Self-organisation of bacteria through swarming
Swarming is a unique example of social behaviour in bacteria. They represent the collective
effort of bacteria to translocate on moist substrates. The bacteria extract fluid from the
substrate through osmosis and produces ...
Power Combining of Raman Fiber Lasers
Fiber lasers have become ubiquitous in industry and research for their numerous attractive properties that other lasers such as solid state lasers lack. However, conventional doped fiber lasers, though providing high power, ...
Versatile sensing platform using silicon photonic microring resonators
Measurement of refractive indices of liquids and thin films can play an important
role for chemical analysis in the fields of healthcare and biomedical research.
There is a requirement of miniaturized refractive index ...
Investigation of Growth, Structural and Optical properties of different phases of Ga2O3
Among the semiconducting sesquioxides, Ga2O3 has attracted considerable research attention
in recent years due to its excellent properties, including direct ultra wide band gap, optical
transparency, high excitonic binding ...
Development of High-Performance Piezoelectric Micromachined Transducers for Near Ultrasound
Near-ultrasound refers to sound with frequencies just above the range of human hearing, from about 18 to 40 kHz. This band is rarely used for typical ultrasound applications and is ignored for all except the most demanding ...
Investigation of Au-free AlGaN/GaN HEMT on Silicon with substrate transfer process: From Ohmic contacts to RF performance
The technological importance of III-nitride based high electron mobility transistors (HEMTs) for power switching and RF applications is growing rapidly, owing to two advantageous electrical properties. While high sheet ...
Strain engineering of 2D NEMS for resonant sensing
2D material-based nanoelectromechanical systems have emerged as excellent tools for force measurement with extreme sensitivity levels. Most sensing methods with 2D nanoelectromechanical (2D NEMS) systems utilize frequency ...
Development and Performance Evaluation of the Flapping Wing with In-situ Piezoceramic Actuator
Unmanned Aerial Vehicles (UAV) are essentially automatic flight vehicles having dimensions, wingspan and airspeed, smaller than the conventional aerial vehicles. UAVs are employed widely in applications such as surveillance ...
Scanning Probe microscopy of van der Waals heterostructures and non-equilibrium magnetotransport in graphene
Graphene is a two-dimensional semimetal that has linear dispersion in energy-momentum
space. When graphene is subjected to a perpendicular magnetic field, the dispersion is no
longer linear, resulting in discrete energy ...
Two-dimensional materials based artificial synapses for neuromorphic applications
The need and demand for continuous high-speed, energy-efficient hardware advancement is undisputed. Traditional computing system with von Neumann architecture leads to high energy consumption and latency due to a huge ...
