Ni-nanoTiN composite coatings were electrode posited on 45 steel substrate by using the ultrasonic-electrode position for nickel sulfamate bath. The effects of direct current, positive pulse current, reverse (positive and negative) pulse on surface morphology, binding force, micro hardness, friction and wear performan…
Overview of known genomic islands in Pseudomonas aeruginosa
Polymer-based nanocomposites (PNCs) display fascinating functionalities to be useful in electrical switching applications like circuit breakers, switch gears, etc. These PNCs are fabricated by incorporating nanoparticles (NPs) into a polymer by in-situ polymerization. When the PNCs interrupt the high energetic fault c…
CFD-laskenta eli numeerinen virtausdynamiikka on koko ajan entistä käytetympi menetelmä ratkoa nesteiden ja kaasujen virtaukseen liittyviä ongelmia, sillä se tarjoaa monia etuja perinteisiin fyysisiin koelaitteistoihin verrattuna. Usein on kannattavampaa suorittaa simulointi tietokoneella, jolloin vältytään suurien ja…
Проведено исследование спектров оптического поглощения квантовых точек ядро/оболочка InP/ZnS в широком диапазоне температур T=6.5-296 K. Методом производной спектрофотометрии второго порядка определены энергии оптических переходов при комнатной температуре: E1=2.60±0.02 eV соответствует первому экситонному пику поглощ…
One of the perspective directions of development of composite materials on the basis of their representation as multi-purpose systems with the corresponding system attributes is considered. The structure of quality functional is developed for objective assessment of quality of kinetic processes of formation of physic-…
In this paper, we study the hydrogen separation performance of bilayer graphene by molecular dynamics simulations. When the interlayer spacing between two grapheme sheets is larger than 5 , the impurities gas molecules can pass through the membrane. When the interlayer spacing is 5 , the permeance of hydrogen can reac…
The temperature-microstructure-stress/strain coupling model of YRT inner ring in the process of oil quenching and deep cryogenic treatment (DCT) were established to study the change rule of cooling process, microstructure evolution and residual stress distribution in the process of oil quenching and DCT. The results p…
You learned about the available upgrade methods in Chapter 2 in detail. Each method has unique features, prerequisites, steps, and constraints. You might be confused about how to choose the appropriate upgrade method for your environment. When choosing the right method, you need to know about the key features, limitat…
Bit-patterned media recording (BPMR) is a promising technology for ultra-high density media, however, there are some challenges that need to be addressed including two-dimensional (2D) interference, and track mis-registration (TMR). The system can experience TMR due to misalignment of the head and the track center. Co…
This article summarizes recent research and developments of membrane technology in the field of carbon capture and storage (CCS). Some examples of past and current European framework projects and Norwegian research council projects are classified into membrane types and application targets.
From macro perspective, main factors affecting adsorption of CH 4 by coals include coal particle size, pore structure, coal rank, moisture, temperature and pressure, etc.. The adsorption capacity of CH 4 by coals is affected by multiple factors. The adsorption experiment of single component gas showed that the absorpt…

Recycle program of spent nuclear fuel (SNF) will have some challanges in term of fuel cycle capability and its facilities as well as nuclear non-proliferation concern of special nuclear materials. A different analysis approach as a comparative study have been analyzed based on breeding ratio and heavy metal inventory…
Translocation of single molecules through biological nanopores provides valuable information about the physical and chemical structure of analytes. Such nanopores have been envisioned as tools for sequencing, biosensing, or characterization of biological interactions. However, many biological nanopores have limitation…
Nuclear reactor technology is growing rapidly, especially in developing Nuclear Power Plant (NPP). The utilization of nuclear energy in power generation systems has been progressing phase of the first generation to the fourth generation. This final project paper discusses the analysis neutronic one-cooled fast reactor…

The effect of multiple solution and aging treatment on microstructures and room-mechanical properties of Ti-53 alloy is studied by OM, SEM and universal material testing machine. The results show that the quantity of secondary α lamella, hardness, strength, and plasticity of Ti-53 alloy decrease after the peak value w…
Materials that demonstrate long range magnetic order are synonomous with information storage and the electronics industry, with the phenomenon commonly associated with metals, metal alloys or metal oxides and sulfides. A lesser know family of magnetically ordered complexes are the monometallic compounds of highly anis…
Электрический пробой воздуха около поверхности сжатой пластины из гранита вызывает появление в нем ударной волны. Добежав до обратной стороны пластинки, ударная волна обусловливает последовательное (с интервалом ~ 50 ns) выделение струй плазмы, состоящей из положительно заряженных ионов. Распределение струй по интенси…
