We have fabricated a BiOBr film for the first time through water-air interfacial self-assembly, which is a green, easily processable and environmentally friendly strategy. Moreover, an ultraviolet photodetector based on the BiOBr film exhibited excellent stability and a fast response time.
The effects of the temperature on the structure of a single layer of graphene on Ir(111) have been investigated in situ in the growth chamber by grazing incidence x-ray diffraction between 10 and 1300 K. In addition, the effect of two growth temperatures has been studied. The graphene lattice parameter of the main, no…
Abstract Here, we demonstrate the synthesis of graphene on Ag foil by an atmospheric‐pressure (AP) chemical vapor deposition (CVD) process as tarnish‐resistant coating. Synthesis of a continuous graphene film on Ag foil is achieved using the solid camphor as carbon precursor in a gas mixture of Ar and H 2 . Tarnishing…
Polyurethane nanocomposites are versatile engineering polymers with unique properties. In this study, nano hexagonal boron nitride containing thermoplastic polyurethane elastomers were prepared via melt blending and hot‐pressing techniques. The nanocomposites were characterized using Fourier transform infrared, differ…
The use of composite materials reinforced with natural fibers has been widely studied in recent research seen the availability of feedstock and mainly because the productions facility, low cost and because they are biodegradable. In order to expand the applications of composite materials, this paper proposed to develo…
We report that high transport critical current density exceeding 104 A/cm2 at 4.2 K and 10 T can be obtained with good reproducibility for Ag sheathed (Ba,K)Fe2As2 (Ba 122) tapes by modifying the ex-situ powder-in-tube (PIT) method. The process involves cycles of the cold deformation and subsequent heat treatment. The…
In this Letter, we discuss the results of Hall effect measurements to examine the electrical properties of the graphene films synthesized by low-temperature microwave plasma chemical vapor deposition. Van der Pauw devices with sizes of 50–100 μm were fabricated, for which we observed p-type conduction and mobility fro…
Morphology control of one dimension (1D) nanomaterials is a pivotal issue in the field of nanoscience research to exploit their novel properties. Herein, we report the morphology controlled synthesis of 1D β-Sialon nanowires, nanobelts and hierarchical nanostructures via a thermal-chemical vapour deposition process us…
Gradient index (GRIN) structures have attracted great interests since their invention. Especially, the recent advance in the fields of transformation optics, plasmonics, and nanofabrication techniques has opened new directions for the applications of GRIN structures in nano-photonic devices. In this paper, we apply Lu…
Piezoelectrics and ferroelectrics have been widely used in modern industries because of their peculiar electromechanical coupling properties, quick response, and compact size. In this work, we give a comprehensive review of our works and others' works in the past decade on the multiscale computational mechanics method…
Boronic acids are versatile reagents for the chemical synthesis of organic molecules. They and other boron-containing compounds can be detected readily by the interruption of the excited-state intramolecular proton transfer (ESIPT) of 10-hydroxybenzo[h]quinolone. This method is highly sensitive and selective, and usef…
New sequence of microcapsules with dendritic PAMAM-based novel polyurea as shell wall material containing herbicide as a core moiety has been prepared by interfacial polymerization technique. Dendrimer-based polymeric microcapsules were fabricated with aim to study the effect of different reaction parameters such as s…
The cobalt nickel ferrite ( C o 1‐x N i x F e 2 O 4 x = 0–1.0) nanoparticles were synthesized by a hydrothermal method. Effects of nickel content and organic template on the microstructure and magnetic property of the nanoparticles were studied. The experimental results indicate that N i 2+ substitution for C o 2+ and…
Results of a pioneering study are presented in which for the first time, crystallization, phase separation and Marangoni instabilities occurring during the spin-coating of polymer blends are directly visualized, in real-space and real-time. The results provide exciting new insights into the process of self-assembly, t…
Mueller matrix polarimetry (MMP) is introduced to characterize nanoimprinted grating structures, and noticeable depolarization effects from measured data are observed. We demonstrate that these depolarization effects are mainly induced by the finite bandwidth and numerical aperture of the instrument, as well as the re…
Multi-level phase change character of superlattice-like (SLL) Sb50Se50/Ga30Sb70 thin films was investigated through in-situ film resistance measurement. SLL structure of the thin films was confirmed by using transmission electron microscopy. Three resistance states were observed during heating process, and their therm…
We report optical birefringence data by two different methods with high temperature resolution for octylcyanobiphenyl (8CB) near the smectic-A to nematic (Sm-A-N) phase transition temperature T(AN). Within the resolution of our experiments, we find that the Sm-A-N phase transition is continuous. For a possible discont…
Porpholactones, with one porphyrin β,β′-double bond replaced by a lactone moiety, possess unusual electronic states and photophysical properties between porphyrin and chlorin. However, such optical properties and unique structural characteristics have rarely been investigated within biological studies. In this work, w…
The properties of short glass fiber reinforced thermoplastic based on polyamide 6 in humid environment are studied. Conditioning was conducted at 90°C. The combined action of water and heat (90°C) affects progressively the mechanical properties. When the injection molded samples were subjected to moisture, decrease in…
We report on anomalies in the dielectric and optical phonon spectra in bulk orthorhombic distorted perovskite LaCrO3 near an antiferromagnetic transition at 290 K. These anomalies were tracked using temperature dependent (200 K–320 K) dielectric and Raman spectroscopy. We observed a blue-shift for the B3g(3) optical p…
