Biddulphia rhombus var. atlantica was erected by Frenguelli from waters of the South Atlantic Ocean. A revision of its syntype series was carried out with light microscopy, a lectotype was chosen and compared with the lectotype of Odontella rhomboides (= Zygoceros rhombus), and with the lectotype of Odontella rhombus…

Dehydration of the LiI · 3H 2 O crystal hydrate in vacuum has been investigated at 20–25°C. The decomposition of the LiI · 3H 2 O crystal hydrate in vacuum proceeds to monohydrate. During heating of lithium iodide monohydrate, evolution of water vapor is observed at 30–100 and 100–170°C. Above 200°C, evolution of mole…
The multicomponent refractory oxide system Zn2(TiaSnb)1 − x ZrxO4 (a + b = 1; a: b = 1: 5, 1: 4, 1: 3, 1: 2, 1: 1, 1: 0, 2: 1, 3: 1, 4: 1; x = 0−1.0; Δx = 0.05) has been studied by x-ray diffraction, using samples prepared by melting appropriate oxide mixtures in a low-temperature hydrogen-oxygen plasma. Two phases, b…

We’ve tested the platform in close cooperation with leading academic institutions. If you have any questions or you notice…
Focal conics consisting of an ellipse and a hyperbola in chiral smectic C liquid crystals aligned in surface‐stabilized cells of medium thickness (about 25 µm cell gap) were characterized in relation to the chevron structure by synchrotron X‐ray microdiffraction. The focal conic texture is embedded in the chevron stru…
This paper explores the effect of a liquid lithium curtain on fusion reactor plasma, such curtain is utilized as the first wall for the engineering outline design of the Fusion Experimental Breeder (FEB-E). The relationships between the surface temperature of a liquid lithium curtain and the effective plasma charge, f…
Nanosized tin whiskers and spheres 15 nm in diameter form on anodic aluminum oxide (AAO) templates via a two-step anodization. The driving force, residual stress released from the template at a high temperature, causes tin whiskers of uniform size to grow on AAO within a few minutes. Various thicknesses AAO templates…

A radiation hardened, high-performance, ferroelectric memory (FeRAM) with 2 Mb density has been designed to yield radiation characteristics useful for many satellite and space applications. The ferroelectric capacitor for each memory cell is inherently resistant to both TID and SEU effects. A design approach employing…
The corrosion inhibition efficiency of two oligomers, derived from glycolysed products of poly(ethylene terephthalate) with diethanol and triethanol amine, was measured from weight loss and electrochemical polarization techniques. The polarization curves indicate that these oligomers act as mixed-type inhibitors. The…
The Y2O3 addition to Mg-5Si alloys has a good modification effect on the primary Mg2Si. With 0.05% or 0.1% (mass fraction) Y2O3 additions, the primary Mg2Si begins to change from coarse dendritic shape (about 100μm) into small polyhedral shape and therefore the alloys exhibits sub-modified microstructure. With 0.2% Y2…

Composites were made with jute, cordenka and jute+cordenka by extrusion and injection moulding. The matrix material was Polypropylene (PP) and PP maleic acid anhydride grafted copolymer (MAPP) was used as coupling agents. The mechanical tests were performed. The hybrid composite of jute 25% and cordenka 75% showed the…
Most small GTPases, whether free or complexed to their effectors, diffract to 2.0 Å resolution or better. Here, the complex between a small GTPase and its effector was screened in the classic way using the sparse matrix method, and large single crystals were obtained. The crystallization range is wide, typically with…
Manganese (Mn) and copper (Cu) doping of ZnS nanowires was achieved by thermal evaporation of Mn, Cu doped ZnS nanopowders. Field emission scanning electron microscopy, and X-ray diffraction studies of the obtained ZnS nanowires demonstrate that the nanowires are single crystal structures and have diameters about 30-2…
The new thought for designing the multi-phase and multi-scale nanocomposites was proposed to improve the comprehensive mechanical properties. Multi-phase and multi-scale particles are added to the matrix, and one of the additives is nano-scale particle, thus the comprehensive mechanical properties can be improved by t…
Phase-pure (La0.9Sr0.1)(Ga0.7Fe0.3)O3 − y and (Sr1.8La0.2)(GaFe)O5.1 powders with the perovskite and brownmillerite structures have been prepared from salt solutions by sol-gel processing at temperatures from 570 to 870 K. Ceramic coatings up to 100 μm in thickness have been produced by applying suspensions of the sol…
Anodic aluminum oxide (AAO), typical material with a self-organized porous structure, has recently attracted due to its many potential technical applications such as magnetic, electronic, and optoelectronic device (Whitney et al., 1993 and Rahman and Yang, 2003). There is a great demand for highly ordered and patterne…
Quality control is essential to ensure product quality in the textile industry and the way of sampling can determine its effectiveness as the facts regarding the quality are derived from the inspection of the samples chosen. Such data can be used in the control charts to determine whether control is necessary at the d…
