We have analyzed the structural and magnetic properties of as-grown and annealed [TbFe2/Fe3Ga]n heterostructures grown by sputtering. Evidence of the bcc structure in the Fe3Ga layers has been found. The diffraction peak related to this structure shifts to high angles with the annealing temperature. Also, we have obse…
We report the synthesis and mesomorphic properties of a homologous series (10a–10g) of bent-core molecules constructed through covalent linkage of structurally non-symmetrical rod-like mesogens connected with a 1, 3-phenylene unit. The study of homologous series underlines the importance of length and nature of termin…
The complete elastic tensors of SmScO3 and NdScO3 were measured using resonant ultrasound spectroscopy (RUS) in combination with ab-initio calculations. Measurement of the elastic tensor of these recently synthesized single crystal RE scandates is essential for understanding dynamic lattice applications including phon…
Facing zinc bisporphyrins connected with diethanoanthracene and diethanonaphthacene (syn-1 and syn-2) are prepared by double [3+1] porphyrin synthesis of tripyrranedicarbaldehyde with syn-5,11-dimethoxy-4,6,10,12-tetrahydro-4,12;6,10-diethanoanthracene[2,3-c;7,8-c′]dipyrrole and syn-4,7,11,14- tetrahydro-4,14;7,11-die…
Piezoelectric materials should have stable performance during electric cycling in service. Because piezoelectricity-related properties depend on the ferroelectric domain structure, it is essential to investigate the fatigue characteristics of domain structures under electric loading. Piezoresponse force microscopy (PF…
Abstract A novel method for the organic modification of a ceramic thermal conductive filler (α‐alumina) with cold plasma was developed for the preparation of elastomer thermal interface materials with high thermal conductivities and low moduli. The α‐alumina fillers were first coated with low‐molecular‐weight polydime…
We report a solution-based fabrication of perovskite multilayers and superlattices using perovskite nanosheets. Perovskite nanosheets (LaNb 2 O 7 , Ca 2 Nb 3 O 10 , and Sr 2 Nb 3 O 10 ) were prepared by delaminating layered perovskites. A layer-by-layer approach using Langmuir–Blodgett deposition was effective for fab…
Spalling and cratering are common modes of failure in concrete structures subjected to blast load detonations. There are limited data and models available on the prediction of the spalling/cratering of reinforced concrete members under blast loads. Currently engineers rely on empirical curves to assess the level of da…
As demand of high power density PMSM in EV and PEV application rises up, the cooling problems become highly valued. This paper introduces Aluminum Nitride (AlN) potting compound with high thermal conductivity into PMSM heat dissipation. Comparison test method and results are given.
Abstract Poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV)/phenolic blends are new miscible crystalline/amorphous polymer blends prepared via solution casting method in this work, as evidenced by the single composition dependent glass transition temperature. The measured Tgs can be well fitted by the Kwei equation w…
Nanotechnology for biomedical applications - enhancement of photodynamic activity by nanomaterials Over the last two decades nanotechnology has become one of the most dynamically evolving field of research. The unique properties of nanomaterials, not disclosing at microscale, are examined and exploited to extend our u…
It is known that a number of compressed melts undergo structural phase transitions. Data on the structural changes at high pressures in chalcogenides (AsS, As 2 S 3 ) and oxide (B 2 O 3 ) melts with a network structure have been reviewed. Viscosity is one of the fundamental physical properties of a liquid. For various…

This article considers the sandwich structures with aluminium (Al) foams of various thicknesses in conjunction with skins composed of fibre-metal laminates (FML). The FMLs with Al sheet and glass fiber reinforced polypropylene (GFPP) composites were integrated with Al foam for composing the sandwich panels. The FML–fo…
A methodology to design three-phase induction motors is presented. The procedure is based on a simple geometrical approach and self-consistent equations, without any use of empirical/corrective coefficients. In the proposed design tool, the machine geometrical dimensions are automatically computed starting from few de…
A new pyrrolidine derivative, 3-hydroxy-5-(hydroxymethyl)-4-(4'-hydroxyphenoxy)pyrrolidin-2-one (1), and eight known steroids, (22E,24R)-7beta,8beta-epoxy-3beta,5alpha,9alpha-trihydroxyergosta-22-en-6-one (2, a reassigned structure of (22E,24R)-5alpha,6alpha-epoxy-3beta,8beta,14alpha-trihydroxyergosta-22-en-7-one), (2…
Problem of Lattice Rotation Due to Plastic Deformation. Example of Rolling of f.c.c Materials Rotations of grain crystal lattice are responsible for texture formation during plastic deformation. The classical definition of lattice rotation leads in some cases to different texture predictions than the definition based…
Influence of membrane material and pore size on the performance of a submerged membrane bioreactor (sMBR) for oily wastewater treatment was investigated. The sMBR had a working volume of about 19 L with flat sheet modules at the same hydrodynamic conditions. Five types of micro- and ultra-polymeric membranes containin…
Electrospraying is a method of generating fine mist through electrostatic charging. It is a versatile method based on electrohydrodynamic process for forming small droplets. These droplets are highly charged. This prevents droplet coagulation and promotes self-dispersion which results in uniform coating on the target…
This paper details a technique for achieving dual-band operation from a ring type slot frequency selective surface (FSS). Series resonant tuned circuits are employed in the structure to operate as frequency selective switches, offering a high or low impedance state depending upon the operating frequency of the FSS. A…
