The synthesis of a Ca-modified (K,Na)NbO 3 one-dimensional nanowire with a polycrystalline phase boundary and its investigation by convergent beam electron diffraction (CBED).
Over the past few decades interest in metallic nanoparticles and their synthesis has greatly increased. This has resulted in the development of numerous ways of producing metallic nanoparticles using chemical and physical methods. However, drawbacks such as the involvement of toxic chemicals and the high-energy requir…
This study reports on-axis sputter deposition of Hf0.5Zr0.5O2 thin films on platinized silicon substrates (Pt/Al2O2/SiO2/Si) as well as boron doped silicon substrates (P-Si), using a table top RF-magnetron sputtering unit. Through optimization steps of deposition parameters, as revealed by X-ray photoelectron spectros…
The present paper provides a systematic treatment of modern differential-geometrical methods for modeling of incompatible finite deformations in solids and thin walled structures. The incompatibility of deformations may be caused by a variety of physical phenomena; among them are: growth, non-uniform thermal fields, s…
Solution of Z907 dye in two different solvents, namely ethanol (EtOH) and chloroform (CHCl3) are prepared and utilized in dye-sensitized solar cells (DSSCs). The effects of dye solvents on the performance of these cells have been investigated and the results are represented. The DSSCs that used EtOH as a dye-adsorptio…
For the safe operation of devices comprised of bodies with D∞ symmetry, the electroelastic field in a solid cylinder subjected to a non-axisymmetric surface load of radial and circumferential stresses was investigated. The analytical technique constructed previously, the Fourier integral technique with respect to the…
The keyhole which is typical for laser deep penetration welding is responsible for the highly dynamic process behavior, which results in unwanted pore and spatter formation. This work aims to better understand the dynamic keyhole properties and occurrence of process defects. Therefore, a semi-analytical model is devel…
were generated in 65 : 30 : 5 ratio, and 62% of deuterium atoms were incorporated into the major product, the dimethylaminoborane dimer. Proton and deuteron nuclei were thus concentrated into the evolved dihydrogen and aminoborane dimer, respectively. The mechanism of H/D scrambling is understood based on the reaction…
Thus, at present, a large amount of rubber waste cannot be higher harnessed due to recovery technologies used. Also, the requirements for new products of rubber worldwide are greater than the production capacity and the availability of raw materials. To offset this balance is necessary to improve technologies for recy…
Welcome to this CrystEngComm themed issue entitled “Covalent Organic Frameworks and Organic Cage Structures”.
This research aims to prepare, characterize, and determine the metal particles of Molybdenum (Mo) and Cobalt (Co) metal on the supporting material Mordenite, Ultra Stable Y-Zeolite (USY), and Natural Zeolite (ZAA). In this research the catalysts were prepared, activated, and characterized. The bimetallic catalysts CoM…
In a recent article Toro-Mendoza et al. considered an elastic response of an interface in order to explain the enhanced lateral drag of solid particles straddling fluid interfaces we recently measured.
To fulfill the industrial demand of forged steels with high tensile properties and microstructural requirements coupled with reduced cost, the possibility to increase the properties of C-Mn steels by means of precipitation strengthening as achieved by micro-alloying (and without the addition of expensive elements such…
Porous tubular TiO2 powders were prepared first via a novel facile and non-template route of the nonhydrolytic sol–gel method. The as-prepared TiO2 powders could then be directly converted into porous tubular TiN powders through an ammonia reduction nitridation process. The results indicated that the obtained TiO2 pow…
Abstract This paper presents the calibration of Eringen’s small length scale coefficient
A 7-hydroxy derivative of 3-methyleneisoindolin-1-one 1 was synthesized and its properties as a new fluorophore undergoing excited-state intramolecular proton transfer (ESIPT) were investigated. In alcohols and dimethylsulfoxide, 1 exhibited dual emission at ca. 380 and 525−540 nm when excited at ca. 336 nm, which agr…
The paper deals with the causes and consequences of malfunctioning of natural and mechanical ventilation systems in civil buildings of Russia. Furthermore it gives their classification and analysis based on the literature review. On the basis of the analysis technical solutions for improving the efficiency of ventilat…
近年，世界のプラスチック生産量が増加している中で，資源利用効率の観点および省エネルギーの観点からプラスチックリサイクル技術の意義はますます高まっている．本論文ではプラスチックリサイクル，とりわけ，高収率のモノマー回収や原燃料としての再利用が可能で，発生したガスや残渣も活用できる手法を含むフィードストックリサイクル（Feedstock Recycling）に焦点を当て，新たな技術動向および課題について論じた．さらに，プラスチックリサイクル研究および技術開発の現状に関して国際比較を行った．その結果，産業分野や家庭から実際に排出されるプラスチックの組成がますます複雑化してきている中でリサイクルの技術的課題が増大していることが示唆された．…
O solution, and only intensified single normal blue fluorescence emission was presented. This study provided real examples of some branched organic dye aggregates which were capable of displaying naked-eye enhanced fluorescence color switching under an UV lamp.
Nanostructured cadmium oxide thin films have been synthesized onto suitably cleaned glass substrates by SILAR (successive ionic layer adsorption and reaction) method. X-ray diffraction study confirms the formation of nanocrystalline cubic phase of cadmium oxide in the films. Lattice constant is determined using Nelson…
