, TGA and ICP‐OES techniques. This compound used as an efficient and recoverable catalyst for the C–S coupling reaction using sulfur‐transfer reagents (S8 or thiourea). The catalyst was easily separated…
We studied the formation of linked porphyrin oligomers from 5,15-diphenylporphyrin (2H-DPP) by thermal, substrate-assisted organometallic and dehydrogenation coupling on Cu(111) by scanning tunneling microscopy. In the range of 300-620 K, we find three distinct stages, at 300 K, the intact 2H-DPP molecules self-assemb…
Pancreas transplantation is considered as a promising therapeutic option with the potential to cure diabetes. However, efficacy of current clinical transplantation is limited by the donor organ. With regard to creating a functional pancreas-tissue equivalent for transplantation, vascularization remains a large obstacl…
Abstract Co‐immobilization of bio‐ and chemocatalysts produces sustainable, recyclable hybrid systems that open new horizons for green cascade approaches in organic synthesis. Here, the co‐immobilization of laccase and 2,2,6,6‐tetramethylpiperidin‐1‐oxyl (TEMPO) in mesoporous silica was used for the one‐pot aqueous sy…
The Sauter-Schwinger effect predicts the creation of electron-positron pairs out of the quantum vacuum via tunneling induced by a strong electric field. Unfortunately, as the required field strength is extremely large, this fundamental prediction of quantum field theory has not been verified experimentally yet. Here,…
Abstract The sensitivity study of propellants has been receiving heightened attentions from a lot of investigators. These propellants based on nitrocellulose are sensitive to accidental stimuli that result in catastrophic accidents. Thus energetic thermoplastic elastomers have been used as binders to replace some nitr…
The La-substitution and pressure effects on antiferromagnet CeCoSi with a tetragonal crystal structure were investigated in order to clarify the origin of the pressure induced ordered phase (PIOP) with an enormously high transition temperature of T0 ∼ 38 K. By substituting Ce with La, the PIOP shifts to high pressures…
Abstract Mn3O4 nanoparticle‐decorated carbon cloths are prepared as the electrodes for vanadium redox flow batteries. The Mn3O4 nanoparticles are prepared using a two‐step process, in which MnOOH nanoflakes are electrodeposited on the surface of the carbon cloth and subsequently converted to Mn3O4 nanoparticles by a t…
This study presents the theory for liquid–liquid phase separation for systems of molecules modeling monoclonal antibodies. Individual molecule is depicted as an assembly of seven hard spheres, organized to mimic the Y-shaped antibody. We consider the antibody–antibody interactions either through Fab, Fab′ (two Fab fra…
In this study, polyamide-aluminum foil-polypropylene (PA-Al-PP) composite films with different orientation status of the PP layer were prepared, and their morphology, tensile, peeling and heat seal behavior were studied. The comparative study of tensile and fracture behaviors of single-layer film of PA, Al and PP, as…
The highly hydrophobic poly(ether sulfone)/fluorinated silica (PES/fSiO 2 ) organic–inorganic composite membrane for sulfur dioxide (SO 2 ) desulfurization was prepared by incorporating the fSiO 2 particles on the PES membrane via sol–gel process and fluorination. The formation of PES/fSiO 2 organic–inorganic composit…
Maintaining cell viability within 3D tissue engineering scaffolds is an essential step toward a functional tissue or organ. Assessment of cell viability in 3D scaffolds is necessary to control and optimize tissue culture process. Monitoring systems based on respiration activity of cells (e.g., oxygen consumption) have…
