Both aluminum and its salts are commonly used by people. Aluminum salts are components of drugs. Such a widespread use of aluminum was enhanced by the belief that it is not toxic and is quickly excreted from the body with urine. It turned out, however, that this element has a negative impact on human health. Post-dialysis encephalopathy of patients with kidney malfunctioning was ascribed to the presence of aluminum in dialysis fluid. Aluminum cumulating in brain tissue is claimed to play a role in developing neurological disorders. This element affects bones as well as it causes disturbances in phosphorus and calcium levels, which is demonstrated chiefly by osteomalatia. Aluminium accumulation in the liver leads to cholestasis. This element causes numerous changes in peripheral blood and hemogenic system. It also causes normo- or microcytary anemia as it disturbs maturing of erythroblastic series cells and heme biosynthesis; it decreases osmotic resistance of red blood cells. Aluminum inhibits defensive mechanisms connected with white blood cells and macrophages. A number of processes, namely aluminum's hemolytic activity, blood cells' shorter lifetime or disturbed erythropoiesis process, are responsible for hematological changes.

Molecular junctions (MJs) are celebrated nanoelectronic devices for mimicking conventional electronic functions, including rectifiers, sensors, wires, switches, transistors, negative differential resistance, and memory, following an understanding of charge transport mechanisms. However, capacitive nanoscale molecular junctions are rarely seen. The present work describes electrochemically (E-Chem) grown covalently attached molecular thin films of 10, 14.

ConspectusLithium-ion batteries (LIBs) based on graphite anodes are a widely used state-of-the-art battery technology, but their energy density is approaching theoretical limits, prompting interest in lithium-metal batteries (LMBs) that can achieve higher energy density. In addition, the limited availability of lithium reserves raises supply concerns; therefore, research on postlithium metal batteries is underway. A major issue with these metal anodes, including lithium, is dendritic formation and insufficient reversibility, which leads to safety risks due to short circuits and the use of flammable electrolytes.

Developing efficient strategies for the deoxygenative functionalization of carbonyl compounds is crucial for enhancing the effective utilization of biomass and the upgrading of chemical feedstocks. In this study, we present an elegant cathodic reduction strategy that enables a tandem alkylation/dearomatization reaction between quinoline derivatives and aryl aldehydes/ketones in a one-pot process. Our approach can be executed via two distinct paths: the aluminum (Al)-facilitated spin-center shift (SCS) path and the Al-facilitated direct deoxygenation path.

The importance of fluorine and aluminum in all aspects of daily life has led to an enormous increase in human exposure to these elements in their various forms. It is therefore important to understand the routes of exposure and to investigate and understand the potential toxicity. Of particular concern are aluminum-fluoride complexes (AlF), which are able to mimic the natural isostructural phosphate group and influence the activity of numerous essential phosphoryl transferases.

The use of reduction leaching in the production of alumina from bauxite by the Bayer process in order to decrease the amount of waste (bauxite residue) by adding elemental iron or aluminum, as well as Fe salts and organic compounds in the stage of high-pressure leaching, requires the purchase of relatively expensive reagents in large quantities. The aim of this study was to investigate the possibility of the use of electrolytically reduced bauxite residue (BR) as a substitute for these reagents. Reduced BR was obtained from Al-goethite containing BR using a bulk cathode in alkaline suspension.
