Abstract Based on the [2‐(2‐nitrophenyl)propoxy]carbonyl (nppoc) group, six new photolabile protecting groups ( 2, 8, 9b, 16b, 25b , and 26 ), each covalently linked to a 9 H ‐thioxanthen‐9‐one (Tx) unit functioning as an intramolecular triplet sensitizer, were synthesized. Linkers were introduced between the Me group…
Dissipative particle dynamics (DPD) was carried out to study systems containing gold atoms, organic ether (oligohydroquinonyl ether terminated with a thiol group) and organic solvents. The components in the simulated system are very different in size and chemical nature. Our simulation showed that the reproduction of…
In the initial soil formation processes of the Volcanogenous Regosols (Scoriacious) from Miyake-jima Island, Japan, the soil profile morphology showed a distinct formation of the A horizon, about 10 cm thick, over C horizons during a period of 125 years. Along with these soil formation processes under the primary succ…
Carbon nanocoils (CNCs) were synthesized by the catalytic pyrolysis of acetylene over a mixture of Fe and SnO 2 particles in a chemical vapor deposition (CVD) apparatus. The effects of reaction temperature, the composition of Fe and SnO 2 in the catalyst, and the ratio of acetylene (C 2 H 2 ) to helium (He) gas were e…
Abstract The review is devoted to a study of interface phenomena influencing advanced properties of nanoscale materials processed by means of severe plastic deformation, high-energy ball milling and their combinations. Interface phenomena include processes of interface defect structure relaxation from a highly nonequi…
The development of plasma facing components for next step fusion devices in Europe is strongly focused to ITER. Here a wide spectrum of different design options for the divertor target and the first wall have been investigated with tungsten, CFC, and beryllium armor. Electron beam simulation experiments have been used…
Abstract Segmented polyurethanes (SPUs) which were expected to yield non‐toxic degradation products were synthesized from lysine‐based diisocyanate (LDI), 1,3‐propanediol (PDO), and polycaprolactone diol (PCL). SPUs were synthesized via a standard two‐step prepolymer method. The hard segment fraction was changed in or…
Time-of-flight neutron powder data and synchrotron infrared absorption spectra were collected for katoite hydrogarnet [Ca 3 Al 2 (O 4 D 4 )3] at pressures to 9.4 and 9.8 GPa, respectively. The phase transition from space group Ia3d to I4̄3d was observed in the neutron spectrum at ~7.5 GPa, as indicated by the presence…
[reaction: see text] Soluble arylamide dendrons with flexible linkers, peripheral ester or carboxyl groups (R), and focal amino or halogen functionalities (F) were synthesized from aryl glycineamide (AG) building blocks. The AG blocks were prepared in high yields from trivial starting materials by Fischer's haloacyl h…
The effect of processing technique as well as the effect of oxidizing agent on the electrical properties of Mn 0 . 4 7 Zn 0 . 5 3 Fe 2 O 4 ferrite has been presented. The dc resistivity is improved by citrate precursor method as compared to normal ceramic method and it is further improved by the addition of H 2 O 2 (h…
Digital partial discharge (PD) diagnosis has become a state of the art, but computer aided procedures based on pattern recognition principles are negatively effected by on-site disturbances. The benefits and limits of expert diagnosis compared to machine intelligent systems are discussed. It is pointed out that a suff…
Carbon nanotubes (CNT) were grown on carbon fibres, both PAN‐ and pitch‐based, by hot filament chemical vapour deposition (HFCVD) using H2 and CH4 as precursors. Nickel clusters were electrodeposited on the fibre surfaces to catalyse the growth, and uniform CNT coatings were obtained on both PAN‐ and pitch‐based carbo…
Pressure-volume-temperature data, along with dielectric relaxation measurements, are reported for a series of polychlorinated biphenyls (PCB), differing in the number of chlorine atoms on their phenyl rings. Analysis of the results reveals that with increasing chlorine content, the relaxation times of the PCB become g…
A series of zinc porphyrin-quinone linked dyads [ZnP-CONH-Q, ZnP-NHCO-Q, and ZnP-n-Q (n = 3, 6, 10)] were designed and synthesized to investigate the effects of hydrogen bonds which can not only provide a structural scaffold to assemble donor and acceptor moieties but also control the photoinduced electron-transfer pr…
The technology of selective oxygen plasma etching is presented. It enables the evaluation of the state of pigment dispersion, as well as the distribution of other solid particles that are added in pigmented coatings for various functional purposes. The technology is based on the selective interaction of reactive gaseo…
Dispersions containing nanoparticles (nanofluids) are mixtures with unique properties, and their transport properties depend on the three-dimensional network or microstructure of the nanoparticles, which can be affected by various factors including shear stress, particle loading, and temperature. In this research, we…
Single-walled carbon nanotubes (SWNTs) were synthesized by chemical vapor deposition using Ar-ion laser irradiation as a source of heat. The circular area corresponding to the position of the laser spot in the growing process was characterized by Raman scattering spectroscopy and scanning electron microscopy. The resu…
This paper presents an efficient modeling technique for the derivation of the dispersion characteristics of novel uniplanar metallodielectric periodic structures. The analysis is based on the method of moments and an interpolation scheme, which significantly accelerates the computations. Triangular basis functions are…
The effect of the selective adsorption of pig serum albumin as an antigen on the electrical properties of a carbon nanotube channel field effect transistor on which anti-pig serum albumin was immobilized as an antibody by physisorption in phosphate buffer solution has been investigated. We have succeeded in real-time…
Abstract We report the synthesis and characterization of a magnesium‐aluminum layered double hydroxide (LDH) containing[5,10,15,20‐tetrakis(4‐sulfonatophenyl)porphyrinato]cobalt( II )(CoTPhsP) by two routes: (i) CoTPhsP intercalation by structure reconstruction of the calcined pristine LDH [Mg 2.8 Al(CoTPhsP) int ] an…
