The cyanobacterial cytochrome b(6)f complex is central for the coordination of photosynthetic and respiratory electron transport and also for the balance between linear and cyclic electron transport. The development of a purification strategy for a highly active dimeric b(6)f complex from the thermophilic cyanobacteri…
The main effort of each technological process is not only to reduce the costs, but also to reduce the impact on the environment. The technology of abrasive water jet is one of the methods of division and cutting materials with the lowest impact on the environment, since water is the cutting tool, in our case with the…
Wearable devices are arguably one of the most rapidly growing technologies in the computing and health care industry. These systems provide improved means of monitoring health status of humans in real-time. In order to cope with continuous sensing and transmission of biological and health status data, it is desirable…
The strengthening effect and uniformity of residual stress and strain of 7075-T6 aviation aluminum after laser shock peening were investigated. The finite element simulation model of laser shot peening on 7075-T6 aviation aluminum alloy was established and verified. On this basis and combined with experiment, the micr…
The structure formation of yttria stabilized zirconia - nickel oxide composites sintered in air and argon atmosphere were studied. It was shown that the crack propagation in 3Y-TZP ceramics greatly inhibited by creation of composite structure by addition of NiO particles and sintering at 1500 o C in argon atmosphere.…
Abstract The μ‐η2:η2‐peroxodicopper(II) core found in the oxy forms of the active sites of type III dicopper proteins have been a key target for bioinorganic model studies. Here, it is shown that simple bis(oxazoline)s (BOXs), which are classified among the so‐called “privileged ligands”, provide a suitable scaffold f…
SnO2-based electrodes for lithium ion batteries (LIBs) typically exhibit high initial specific capacity but poor cycling performance. A possible strategy to improve the cycling performance is to prepare nanocomposites containing SnO2. Here we demonstrate a straightforward method to prepare composites containing SnOx a…
Low-voltage swing (≤1.0 V) high-contrast ratio (6 dB) electro-absorption modulation covering 1460 to 1560 nm wavelength has been demonstrated using Ge/SiGe quantum confined Stark effect (QCSE) diodes grown on a silicon substrate. The heterolayers for the devices were designed using an 8-band k.p Poisson-Schrödinger so…
Micrometric particles of Ag3PO4 were prepared by a simple precipitation method, and the as-prepared material was characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FEG-SEM), nitrogen sorption isotherms, Raman spectroscopy and UV-visible diffuse reflectance spectrophotometry. Ag3PO4…
Abstract (4S)‐Aminoproline is introduced as a pH‐sensitive probe for tuning the conformational properties of peptides and proteins. The pH‐triggered flip of the ring puckering and the formation/release of a transannular H bond were used to switch the formation of collagen triple helices on and off reversibly.
Ultrasonic impact treatment (UIT) is a remarkable post-weld treatment, which reduce not only in external stress concentration, but also in residual stress in a welded joints. Internal and surface stresses were investigated on UIT treated welded joints by neutron and X-ray diffraction method. This paper discuses the ef…
Abstract Uniaxial tension tests and hole-expansion tests were carried out to determine the influence of silicon on the microstructures, mechanical properties, and stretch-flangeability of conventional dual-phase steels. Compared to 0.03wt% silicon, the addition of 1.08wt% silicon induced the formation of finer ferrite…
We studied Cu self-dynamics and liquid density of Zr 66.7 Cu 33.3 , Zr 35.5 Cu 64.5 , Zr 36 Cu 64 , and Zr 38.2 Cu 61.8 liquids using a combination of containerless processing techniques and quasielastic neutron scattering. We show that the composition dependence of the Cu self-dynamics is qualitatively controlled by…
Molecular self-assembly is a versatile nanofabrication technique with atomic precision en route to molecule-based electronic components and devices. Here, we demonstrate a three-dimensional, bicomponent supramolecular network architecture on an all-carbon sp(2)-sp(3) transparent platform. The substrate consists of hyd…
Cu(In1−xGax)Se2 (CIGS) alloy based thin film photovoltaic solar cells have attracted more and more attention due to its large optical absorption coefficient, long term stability, low cost and high efficiency. However, the previous theoretical investigation of this material with first principle calculation cannot fulfi…
Abstract Carbonate ores of cobalt are a significant but under-recognized fraction of the global Co resource. Cobalt forms spherocobaltite (CoCO 3 , calcite group), whose complete solid solution with isostructural magnesite, MgCO 3 , is described here for the first time. Cobalt-rich dolomite, Ca(Mg,Co)(CO 3 ) 2 , and C…
Abstract Trehalose dihydrate is a nonreducing disaccharide which has generated great interest in the food and pharmaceutical industries. However, it is well recognized that considerable batch to batch variation exists for supposedly identical samples, particularly in terms of the thermal response. In this investigatio…
A series of new monomers containing dialkyl anthracene maleimide derivatives [4a,b(I–V)], which can be used as a precursor of a polymer of intrinsic microporosity (PIM) has been synthesized and characterized successfully. The homopolymers prepared via polycondensation with 2,3,5,6,-tetrafluoroterephthalonitrile (TFTPN…
Abstract The addition of multi‐walled carbon nanotubes (MWCNTs) to enzymatic electrodes based on either glucose oxidase (GOx), or an oxygen‐insensitive flavin adenine dinucleotide‐dependent glucose dehydrogenase (FADGDH), increases the amount of {Os(4,4′‐dimethyl‐2,2′‐bipyridine)2[poly(vinylimidazole)]10Cl}Cl redox po…
A comparative investigation was carried out with electrodeposited Ni-W and Ni-Mo-W coatings to evaluate the influence of Mo content on the corrosion resistance. Corrosion tests were carried out by potentiodynamic linear polarization, electrochemical impedance spectroscopy and open circuit monitory, in NaCl solution. N…
