Nitrogen-rich 1,2,4-triazole (1) and 1,2,3-triazole (2) react as bases with the oxygen-rich acids HNO3 (a), HN(NO2)2 (b), and HClO4 (c) to produce energetic salts (1a, 1b, and 1c and 2a, 2b, and 2c, respectively) potentially applicable to composite explosives and propellants. In this study, these salts were studied wi…
Abstract The permeability and stability of Sm 0.7 Sr 0.3 CoO 3− δ (SSCO) regarding the special requirements for carbon capture and storage (CCS) application were investigated. Pure CO 2 was used as the sweep gas at 900 °C, leading to that the oxygen permeation flux decreases by about 34 %. Several cycles of changing t…
The traditional gold mining in Cempaka, Banjarbaru, South Kalimantan, Indonesia used mercury in order to separate the gold with a fine sand and rocks. Mercury can impair the function of the cellular and organism physiology that live in the mining sites. In cellular on earthworm may adapt to help in repairing cell dama…
Unconventional computing is an area of research in which novel materials and paradigms are utilised to implement computation. Previously we have demonstrated how registers, logic gates and logic circuits can be implemented, unconventionally, with a biocompatible molecular switch, NitroBIPS, embedded in a polymer matri…
The aim of work is to define the distribution density of winding yarn on cylindrical and conical bobbins. It is known that parallel winding gives greater density and more regular distribution, but the unwinding of yarn is much more difficult for following process. The conical spool has an enormous advantage during unw…
На підставі розробленої технології автоматизованого лазерного зварювання плоских трубок з мідно-нікелевих \nсплавів спроектовано і створено технологічне оснащення лазерного зварювального комплексу, яке може бути впровадженим на підприємствах машинобудівної, авіакосмічної, суднобудівної або автомобілебудівної промислов…
ABSTRACT A new method to prepare low melting point polyamide‐6 (LPA6) by complex reaction of calcium chloride (CaCl2) and polyamide‐6 (PA6) in a co‐rotating twin screw extruder was reported. We employed a new rheological method to study the crystallization behavior of PA6/CaCl2 complex and the mechanism of confined cr…
An amyloidogenic LAM-L peptide (AASIKVAVSADR, all-L configuration) derived from laminin promoted cell adhesion, neurite outgrowth, and angiogenesis. Here, we prepared novel matrices using double-stranded DNA and the LAM-L peptide. Double-stranded DNA promoted aggregation of amyloid-like fibrils and generated a LAM-L/D…
One of energy source alternative that can be used as a substitute for fossil fuel-based energy, is bioethanol. Bioethanol is biochemistry fluid from fermentation process of sugars from carbohydrate sources by using microorganisms. The raw material of bioethanol production is very diverse, like pineapple peel. Pineappl…
The coating of solid particles on the surface of liquid in air makes liquid marbles a promising approach in the transportation of a small amount of liquid. The stabilization of liquid marbles by polymeric latex particles imparts extra triggers such as pH and temperature, leading to the remote manipulation of droplets…
BACKGROUND: Guide-trees are used as part of an essential heuristic to enable the calculation of multiple sequence alignments. They have been the focus of much method development but there has been little effort at determining systematically, which guide-trees, if any, give the best alignments. Some guide-tree construc…
The absolute optical power at 611 nm emitting from Eu doped Gd2O3 nano phosphors upon X-ray excitation from a microfocus X-ray source operated at 100 kV was measured with thin film photovoltaic cells (TFPCs), whose optical response was calibrated using an He-Ne laser at 632 nm. The same TFPCs were also used to determi…
Nanosized‐layered rock‐salt LiVO 2 was prepared by a new method from peroxo‐polyvanadic acid. The X‐ray diffraction pattern was well fitted with the space group R −3 m in the Rietveld analysis and the crystallite size was estimated at 47 nm. The electrochemical properties as cathode materials for lithium ion batteries…
Magnetic and photoluminescent properties of ZnSe:Cr crystals were studied within 5–300 K temperature range. It was shown that, at chromium concentrations below 0.05 at. %, Cr ions form point substitutional defects, which exhibit ferromagnetic properties. As a result, the emission caused by radiative recombination of t…
Alzheimer disease (AD) is a progressive neurodegenerative disease leading to memory loss. Numerous lines of evidence suggest that amyloid-β (Aβ), a neurotoxic peptide, initiates a cascade that results in synaptic dysfunction, neuronal death, and eventually cognitive deficits. Aβ is generated by the proteolytic process…
The photoirradiation of a monoclonal antibody 1 (mAb1) at λ = 254 nm and λmax = 305 nm resulted in the sequence-specific generation of d-Val, d-Tyr, and potentially d-Ala and d-Arg, in the heavy chain sequence [95-101] YCARVVY. d-Amino acid formation is most likely the product of reversible intermediary carbon-centere…
This study was designed to evaluate the SERI Surgical Scaffold, a silk-derived bioresorbable scaffold, in an ovine model of two-stage breast reconstruction. Sheep were implanted bilaterally with either SERI or sham sutures during the stage 1 procedure. The SERI group underwent an exchange procedure for a breast implan…
Abstract Cancer is one of the leading causes of death; with it may different types, it kills thousands of people every day. Various types of treatment have been developed to treat and cure cancer. Nanotechnology has emerged as one of the most fruitful areas of science in cancer treatment and the nanomaterials are cons…
Abstract Aluminum and magnesium were joined through diffusion bonding using Ni interlayer. The microstructure and mechanical performance of the Al/Ni/Mg joints at different temperatures was investigated by means of scanning electron microscope (SEM), electro‐probe microanalyzer (EPMA), X‐ray diffraction (XRD), Vickers…
Abstract The flotation and surface interaction of rutile with nonyl hydroxamic acid were investigated in this work. The results show that the adsorption density and flotation recovery of rutile have similar tendency, especially the maximum recovery and adsorption occur at pH about 7.5. In terms of Fourier transform in…
