Transient photocurrents are measured to clarify carrier dynamics in a series of bulk heterojunction solar cells that are composed of [6,6]‐phenyl‐C61‐butyric acid methyl ester (PCBM) and diketopyrrolopyrrole‐tetrabenzoporphyrin conjugates substituted by straight alkyl groups (Cn‐DPP‐BP), of which the device parameters…
The microstructure and toughness of tungsten inert gas (TIG) backing weld parts in low-pressure steam turbine welded rotors contribute significantly to the total toughness of the weld metal. In this study, the microstructure evolution and toughness of TIG weld metal of 25Cr2Ni2MoV steel low-pressure steam turbine weld…
High Resolution Image Download MS PowerPoint Slide The straightforward synthesis and photophysical properties of a new series of heteroleptic iridium(III) bis(2-arylimidazole) picolinate complexes are reported. Each complex has been characterized by nuclear magnetic resonance, UV–vis, cyclic voltammetry, and photolumi…
The accuracy of post-B3LYP functionals is analyzed using an open-shell database of Cu(II) dinuclear complexes with well-defined experimental values of the magnetic coupling constants. This database provides a sound open-shell training set to be used to improve the fitting schemes in defining new functionals or when re…
Although Ag-Pt system is crucial for several technological applications, investigations of the thermodynamic properties of this system are limited. In the present study, activity of silver at various temperatures in the platinum rich solid solution was measured by a solid electrochemical method and employing AgI as th…
In this work, the influence of strain rate on the anisotropy of the Ti6Al4V titanium alloy has been analyzed. Tensile tests of notched specimens were carried out in three loading orientations (0, 45, and 90) with respect to the rolling direction, using the servo-hydraulic testing machine and Hopkinson bar. Investigati…
The low‐energy electron beam irradiation (LEEBI) effect at 80 K on the optical properties of InGaN/GaN multiple quantum well structures has been studied. It is shown that the new emission band formed under LEEBI is related to quantum wells. At 80 K the total intensity of new and initial emission bands does not change…
BACKGROUND: It is well-recognized that injection of iodinated radiographic contrast media (CM) sometimes causes acute renal injury via multiple mechanisms, such as vasoconstriction, toxicity on glomerular endothelium and tubular epithelium and so forth. CASE PRESENTATION: A 51-year-old man developed acute renal injury…
The algae described in this paper appeared in enrichment culture from epiphytic mosses sample collected in southern Zabaikalie (Russia). This organism forms 2–8-celled and 3-dimensional packages of irregular shape. Vegetative cells are spherical, ellipsoidal and ovoid when solitary; cells with thin wall, thickening wi…
Historically plants have played an important role in medicine. Medicinal herbs are moving from fringe to mainstream use with a greater number of people seeking remedies. Through observation and experimentation, human beings have learnt that plants promote health. The use of these herbal remedies is not only cost effec…
The physical nature of solvent vapor annealing (SVA) treatment is quite straightforward, and its application is ideal in small molecule-based bulk heterojunction solar cells. It has been suggested to rapidly achieve high-performance small-molecule photovoltaics by alternating the blends to ideally connect the crystall…
The usage of medium‐voltage switchgear is more and more common in high altitude areas. Few relative standards about the selection of switchgear air gap in low air pressure conditions are currently available for referring. In this study, four different types of switchgear air gaps, as well as a typical rod‐plane gap, a…
The article considers the question of nucleation sites during phase transitions, which, even for thoroughly studied martensitic transformations, remains an essential one. Generality of shear nucleation and nucleation site for diffusion (normal) and martensitic transformations is discussed. Specific aspects of nucleati…
Two novel porphyrins, ZnP(SP)CNCOOH and ZnPCNCOOH, bearing cyanoacrylic acid as an anchoring group were synthesized. Porphyrin ZnP(SP)CNCOOH contains a π‐conjugated spacer (SP) for improved electronic communication between the dye and the TiO2 electrode. The spacer bears polyethylene glycol chains to prevent dye aggre…
In this paper, the effects of rolling reduction rates on the microstructure of the NM360/Q345R composite were studied. With the electron backscatter diffraction(EBSD) contribution, the microstructure evolution and recrystallization of the bonded interface were mainly analyzed at various reduction rates (30%, 50%, 70%…
A new synthesis route for the zeolitic imidazolate framework ZIF-4 using imidazolium imidazolate is reported. Additionally, the ionic liquid-derived material is compared to conventional ZIF-4 with respect to the powder X-ray diffraction pattern pattern, nitrogen uptake, particle size, and separation potential for olef…
Alumina rich fly ash (ARFA) has been regarded as the alternative to bauxite in China. Hydrochloric acid process could be favored for alumina extraction, necessitating calcination of aluminum chloride hexahydate (ACH). In this work, the TGA/DSC results of ACH were used to suggest calcination procedures. Two-step calcin…
The article presents the results of tests carried out on S355JR steel of ferrite-pearlite and ferrite-bainite microstructures. The strength properties and fracture toughness were determined. The critical value of fracture toughness was determined at the moment of crack initiation by measuring of the stretch zone width…
With a design guided by computational fluid dynamics (CFD), additively manufactured from base metals and coated with metal catalysts using cold spray technology or electroplating, catalytic static mixers are used to replace fixed bed columns in continuous flow reactors. We have shown their versatility in gas-liquid hy…
In this study, we investigate different technologies to measure the specific capacitances C8of Nb/Al-AlOx/Nb Josephson junctions. They involve measuring Fiske mode resonance in long Josephson junctions, superconducting quantum interference device (SQUID) resonance, and Josephson plasma resonance. We find a logarithmic…
