Magnetic materials, both hard and soft, are used extensively in several components of particle accelerators. Magnetically soft iron-nickel alloys are used as shields for the vacuum chambers of accelerator injection and extraction septa; Fe-based material is widely employed for cores of accelerator and experiment magne…
The aim of our study was to elucidate the fundamental cooling characteristics and to improve the cooling characteristics of a room-temperature magnetic refrigerator operated under an active magnetic regenerator (AMR) cycle. The AMR refrigeration cycle, which includes a thermal storage process and a regeneration proces…
The photochemistry of Pauson-Khand cycloadducts of norbornadiene with a series of bis-aryl alkynes has been studied. Two types of photochemical transformation take place: photorearrangement to tricyclic ketones or photochemical 6π electrocyclization. High selectivity levels have been attained for each pathway, control…
Various methods for the production of bulk nanostructured (NS)/ultrafine-grained (UFG) materials have been developed, including equal channel angular extrusion (ECAE), a form of severe plastic deformation. Using an ECAE NS/UFG copper bar as an example, this study has investigated machining-induced workpiece microstruc…
Kinetic studies for the non-isothermal decomposition of un-irradiated and γ-irradiated indium acetyl acetonate In(acac)3 with 10² kGy total γ-ray dose were carried out in static air. The results showed that the decomposition proceeds in one major step in the temperature range of 150-250 °C with the formation of In2O3…
Knowing the freeboard levels of a yacht is crucial for boat builders and hull designers because it allows them to easily obtain precise information about the ship displacement, as well as about its trim. This paper describes a system that automatically performs the freeboard acquisition (substituting the rudimental an…
This paper presents the design, fabrication, and characterization of silicon-micromachined thermoelectric generator (TEG) modules (13-mm diameter and 0.36 mm thick) for power generation from hot gas streams. Individual TEG modules consist of radially oriented thermoelements on a thermally insulating annular polyimide…
Abstract In this study, the solution‐mixing method was used to prepare polymethacrylate derivatives' (PaMAs) nanocomposites with kaolinite. It was observed that the resultant materials could include exfoliated, intercalated, and undispersed kaolinite depending on their XRD patterns. TEM micrographs also revealed that…
The solubility of pioglitazone hydrochloride (form I) in methanol, ethanol, 1-propanol, acetic acid, and N, N -dimethylacetamide has been measured between 278.15 and 323.15 K at atmospheric pressure. The solubility of pioglitazone hydrochloride (form I) increases with increasing temperature and the order is N, N -dime…
Tris-sarcosine calcium chloride [(TSCC), (${\mathrm{CH}}_{3}{\mathrm{NHCH}}_{2}\mathrm{COOH}){}_{3}{\mathrm{CaCl}}_{2}$] is a uniaxial ferroelectric (FE) with a displacive second-order phase transition near ${T}_{c}=130$ K. A continuous range of solid solutions can be made by substituting Br for Cl, which lowers ${T}_…
In the process of high‐level nuclear waste (HLW) disposal, monazite, LaPO 4 is considered as one of the potential phosphate ceramics to immobilize lanthanides and actinides. HLW along with hazardous long‐lived nuclides contains elements such as Zr, Mo, etc. in higher wt%. In the current investigation, an attempt was m…
The paper presents the results of an attempt to use the magnetoacoustic emission (MAE) signal for the nondestructive evaluation of plastic deformation levels in samples subjected to tensile loading. Four varied materials have been investigated: 13HMF, CSN12021 and P91 steels and commercially available Armco Iron. As i…
The calculated electron mobility for a graphene nanoribbon as a function of applied electric field has been found to have a large threshold field for entering a nonlinear transport regime. This field depends on the lattice temperature, electron density, impurity scattering strength, nanoribbon width, and correlation l…
Noncovalent polymer sorting of single-walled carbon nanotubes (SWNTs) was carried out using polyvinylpyrrolidone (PVP) in dimethylformamide (DMF) solvent. With long-term (i.e., 14-day) standing of SWNTs/PVP/DMF in ambient condition, the semiconducting SWNTs remain suspended in solvent while metallic SWNTs precipitated…
The paramagnetic dinuclear complexes 1,8-bis(cobaltocenyl)naphthalene (2) and 1,8-bis[(pentamethyl-η(5)-cyclopentadienyl)(η(5)-cyclopentadiendiyl)cobalt(II)]naphthalene (4) were synthesized. The molecular structures were characterized by X-ray structure analysis and consisted of two cobaltocenes linked through a disto…
We discuss the analytical solution through the cavity method of a mean-field model that displays at the same time an ideal glass transition and a set of jamming points.We establish the equations describing this system, and we discuss some approximate analytical solutions and a numerical strategy to solve them exactly.…
Based on a two-step linear optical transformation method, a homogeneous-materials-constructed electromagnetic field concentrator whose energy concentrating ratio varies with the incident angle of the electromagnetic wave is proposed. The design is achieved by compressing the space in different directions with differen…
An investigation of the structure and drug release mechanism of a drug delivery system is proposed on the basis of semi-empirical and ab initio computations in vacuum stage. Cis-aconityl linkage is used to improve the interaction between an anti-cancer agent, doxorubicin, and a glycol chitosan biopolymer. It has been…
Co films with various thicknesses were selectively deposited as Cu capping layers by chemical-vapor-deposition technique. Selectivity of the Co deposition between Cu and dielectric surfaces was improved by raising the deposition pressure. Degree of electromigration (EM) resistance enhancement was observed to be depend…
Abstract Large‐scale high‐quality SrWO 4 nanocrystals have been synthesized in aqueous solutions under mild hydrothermal conditions with citrate as a simple additive. The crystals undergo an interesting 0‐D to 1‐D and to 0‐D morphology changes and have been characterized by X‐ray diffraction (XRD) and transmission ele…
