The journal welcomes all kind of research/review/abstract papers regarding Engineering subjects including Earth and Planetary Sciences, Environmental Science, Chemical Engineering, Agricultural and Biological Sciences, Renewable Energy, Biochemistry.
Both lead (Pb²⁺) and hexavalent chromium (Cr(VI)) are highly toxic pollutants which need to have strategies for their removal. In this work, graphene oxide (GO) and thiourea-functionalized graphene oxide (TU-GO) were prepared and characterized by means of scanning electron microscopy (SEM), FTIR, Raman, UV-Vis, and BET analyses. Compared to GO, TU-GO showed higher surface area and enriched N/S functional groups. For adsorption experiments, an equilibrium was rapidly reached for Pb²⁺ and was slower for Cr(VI) uptake. Isotherm analysis revealed Pb²⁺ adsorption was Langmuir type monolaye
Read MoreThis study aimed to optimize the extraction of total polyphenols and antioxidant compounds from the bark of Ficus thonningii, a medicinal tree widely used in West African ethnopharmacology. Two extraction methods—maceration (MAC) and ultrasound-assisted extraction (UAE)—were compared at three solid-to-liquid ratios (S/L: 1/120, 1/80, and 1/60 g/mL) using an acetone/water solvent system (60:40, v/v). Both processes were carried out at 40 °C for 35 minutes, with kinetic sampling every 5 minutes. Total phenolic content was determined using the Folin–Ciocalteu method, while antioxidant acti
Read MoreThis study explores the bio-insecticidal potential of Zingiber officinale (ginger) leaf and rhizome extracts against stem borer larvae (Spodoptera spp.), a destructive pest that significantly impacts maize production. The widespread use of synthetic pesticides to control these pests has raised serious concerns about environmental safety, human health, and pest resistance. Consequently, there is an increasing demand for effective, plant-based alternatives that are both eco-friendly and sustainable. In this study, ginger extracts were prepared using Soxhlet and boiling extraction methods at vari
Read MoreWarning letters are the official notification sent by the USFDA to the manufacturing unit head or the organizational point of contact to point out the disparities and infringement and request a response. In recent years, the pharmaceutical industry has faced increased scrutiny regarding data integrity, prompting regulatory bodies to issue numerous warning letters to companies that violate established standards. The Food and Drug Administration (FDA) is a federal agency that takes charge of inspection, focusing on quality and safety as its top priorities. The FDA controls the food items and pha
Read MoreIndia the last decade pesticides detection and identification in food residue has been increased due to the health awareness of government and people. In Chhattisgarh state Bilaspur division the fresh vegetables like Cabbage, Tomato, Brinjal, Cucumber, Capsicum, etc. produced in agricultur area. The various pesticides like organophosphorus and organochlorine more and more uses in vegetables product. The study was focused for the detection and determination of chlorpyriphos residue in vegetables after harvest with UV-VIS spectrophotometer. The detection process was based on the alkaline hydroly
