Platinum-based drugs, such as cisplatin, carboplatin, and oxaliplatin, have revolutionized chemotherapy and are widely used worldwide in the treatment of various types of cancer. These organometallic compounds have demonstrated high antitumor efficacy, which has driven their development and optimization over the decades. This review provides a historical overview of the discovery of platinum, the evolution of its organometallic compounds with pharmacological applications, and a current perspective on the use of nanomaterials as controlled drug delivery systems aimed at improving efficacy while reducing the adverse effects of these agents.

Saving energy technologies are clues in the extension and function of electric devices. To keep up with steady innovations in saving energy technologies, it is essential to progress corresponding practical strategies. In this research article, silicon carbide (SiC) has been designed and characterized as an anode electrode for lithium (Li), sodium (Na), beryllium (Be) and magnesium (Mg)-ion batteries due to forming SiLi2C, SiNa2C, SiBe2C and SiMg2C nanoclusters. A vast study on energy-saving by SiLi2C, SiNa2C, SiBe2C and SiMg2C complexes was probed using computational approaches due to density state analysis of charge density differences (CDD), total density of state (TDOS), localized orbital locator analysis (LOL) for hybrid clusters of SiLi2C, SiNa2C, SiBe2C and SiMg2C. Functionalizing of lithium, sodium, beryllium, and magnesium elements can raise the negative charge distribution of carbon elements as electron acceptors in SiLi2C, SiNa2C, SiBe2C and SiMg2C nanoclusters. Higher Si/C content can increase battery capacity through SiLi2C, SiNa2C, SiBe2C and SiMg2C nanoclusters for energy storage process and improve the rate performances by enhancing electrical conductivity. Besides, SiC anode material may advance cycling consistency by excluding electrode decline and augments the capacity owing to higher surface capacitive impacts. This research article is a promising model for a design-oriented exploration of next-generation anodes.

The mass production of tires, as well as the difficulty in reducing their waste, define a serious environmental problem. There are several methods for recycling discarded tires, one of the most common being mechanical shredding, in which the vulcanized rubber is separated from the steel and fibres, resulting in ground tire rubber (GTR). This rubber can be used in various applications such as insulating footwear soles, insulating floors, or as insulation for special electric motors. The objective of this research is to evaluate the use of this GTR when mixed with various types of polymeric matrix by measuring the mechanical, thermal, and dielectric properties of the resulting composites (polymer + GTR). The analysis was performed using four polymeric matrices (ABS, EVA, PA, and PP) mixed with different concentrations of GTR.
