“…This is because the sun does not shine for ever and neither does the wind blow for ever. Electrochemical methods like batteries, fuel cell and supercapacitors are the recognised most potent, efficient and reliable energy storage technologies [1][2][3][4][5][6][7][8][9][10][11][12]. Among these, Supercapacitors also called as ultracapacitors or electrochemical capacitors are most promising and have significant application prospects due to their enhanced power density facilitated by its rapid rate of charging and discharging, performance stability even after large number of charging-discharging cycles, broad temperature range of functionality, low cost of maintenance and ease of use.…”

In the world of energy storage devices, Supercapacitors occupy a very unique and pivotal position. Their rapid rate of discharge gives them high power density. They have high reversibility and are robust to a large number of charging and discharging cycles. Sustained research has revealed a certain set of properties and behaviour, that every prospective candidate supercapacitor material must possess. Metal organic frameworks (MOFs) with unique textural properties, excellent specific surface area, tuneable porous structure and distinctively advantageous electrochemical behaviour are prominent candidates for the use in energy storage applications. However pristine MOF based materials are handicapped due to their low conductivity and poor mechanical stability. These inherent deficiencies can be overcome by hybridizing pristine MOFs with other materials like carbon materials (Activated Carbon, Graphene and Carbon Nano Tubes), conducting polymers, metals, and small molecules through variety of methods. This review puts the spotlight on the utilization, growth and various forms of hybrid materials based on MOFs for supercapacitor applications. It also highlights the various surface engineering techniques on the materials for high potential applications.

The world is facing a global financial loss and health effects due to food quality adulteration and contamination, which are seriously affecting human health. Synthetic colors, flavors, and preservatives are added to make food more attractive to consumers. Therefore, food safety has become one of the fundamental needs of mankind. Due to the importance of food safety, the world is in great need of developing desirable and accurate methods for determining the quality of food. In recent years, the electrochemical methods have become more popular, due to their simplicity, ease in handling, economics, and specificity in determining food safety. Common food contaminants, such as pesticides, additives, and animal drug residues, cause foods that are most vulnerable to contamination to undergo evaluation frequently. The present review article discusses the electrochemical detection of the above food contaminants using different carbon nanomaterials, such as carbon nanotubes (CNTs), graphene, ordered mesoporous carbon (OMC), carbon dots, boron doped diamond (BDD), and fullerenes. The voltammetric methods, such as cyclic voltammetry (CV) and differential pulse voltammetry (DPV), have been proven to be potential methods for determining food contaminants. The use of carbon-based electrodes has the added advantage of electrochemically sensing the food contaminants due to their excellent sensitivity, specificity, large surface area, high porosity, antifouling, and biocompatibility.
