The article is devoted to analysis of tendencies and advanced technologies in the field of energy supply and energy efficiency of tall buildings, to the history of the emergence of the concept of "efficiency" and its current interpretation. Also the article show the difference of evaluation criteria of the leading rat…
Differential thermal analysis (DTA), X-ray diffraction (XRD), and electromotive force (EMF) are used to triangulate Ag–In–Te–I(Br) systems in the vicinity of compounds AgIn 2 Te 3 I and AgIn 2 Te 3 Br. The three-dimensional position of the AgIn 2 Te 3 I–InTe–Ag 2 Te–AgI and AgIn 2 Te 3 Br–InTe–Ag 3 TeBr phase areas wi…
The deposition and dissolution of sodium superoxide (NaO 2 ) was investigated by atomic force microscopy.
Based on ab initio total energy calculations, we predict the atom location of the third element X (X = Sc, Ti, V, Cr, Mn, Fe, Co, Ni and Cu) in B2-type TiNi. The formation energy of Ti-substitutional X and Ni-substitutional X are estimated by using the Vienna Ab initio Simulation Package (VASP). It is found that Sc pr…
La2O3/graphene oxide (GO) nanocomposites were simply synthesized from commercially available LaCl3·7H2O and multilayer GO (5–10 layers) in N,N-dimethylformamide (DMF) under reflux condition without extra stabilizer. The characterization results of scanning electron microscopy (SEM), transmission electron microscopy (T…

The anchoring technology is extensively applied in reinforcing protection of the earth relics. Now that no specification is available for different new anchor rods in earth relics protection due to diversified destruction modes of earth relics and complexity of engineering technology conditions, it is urgent to guide…
A new method for quantitative description of the degree of similarity of coordination polyhedra has been proposed. The results of studying the five-coordination polyhedra of the antimony and bismuth complexes, in which the nearest coordination environment of metals consists of only oxygen and carbon atoms, have been p…
Magnesium nitride (Mg 3 N 2 ) is prepared via lyotropic phases with liquid ammonia (lq-NH 3 ). To avoid oxide contamination, the synthesis was performed in the absence of any oxygen source ( e.g. , solvents, starting materials and surfactants).
This work describes tin-induced crystallization of amorphous silicon studied with Raman spectroscopy in thin-film structures Si-Sn-Si irradiated with pulsed laser light. We have found and analyzed dependencies of the nanocrystals’ size and concentration on the laser pulse intensity for 10 ns and 150 μm duration laser…
In our previous study, a cone-shaped rotating disk had been designed and proposed for generating shear force on the cell in a cell culture plate. This study aims to improve the design of the rotating disk that could provide a better uniformity of shear stress distribution. The top of the cone was designed to be trimme…
The work reported in this paper aims at a better understanding of the magnetic doping effects on the structural and electrical properties for a series of YBa2(Cu1-xCox)3O7-δ ceramics. The Co doped YBa2Cu3O7-δ are (YBCO) prepared by conventional solid state reaction method and characterized by X-ray diffraction (XRD) a…
Solubilities, densities, and refractive indices in the quaternary system (Li 2 B 4 O 7 + Na 2 B 4 O 7 + Mg 2 B 6 O 11 + H 2 O) at T = 298.15 K and p = 0.1 MPa were investigated experimentally with the method of isothermal dissolution equilibrium. According to the experimental data, the phase diagrams and the diagrams…
This paper presents the application of two different control methods of Hybrid Fuzzy-PI and PSO-PI controllers for the active power filter (APF) in order to compensate the harmonics and reactive power under different load conditions. Firstly, the particle swarm optimization (PSO) is used for determining the optimal va…
In the history of mankind, it is feasible to find clothing and medical uses of plants. Metals from bulk to nano proportions were also somehow always present. Uses of metallic nanoparticles have been increasing over the years in applications such as textile industry, remarkably the silver ones. The standard silver nano…
The control of structure formation in the active layers of organic solar cells allows for improvement in their processability and enhancement of the efficiency of the final devices. In the present work, in situ studies of film formation from binary toluene solutions of an electron donor, poly(3-hexylthiophene) (P3HT),…
The use of RNA macromolecules as therapeutic agents for HIV and other infectious diseases is promising but limited by suboptimal delivery to the target site. With HIV infection, this is particularly challenging since lymphocytes are particularly difficult to transfect. This paper describes an innovative strategy for t…
The drying curves of pullulan, alginate, and blend films at 40, 50 and 60°C were investigated using gravimetric methods. Several mathematical models available in the literature were fitted to the experimental data. The Midilli- Kucuk model satisfactorily described drying kinetics of tested films with the highest R2 an…
Requirements to advanced engines for civil aviation are discussing. Some significant problems of ensuring reliability of advanced gas turbine engines are mentioned. Special attention is paid to successful utilization of new materials and critical technologies. Also the problem of excluding failure of engine part due t…
Ultrasonic impact treatment (UIT) is currently used in several manufacturing processes. UIT is a process in which ultrasonic vibration is used to impact pins onto a metal surface. To clarify the mechanisms of deep compressive residual stress in UIT, the effects of the pin tip radius on residual stress distributions we…
