The disinfection of wastewater using nanoparticles (NPs) has become a focal area research in water treatment. In this study, zinc oxide (ZnO) NPs were synthesized the microwave heating crystallization technique and characterized transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy X-ray diffraction (XRD). Qualitative well diffusion quantitative minimum inhibitory concentration (MIC) tests conducted to determine antimicrobial activity ZnO against selected...
Abstract Photoelectrochemical cells (PEC) use solar energy to generate green hydrogen by water splitting and have an integrated device structure. Achieving high solar‐to‐hydrogen conversion (STH) efficiency along with a long operational lifetime in these is crucial for the production of low‐cost as viable source. Several functional components, such photo absorber, charge transport, catalyst layers are interfaced form compact monolithic device. In this review, therefore, engineering design...
The increasing antimicrobial resistance (AMR) caused by commonly used agents during wastewater treatment processes has prompted the use of nanomaterials as alternative agents. present study aimed to determine activity biopolymer nanocomposites synthesized using a combination phosphorylation and cross-linking polymerization techniques. nanocomposite, pCh-MWCNTs@Ag-TiO2, along with its intermediate product (pCh-MWCNTs), was characterized spectroscopy, thermogravimetric analysis, microscopy...
Domestic, agricultural, and industrial waste has been investigated as a substitute for activated carbon adsorbents. For instance, the transformation of tea to biochar can be utilized In this study, waste-based adsorbents (biochar, biochar/reduced graphene oxide (biochar/rGO), oxide/deep eutectic solvent-cetyltrimethylammonium bromide (biochar/rGO/DES-CTAB), solvent-glycerol (biochar/rGO/DES-glycerol)) were synthesized by simple thermal treatment sucrose followed modification with reduced...
A multifunctional nanobiocomposite polymer was developed in this study through a cross-linking polymerization of cyclodextrin with phosphorylated multi-walled carbon nanotubes followed by sol-gel to incorporate TiO2 and Ag nanoparticles. This work’s novelty prove that the is potential filter nanosponge capable removing organic, inorganic, microorganisms’ pollutants from wastewater samples. The synthesized characterized using range spectroscopy electron microscopy techniques....
Defects both in bulk and at the interfaces serve as charge trapping sites for nonradiative recombination ion migration pathways, resulting degradation of perovskite solar cell efficiency stability. In this work, a strategy simultaneous passivation interfacial defects is reported. For polystyrene (PS) used an additive precursor which reduces structural by forming larger defect‐free grains. While F‐PEAI cation to passivate defects, present HTL/ETL interfaces. Furthermore, conducting control...
The availability and quality of water resources is currently the primary concern in Southern Africa. challenge to improve or develop treatment materials methods solve this problem potable scarcity. Hence, article presents analyzed data, which are supplementary data information on study bio nanosponge phosphorylated-carbon nanotube/nanoparticles polyurethane composite (pMWCNT/β-CD/TiO2-Ag) as polymeric nanobiosorbent, for treatment. developed nanobiosorbent was synthesized using combined...
To date, in South Africa alone, there are an estimated 4.5 million people receiving antiretroviral (ARV) therapy. This places as the country with largest ARV therapy programme world. As a result, increasing number of reports on occurrence ARVs African waters. Achieving efficient and bio-friendly methods for removal these pollutants is considered concern environmental researchers. study aims at studying efficiency moving bed biofilm reactor (MBBR) system removing from wastewater.
