An adaptive-focus lens is a device that is capable of tuning its focal length by means of an
external stimulus. Numerous techniques for the demonstration of such devices have been …

Self-assembly offers unique possibilities for fabricating nanostructures, with different
morphologies and properties, typically from vapour or liquid phase precursors. Molecular …

This work presents a “refractive index” sensor based on “photonic crystal fiber” and “surface
plasmon resonance” phenomenon. A combination of Gold (Au) with Titanium Nitride (TiN) is …

Oil and gas (O&G) explorations moving into deeper zones for enhanced oil and gas
recovery are causing serious safety concerns across the world. The sensing of critical …

Temperature, salinity, and pressure (TSP) are essential parameters for the ocean. Optical
fiber sensors (OFSs) have rapidly come into focus as an ocean detection technology in …

The standard rapid approach for the diagnosis of coronavirus disease 2019 (COVID-19) is
