Summary: Research into the antibacterial properties of copper oxide nanoparticles (CuO NPs) is gaining traction. CuO NPs produced using a simple precipitation process were studied for structural and antibacterial characteristics. As a precursor, copper (II) acetate was employed, and sodium hydroxide was used as a reducing agent. The crystalline structure of CuO NPs was shown […]

The fluorescent matrix of Tris-(8-Hydroxyquinoline) Aluminium and the optical and electrical properties of semiconducting Zinc Oxide (ZnO) nanoparticle systems were investigated (Alq3). To better understand these features, we used an aqueous sol-gel approach to make ZnO nanoparticles with particle sizes ranging from 23 nm to 110 nm, annealed them at high temperatures, and made an […]

In the fields of science and engineering, the Double Exposure Holographic Interferometry (DEHI) technology has a wide range of applications. DEHI can be used to detect minute surface changes in an object over short time periods. This can be used to figure out or evaluate some material’s physical qualities. The DEHI technique is utilised in […]

Transition metal oxides are a special class of materials that have a wide range of optical, electrical, and mechanical properties. Nickel oxide (NiO) is a p-type oxide semiconductor by nature. When combined with transparency and low temperature (low-T) fabrication processes, P-NiO with controllable and repeatable physico-chemical properties can be fully exploited in a wide range […]

So far, extensive research on CFAs from Greece has been conducted on a variety of topics, including their content of radioactive isotopes, trace elements, and PAHs, their use in engineering works, agriculture, waste management, trace element behaviour and leachability, the production of synthetic zeolites, and their impact on soil properties and plant growth. As a […]

World over, in the history of mining, various mining method selection techniques such as qualitative and multi-criteria decisions approaches have been applied to choose an appropriate mining method. However, to date no single mining method selection technique has been universally adopted due to the variations and number of factors involved in the selection process which […]

This manuscript discusses the current situation of organomineral fertiliser production and use, as well as ways for obtaining them from various types of raw materials. Also given are the findings of a study of phosphorus production waste and coal mining waste. Experimental, physico-chemical, and analytical procedures were employed to meet the research objectives: screening, chemical, […]

The seasonal change of 210Po and 210Pb in the soil and sediment of the Hemavathi River Environment is discussed in this paper. The concentration of 210Po and 210Pb in the samples was evaluated using a conventional radiochemical analytical method during the pre-monsoon and monsoon seasons. In the monsoon and pre-monsoon seasons, the mean activity concentration […]

Under solvent-free and energy-efficient circumstances, a generic and practicable approach for un-catalyzed esterification of alcohols using acetyl chloride is disclosed. Nowadays, catalyst- and solvent-free processes are far more safe, nontoxic, ecologically friendly, and cost-effective. This approach is economical and environmentally friendly due to its high yields, extensive applicability to diverse alcohols, mild reaction conditions, short […]

Chemically treated jute fibre is added to starch-chitosan blended films that are crosslinked with calcium chloride in this study. Because starch-chitosan films are brittle and soluble, 1 percent, 2 percent, 3 percent, and 4 percent jute fibre was added to make the blended film more hard and stable and to increase its strength and make […]
