Ultrasonic transducers using piezoelectric materials are popular among researchers because of the efficiency, ease handling, low weight, and small size. In this research, an ultrasonic wave generator using piezoelectric ...

Nichrome (Ni/Cr) alloys are used in many industrial applications due to their better electrical properties and commercial availability. It is a known fact that these alloys are having a surface passivation layer of chromium ...

Pressure sensors are often used in applications in the areas of direct pressure sensing in weather instrumentation, aircrafts, automobiles, machinery and Altitude sensing in aircraft, rockets, satellites. Development of ...

Dye-sensitized solar cells (DSSCs) use platinum electrode as the counter electrode. In this study, to reduce the overall cost of DSSCs, graphene electrodes were fabricated as an alternative to platinum electrode. Graphene ...

Asphalt is widely used as the road pavement material. Warmer conditions in tropical countries like Sri Lanka, leads to corrugation of asphalt pavements. The main objective of this research is to enhance the thermal stability ...

When electrical pulses are applied to a metal during deformation, the resistance to deformation is dramatically reduced while the plasticity increases significantly. This phenomenon is introduced as electroplasticity. ...

This research work is based on the process optimization of nanocellulose extraction from chemically purified cellulose. Cellulose was extracted from rice straws of BG 352 which contains the highest cellulose percentage ...

During the compression testing of any material sample, the true compressive flow stress of the material cannot be determined due to the presence of friction between the end surfaces of the specimen and platens (of the ...

The objective of this research is to find a method to determine the water-cement ratio that has been used in a concrete during construction, retrospectively. Water-Cement ratio affects the properties of concrete including ...
