Generally, graphite is used as an anode material due to its flat voltage plateau and economic viability. However, in addition to graphite's limited capacity, certain difficulties limit its future perspectives for usage in sophisticated batteries. Silicon has rather shown remarkable potential as a replacement for graphite mainly because of its high theoretical gravimetric capacity. Moreover, the capability of inserting/de-inserting lithium ions is way more in Si than graphite in current LIBs. However, it is seen that after a few cycles of charge and discharge, they get vulnerable to pulverizing mainly due to expansion of volume which happens during the alloying/dealloying. These issues can be addressed by incorporating novel mechanisms. Improvements in the anodes can be brought by binders, additives, composite electrodes, nanomaterials, and electrolyte solvents, to name a few. The solid electrolyte interphase (SEI) is another factor that needs to be taken into account. This review aims to enhance the effectiveness of the anode using the methodologies mentioned and extend this very strategy to design futuristic anode materials for LIBs in the future.

To keep up with these new advances, highly efficient catalytic routes need to be taken to be sustainable and ensure a drawn-out existence of resources for future generations. Catalysis turns out to be a significantly important field of application when it comes to the era of nanoscience, where all devices and technologies are becoming smaller and smaller in size with improved properties. When deeming the usability of a catalyst, it is of paramount importance to have a good understanding of their properties and their synergistic effect on the other reagents in the reaction. Over the last decade, the field of nanocatalysis has grown rapidly, both in homogeneous and heterogeneous catalysis. Given that nanoparticles have a high surface-to-volume ratio when compared to bulk materials, they are appealing as catalysts. Catalysts accelerate and boost thousands...
