Printed chalcopyrite thin films have attracted considerable attention in recent years due to their potential in the high-throughput production of photovoltaic devices. To improve the homogeneity of printed CuInSe 2 (CISe) layers, chemical additives such as binder can be added to the precursor ink. In this contribution…
This paper presents an accurate thermal characterization of thin-film heaters manufactured on glass substrates. The characterization has been performed on Cr/Al/Cr meandered heaters. Techniques commonly adopted for measuring the temperature coefficient of resistance, the thermal resistance and thermal capacitance in t…
A facile diethylenetriamine-assisted protocol is developed to prepare dodecahedral α-Fe 2 O 3 nanocrystals, which exhibit efficient photoelectrocatalytic water splitting activity.
In this study, we demonstrated that the improvement of detection capability of cadmium sulfide (CdS) photoconductors in the ultraviolet (UV) regime is much larger than that in the visible regime, suggesting that the deep UV laser-treated CdS devices are very suitable for low-light detection in the UV regime. We determ…
A concept based on superdirective reradiation is presented for the sake of backscattering enhancement of a thin conducting plate at edge-on incidence. A passive structure consisting of a thin plate loaded with two conducting posts is proposed to demonstrate the concept. Through properly choosing the heights of two pos…
In order to predict the detonation velocity of high-nitrogen compounds, the following calculated descriptors, Q, ρ, and ΔE of 54 high-nitrogen compounds were calculated using DFT-B3LYP method with the 6-31G** basis set, which were then used to build the linear and nonlinear multivariable models by multiple linear regr…
The nitrogen-containing austenitic stainless steel 316LN has been chosen as the material for nuclear main-pipe, which is one of the key parts in 3rd generation nuclear power plants. In this research, a constitutive model of nitrogen-containing austenitic stainless steel is developed. The true stress-true strain curves…
The biological diversity among Stramenopiles is striking; they range from large multicellular seaweeds to tiny unicellular species, they embrace many ecologically important autothrophic (e.g., diatoms, brown algae), and heterotrophic (e.g., oomycetes) groups. Transcription factors (TFs) and other transcription regulat…
In their article, Zhang et al. [Phys. Rev. B 86, 024516 (2012)] present a remarkable result for ${A}_{x}{(S)}_{y}\mathrm{TiNCl}$ compounds ($\ensuremath{\alpha}$-phase TiNCl partially intercalated with alkali $A$ and optionally co-intercalated molecular species $S$), finding the superconducting transition temperature…
Binary BiOI/TiO2 hybrid material was synthesized via a sol-gel method combined with chemical etching. The as-prepared powders were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectroscopy (DRS), photoluminescence spectra (PLS) and photocurrent response t…
Three TiO 2 loaded composites, TiO 2 /kaolin, TiO 2 /diatomite, and TiO 2 /zeolite, were prepared in order to improve the solar-light photocatalytic activity of TiO 2 . The results showed that the photocatalytic activity could obviously be enhanced by loading appropriate amount of inorganic mineral materials. Meanwhil…
The effect of polycarboxylate ether (PCE)-based superplasticiser on the fresh and hardened properties of calcium aluminate cement (CAC)-based materials was investigated. Cohesion of the fresh mortar was improved by addition of methyl cellulose, thus avoiding segregation induced by the superplasticiser action. As PCE s…
In this paper, ZnO submicrospheres are prepared by a simple laser‐stimulated surface tension energy release strategy, which is a very convenient method for growing inorganic oxide spheres with high melting points. The detailed morphology evolution of ZnO particles is investigated by changing the laser fluence. The for…
This letter presents a highly sensitive near-infrared (IR)$a$-Si:H phototransistor for touch sensor applications. The narrow bandgap of$a$-Si exhibits a wideband spectrum response from IR to ultraviolet region, where the IR bandpass filter layers allow the$a$-Si:H phototransistor to respond to the selective IR light u…
The new type of Mg–8Al–1Sn (AT81) magnesium matrix composites reinforced with different volume fractions (5, 10, 15, 20, 25 and 30 vol.-%) of SiC particles (average size of 10 μm) was fabricated by powder metallurgy. With the increasing volume fraction of SiC particles (SiCp), the particles gradually show more homogen…
We investigate the effect of pore confinement and molecular geometry on the adsorption and self-diffusion of H2O, CO2, Ar, CH4, C3H6, SF6 and C5H12, in a realistic model of nanoporous silicon carbide derived carbon (SiC-DC), constructed using hybrid reverse Monte Carlo simulation. Adsorption isotherms, adsorbate–adsor…
To enhance the stability of a catalyst that uses alginate as a carrier, Ag nanoparticle-loaded glutaraldehyde-crosslinked calcium alginate (Ag/CA@GTA) hydrogel beads were prepared. The Ag/CA@GTA hydrogel beads were characterized by UV-visible spectroscopy, X-ray diffraction, Fourier-transform infrared spectroscopy, tr…
The modification of multispin casting multilayered barium titanate (BTO) thin films on indium tin oxide (ITO)/glass substrate without doping other elements is adopted to improve the memory performance. The X-ray photoelectron spectroscopy analysis reveals the concentration of oxygen vacancies can be reduced by the inc…
In the domain of magneto transport properties of materials, giant magnetoimpedance (GMI), is of research interest as it represents a large change of both real and imaginary parts of the impedance under a static magnetic field applied. Understanding of GMI needs the understanding of the micro magnetic characteristics o…
Present investigations involve a systematic study on the machinability of austempered ductile irons (ADI) developed from four commercially viable ductile irons alloyed with different contents of 0, 0.1, 0.3 and 0.6 wt.% of Ni. The influence of Ni content, amount of retained austenite and hardness of ADI on machining b…
