Pressure effect on diffusion of carbon at the 85.91◦ 100 symmetric tilt grain boundary of α-iron
(American Physical Society, 2021-04-19)The diffusion mechanism of carbon in iron plays a vital role in carburization processes, steel fabrication, and metal dusting corrosion. In this paper, using the kinetic activation-relaxation technique (k-ART), an off-lattice kinetic Monte Carlo algorithm ... -
Diffusion mechanism of bound Schottky defect in magnesium oxide
(American Physical Society, 2021-03-25)In simple ionic crystals, intrinsic point defects must satisfy electrical neutrality and exist as Schottky defects. In magnesium oxide (MgO), a Schottky defect is then a combination of anionic and cationic vacancies. Since vacancies are charged, the ... -
Molecular interactions of tannic acid with proteins associated with SARS-CoV-2 infectivity
(MDPI, 2022-02-27)The overall impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on our society is unprecedented. The identification of small natural ligands that could prevent the entry and/or replication of the coronavirus remains a pertinent ... -
Insights on the effect of water content in carburizing gas mixtures on the metal dusting corrosion of iron
(Elsevier, 2021-12-07)Constituents of syngas, such as water, carbon monoxide and sulfides, can cause the degradation of the steel pipes they move through, leading to carbon dusting and corrosion. In spite of considerable attention to this process, many questions remain ... -
Zirconia-titania-doped tantala optical coatings for low mechanical loss Bragg mirrors
(American Vacuum Society, 2021-06-10)The noise caused by internal mechanical dissipation in the high refractive index amorphous thin films in dielectric mirrors is an important limitation for gravitational wave detection. The objective of this study is to decrease this noise spectral ... -
Comparison of three radio-frequency discharge modes on the treatment of breast cancer cells in vitro
(Institute of Electrical and Electronics Engineers, 2019)Non-thermal plasmas (NTPs) are known for their ability to induce thermal-free cytotoxic effects on cancer cells. However, as the variety of NTP devices increases, comparison of their cytotoxic effect becomes increasingly essential. In this work, we ... -
Mitigating Alzheimer’s disease with natural polyphenols: a review
(Bentham Science, 2019-03-14)According to Alzheimer’s Disease International (ADI), nearly 50 million people worldwide were living with dementia in 2017, and this number is expected to triple by 2050. Despite years of research in this field, the root cause and mechanisms responsible ... -
A coupled 2 x 2D Babcock-Leighton solar dynamo model. II Reference dynamo solutions
(American Astronomical Society, 2017-01)In this paper we complete the presentation of a new hybrid 2 × 2D flux transport dynamo (FTD) model of the solar cycle based on the Babcock–Leighton mechanism of poloidal magnetic field regeneration via the surface decay of bipolar magnetic regions ... -
Focussed helium ion channeling through Si nanomembranes
(2018-03-15)Channeling of low energy (25 to 35 keV) focussed He ions transmitted through crystalline Si (001) nanomembranes (50nm) has been observed using a He ion microscope. Planar (110) and (100) channeling was detected with critical incident angles of 1.0 at ... -
Computer Simulation of Ion Beam Analysis: Possibilities and Limitations
(2011)Quantitative application of ion beam analysis methods, such as Rutherford backscat- tering, elastic recoil detection analysis, and nuclear reaction analysis, requires the use of computer simulation codes. The different types of available codes are pre- ...
