NANOPARTICLES FOR OPTO-ELECTRONICS

Nanomaterials play a significant role in advancing optoelectronics as these show unique properties and functionalities. Also, they have distinct advantages, such as quantum confinement effects, large surface area-to-volume ratio, and tunable optical properties. They are used in various applications, such as light-emitting diodes (LEDs), solar cells, and displays. I used several nanomaterials and those are quantum dots (QDs), nanowires, nanoparticles, plasmonic nanomaterials, nanocomposites, etc.

2D MATERIALS FOR ENERGY

2D materials have shown great potential for various energy-related applications due to their unique properties at the atomic scale. Graphene and other 2D materials, such as transition metal dichalcogenides (TMDs) like MoS2 and WS2, have been investigated for use in solar cells. These materials have been explored for energy storage applications, batteries, and supercapacitors. Chalcogenides have demonstrated excellent catalytic activity for energy conversion processes.

Sensors

A sensor is a device that detects and measures physical properties or changes in its environment and converts this information into signals or data that humans or other systems can interpret. Sensors are widely used in various fields and applications, including consumer electronics, industrial automation, healthcare, environmental monitoring, and more. I am involved in developing several gas sensors, biosensors, water contaminant sensors, and wearable sensors.

DEVELOPEMENT OF HANDHELD DEVICES

A handheld device is a portable electronic tool designed to be compact, lightweight, and easy to carry around, allowing users to perform various tasks on the go. Handheld devices often integrate multiple functionalities, making them versatile and convenient for everyday use for the common man. Recently I have developed a small potentiostat that can be used as a sensor platform. Nevertheless, this can be used as an educational tool for school and college students.
