Abstract:
Molecular solar thermal (MOST) energy systems can be utilized for the absorption, storage, and release of energy from the ultraviolet (UV) band of the solar spectrum. In this study, we designed a molecular solar thermal energy storage and release device based on the photoisomerization reaction of azobenzene. The device was integrated with a parabolic trough solar system, broadening the absorption range of the solar spectrum. By utilizing a coated secondary reflector, the system achieved efficient reflection of ultraviolet (UV) light in the 290–490 nm range, while solid-state azobenzene enabled

Abstract:
A study was carried out during 2021-22 considering various vegetable growing farmers in Unnao District (U.P.) to find out the effect of using industrial effluents as the only source of irrigation to their crops. 250 surface soil samples collected from farmer’s field were analyzed for physical as well as chemical parameters. The physical properties of soils improved due to industrial effluent irrigation. Among the physical properties bulk density ranged from 1.15 to 1.55 Mg m-3 and particle density ranged between 2.61 to 2.86 Mg m-3. Chemical Parameters of soil such as pH , EC, OC, Available N,

Abstract:
Here we describe a simple, rapid and accurate method for simultaneous assay of aspirin and omeprazole. The first method was Absorbance ratio method (Method 1) and second method was multi component mode method of analysis (Method 2). Methanol: water (8:2) was used as solvent for both methods, using 293 nm as isobestic point for absorbance ratio method. The wavelength ranges 275.80 nm for aspirin and 302.20 nm for omeprazole for method 2, which represents the absorbance maxima of both drugs respectively. Beer’s law was applied in the concentration ranges of 2-14μg/mL and 2-18 μg/mL for aspirin a

Abstract:
Using straw and urea as raw materials, biochar (BC) and g-C3N4 were prepared by oxygen-free pyrolysis at 300°C and 550°C. BC/g-C3N4 was prepared by loading different amounts of g-C3N4 onto the surface of biochar and characterized by SEM and FT-IR. The adsorption effect on methylene blue (MB) was investigated from the aspects of dosage and pH. The studies of adsorption equilibrium isotherms and the kinetic and the thermodynamic parameters on the BC/g-C3N4 adsorbents are discussed. The results showed that BC/g-C3N4 0.16 g/L with a doping ratio of 1 : 3 was added to the MB solution with an initia

Oxidative stress is an imbalance between the production of Reactive Oxygen Species (ROS) and antioxidants in the body. One plant that contains antioxidants is binahong leaves (Anredera cordifolia (Ten.) Steenis). To determine the compound content contained in binahong leaves, a total antioxidant capacity test and toxicity test were carried out on binahong leaves. This research used an in-vitro experimental study consisting of an antioxidant capacity test with DPPH (1.1-diphenyl-1-picrylhydrazil) and a bioassay, namely a toxicity test with the Brine Shrimp Lethality Test (BSLT) from binahong le

Development of the internet and electronic media provide a convenient platform for travellers to instantly share their experiences. Known as electronic word-of-mouth (eWOM), it offers a powerful source of information and can also act as an effective marketing tool. Existing studies have focused on the conceptualisation and influences of eWOM communication, but limited attention has been given to the antecedents of it from the attitUdinal perspective within the tourism industry. This study aims to fulfil that gap. Data from international travellers having experience of eWOM communication was co

Abstract:
Compared with face-to-face communication, Facebook use may provide opportunities for greater interaction in a relatively uncensored environment. This research aimed to critically investigate how Saudi university students are using these opportunities. It employs a theoretical framework drawn from uses and gratifications theory, social penetration theory, and social role theory. A mixed methods approach was used over three sequential phases. The research began with a quantitative questionnaire completed by 372 Saudi university students to investigate the gratifications they obtained from using
