Squeeze casting process of Zamac 5 for obtain faucets enables higher productivity associated with better dimensional characteristics. In this process, the die cooling system can influence the solidification of the alloy and its properties. This study evaluates the influence of die temperature on solidification under p…
Monodispersed SnO2 microspheres with diameter about 1 μm were successfully synthesized by solvothermal method at 180 OC for 12 h, using PEG as template, SnCl4•5H2O and urea as raw materials. Effects of concentration and molecular weight of PEG, hydrothermal temperature on the morphology of SnO2 microspheres were studi…
Multiple-junction solar cells made from III-V compound semiconductors are delivering the highest solar-electric conversion efficiencies. Increasing the number of junctions offers the potential to reach higher efficiencies. Direct wafer bonding offers a unique opportunity to combine lattice mismatched materials through…
The complex macroscopic mechanical behavior due to the polycrystalline texture evolution under complex loading paths cannot be efficiently captured by the classical isotropic and kinematic hardening constitutive equations. The complex physical interplay of different directional texture leads to an evolving shape of th…
[Hmim]HSO 4 -based microemulsion is an efficient catalyst system for esterification; it provides large interface areas, the resultant water enters [Bmim]BF 4 microdomain.
Flower-like Cu 2 ZnSnS 4 (CZTS) nanoflakes were synthesized by a facile and fast one-pot solution reaction using copper(II) acetate monohydrate, zinc acetate dihydrate, tin(IV) chloride pentahydrate, and thiourea as starting materials. The as-synthesized samples were characterized by X-ray diffraction (XRD), Raman sca…
Performances of the Bragg-edge transmission imaging at a compact accelerator-driven pulsed neutron source (pulsed CANS) are presented and evaluated. This technique is expected to be a new material analysis tool that can quantitatively visualize crystalline microstructural information inside a bulk material over large…
CoFeB-MgO based magnetic tunnel junctions with perpendicular easy axis are attracting much interest for application to nonvolatile very large scale integrated circuits. MgO/CoFeB/Ta/CoFeB/MgO recording structure with double-interface shows a high thermal stability factor without an increase of intrinsic critical curre…
Hydrogenated amorphous silicon (a-Si:H) layers deposited by chemical vapour deposition provide an attractive route to achieve high performance crystalline silicon (c-Si) solar cells due to their deposition at low temperatures and their superior passivation quality. A post-deposition annealing of such layers typically…
The degradation of Alizarin Red S by electro-generated species using Pt and BDD electrodes was performed. The results were explained by the generation of OH * radical, S2O8 2-at BDD electrode and active chlorine species at Pt electrode. The slow degradation is affected by the current density, initial pH, temperature,…
Japanese swords are peculiar ones forged by a unique method developed in Japan. The forging methods are different each other, depending on age and area. Therefore, the crystalline structure of a Japanese sword depends on the age and the area. In this study, we obtained crystallographic information of Japanese swords a…
A multi-functional molecular porous zirconium-organic material, CAUMOF-12, has been discovered.
Silicon nanowires have been synthesized by a simple process using a suitable support containing silica and carbon microspheres. Nanowires were grown by thermal chemical vapor deposition via a vapor‐liquid‐solid mechanism with only the substrate as silicon source. The curved surface of the microsized spheres allows arr…
Existing thermal modelling and monitoring solutions cannot predict, detect and prevent hot spots caused by changes in the surrounding thermal environment for underground cables. Using Distributed Temperature Sensing (DTS) can provide you with a real time temperature profile of the underground cable. The benefits of th…
This Introductory Lecture is intended to provide a background to Faraday Discussion 174: "Organic Photonics and Electronics" and will consist of a chronological, subjective review of organic electronics. Starting with "ancient history" (1888) and history (1950-present), the article will take us to the present. The pri…
Fischer-Tropsch synthesis (FTS) reaction for the direct production of gasoline range hydrocarbons (C5-C9) from syngas was investigated on Ru, Pt, and La promoted Co/ZSM-5 (Si/Al = 25) catalysts. The hybrid catalysts were characterized by BET surface area, XRD, H2-TPR, NH3-TPD and XPS analyses. These physico-chemical p…
A Bearingless Switched Reluctance Motor (BSRM) has a complicated character of nonlinear coupling; therefore, it is a hard work to operate BSRM stably. In this paper, a new type of BSRMs with novel rotor structure is proposed by analyzing relationships between motor structure and theoretical formulae of levitation forc…
INTRODUCTION: Nanotubes are assumed to contribute to a significant exacerbation of asthma and to enhance the risk of profibrotic effects in lungs being affected by this injury. Therefore, deposition of nanotubes in the lungs of subjects with different ages was subject to a detailed theoretical investigation. METHODS:…
Permanent magnetic stirring is superior in terms of cost and operability compared with electromagnetic stirring. However, it is applied only to melting furnace. In this study, attempts were made to apply permanent magnetic stirring molten metal, and the effects of the stirring on grain refinement, increase in hardness…
Fischer-Tropsch synthesis (FTS) using a Co–Mn/oxidized diamond (O-Dia) catalyst was compared among a fixed bed reactor (FBR), a trickle bed reactor (TBR), and a slurry phase reactor (SPR). For TBR and SPR, hexadecane was employed as a solvent. Regardless of the reactor, the addition of 10 mol% of Mn to Co/O-Dia cataly…
