Abstract: Since carbon dioxide (CO2) is one of the main contributors to global warming, its continuous increase in the atmosphere is a serious environmental concern. Therefore, CO2 gas capture is essential. To address this global issue, industries have proposed and implemented a variety of approaches and technologies, including CO2 capture, conversion, and reduction, using various materials, such as zeolitic adsorption, porous membranes, and amine solution absorption. Nevertheless, these technologies are costly and energy-intensive. A novel family of porous materials......

Abstract: Background: Pandanus odoratissimus is traditionally used across Southeast Asia, yet comparative profiling of key secondary metabolites between organs remains limited. This study addressed that gap by comparing phenolics, flavonoids, and saponins in leaves and stems collected from coastal regions of central Vietnam.
Materials and Methods: Six leaf and six stem samples were ethanolic-extracted (90%, sonication), and total phenolic content (TPC) was quantified......

Keywords: Pandanus odoratissimus; phenolics; flavonoids; saponin; alkaloids.

Abstract: This study investigates noise pollution variations in Janseva Shikshan Mandal's Shantarambhau Gholap Arts, Science, and Gotirambhau Pawar Commerce College, Shivle, Murbad, during three distinct phases: pre-lockdown (November 2019), lockdown (April 2020), and post-lockdown (February 2022). Noise levels were measured across 12 key locations, including residential, commercial, and silence zones, using a sound level meter at one-hour intervals. The collected data were analyzed and compared against the standards set by the Environmental Protection....

Abstract: The objective of this work is to optimize the production of activated carbon synthesized from Zizyphus Mauritiana (L.) Lam. shells and to determine the iodine and methylene blue indices. The shells of the selected biomass are impregnated with a solution of orthophosphoric acid (H₃PO₄) and sulfuric acid (H₂SO₄). The activation and pyrolysis parameters (concentration effect, impregnation rate, impregnation time, and pyrolysis temperature) were studied. The iodine and methylene blue indices were determined using the CEFFIC method. The results obtained show....

Abstract: Fluoride is a naturally occurring compound derived from fluorine. It occurs naturally in public water system as results of runoff from weathering of fluoride containing rocks and soils. It is toxic in high conc. Due to high toxicity of fluoride to mankind, there is urgent need to treat fluoride contaminated drinking water to make it safe for human use. In the present study pineapple peel powder is used as a biosorbent for fluoride removal from groundwater. The fluoride removal efficiency of pineapple peel powder was investigated by Batch wise adsorption experiment. The effect of various parameters on the %age removal of flouride was studied. e.g. contact time, adsorbent dose, pH..

Keywords: Pineapple peel, Biosorption, fluoride, contact time, Adsorption.

Abstract: Oxidation of Tartaric acid by pyridiniumdichromate in DMSO (dimethylsuphoxide) as a solvent in presense of PTSA (p- toluenesulphonic acid). The reaction is first order with respect to oxidant and [H+]. The reaction exhibit no primary kinetic isotop effect. The activation parameters have been evaluated. Michaelis – Menten type kinetics is observed. The rate of reaction decrease with an increase in the polarity of solvent indicating an ion-dipole interaction in the slow step..
