Shape memory alloys (SMA) are smart materials with the ability to remember a previous imprinted shape after plastic deformation. The shape memory actuator effect is induced by thermal energy. Its bases on crystalline transformation of NiTi-alloys from the austenitic B2 to the martensitic B19′ phase. Usually, SMA actua…
To optimize pulse field magnetization processes for high-temperature superconducting (HTS) bulk magnets, it is important to control the magnetic field amplitude and the driving temperature. Many publications have reported on the experimental and numerical results of the pulsed-field magnetization method. In the numeri…
In this paper, we use mixed-period grooves to surround a subwavelength slit to realize multiple extraordinary transmittance peaks for transmitted light. The mixed-period grooves refer to a set of 1-D grooves arranged with particular groove pitches, which are formed by merging two sets of 1-D periodic grooves with simi…
Shape memory alloys experience phase transformation from austenite to martensite around crack tip. When the crack advances, martensitic transformation occurs at the tip and the energy that goes into transformation results in stable crack growth like in the case of plastic deformation. In literature, there are studies…
Machine tools for small work pieces are characterized by an extensive disproportion between workspace and cross section. This is mainly caused by limitations in the miniaturization of drives and guidance elements, since their physical working principle necessitates certain minimum sizes. Due to their high specific wor…
Tabulated mass absorption coefficient data from the XCOM, Chantler and ion beam analysis (IBA) Handbook are compared, and differences are shown against X‐ray energy and target atomic number. Over the X‐ray energy range 1–40 keV systematic differences of several tens of percent are noted between these datasets, particu…
SUMMARY Appropriate monitoring and maintenance become important as an oil‐immersed transformer ages. Generally, dissolved gas analysis (DGA) is effective for the online diagnosis, and if an abnormality is detected, frequency response analysis (FRA) is effective for the offline diagnosis to localize the failed part. FR…
Titanium dioxide is a versatile material with ubiquitous applications, many of which are critically linked to either light absorption or transparency in the visible spectral range in addition to electrical conductivity. Doping is a well-known way to influence those properties in order to bring them into a desired rang…
Abstract Thermodynamic behavior of a ternary system with one low molecular weight component, formic acid (FA) as the solvent, water (non-solvent), and two high molecular weight polymers [polyamide-6 (PA-6) and cellulose acetate (CA)] was investigated using an extended modified Flory-Huggins model. Where, all chemicals…
In the present paper, we report our efforts on the development of metal tungstate alloys for efficient and economical photoelectrochemical water splitting. As suggested by density functional theory (DFT), the addition of copper to the host tungsten trioxide improves the visible light absorption. Past studies at the Ha…
Laminated and blending composites are designed to study the interfacial effects on the overall conductivity based on materials with different conductive mechanisms. The blends exhibit porous morphology because of the phase separation among the components, providing lager contacting areas between polymer chains and ion…
The equations describing the second-order phase transitions at the hydrostatic and non-hydrostatic pressures are considered. It is shown that the proportionality coefficient between an “effective” volume and the true one V∗ = AV is inversely proportional to the compressibility of the solid at a uniaxial pressure and h…
The structure and magnetic behavior of Cu-substituted Sr2+Ti4+O3-δ (STCu) thin films with ∼22% Cu on the Ti sites, grown on CeO2/yttria stabilized zirconia buffered (001) Si substrates were investigated. STCu films grew with (110) orientation or with a mixed (001)+(110) orientation and were under in-plane compressive…
A new tetrachlorocobalt(II) salt, [QlH]2[CoCl4]·2H2O(1) ([QlH]+ = quinolinium), has been prepared and characterized by elemental analysis, IR, UV-Vis, ESI-MS, single-crystal X-ray diffraction, and magnetic susceptibility. Compound 1 crystallizes in the monoclinic space group C2/c with cell dimensions a = 11.848(2) Å,…
We present ab initio calculations to find the migration pathways of the hydrogen atom through Stone-Wales defects into the inside of the double-shell fullerene. We report that the most favorable pathway consists of the tunneling pathway through Stone-Wales defects on the double-shell C60/C240 fullerene. This tunneling…
A simple indole-based receptor 1 was prepared by a simple Schiff-base reaction of 1H-indole-3-carbaldehyde with ethane 1,2-diamine and its fluoroionophoric properties toward anions were investigated. Indole-based receptor 1 acts as a selective turn-on fluorescent sensor for HSO4(-) in methanol among a series of tested…
A previously screened "hit chemistry" (N-[3-(dimethylamino)propyl] methacrylamide) that supports strong attachment and long-term self-renewal of ES cells is selected and grafted to poly(ether sulfone) (PES) fibrous matrices through plasma-induced graft polymerization. The 3D modified fibers exhibit higher cell prolife…
Advanced fiber reinforced ceramic composite having self-healing function (shFRC) has been developed. The composite includes the silicon carbide interlayer as healing agent at the interface between alumina fiber and alumina matrix. The healing agent interlayer caused the preferential fracture of the fiber/matrix interf…
We have presented direct evidence of crystallographic structural phase coexistence in a fast‐neutron‐irradiated Ce(Fe0.96Ru0.04)2 intermetallic compound. The ferromagnetic (FM) cubic phase slowly transforms into antiferromagnetic (AFM) rhombohedral phase at low temperature. Though the FM to AFM transition is first ord…
