Various effects of electron correlation accompany molecular bond dissociation, which makes the efficient calculation of potential energy curves a notoriously difficult problem. In an attempt to reliably reproduce both absolute energies and shapes of the benchmark dissociation curves, calculations with the combined CAS…
Abstract Homogeneous alignment of a π -conjugated polymer, poly(2,5-bis(3-hexadecylthiophen-2-yl)thieno[3,2- b ]thiophene) (PBTTT-C16), was obtained by bar-coating method in thin film. The macroscopic direction of the main chain orientation, that tended to be parallel or perpendicular to the coating direction, strongl…
Red acid soil is generally distributed in humid tropical areas under high rainfall. The main constraint is usually the extremely low pH of the soil due to the very intensive leaching of the bases from the soil. At the same time, however, the soluble micro elements, such as iron, are high. This can cause plant toxicity…
The focus of this study is in the description of synthetic heme/copper/O 2 chemistry employing a heme-containing binucleating ligand which provides a tridentate chelate for copper ion binding. The addition of O 2 (−80 °C, tetrahydrofuran (THF) solvent) to the reduced heme compound (P ImH )Fe II ( 1 ), gives the oxy-he…
Herein, we describe the fabrication and characterization of carbonized disulfide core-crosslinked polymer dots with pH-cleavable colorimetric nanosensors, based on diol dye-conjugated fluorescent polymer dots (L-PD), for reduction-triggered paclitaxel (PTX) release during fluorescence imaging-guided chemotherapy of tu…
The efficient protection of electric power distribution networks against lightning discharges is a crucial problem for distribution electric utilities. To solve this problem, the great challenge is to find a solution for the installation of surge arresters at specific points in the electrical grid and in a sufficient…
Autonomous self-repairing properties can prolong the service life of materials. In this paper, galactomannan hydrogel with high mechanical strength was prepared by graft copolymerization of galactomannan with acrylamide and octadecyl methacrylate in aqueous solution. The microstructure, water absorption property, self…
We experimentally demonstrated the strain relaxation effect in uniform GaN/Al0.19Ga0.81N quantum wells on GaN nanocolumn (NC) arrays with various column diameters and periods created using the Ti-mask selective area growth technique. The photoluminescence (PL) emission from the GaN well layer was not affected by the p…
The Paton Welding Journal, 2019, №10. International Scientific-Technical and Production Journal «The Paton Welding Journal» «The Paton Welding Journal» has been published monthly since 2000 in English, ISSN 0957-798X. «The Paton Welding Journal» is a cover-to-cover English translation of the «Avtomaticheskaya Svarka»…
Natural light-harvesting complexes (LHCs) absorb a broad spectrum of sunlight using a collection of photosynthetic pigments whose spatial arrangement is controlled by a protein matrix and exhibit efficient energy transfer. We constructed a novel light-harvesting protein mimic, which absorbs light in the UV to visible…
Flower-like mesoporous sulfated zirconia nanosheets (SZNs) were developed by pyrolysis of in situ sulfated Zr-MOFs for the first time.
The present work investigated melt flow pattern and temperature distribution in the sump of aluminum billets produced in a hot-top equipped direct chilling (DC) caster conventionally and with ultrasonic irradiation. The main emphasis was placed on clarifying the effects of acoustic streaming and hot-top unit type. Aco…
Plasmonic resonator arrays have attracted a great interest as a platform to enhance light–matter interaction and have been examined for their applicability to various types of optical devices, such as sensors, light emitter, and photocatalyst, to name a few. In a plasmonic resonator array, localized and propagating pl…
Learning from the design concept of antibody–drug conjugates (ADCs), we attempted to construct siRNA conjugated polymer brush by attaching a multiple of siRNA to the units of poly(amino acids) [poly(lysine) derivatives] through an intracellular cleavable disulfide bond. Note that the disulfide linkage is stable at ext…
High-pressure X-ray diffraction measurements on the layered oxyhydrides Sr 2 VO 3 H and Sr 3 V 2 O 5 H 2 reveal that both compounds undergo a pressure-induced rock-salt to CsCl ( B 1– B 2) structural transition, similar to those observed in binary compounds (oxides, halides, chalcogenides, etc.). This structural trans…
-prenyltransferase complex, synthesizing the glycosyl carrier precursor for N-linked protein glycosylation. Consistent with the important role of N-glycosylation in protein biogenesis, DHDDS mutations result in human diseases. Importantly, DHDDS encompasses a C-terminal region, which does not converge with any known c…
Behavioral assessment, such as systematic scoring or biomechanical measurement, is often used to evaluate the extent of the damage and the degree of recovery after spinal cord injury. However, the use of these methods in standardized evaluation is limited because they are subjective and require complex test systems to…
This article investigates the effect of mechanical bending strain on the electrical performance and gate-bias stability of flexible p-type tin monoxide (SnO) thin-film transistors (TFTs). The on-polyimide SnO TFTs have an inverted-staggered structure with a back channel passivated by SiNxand HfO2layers. The as-fabrica…
This paper is a conduct of experimental tests to investigate different effective parameters of a UNS C10100 copper/aluminum 1100 spring-back on a two-layer L-die bending sheet through finite element simulations. The parameters are the radius and clearance of die, sheet length, thickness of each layer, different lay up…
In this study, a novel phthalonitrile monomer containing pyrimidine ring, 4,6‐bis[3‐(3,4‐dicya‐ nophenoxy)phenoxy]pyrimidine (BCPM), was successfully synthesized by nucleophilic substitution reaction with resorcinol, 4,6‐dichloropyrimidine and 4‐nitrophthalonitrile. The BCPM monomer was cured by different temperature…
