It is established via an X-ray method that the preparation of powdered forms of cellulose under the action of Lewis acids on fibrous hardwood cellulose is accompanied by a change in its crystallographic characteristics. The degrees of crystallinity, the sizes of crystallites, and the periods and monoclinic angles of t…
Crater-like Taylor cone electrospinning is a novel, simple, and powerful approach to mass produce nanofibers. The Taylor cone, crater-like liquid bump on the free liquid surface, in this electrospinning process plays a key role to produce multiple fluid jets which finally solidifies nanofibers. A multi-physics coupled…
Ever increasing energy consumption and pollution caused by burning of fossil fuels to meet our energy requirements have led researchers to focus on alternate forms of energy which are clean. Solar, wind and fuel cells are the areas in which research is going on with fast pace. Solar and wind have their drawbacks since…
{[Ln2(PDOA)3(H2O)6]∙2H2O}n (Ln = Gd, 1; Ln = Ce, 2; H2PDOA = o-phenylenedioxydiacetic acid) has been synthesized and characterized by chemical analyses, IR spectroscopy, and thermal analyses. Single-crystal X-ray structure analyses revealed that both 1 and 2 are polymeric and built up of a ladder-like arrangement of L…
A new technique for the synthesis of porous silicon layers with silver nanoparticles has been proposed which is based on the high-dose low-energy implantation of crystalline silicon with metal ions. In order to demonstrate this technique, in this work we implanted a polished wafer of monocrystalline silicon Ag + -ions…
Abstract This article contains information concerning of the analysis the possibility of defining refinery qualities of the slag based thermo-physical and thermo-dynamical data. It was showed the brass refining with the many-carbide reagents introduced in to the slag. The paper presents the results of the structure an…
We review the appearance of Slater-Pauling rules in half-metallic magnets. These rules have been derived using ab-initio electronic structure calculations and directly connect the electronic properties (existence of minority-spin energy gap) to the magnetic properties (total spin magnetic moment) in these compounds. T…
In the last three decades, due to the unique structure and biological activities of fullerene materials, many reports were published on their synthesis and application in biomedical and environmental sciences, however, there is very few examples that have leapt out of the laboratory and into the commercial market. Obv…
Molecular dynamics simulations are performed to investigate the influence of irradiation damage on the mechanical properties of copper. In the simulation, the energy of primary knocked-on atoms (PKAs) ranges from 1 to 10 keV, and the results indicate that the number of point defects (vacancies and interstitials) incre…
Carboxymethyl chitosan (CMC), one of the most important chitosan derivatives, is synthesized by alkalization of chitosan, followed by carboxymethylation. CMC has higher moisture absorption and moisture retention, higher chelating and sorption abilities as well as better biological properties than chitosan. Polymeric n…
The Photovoltaic properties of dye co-sensitized solar cells fabricated by using a one-bath mixed dye solution were compared with those of mono-sensitized devices. Co-sensitized TiO2 photo-electrodes were prepared from a mixed dye solution of M-Red [2-cyano-3(10-hexthyl-phenothiazin)acrylic acid] or D-Red [3,3′-hexyl-…
The space charge behaviors of oil-paper insulation affect the stability and security of oil-filled converter transformers of traditional and new energies. This paper presents the results of the electrical aging of oil-impregnated paper under AC-DC combined voltages by the pulsed electro-acoustic technique. Data mining…
Epithelial ovarian cancers are a group of at least five histologically and clinically distinct diseases, yet at this time patients with these different diseases are all treated with the same platinum and taxane-based chemotherapeutic regimen. With increased knowledge of histotype-specific differences that correlate wi…
The objective of this research is to utilize the ultrasonic method to analyze the property of partial discharge (PD) which is generated by the winding of the insulation stator in the generator. Therefore, a PD measurement system is built based on ultrasonic and virtual instruments. Three types of PD models (internal P…
The effect of alkaline treatment of two basal liquation sodium borosilicate porous glasses on their micro- and mesoporous substructures has been studied. The morphology of pores has been investigated and the structural characteristics of micro- and mesoporosity have been determined by the equilibrium and kinetic adsor…
As the demand for power consumption increases with an expanding global economy, the need for innovative solutions to meet the cooling demands of next generation servers looms large. Particular attention must be paid to ensuring that cooling mechanisms employed are not only efficient from a power consumption perspectiv…
Spent FCC catalyst is a waste from the petrochemical industry which has excellent pozzolanic properties, containing more than 90% silica and alumina. Its similarity to metakaolin creates interesting prospects for its use in the production of alkali-activated binders. In this study, the alkali activation of this residu…
A method of preparing nanosized titanium dioxide by gaseous detonation by using ethanol, hydrogen, and oxygen as an explosion source and titanium tetrachloride as a precursor is described. The results indicate that the rutile phase content of the obtained products is high, and the pure rutile phase can be produced by…
Natural fibres have recently raised attention for presenting adequate mechanical characteristics for the reinforcement of wood structural elements. The use of both natural fibres, in laminated beams and wood from reforestation, is in accordance with the current economic interest and sustainable appeal. This paper focu…
The failure of hydraulic turbine runners is a very rare event. Hence, in order to assess the reliability of these components, one cannot rely on statistical models based on the number of failures in a given population. However, as there is a limited number of degradation mechanisms involved, it is possible to use phys…
