Diamagnetically levitated nano positioners with large-range and multiple degrees of freedom
Precision positioning stages are indispensable in many branches of science and engineering, where they are employed for imaging, manipulation, fabrication, and material characterization. Compact, multi-degree-of-freedom ...
Synergetic effect of electrostatic gating and interfacial states in molecular switching operation in molybdenum disulfide based thin hetero-interfaces
Nowadays, two-dimensional (2D) materials have stimulated intensive research due to their intriguing physical properties and excellent electronic application. van der Waals (vdW) semiconductors are attractive for electrically ...
Design and Development of Novel Fiber Bragg Grating based devices for various Biomedical applications
Sensors have always been an integral part of human life. Apart from the numerous inherent sensors which the human body possesses, there are various man-made sensors which has been studied and implemented widely to fulfill ...
Carbon nanomaterials for energy and environmental applications
Environmental pollution and energy storage are two important issues in the modern day society. In this regard, Carbon nanomaterials have attained immense importance, due to their high surface area and electrical conductivity ...
Development of Cryocooler Based High Performance Cryosorption Pump
The aim of this work is to develop high performance cryosorption (or cryoadsorption) pumps specifically for fusion applications. An actual cryopump for the above application will use the supercritical liquid helium flow ...
Development of Graphene Palladium Nanocomposite based Flexible Sensors for Strain and Temperature Measurement
In recent years, device manufacturing technology has been shifted from bulk and thin-film materials to nanomaterials, which are emerged as a unique class of materials. Among all the two-dimensional (2D) nanomaterials, ...
A Platform for Handheld Ultrafast PCR
The Polymerase Chain Reaction (PCR) is one of the most sensitive and specific diagnostic tools available today. Yet, it stands out of reach for many vulnerable populations because commercial solutions are expensive, bulky, ...
Deep learning methods for light fluence compensation in two-dimensional and three-dimensional photoacoustic imaging
Photoacoustic imaging (PAI) employed the special properties of light or photons to obtain
detailed images of organs, tissues, cells, and even molecules. The method allowed for a
non-invasive or minimally invasive examination ...
