Measurement of the direction of the elastic nuclear recoil track and ionization charge distribution along it, gives unique possibility for unambiguous detection of the dark matter WIMP particle. Within current radiation detection technologies only Time Projection Chambers filled with low pressure gas are capable of such measurement. Due to the character of the electronic and nuclear stopping po...

There is increasing demand to functionalize meso- and nanoporous materials by coating and make the porous substrate biocompatible or environmentally friendly. However, coating on a meso-porous substrate poses great challenges, especially if the pore aspect ratio is high. We adopted the pulsed laser deposition (PLD) method to coat Ni(3)Al-based meso-porous membranes, which were fabricated from a...

Abstract Single crystalline tungsten was irradiated by the medium-mass ion Si with 7.5 MeV and high mass-ion W 20.3 up to a calculated peak damage level of 0.04 dpa 0.5 dpa. The obtained dislocation structure zone investigated transmission electron microscopy systematically compared each other. Bright-field kinematical images were taken under four different two-beam diffraction conditions g = −...

This paper describes an approach, based on the analytical hierarchy process (AHP) that assists decision makers or manufacturing engineers determining the most appropriate manufacturing process to be employd in manufacturing of composite automotive bumper beam at the early stage of product development process. There are 5 types of processes under consideration namely injection moulding (IM), res...

During the exploitation of nuclear reactors, various U-Al based ternary intermetallides are formed in the fuel-cladding interaction layer. Structure and physical properties of these intermetallides determine the radiation resistance of cladding and, ultimately, the reliability and lifetime of the nuclear reactor. In current research, U(Al, Si)₃ composition was studied as a potential constituent...

It has been found that ion implantation can induce a swelling (step-height) phenomenon on crystal surface. In this paper, we studied about the control of swelling height of Si crystal by irradiating Ar beam under various parameters (fluence, charge and energy). These irradiation parameters were regulated by an irradiation facility that enables to achieve the multiple ionization. For both charge...

Most investigations of the gamma-shielding abilities materials are often based on Beer-Lambert law including recent studies clay-polyethylene composites. The findings usually silent secondary radiation effects that commonly occur due to photon buildup, known as Energy Absorption Buildup Factor (EABF) and Exposure (EBF). In this work, computation EABF EBF in region energy 0.015–15 MeV at differe...

Structural properties of materials irradiated with gamma-rays, such as mechanical and physical properties, may be modified or reduced depending on the displacement damages. Apart from increasing decreasing that property, damage desirable not. This study investigates effects sterilization by gamma radiation polycaprolactone (PCL) scaffolds. Using a code-based simulation method, MCNPX provides in...
