Since their discovery, MXenes have conferred various intriguing features because of their distinctive structures. Focus has been placed on using MXenes in electrochemical energy storage including a supercapacitor showing significant and promising development. However, like other 2D materials, MXene layers unavoidably experience stacking agglomeration because of its great van der Waals forces, which causes a significant loss of electrochemically active sites. With the help of MoS₂, a better MXene-based electrodecan is planned to fabricate supercapacitors with the remarkable electrochemical performance. The synthesis of MXene/MoS₂ and the ground effects of supercapacitors are currently being analysed by many researchers internationally. The performance of commercial supercapacitors might be improved via electrode architecture. This analysis will support the design of MXene and MoS₂ hybrid electrodes for highly effective supercapacitors. Improved electrode capacitance, voltage window and energy density are discussed in this literature study. With a focus on the most recent electrochemical performance of both MXene and MoS₂-based electrodes and devices, this review summarises recent developments in materials synthesis and its characterisation. It also helps to identify the difficulties and fresh possibilities MXenes MoS₂ and its hybrid heterostructure in this developing field of energy storage. Future choices for constructing supercapacitors will benefit from this review. This review examines the newest developments in MXene/MoS₂ supercapacitors, primarily focusing on compiling literature from 2017 through 2022. This review also presents an overview of the design (structures), recent developments, and challenges of the emerging electrode materials, with thoughts on how well such materials function electrochemically in supercapacitors.

Since microcontrollers are used in so many modern electronics, power management has become an important part of making sure they work well and last a long time. This systematic study carefully looks at all the different sleep strategies that can be used on microcontrollers to manage power. By putting together, a lot of different pieces of literature, the study aims to give a full picture of the different approaches, problems, and progress made in using sleep strategies to make microcontroller-based systems use less power. The review uses a structured and organized method to find applicable studies, look at their methods, and pick out the most important results. It sorts sleep techniques into groups based on how they work, what they're used for, and how complicated they are. It is important to find similarities and differences between studies so that we can see what's new in microcontroller power management through sleep techniques. Some of the main topics that were looked at were how sleep strategies affect total power use, the trade-offs between saving power and reducing latency, and new trends in the field.
