Aptamers, also known as chemical antibodies, are short single-stranded DNA, RNA or peptide molecules.These molecules can fold into complex three-dimensional structures and bind to target molecules with high affinity and specificity.The nucleic acid aptamers are selected from combinatorial libraries by an iterative in…
Effects of the milling time, annealing temperature and vial rotation speed were investigated on the formation of MoSi2–CrSi2 nanocomposite powder. X-ray diffraction was used to characterise the milled and annealed powders. The morphological and microstructural evolutions were studied by scanning electron microscopy an…
The title compound, sodium disilver arsenatotrimolybdate, Na(0.93 (1))Ag(2.07 (1))Mo(3)AsO(13), was prepared by a solid-state reaction. In the crystal structure, isolated AsO(4) tetra-hedra share corners with groups of three edge-sharing MoO(6) octa-hedra. This arrangement leads to the formation of anionic (1) (∞)[Mo(…
Crystals of the langasite family are of interest as they are piezoelectric in different devices. The properties of these classes of crystals can be modified within certain limits by isomorphous substitution. Single-crystal neutron diffraction studies were carried out for LGT (La(3)Ga(5.5)Ta(0.5)O(14)), LGST (La(3)Ga(5…
Scribing wheel (SW) is an important tool for separating glass panels in thin‐film transistor liquid crystal display industry. In this study, unlike the traditional SW completely made of polycrystalline diamond (PCD) or cemented tungsten carbide (c‐WC), an alternative partially taking advantage of chemical vapor deposi…
In the title coordination compound, [Mn(2)(C(14)H(8)O(4))(C(2)O(4))(C(10)H(14)N(4))(2)](n), the biphenyl-3,3'-dicarboxyl-ate and oxalate anions, both situated on inversion centres, function in a bridging mode, linking the dinuclear Mn(II) atoms into wave-like layers. Each 1,1'-(1,4-butane-1,4-di-yl)diimidazole ligand…
4-Deoxy-4-fluoro-β-D-glucopyranose, C(6)H(11)FO(5), (I), crystallizes from water at room temperature in a slightly distorted (4)C(1) chair conformation. The observed chair distortion differs from that observed in β-D-glucopyranose [Kouwijzer, van Eijck, Kooijman & Kroon (1995). Acta Cryst. B51, 209-220], (II), with th…
Abstract In Japan, hemodialyzers are usually sterilized by γ irradiation. However, the polymer materials used in the dialysis membrane, such as polysulfone (PSf) and poly(vinylpyrrolidone) (PVP), undergo crosslinking or degradation on exposure to γ radiation. In the present study, we prepared PSf/PVP films (PVP conten…
Mapping of reciprocal space for Ia-type diamond single crystals with synchrotron radiation has uncovered a variety of diffuse scattering features, some of them have not been observed before. The main component of diffuse scattering in the form of diffuse rods corresponds to a set of platelets which join together block…
This paper reports, for the first time, observation of sassolite (crystalline B(OH) 3 ) formation in alkali borosilicate glass (BSG) powder due to hydration during aging. Correlation between hydration behavior, sassolite formation, and phase separation has been established and hydration‐resistant low‐alkali BSG powder…
We aimed to understand one of the fundamentals of how silica and copper surfaces are flattened on the molecular scale by the chemical mechanical polishing (CMP) method, which is used in the fabrication of semiconductors. In particular, we examined whether even pure water affects the properties of silica and copper sur…
The heat capacities of N -benzyloxycarbonyl- l -3-phenylalanine were measured by means of a fully automated adiabatic calorimeter over the temperature range from (79 to 395) K. A solid−liquid phase transition corresponding to the melting process was observed. The temperature, the molar enthalpy, and entropy of the pha…
Abstract Solder paste is the primary bonding material used in the assembly of surface mount devices in electronics industries. It generally has a flocculated structure, which may break-down on shearing and slowly rebuild at rest. The proper characterization of the time-dependent rheological behaviors of solder pastes…
The nucleation and detachment of grains from a chilling surface were observed in real time in a model NH4Cl solution system. The effects of vibration frequency and amplitude on the detachment behaviour and crystallographic morphology of grains were also studied. The results show that partial dendrite arms were broken…
Simulated body fluid‐induced nucleation and growth of octacalcium phosphate (OCP) on polyvinyl alcohol–hydroxyapatite (HA) hydrogels has been described and discussed in the present manuscript. Bulk mineralization of hydrogels is well reported in the literature for structural tissue engineering applications. However, a…
In the title dinuclear copper complex, [Cu(2)Cl(4)(C(29)H(34)N(6))]·1.5H(2)O, both Cu(II) ions are coordinated in a slightly distorted square-pyramidal environment in which the N atoms of the dipicolyl-amine group and a chloride ligand form the basal plane. The apical position is occupied by a second chloride atom. Th…
Abstract The effect of surface roughness on wetting behaviour and evolution of microstructure of two lead-free solders (Sn-2.625Ag-2.25Zn and Sn-1.75Ag-4.5Zn) on copper substrate was investigated. Both solders exhibited good wettability on copper substrates having rough surface and lower wettabilty on smooth surfaces.…
The title compound, cis-diacetonitrile[(1R,2R)-1,2-diaminocyclohexane-κ(2)N,N']platinum(II) dinitrate monohydrate, [Pt(C(2)H(3)N)(2)(C(6)H(14)N(2))](NO(3))(2)·H(2)O, is a molecular salt of the diaminocyclohexane-Pt complex cation. There are two formula units in the asymmetric unit. Apart from the two charge-balancing…
Full maximum entropy mobility spectrum analysis was carried out on the basis of temperature and magnetic-field-dependent Hall measurements to assess the transport properties of homoepitaxial metal organic vapor phase epitaxy zinc oxide layers. Two different conductivity channels were clearly identified and the channel…
The microstructure and mechanical properties of Mg–8Li–(1, 3)Al–(0, 1)Y alloys were studied. Y refines and spheroidises the microstructures of alloys, and it causes the decrease in α phase percentage. Blocky AlY exists in α and β phases. When Al content is 3 wt-%, AlLi and MgLi2Al form in β phase. The Al content solid…
