Crystal Defects and Their Characterization in Modern Materials Science
Abstract: The physical and chemical properties of crystalline solids are fundamentally dictated by deviations from structural perfection, known as crystal defects. From the point-scale vacancies that drive diffusion to the planar boundaries that determine mechanical strength, defects serve as the primary "tuning knobs" in material design. This review provides a comprehensive examination of point, line, and planar defects, exploring their formation energetics and their role in plastic deformation via crystallographic slip. …

Nuclear Laser Techniques and the Use of Ion Exchange Resins for Radioactive Waste Removal
Abstract: The energy found in an atom's nucleus, or core, is referred to as nuclear energy. Electricity can be produced using nuclear energy, but it first needs to be released from the atom. A laser that has been nuclear pumped has been charged with energy from fission byproducts. In a nuclear reactor core, the lasing medium is housed in a tube lined with uranium-235 and exposed to strong neutron flux. The …

Identification of Elements Exist in Area Around Khartoum Petroleum Refinery Using Spectroscopic Method
Abstract: Laser-induced breakdown spectroscopy (LIBS) is a method of atomic emission spectroscopy (AES) that uses a laser-generated plasma as the hot vaporization, atomization, and excitation source. Plasma is often called the fourth state of matter. The various states of matter occur as a substance is heated to temperatures corresponding to thermal energies above the binding energies for particular state of matter. Structured systems placed in a sufficiently hot environment. LIBS technique …

General Notion of Temperament
Abstract: and retort by their energy, then previous potentials become reduced. The concept of temperament is the column of Unani Medicine. This concept was firstly introduced by Hippocrates when he specified that “It is more important to know what category of person a disease has then to know that sort of disease a person has”. Galen reflected that one pair of qualities out of four possibilities was main leading to the …

Pharmacophore mapping, 3D QSAR, docking, and ADME prediction studies of novel Benzothiazinone derivatives
Abstract: Background Tuberculosis is a major public health concern worldwide which is caused by Mycobacterium tuberculosis. DprE1 (Decaprenyl Phosphoryl Ribose 2’- Epimerase) is the most challenging target for development of novel anti- tubercular agents because it is a small protein and located into cytoplasmic membrane. So, novel anti-TB drugs did not bound effectively with it. DprE1 catalyzes the oxidation of the 2’ hydroxyl group of DPR (Decaprenyl Phosphoryl D- Ribose) …
