SAPO-34 membranes were synthesized using double structure directing agents (tetraethylammoniumhydroxide (TEAOH) and dipropylamine (DPA)). Using the secondary growth method, the seeds synthesized by hydrothermal process provided nucleation for the membrane growth and accelerated the zeolite crystallization. The prepare…

The process of plane stress local torsion (PSLT) is proposed as a localised severe plastic deformation for the enhancement of holes. The PSLT process is capable of creating large shear strains and consequently substantial grain refinement in the vicinity of the hole with a gradient in the radial direction. It is of gr…

Based on CFD (Computational Fluid Dynamics), the internal flow of SCR(Selective Catalytic Reduction) denitrification column is simulated. With the application of standard k- two equation model and porous media model, the velocity field of smoke movement is represented. The influence rules deflector put on smoke moveme…
This study focused on the design and synthesis of manganese oxide nanomaterials with nanoarray architectures. First of all, a straightforward synthetic strategy was discovered to fabricate manganese oxide nanoarrays on two-dimensional substrates (e.g. Si wafers and conductive FTO glass). Then, the generic one-pot hydr…
Nonwoven materials have attracted much interest in the industry due to their high surface area, high porosity, and low cost. However due to the complexity of deformation mechanisms in these materials, controlling the mechanical properties has been challenging. Therefore, it is important to establish the fundamental un…
Assessing the shear strength of a joined ceramic or CMC is an essential task in components design. Indeed, what is needed for design purposes, is the true shear strength, while several standard tests only give conventional values, disregarding multiaxiality and non-uniformity of the actual stress distribution. If used…
Micro- and nano-mechanical resonators with low mass and high vibrational frequency are often studied for applications in mass and force detection where they can offer unparalleled precision. They are also excellent systems with which to study nonlinear phenomena and fundamental physics due to the numerous routes throu…
This article describes the processes causing erosion of cathode of eddy-current fire detector in the field of the negative corona discharge. Photomicrographs of cathodes exposed to erosion are included. Factors affecting the erosion process are established.
Hyperfine Interaction technique like Mossbauer spectroscopy is a very sensitive tool to study the local probe interactions in Iron rich alloys. We report here the Mossbauer study of the effect of Fe concentration variations in Te doped FeSb1-x for x = 0.05, 0.10, 0.20 and 0.50 alloys. Also for a xvery dilute Fe concen…
As a new class of materials, metallic glasses (MGs) appear to have great potential for engineering applications, due to their superior properties including high strength, good corrosion resistance, thermoformability and etc. Despite several attractive traits of MGs, the main drawback lies in their little tensile and l…
With bandwidths exceeding 30-GHz, error-free bit rates exceeding 50-Gb/s, and energy efficiencies approaching 100-fJ/b, via innovative grating reflectors, added materials, and unusual device geometries methods to further enhance the performance 980-nm communication VCSELs are explored.
Исследованы спектры ЭПР ионов Gd3+, присутствующих в качестве малой примеси (~0.0001 at.%) в монокристалле LiYF4, в широком диапазоне температур от гелиевых до комнатных. На ряде компонент тонкой структуры спектра наблюдается четко выраженная суперсверхтонкая структура, зависящая от ориентации внешнего магнитного поля…

We propose a novel method for sampling single cells and intracellular biomolecules without losing spatial information in tissues or in single cells, using Si nano-blade array device. The device has an array of thin blade structures ranging from 300 nm to tens of μm in thickness. The blade design is easily arrangeable…
One of the filamentous viruses, M13 bacteriophage (phage), has attracted growing interest as a functional biopolymer assembly due to its liquid crystalline properties and designable functionalities based on genetic engineering and organic synthetic approaches. Recent studies revealed that phage could be utilized as su…
Granulation is a key factor towards improvement of the flowability of fine ceramic powders to make them suitable for industrial dry pressing.Controlled granulation of fine alumina particles with a primary particle size of ∼ 150 nm was carried out using spray-freeze drying, which led to the production of flowable granu…
Diamond-like carbon (DLC) films were prepared on silicon substrate using four different vacuum plasma methods: magnetron sputtering (MS), pulse laser ablation (PLA), ion beam deposition (IBD) and pulse cathode vacuum arc evaporation (CVAE). The microstructure, surface morphology and optical properties of the DLC films…
Ultrasonic welding offers ability to weld thin layers of malleable metals at low temperature and low power consumption. During ultrasonic welding, intensive material interactions occur due to the severe plastic deformation (SPD) and frictional heat generation, which leads to the microstructural change. Different grain…
