“…) is a group of software code which calculate the stopping and range of ions into matter using a quantum mechanical treatment of ion-atom collisions (assuming a moving atom as an "ion", and all target atoms as "atoms") [13,14]. The Transport of Ions in Matter, in short, (TRIM) is the most comprehensive program included.…”

In recent years, nuclear power plants have been built worldwide. This amount large of power is better than other energy sources for the environment, it does not have a greenhouse gas. A pressurized water reactor (PWR) is a type of light water reactor to generate electricity and it needed enriched Uranium and large cost. The purpose of this work was to investigate three different types of steel for PWR reactor vessels such as SA30400, SA302B and SA355B-1 steel. The result shows that SA355B-1 performs better than the other. On the other hand, phonons, ionization and collision events show very little damage to all materials.

“…Descaling, cleaning, pickling and acidizing oil wells are all businesses that use hydrochloric acid [1][2][3]. In acidic solutions, the corrosion inhibitors used are mostly heterocyclic molecules such as sulfur, phosphorous, oxygen, nitrogen, and aromatic or aliphatic organic chemicals, which are adsorbed on the surfaces of metals [4][5][6][7][8][9][10][11][12][13]. Due to the vacant d-orbital of iron atoms, the creation of a metal cation among inhibitor molecules as electron donors and metal surface atoms as electron acceptors has been hypothesized in corrosion research.…”

A theoretical study of 1, 3, 4-thiadiazole with nine various derivatives in gaseous and aqueous phases was investigated by employing the density functional theory (DFT) at 6-311++(d, p) basis set and Becke’s three parameters hybrid exchange-correlation functional (B3LYP). The molecules are calculated using quantum computational chemistry calculations such as Gaussian09 software. This paper is to determine the chemical reactivity for various heterocyclic organic compounds and to understand the process of corrosion inhibition. The quantum chemical properties such as the highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO), energy gap (∆E), dipole moment (μ), global hardness (η), global softness (S), electronegativity (χ), electrophilicity (ω), nucleophilicity (ɛ), chemical potential (CP) and electrons transferred from inhibitors to metal surface (ΔN) were calculated. Dynamic simulation approximations to demonstrate the corrosion inhibition performances of studied inhibitors against the corrosion of 1, 3, 4-thiadiazole in the gaseous and aqueous phases can be given as 1<9<8<3<4<5<6<7<2 and1<3<9<8<3<4<5<6<7<2

The goal of this work is to measure the rate of energy loss (stopping power) of alpha particles emitted from 241Am source as it passes through hydrogen gas which have been investigated using surface barrier detector in vacuum chamber. It was found that the loss energy of alpha particles in hydrogen gas decreases linearly with the increase in the pressure between 0 and 1 bar. The measured value of the range and stopping power were compared with SRIM code and ICRU. The predicted values based on the experimental, SRIM code and ICRU show good agreement with for stopping power and rang of alpha particle.
