Background: The advanced wastewater and water treatment by Reverse Osmosis (RO) system have almost become a common option in industries. However, achieving consistent RO feed quality the rigor of pre-treatment pose big challenge for specialists. Due to critical limiting parameters (Silica, Turbidity, BOD, Total hardness) inadequate consideration recycling plant design, Plant likely fails due sc...

In this work, the H3TRB performance of power modules with SiC MOSFET chips is investigated and compared to their silicon counterparts similar electrical ratings. For purpose, MOSFETs IGBT are packaged in same housing packaging technology an test performed on both types devices. The results show that while exhibit excellent performance, had a significantly longer time failure but also wider dist...

background: high concentration of salt makes biological treatment impossible due to bacterial plasmolysis. the present research studies the process of electrochemical oxidation efficiency and optimal levels as important factors affecting ph, salt concentration, reaction time and applied voltage. methods: the sample included graphite electrodes with specifications of 2.5 cm diameter and 15 cm he...

The purpose of this study was to examine the effect of an electro-ionizing toothbrush with stannous fluoride in the treatment of dentin hypersensitivity following periodontal surgery. Thirty-twQ volunteers with dentin hypersensitivity were dividcd in two equal groups each using different methods : (Group I ) stannous fluoride dentifrice and hyG Brnde ionizing brush without a battery and (Group ...

Given that many fundamental questions in neuroscience are still open, it seems pertinent to explore whether the brain might use other physical modalities than the ones that have been discovered so far. In particular it is well established that neurons can emit photons, which prompts the question whether these biophotons could serve as signals between neurons, in addition to the well-known elect...

Despite great progress in neuroscience, there are still fundamental unanswered questions about the brain, including the origin of subjective experience and consciousness. Some answers might rely on new physical mechanisms. Given that biophotons have been discovered in the brain, it is interesting to explore if neurons use photonic communication in addition to the well-studied electro-chemical s...

We report a comprehensive first-principles DFT study on (electro)chemical stability, intrinsic defects, and ionic conductivity improvement by halide doping of Na 3 SbS 4 electrolyte for all-solid-state batteries.
