This paper reports a novel surface-enhanced Raman scattering (SERS)-active light waveguide method for ultrasensitive detection of a sample dissolved in a small volume of low refractive index liquid. The SERS-active light waveguide demonstrated in this study was constructed via the light-guiding silica capillary. The s…
For the improvement of the conversion efficiency of CdS/CdTe solar cells by applying the wavelength conversion properties, the spectroscopic studies of the fluorescent laser dye Rhodamine 6G (Rh6G)-doped into polyvinylbutyral (PVB) and polymethylmethacrylate (PMMA) were carried out. It was found that all the photolumi…
Abstract Based on advanced plasma deposition technology with both DC and RF plasmas DLR Stuttgart has developed a concept of a planar SOFC with consecutive deposition of all layers of a thin‐film cell onto a porous metallic substrate support. This concept is an alternative approach to conventionally used sintering tec…
A two-stage technology of compaction of ultrafine-dispersed diamonds (UDDs) is developed and successfully applied for ampoule-free sintering of dense UDD granules in lead under a pressure of up to 100 GPa. Standard strength tests of polycrystals (fractions 80/63, 125/80) thus obtained showed a wide spread in strength…
New, bent-core, polycatenar pyridine mesogens are described. Binding to silver(I) leads to complexes properly described as discotic.
Dye-like applications of antibiotics to silk produce infection-resistant materials for potential use in biomedical applications. Two antibiotics, doxycycline (doxy) and cipro floxacin (cipro), are applied under a variety of conditions to silk and to silk that has previously been hydrolyzed at 40°C for 20, 40, and 60 m…
Cambridge Structural Database (CSD) was screened in order to find intramolecular C−H···π interactions with a chelate ring of coordinated porphyrin. It was found 154 crystal structures with 244 intramolecular C−H···π interactions in transition metal complexes with derivatives of porphyrin. Comparison of interacting dis…
Abstract While existing solid oxide fuel cell (SOFC) technology has demonstrated much higher energy efficiency with minimal pollutant emission than the conventional technologies, the costs of the current SOFC systems are still prohibitive for broad commercialization. To be economically competitive, both the cost of ma…
Abstract The effect of neutron flux level is a longstanding concern for determining the applicability of test reactor data or high lead-factor surveillance data to the prediction of embrittlement in commercial reactor pressure vessels (RPV). However, as operating reactors reach higher fluences, the question of flux ef…
The effect of modifying detonation nanodiamond additives on the stress-strain properties of polymer nanocomposites is investigated using polysiloxane polyblock copolymers as an example. It is shown that the formation of a physical network of supramolecular structures (due to self-organization initiated by force fields…
The effect of chemical-mechanical modification (CMM) on the ζ potential and size distribution of nanodiamonds was studied. Results show a significant change in the functional groups on its surface after CMM treatment by the anionic surface modifier DN-10. The amount of hydroxyl groups decreases, and two peaks connecte…
The subpeak was first observed in glassy Fe−Al ribbons. The origin of the subpeak is not due to the system size, but it is consequence of the occurrence of local atomic structural order. The usual stability of undercooled liquids against crystallization is explained by means of local atomic structural order. Direct ex…
Tarkianite, a new mineral species of ideal composition (Cu,Fe)(Re,Mo)4S8, was recently discovered in sulfide concentrate from the Hitura Ni–Cu–PGE mine, Nivala, western central Finland. It is associated with pyrrhotite, pentlandite, valleriite, chalcopyrite, cubanite, mackinawite, chromite, and the PGE minerals sperry…
Abstract Summary: The hydrogenation of a copolymer of styrene and butadiene (SBR) catalyzed by Ru(CHCHPh)Cl(CO)(PCy 3 ) 2 was experimentally investigated within the temperature range of 120–160 °C, at P of 300–1 200 psi, and a catalyst concentration of 10–78 × 10 −6 M . Special attention was paid to minimizing the ca…
A broadband polarization switch consisting of an active twisted nematic liquid crystal cell and two passive uniaxial compensation films is analysed. The conjugate gradient method was used for optimizing the device parameters. Simulation results indicate that the polarization switch exhibits a broad bandwidth and high…
Some information on the history of dynamic synthesis of diamond in Ukraine is considered. Basic characteristics of ASM5 0.1/0 and ASM1 0.1/0 nanodiamond powders produced by static synthesis are described. The characteristics and surface properties of nanodiamond powders produced by detonation synthesis in Ukraine are…
Genome data as well as biochemical studies have indicated that--as a peculiarity within hyperthermophilic Archaea--Thermoproteus tenax uses three different pathways for glucose metabolism, a variant of the reversible EMP (Embden-Meyerhof-Parnas) pathway and two different modifications of the ED (Entner-Doudoroff) path…
In this letter we report a large experimental effort exploring the dynamics of poly(vinyl ethylene) on length scales covering Rouse dynamics and below. The results establish the simultaneous existence of a generic sublinear diffusion regime which underlies the α-process in addition to the Rouse process. Both regimes a…
The aqueous electropolymerisation process can be used for the production of primer coatings on metals. Recent studies have shown that such types of coatings are highly corrosion resistant. Further it is also shown that electropolymerisation coating with pigment is feasible. Besides, the use of polymers such as polyani…
Abstract Electrically and thermally conductive resins can be produced by adding conductive fillers to insulating polymers. Mechanical properties such as tensile modulus, ultimate tensile strength, strain at ultimate tensile strength, and notched Izod impact strength are also important and cannot be ignored. This resea…
