Recently, there has been considerable interest in a new family of transition metal carbides, carbonitrides, and nitrides referred to as MXenes (Ti3C2Tx) due to the variety of their elemental compositions and surface terminations that exhibit many fascinating physical and chemical properties. As a result of their easy formability, MXenes may be combined with other materials, such as polymers, oxides, and carbon nanotubes, which can be used to tune their properties for various applications. As is widely known, MXenes and MXene-based composites have gained considerable prominence as electrode materials in the energy storage field. In addition to their high conductivity, reducibility, and biocompatibility, they have also demonstrated outstanding potential for applications related to the environment, including electro/photocatalytic water splitting, photocatalytic carbon dioxide reduction, water purification, and sensors. This review discusses MXene-based composite used in anode materials, while the electrochemical performance of MXene-based anodes for Li-based batteries (LiBs) is discussed in addition to key findings, operating processes, and factors influencing electrochemical performance.

Introduction: Recent medical improvements have not much of an influence on cancer patients' life expectancy throughout the world. Nano medicine is a cutting-edge topic in cancer therapy, with various well-tested techniques for delivering drugs. Objectives: Liposomes and other nanostructures are often used in therapeutic contexts and scientists in numerous countries are currently investigating polymer micelles. These structures will become more lucrative if they include chemicals that help with site-specific delivery and tailored release. The objective of the current review is to provide comprehensive information on nano-drugs. Methods: Liposomes, polymer micelles, and dendrites, among other well-known nanoparticle technologies, can be controlled and regulated to generate a more long-lasting and effective non-therapeutic modality. Occasionally, the term "multistage drug delivery" is used. This method, which employs a well-designed Nano-carrier, overcomes several biological barriers to medicine delivery. Results: Several multistage drug delivery system papers were reviewed for this study and their advantages were discussed with some pharmaceutical drug examples as well. Conclusions: We emphasize developments in nanoparticle design that overcome heterogeneous delivery barriers and contend that intelligent nanoparticle design can boost effectiveness in general delivery applications especially cancer treatment while enabling customized designs for precision applications, ultimately improving patient outcomes.
