Tubular solar still is a simple light-weight desalination unit with large condensing surface compared other types of stills. Regrettably, it suffers from the low water yield like In this work, two main research themes are studied. The first enhancing and thermal efficiency tubular by providing absorber plate an electrical heater powered photovoltaic panel. performance modified evaluated based on its as well energy exergy efficiencies. second developing fine-tuned artificial intelligent model...

Lack of suitable auto/allografts has been delaying surgical interventions for the treatment numerous disorders and also caused a serious threat to public health. Tissue engineering could be one best alternatives solve this issue. However, deficiency oxygen supply in wounded implanted engineered tissues, by circulatory problems insufficient angiogenesis, rate-limiting step translation tissue-engineered grafts. To address issue, we designed oxygen-releasing electrospun composite scaffolds,...

Abstract The objective of the current study is to assess structural , optical filter property, and photoluminescence a glass system primarily made barium phosphate doped with vanadium pentoxide (V2O5), in which units (P2O5) are replaced by tellurium oxide (TeO2). network consists PO4 Q2 Q3 modes, while TeO2 exists as trigonal pyramid TeO3 units. Density decreased from 3.263 3.046 g/cm3 addition up 15%, then increased 3.486 at 20% TeO2. Depending on TeO₂ concentration, produces region zero...

This study investigated nonstoichiometric nickel oxide thin films prepared via the DC-sputtering technique at different film thicknesses. The were characterized by a surface profiler for thickness measurement, X-ray diffraction (XRD) nature, atomic force microscopy (AFM) morphology and roughness, UV-visible-near infrared (UV-vis.-NIR) spectroscopy optical transmittance spectra of films, photoluminescence (PL) obtained. measured increased from 150 to 503 nm as deposition time increased. XRD...
