Abstract: Artificial sweeteners are being used extensively especially by diabetes and obesity and have entered most of the food industries, some of them contain natural compounds, but they are low in sweetness. Others are classified as high in sweetness, which are dangerous and harmful to health because they contain chemical additives, which are still under study, also in markets there are pure sweeteners or sweeteners mixed with these industrial chemical additives. A selection of one common and commercially available table-top artificial Sweetener in Sudanese Markets (süssina) was considered. The study was conducted by using Raman spectroscopy Model Horiba LabRAM HR 3D to examine the components of these industrial chemicals additives in the normal situation and after heating at boiling point of water. The study showed the presence of sorbitol (C6H14O6), a natural component of corn, Aspartame (C14H18N2O3) and saccharin (C7H4NNaO3S) which are artificial chemical additives.

Abstract: Crystallite size and lattice strains in cadmium (Cd) powders produced by milling have been analyzed by X-ray powder diffraction. The lattice strain (ε) and Debye-Waller factor (B) are determined from the half-widths and integrated intensities of the Bragg reflections. In Cd the Debye-Waller factor is found to increase with the lattice strain. Cadmium powder was ball milled in an argon inert atmosphere. The milled powders were characterized by X-ray diffraction. The high-energy ball milling of Cd after 25 hours resulted in particle size of 21 nm. Lattice strains in Cd powder produced by milling have been analyzed by X-ray powder diffraction. The lattice strain (ε) and Debye-Waller factor (B) are determined from the half-widths and integrated intensities of the Bragg reflections. Debye-Waller factor is found to increase with the lattice strain. From the correlation between the strain and effective Debye-Waller factors have been estimated for Cd. The variation of energy of vacancy formation as a function of lattice strain has been studied.

Abstract: This review paper deals with Spintronics and its role to improve electronic devices. There is a occurring continuously interest for faster and higher density with lower power forms of information processing and storage, which could not be met by electronics devices whose base is the electron flow charge. In this review an Attempts was done on the other fundamental property of an electron, which is called as spin, have given rise to a new, rapidly evolving field, known as spintronics, an acronym for spin transport electronics. In Spintronics is a new technology was developed in which the spin of electrons is altered in addition to the charge of it for device functionality. In this review I am motivated to study fundamental logics of spin, and basic Spintronics technology including its advantages and utilization in various applications like Quantum computing, Magnetic Random Access Memory (MRAM) and Quantum Cryptography. The primary focus is on the technological description in Spintronics, its devices, working principle of Spintronics, its advantages and disadvantages, and its challenges.

Abstract: This review paper was conducted to compare theoretical value with experimental one to provide the charging and discharging capacitor using different value of capacitance, voltage and resistance. Thus on the experiment part was conducted by me and the theoretical one is on the literature part, what if after doing this experiment, When charging capacitor voltage and charge are increase and current are decrease exponentially, where as in discharging capacitor current decrease and similarly voltage and charge are decrease exponentially. This results that experimental value is almost agree with the theoretical one.
