This paper reports a systematic study on the elastic property of bulk silicon nanomaterials using the atomic finite element method. The Tersoff-Brenner potential is used to describe the interaction between silicon atoms, and the atomic finite element method is constructed in a computational scheme similar to the conti…
A simple geometrical method of the analysis of X-ray diffraction patterns from crystals with arbitrary atomic lattice containing stacking faults and thin microtwin plates is presented. The theory takes account of the effect of changing interplanar spacing along the line of the intersection of a lattice plane with a st…
In the continuous casting of steel, the state of the mold flux plays a significant role in the quality of the steel as well as the casting operation. In this study, the state of the mold flux was estimated by measuring the friction force of mold oscillation and establishing a lubrication model. The friction force was…
Indira Gandhi Centre for Atomic Research, Kalpakkam has successfully designed a 500 MWe prototype fast breeder reactor (PFBR). It is a proven fact that the critical factor in ensuring safe and reliable operation of any nuclear power plant is a qualified and well-trained personnel and hence, the need for operator train…
Weld flaws often require an engineering critical assessment (ECA) to judge on the necessity for weld repair. ECA is a fracture mechanics based prediction of the integrity of welds under operating conditions. Adding to the complexity of an ECA is the occurrence of local constitutive property variations in the weldment…
In this paper, the preparation methods of aluminum-magnesium alloys are reviewed. The three methods of preparation of aluminum-magnesium alloys are introduced: the mixing method, mechanical alloying method, electrodeposition method. And the advantages and disadvantages and characteristics of three methods are expounde…
"In this paper a methodology for the alignment of waves in the photoplethysmography (PPG) register signal is shown. The procedure uses algorithms for dynamic programming and for optimization in order to generate a single segmentation of these waves in the PPG signal and the individual reconstruction of each wave. By a…
Nanomaterials are a new and growing type of material, and concerns have been raised regarding their potential risks to human health and to the environment. These concerns have spurred the development of risk assessment methods with the\npurpose of assessing risks related to nanomaterials. However, such developments ha…
Using Pd/Pt-decorated solar light active ZnWO 4 /mixed-phased TiO 2 nanofibers as a model subject, we investigate the prerequisites for the construction of mechanically stable metal oxide nanofibrous membranes.
test and micronucleus assay in different concentrations (from 1.25 μg/mL up to 100 μg/mL, depending on the test and the extract). Applied concentrations were based on a preliminary dose-finding test with the neutral red uptake assay. The results show that all extracts were not genotoxic in the presence or absence of a…
Stress distribution in multi-step ion-exchanged glass could not be measured accurately by conventional non-destructive stress measurement instrument and method. Therefore, by applying improved algorithm, stress distribution in 2-step ion-exchanged glass was evaluated. By comparing the results with 3 destructive measur…
Highly pure compressed hydrogen gas can be efficiently generated via a facile hydrothermal process of iron powders and water by the assistance of acid and Pd catalysts.
The combination of metallic and ceramic materials allows the combination of positive properties of both and can be applied in various industrial fields. At the moment, the deployment of these composites faces difficult and complex manufacturing. One attempt, which offers a short process route and a high degree of flex…
Desensitization caused by pre-shocking in heterogeneous explosives is discussed. The aim of this study was to find a simple numerical model that could reproduce the important features of previously reported shock desensitization experiments. After reviewing the previous experimental results and modelling efforts, an e…
Innovative spatial forms arise and develop at an intersection of science and art, engineering and architecture. Various geometric structures with different types of symmetry are studied by mathematicians, engineers and architects. Computer simulation reveals a new range of geometric shapes as well as various types of…
With glycidyl azide polymer-energetic thermoplastic elastomer (GAP-ETPE) as the binder, cyclotrimethylenetrinitramine (RDX)-based nanocomposites were prepared from their cosolution by spray drying. The particle size and morphology of explosive samples were characterized by scanning electron microscope, transmission el…
