The evolution of material design has mirrored advancements in the understanding of materials, nature, and the requirements of target applications. Originally, materials were only intended to play a passive role, but with a deepened understanding of material properties and design has come an improved ability to harness…
As the SiO2-based classical transistor reaches its scaling limit, a broad range of alternate dielectric materials are being explored for classical CMOS as well as other emerging technologies. These include high-k materials for gate dielectrics; low-k materials for interlayers; extreme high-k, ferroelectric materials f…
小径ボールエンドミル工具を用いた β 型チタニウム合金の ミーリング加工に関する研究A study on milling of β-type titanium alloy using small ball end mill tool
The last century has born witness to the rapid development of science and technology in the field of synthetic polymers. The growth rate of polymer technology is over than 10% in developed and developing countries. In the years ahead, 300-400 million tons of annual world production of polymer and usage of polymeric ma…
This paper presents an investigation of the influence of the Tribologist of Hardness control Aluminum nitride (AlN) films and Diamond Like Carbon (DLC) films on Al alloy substrates using Unbalanced Magnetron Sputtering (UBMS). The films were characterized by scanning electron microscope, dynamic ultra-micro hardness t…
SPS processing is extensively applied to the sintering of the powder materials because the characteristics of sintered materials can be improved remarkably. However, it is necessary to consider the deep reasons for the high performance due to SPS processing. In the present study, we introduce two typical results on th…
The problem of Fourier analysis of interferograms formed in terahertz (THz) synchrotron parallel beams, one of which is produced by surface plasmons (SPs) running along the surface of a conducting sample placed in one of the Mach-Zehnder interferometer arms, is considered in the paper. It is demonstrated that the anal…

In article technological process of covering when manufacturing obvodoobrazuyushchy details of aircraft is considered. Influence of cross-section stretching on plastic properties of metal is analyzed. The size of critical compressing tension and maximum permissible size of deformation of longitudinal stretching is def…
Many countries are planning to build or already are building new nuclear power plants to match their growing energy needs. Since all nuclear power plants handle nuclear materials that could potentially be converted and used for nuclear weapons, they each present a nuclear proliferation risk. Spent nuclear fuel present…
We have studied unique functions of DNA-modified nanoparticles, which disperse in an aqueous medium due to electrostatic repulsion between anionic phosphate groups in the DNA backbone. Interestingly, when complementary single-stranded DNA, whose base number is identical to that of the DNA on the surface, is added to t…
The authors argue that, in many cases, thicknesses of envelopes of buildings and structures are based on the thermotechnical calculation rather than their strength-related characteristics. Results of the thermotechnical calculation pre-define the degree of excess demonstrated by envelopes of buildings and structures.…
Shimkovich D.G. DYNAMIC LOADINGS AT CARGO OSCILLATIONS ON THE ROPE. In article the analysis behavior of oscillations of cargo on a rope is made at work of load-lifting cranes on the basis of two-mass model taking into account influence of initial conditions on possible values of dynamic loadings. The review of availab…
The effects of the support on active site formation and hydrodesulfurization (HDS) activity of Rh2P catalyst were examined, using metal oxides (MOx), such as SiO2, TiO2, Al2O3, MgO and ZrO2, as the support. Rh2P was formed on MOx support after reduction of supported rhodium and phosphorus (Rh–P) catalysts. However, di…
Based on the model of a nanocrystal as a rectangular parallelepiped with variable surface shape, the expressions for the melting point Tm and the temperature of the crystallization start TN
A system which realizes improved power generating efficiency and fuel conversion/reduced landfill disposal of sewage sludge by cooperative utilization of energy between a waste incineration plant and a sewage plant was proposed. Verification of these effects using the case of a midsized city as a model confirmed that…
INTRODUCTION: Cell microenvironments play a very important role in basic cell research, drug discovery and tissue engineering among others. The ability to define, create and control such microenvironments is rapidly increasing due to the application of microfluidic technologies in cell research. Electrospinning of pol…
По керамической технологии получены образцы композиционной керамики (1-x)ZrO 2-xSrTiO 3 с x = 0; 0,2; 0,4; 0,6; 0,8 и 1,0. С помощью методов РФА и РЭМ установлено, что все составы с 0 < х < 1,0 являются двухфазными и состоят из фазы кубического SrTiO 3 и фазы преимущественно тетрагонального ZrO 2. Исследованы диэлектр…
In order to prepare opal-based metal-dielectric systems one can use photonic crystal slabs coated with thin metal films. Usually the outer surface of thin metal layer covering opal sample is not flat: it is corrugated (e.g., periodically profiled like the opal-metal interface), making it possible to excite the surface…
In this study the temperature change of piano wires according to the load stress was measured using infrared stress measurement method. Piano wires used six sizes (0.1mm, 0.2mm, 0.4mm, 0.8mm, 1.0mm and 1.5mm). I used a fatigue testing machine for the three experiments. First of all, conduct an experiment to break the…
