Tomato purees were produced from De Rica and Roma cultivars of tomato, packaged in high density polyethylene and stored at ambient temperature (32±2 ºC). The stored purees were analysed weekly for physicochemical composition, sensory attributes and microbial load until they became unwholesome. There was a significant…
The catalytic performance of MoVMnW mixed oxides was investigated in the oxidative dehydrogenation of ethane at three different reaction temperatures (235, 255, and 275°C) using oxygen as an oxidant. The catalysts were characterized by using X-ray diffraction, temperature-programmed reduction, and scanning electron mi…
Three surfactants, with the same long alkyl tail but varying in functional groups, were selected to modify two pristine clays with different cation exchange capacities (CEC). Each of the modified clays was melt-mixed with polypropylene (PP) to prepare nanocomposites. The microstructure of the resultant nanocomposites…
Polymethylmethacrylate (PMMA) is one of the most studied polymers in the last years due to its outstanding mechanical and physical-chemical properties. This material is used in various applications in which it can be subjected to different constraints. In this work, PMMA samples were submitted to thermal treatment (at…
In the centrosymmetric dinuclear title compound, [Pd2(C4H7)2(C16H14N2S2)], the metal atom is η(3)-coordinated by three C atoms of a crotyl ligand [Pd-C = 2.147 (4), 2.079 (5) and 2.098 (5) Å], the longest distance influenced by the steric inter-action with the benzyl substituents of the di-benzyl-dithio-oximidate (DTO…
Abstract In this study, the friction and wear properties of A356 alloy processed via semi-solid casting and conventional casting were experimentally investigated. Experimental results indicate that under the same experimental conditions the wear of the semi-solid cast A356 in mass does not exceed 85 % of that of the c…
Abstract In this study we investigated the microstructural changes after a variety of heat treatments of the quasicrystalline Al–Mn–Be–Cu alloy. In addition, we report on Vickers microhardness measurements and tensile-test results for the same materials. The samples were produced in a conventional manner, i. e., melti…
The crystallization and preliminary X-ray diffraction analysis of the carbohydrate-binding module (CBM) from laminarinase Lic16A of the hyperthermophilic anaerobic bacterium Clostridium thermocellum (ctCBM54) are reported. Recombinant ctCBM54 was prepared using an Escherichia coli/pQE30 overexpression system and was c…
Solution combustion synthesis (SCS) is a well-known method for fabrication of different materials such as oxides and composite materials in an extensive range. In this investigation, solution combustion synthesis is used for fabrication of Ni-10 wt% Al2O3 nanocomposite. Nickel and aluminum nitrates, urea, and distille…
Lateral Force Microscopy (LFM) was used to probe the quality of binary mixed monolayers formed on planar polycrystalline gold through an electrochemical method. In the approach, portions of a self-assembled monolayer (SAM) composed of 2-aminoethanethiol (AET) were removed from the Au(111) surface facets by selective r…
Self-assemblies of Co(II) or Zn(II) salts with 1-((benzotriazol-1-yl)methyl)-1H-1,3-imidazole (bmi) and 1,4-benzenedicarboxylic acid (1,4-H2bdc) gave rise to two new isostructural complexes, [Co(bmi)2(bdc)]n (1) and [Zn(bmi)2(bdc)]n (2). Single-crystal X-ray diffraction determination shows that both complexes possess…
A new monochromator called an extra-focus constant-included-angle varied-line-spacing (VLS) cylindrical-grating monochromator (extra-focus CIA-VCGM) is described. This monochromator is based on the Hettrick-Underwood scheme where the plane VLS grating is replaced by a cylindrical one in order to zero the defocus at th…
We consider theoretically a composite chain consisting of a multiferroic helimagnet coupled to a conventional ferromagnet and inspect the conversion of electromagnon excitation into spin waves and vice versa. We demonstrate an electric-field control of spin-wave injection realized by electrically exciting an electroma…
BACKGROUND: Proteins are composed of domains, protein segments that fold independently from the rest of the protein and have a specific function. During evolution the arrangement of domains can change: domains are gained, lost or their order is rearranged. To facilitate the analysis of these changes we propose the use…
Made analysis of special peculiarities and regularities of reactions of titanium carbide, alloyed on metalloid sub lattice (N, O) with nickel melt. There was established that partial replacement of carbon in TiC on nitrogen decreases velocity of it dissolution in nickel, and increases degree of incongru- ence of proce…
Msmeg_0515, a gene from Mycobacterium smegmatis strain 155 encoding the ligand-binding domain, AgaE, of a putative ABC sugar transporter system, has been cloned into a pET-28a vector system, overexpressed in Escherichia coli and purified. The truncated protein lacking the first 27 residues, which correspond to a N-ter…
Abstract: Computational chemistry can be used for the prediction of photochemical reactivity and the design of photosensitizers for cancer phototherapy. For example, the activity of a photosensitizer for DNA damage can be estimated from the calculation of the HOMO energy of the molecules. In general, DNA damage is med…
The three-dimensional 6-directional variable cross-sectional cone-shaped tubular braided fabric (6DCTBF) has been applied successfully as the components in aerospace craft. The application of cone-shaped tubular braided fabric requires the densification of a small end to ensure ablation uniformity during composite fab…
With in situ electrical resistivity and Hall effect measurement, electrical transportation property and charge carrier behavior of ZnSe were investigated under high pressure using a diamond anvil cell (DAC). The electrical resistivity changed discontinuously at 7.7 and 11.9 GPa, corresponding to the phase transitions…
