The syn-atropisomers of the title bis(tertiary amide)s were designed as six-bladed molecular propellers based on the "directing effects" of amide dipoles; the helicity of the propeller is biased to prefer one handedness upon the attachment of point chirality to the amide nitrogens to attain stronger circular-dichroism…
Various kinds of field-effect transistor (FET) have been fabricated with C 60 nanowhisker (NW) and also studied for nano-electronics application. Especially, pure and solvated C 60 NWs have been synthesized in N 2 environment so as to clarify the best device performance of C 60 NW-FET. The FET works not only under vac…
Dyes of characteristically different composition have been tested with respect to long‐term stability in operating standardized dye sensitized cells during a time period of up to 3600 hours. Selective solar illumination, the use of graded filters, and imaging of photocurrents revealed that degradation is linked to the…
Isothermal heat treatment was performed for austenitized Cu bearing eutectoid steels (Fe–0.8%C–Cu alloys). Microstructural observations revealed that the pearlite transformation is significantly retarded by the addition of Cu, but the morphology of pearlite, such as lamellar spacing and block size, are hardly influenc…
This report described a new float-polishing technique with large clearance utilising a newly developed magnetic responsive fluid, Magnetic Compound Fluid (MCF) developed by one of the authors, Shimada, in 2001. Before the present study, a clearance of up to 0.1 mm had been obtained through the use of MCF in float poli…
Via imaging ellipsometry, we study the phase transition dynamics induced by selective gelation of one component in a binary supported phopholipid bilayer. We find the modulation of two attendant morphological features: emergence of extended defect chains due to a net change in the molecular areas and fractal-like doma…
A microscopy probe designed for use in high field magnets is presented. It was developed to observe and continuously measure the position and shape of a magnetically driven grain boundary in a magnetically anisotropic material. The approach utilizes the anisotropy of reflectivity of visible light for orientation contr…

The peculiarities of plasma treatment of agglomerated (spray dry) YSZ powder and subsequent plasma spraying of produced HOSP powder (consisting of the hollow spherical particles) are analyzed. Formation of splats of hollow YSZ droplets deserves a special attention within thermal spraying. In this case, immediately pri…
The present investigation studies the processing of A356 Al-Si alloy containing up to 5% vol.-% nano-sized al2o3 particles having size less than 500 nm. Composites were prepared using semi-solid casting route. To evaluate the results the alloys were further characterised by various metallurgical and mechanical charact…
Torsion of the greater omentum is an uncommon cause of acute abdominal pain that mainly affects adults in their fourth or fifth decade. It can be primary or secondary due to rotation of a mobile omental segment around a pivotal point or a pathologic intraabdominal process (e.g. inguinal hernia). The clinical features…
Naparticles of cobalt-manganese oxide were prepared by chemical co-precipitation method by decomposition of their respective metal chlorides, sodium carbonate and ethylene diamene tetra acetic acid (EDTA). The heal treatment of the ground precursor powders at their respective decomposition temperature and beyond, resu…
Summary: The present study tests and uses the LS-DYNA explicit solver to replicate explosive tests of reinforced concrete slabs subjected to various charge weights of TNT close-in explosions. The numerical model includes slab (with rebar), immediate ambient air, supporting timbers, and TNT. Reinforced concrete slab wa…
The paper presents a new method for the analysis of the number of harmonics that must be considered in order to respect the European standards. One intends to verify if the limitations are correct for a series of real cases. Some characteristic features of the data acquisition system along with the most important prin…
In semiconductor copper (Cu) metallization, external organic additives including bis(3-sodiumsulfopropyl disulfide) (SPS) and polyalkylene glycols (PAG) are necessary and widely used to improve the gap-fill capability of Cu electroplating for high-aspect-ratio features. In this study, the interaction of SPS and PAG (S…
Reaction of Kpmf (pmf(-) = anion of N,N'-bis(pyrimidyl-2-yl)formamidine, Hpmf) with divalent copper salt CuX2 afforded the linear trinuclear complexes of the type [Cu3(pmf)4](X)2 (X = BF4, 1; NO3, 2; ClO4, 3), while reaction of Kpmf with monovalent copper salt CuX gave the linear tetranuclear complexes of the type Cu4…
Abstract Multiple conformational states in heterochiral diproline sequences have been characterized in the solid state by the determination of the crystal structures of seven tripeptides in enantiomeric and racemic forms. The sequences of the type Piv‐DPro‐LPro‐DXxx‐NHMe (D‐L‐D) [DXxx = DVal 1, DLeu 3, and DPhe 5] and…
In the present study, an attempt is made to synthesize Al—Si alloy—SiC particle reinforced composite using liquid metallurgy route and to characterize the composites in terms of microstructure, mechanical properties, and sliding wear behaviour. The composite shows uniform distribution of SiC particles and good interfa…
This article discusses challenges to the supply chain in today's steel industry. In the steel industry, the supply chain, apart from actual production, is an extremely complex task, requiring the consideration of numerous factors and objectives. Sharply fluctuating demand, raw materials supply and uncertain prices pro…
Gadolinium neutron capture therapy (Gd-NCT) is a promising approach to fight cancer. One key factor for the success of Gd-NCT is to deliver and maintain a sufficient amount of Gd inside tumors. A large amount of Gd can be readily introduced into tumors by direct intratumor injection. However, an innovative approach is…
