Effects of a nitriding treatment on the tensile and high cycle fatigue properties were investigated by conducting ionnitriding and gas nitro-caburizing treatments on the spheroidized SCr430B medium-carbon steel and performing tensile and tension-tension high cycle fatigue tests. The nitrided samples showed much lower…
The newest phases to be identified - fullerenes, nanotubes, and graphemes. This chapter presents the main methods of production for these three groups and then at their identification and potential use in two promising sectors. To do this, it begins by discussing the conditions of synthesis, purification and productio…
Pengecoran merupakan salah satu bagian dari proses produksi, dimana bahan dalam kondisi cair dituang atau dicetak dengan tekanan dalam sebuah rongga cetakan dengan bentuk tertentu dan dibiarkan sampai berubah menjadi padat atau membeku. Pengecoran logam kental atau semi solid casting merupakan bagian dari pengecoran b…

We tested the efficiency of the MPI cluster in NIRDIMT by using a Quantum Monte Carlo algorithm (QMC). While the algorithm is highly efficient we show that a decrease of the computing efficiency occurs if the processor number is larger than eight.
New energy materials have been investigated, including hydrogen storage materials and \ndilute nitride semiconductors. The two potential hydrogen storage materials to have been \ninvestigated are di-sodium amide borohydride (Na2NH2BH4) and lithium sodium \nborohydride (LiNaBH4). Additionally, the homoepitaxial growth…
Abstract : The long-term objective of this proposal was to design nanotubes that would preferentially target cancer cells and surrounding endothelial cells, and then to use these materials as transducers of near-infrared radiation for laser-induced thermal therapy of kidney cancer. In the work supported by this grant,…
Modern nuclear reactor safety codes require the ability to solve detailed coupled neutronic- thermal fluids problems. For larger cores, this implies fully coupled higher dimensionality spatial dynamics with appropriate feedback models that can provide enough resolution to accurately compute core heat generation and re…
Confined liquid crystals (LCs) have attracted much interest because their richness in physical phenomena and potential applications. In this thesis the configuration of novel liquid crystal phases confined in cylindrical cavities from tens of nanometres to hundred of microns primarily were investigated by means of sma…
The dry etching characteristic of Al 1.3 Sb 3 Te film was investigated by using a CF 4 /Ar gas mixture. The experimental control parameters were gas flow rate into the chamber, CF 4 /Ar ratio, the O 2 addition, the chamber background pressure, and the incident RF power applied to the lower electrode. The total flow ra…
Direct drive train requires the use of full scale converter for controlling the generator speed and power. This converter contains either active rectifier or diode rectifier. The converter with diode rectifier is simple and not expensive. However, it injects low-frequency current harmonics to the generator thus causes…

The present study was made to demonstrate the annealing behavior of severely deformed interstitial free (IF) steel processed by differential speed rolling (DSR). The initial ferrite grain size of ? 35 ㎛ was significantly refined to ? 0.7 ㎛ after four DSR operations corresponding to the effective strain of ? 1.7 under…
To study pattern Auto-generation system based on silk fabric properties, it is proposed a concept about rapid generation of individualize pattern. By carrying out instrumental tests on the 3-silk fabric properties and sample wear trials, the regression mathematical models between fabric properties and parameter patter…
Many applications of modern physics require the investigator to understand the behavior of specific atoms in compounds. The behavior and structure of molecules such as sodiumaluminohexahydride (Na3AlH6) is relevant to the field of hydrogen storage [1]. In this study, we used nuclear magnetic resonance to examine the b…
Pipe continuous extrusion-process using spring type of wire material was designed for continuous production of pipe. Unlike the existing pipe extrusion process, it is possible to extrude pipe continuously without limit of length of pipe. This paper is studied in basic research about pipe continuous extrusion-process u…
The aim of this project is to develop fly ash based geopolymer concrete and study the effects of fibres and curing temperature on the compressive strength (and other values that define the behaviour of geopolymer concrete in compression). Testing involves compressive loading of 100 mm (diameter) by 200 mm (height) cyl…
In this study, the microstructures and mechanical properties of the recently developed Eco-2024-T3 alloy were examined. Eco2024 is made using Eco-Mg(Mg-Al₂Ca)in place of element Mg during the manufacture of alloy 2024-T3. This is an alloy that has economic advantage and excellent properties. Alloy Eco2024 showed small…
A simulation model of road train movement has been developed. The model includes a tractor of a KrAZ class and a trailer for timber transport. The effect of the control algorithm on the suspension stability of the train at the corners has been studied
