Background: Photocatalytic hydrogen evolution from water splitting using photocatalyst semiconductors is one of the most promising solutions to satisfy the increasing demands of a rapidly developing society. CdS has emerged as a representative semiconductor photocatalyst due to its suitable band gap and band position. However, the poor stability and rapid charge recombination of CdS restrict its application for hydro Read More

Background: Many antibiotics were widely used as medication based on their distinctive features. Among them, sulphonamides were commonly and mainly used for bacterial treatment, however, the recalcitrant nature makes them difficult to dispose of. Hence, their interaction with the environment and analytic technique requires considerable attention globally. Objective: Therefore, this review aimed to provide a detaile Read More

Background: Nowadays, effective wastewater treatment has become a hot research topic in the field of environment. A series of novel activated carbon/ titanium dioxide (AC/TiO2) composites at various weight ratio were synthesised using the sol-gel method and were characterised using XRD, SEM-EDX, FT-IR, TGA and surface area analysis. Methods: TiO2 particles were successfully incorporated on the AC surface and wer Read More

Background: A simple, low cost and highly sensitive catalytic hydrogen wave (CHW) method has developed for the investigation of Manganese(II) in ammonium 4-phenylpiperazine-1- dithiocarbamate and ammonium 4-benzylpiperidine-1-dithiocarbamate in various environmental and biological samples using D.C. polarography. This procedure was based on the reaction of Mn(II) in APP-DTC/ABP-DTC in the presences of NH4Cl-NH Read More

Background: Environmental pollution has become a worldwide problem. In this regard, decontamination of wastewater and removal of organic pollutants from environment by photocatalysis has emerged as one of the most promising techniques from the last few decades. Objective: In order to degrade the harmful pollutants from wastewater, highly efficient non-toxic Fe2(WO4)3 photocatalyst was synthesized via co pre Read More

Background: Empty fruit bunch (EFB) is a type of biomass waste product formed during the production process of palm oil. In the present work, EFB was used to prepare a cellulose-graft-copolymer which can be converted into poly(amidoxime)-poly(hydroxamic acid) ligands suitable for the removal of heavy metals from electroplating wastewater. Methods and Results: Poly(amidoxime)-poly(hydroxamic acid) ligands were syn Read More

Background: Kraton/polyaniline ionomer is synthesized and further characterized by electrochemical studies to check the redox properties of the material. Ion exchange capacity, proton conductivity, and selectivity of the synthesized membrane were determined. And found that the membrane was selective for Cu (II) ions. Methods: The dry Kraton membranes were weighed and kept in 25 mL of 10 % prepared anilin Read More

Background: Nano perovskite-type structures as denoted by ABO3 (A= RE) have been popular targets of fundamental investigations since they exhibit a wide variety of physical properties depending upon the chemical composition, defects and small changes in atomic arrangements. Methods: GdAlO3: Co2+ (1, 3 &9 mol %) was synthesized using the solution combustion method by using stoichiometric quantities of gad Read More

Background: The organic effluents from industry remain one of the reasons for water contamination. By the natural degradation process, it is difficult to remove this; hence finding an effective solution for this is inevitable. TiO2-based materials have received enormous attention in the area of semiconductor photocatalysis, particularly for the degradation of organic dyes. This work emphasizes on the degradation of two indus Read More

Background: Nanomaterials-based cancer therapy plays a significant role in increasing the therapeutic efficiency of anticancer drugs, reducing side effects and targeted delivery of the drug payloads. The present study was aimed to enhance the anticancer effect of a novel dipeptide isolated from marine sponge-associated Bacillus pumilus AMK1 by formulating with Zinc oxide (ZnO) nanoparticles for the effective treatment ag Read More

Background: Infrared (IR) spectroscopy is a well-established technique for the structural elucidation of simple as well complex molecules. It has wide applications in the qualitative as well as quantitative determination of proteins in different samples. It provides a clear picture of the primary, secondary, or tertiary structure of a protein. Infrared radiations are used to assess different vibrational modes arise from variations in t Read More

Background: Dyes have been a blessing to mankind owing to their numerous applications in several industries ranging from textile, food, pharmaceuticals, and paper to leather, and many more. At the same time, these dyes pose a potential threat to mankind, when they are present beyond their permissible limits. This review covers the extraction and determination methods of dyes in different matrices. Introduction: Read More
