The purpose of this study was to determine elastic strength of a high pressure vessel with a radial circular cross bore, for various thickness ratios and cross bore sizes. Seven cross bored cylinders with thickness ratios between 1.4 and
MoS 2 quantum dots (QDs) decorated NH 2 -MIL-125 (MoS 2 QDs/NH 2 -MIL-125) heterostructures were successfully fabricated by a facile method. XRD results exhibit that NH 2 -MIL-125 and MoS 2 form crystals in the synthesis process of MoS 2 QDs/NH 2 -MIL-125 heterojunctions. TEM results demonstrated clearly that the MoS…
The application of machine learning and nature-inspired optimization methods, like for example genetic algorithms (GA) and particle swarm optimization (PSO) can be found in various scientific/technical areas. In recent years, those approaches are finding application in accelerator physics to a greater extent. In this…
The controllable synthesis of manganese oxyhydroxide (MnOOH) nanomaterials was achieved via a simple solvothermal reaction in the presence of polyvinylpyrrolidone (PVP) and sodium dodecyl benzene sulfonate. The obtained MnOOH nanowires, nanonets, and nanorods were all used for the in-situ polymerization of aniline to…
Organic dye detection requires high sensitivity, low-cost equipment, simplified procedures, and real-time capabilities; thus, electrochemical methods are gradually emerging in this field instead of chromatography.
A green, rapid and facile method for synthesis of pure rutile TiO2 has been developed. Rutile TiO2 of high purity was synthesized by controlled hydrolysis of TiCl3 in aqueous medium at room temperature. Addition of nitric acid to TiCl3 greatly increased the rate of TiCl3 hydrolysis, crystallization and surface area of…
We present a novel virtual try‐on solution for fitting evaluation and pattern modification to design various types of garment and speed up the garment design process. In the phase of fit evaluation, we propose a method for producing two‐dimensional (2D) color maps by comparing a 2D triangle mesh panel garment and a 3D…
Rice husk is considered as agricultural waste that causes environmental problem during its handling. In this study, rice husk was treated with acid (citric acid and nitric acid) solutions prior used as raw material for producing biofuel and chemicals via pyrolysis. The pyrolysis behaviors of rice husk treated with wat…
Abstract— We have examined the effect of iron oxalate (Fe2(C2O4)3 · 5H2O) additions on the phase composition of combustion products of silicon–carbon mixtures in nitrogen. The phase composition of the combustion products has been determined as a function of starting-mixture composition and nitrogen pressure. We have i…
Resumo Durante o processo de soldagem o aço microligado ASTM A131 Grau AH36 pode apresentar defeitos oriundos dos ciclos térmicos (distorções) que demandarão procedimentos onerosos como o tratamento térmico pós-soldagem. Somando-se a isto, este aço não é indicado a sofrer normalização, normalização seguida por revenim…
Fluopyram is one of the widely used fungicides and it is persistence in water and soil. In this study, the photocatalytic degradation of fluopyram by TiO 2 was investigated under simulated solar light irradiation. Six transformation products (TPs) were identified by means of high performance liquid chromatography coup…
X-ray and electrophysical investigations of ceramics with a charge composition 95 mol % CeF3 × 5 mol % SrF2 synthesized by hot pressing of CeF3 and SrF2 powders (300 MPa, 900°С, 20 min) in vacuum and the same ceramics annealed in a fluorinating atmosphere (CF4, 1000°С, 180 min) have been carried out. The initial two-p…
/g were obtained. The resultant silica particles were modified by binding with chlorodimethyloctadecylsilane (C18) and by the thiol-ene click reaction to obtain a mixed-mode type stationary phase. The test results showed that the silica packing materials prepared in this work has certain applicability.
With an increased penetration of renewable energy sources such as solar and wind in the South African power network, maintaining power system stability during network disturbance poses a major challenge. This paper is used to describe how synchronous compensators generally help to boost grid inertia and improve networ…
Moisture content is one of the most important properties of wood. The primary purpose of this paper is to examine the dependence between thermal properties and different moisture contents of softwood, hardwood and medium hardwood samples with dimensions of 100 x 100 mm and a thickness of 10 mm (measured using the tran…
A unified theory for continuous and discontinuous annealing phenomena based on the subgrain growth mechanism was proposed by Humphreys about twenty years ago. With the developments in the unified subgrain growth theory, a number of Monte Carlo, vertex and phase-field (PF) simulations have been performed to investigate…
A characteristic fingerprint of atomic clusters is that their properties can vary in a non-smooth way with the cluster size N. This is illustrated herein by studying the cluster size dependence of several properties of neutral CN and cationic C+N carbon clusters: C-C bond lengths, cluster structure, intrinsic cluster…
Abstract A number of copolymers based on 4H-cyclopenta[2,1-b:3,4-b']dithiophene and 4H-dithieno[3,2-b:2',3'-d]silol are synthesized via direct С–Н arylation and Suzuki cross-coupling, and their properties are compared. The chemical structure of the copolymers is investigated by 1Н and 13С NMR spectroscopy, and their m…
The article presents the developed methods and algorithms for predicting the moment at which dangerous technical condition of a facility occurs based on a set of diagnostic parameter realizations of similar facilities. Application of the developed methods makes it possible to overcome a number of difficulties encounte…
Abstract Results of investigation of the mass spectra of secondary ions sputtered from bulk (continuous) and porous silicon targets with various characteristic core particle dimensions are presented. It has been established that the sputtering of nanostructured Si samples leads to a significant increase in the relativ…
