The basic objective of this review is to furnish extensive confirmation on the bioactive chemical compounds and pharmacological aspects of Nagarmotha, i.e., Cyperus scariosus of the family Cyperaceae and some others plants used to treat various diseases of eyes as mentioned in Ayurveda, Charaka Samhita, and Sushrut Samhita. Nagarmotha showed an extensive ethnomedicinal record and constituted a phytonut Read More

The present time has witnessed a never-before-heard interest in and applications of microfluidic devices and systems. In microfluidic systems, fluid flows and is manipulated in microchannels. Mixing is one of the most important criteria for a majority of microfluidic systems, whose laminar nature hinders the efficiency of micromixing. The interface between the flowing fluid and the inner wall surface of the microchannel greatly infl Read More

Background: Tunnel Field-effect transistor (TFETs) has appeared as a promising candidate due to its steep slope (SS<60 mV/dec), which can be used for low-power applications.Objectives: Authors investigated AlxGa1-xAs as the channel material in Silicon-on-Insulator (SOI) TFETs and compared it to other existing channel materials, SiGe, Ge, Si, Ge, Strained Si, and GaAs.Methods: For the entire device study, the mole fraction x = 0.

Introduction: A new method of modelling surface roughness of the resultant structure from various parameters in the microforming of CNT forests has been developed. One of the top-down microforming methods of CNT forests is called micromechanical bending (M2B). The method uses a high-speed rotating spindle to compact and flatten the surface of CNT forests. It results in the surface structure becoming smoother and Read More

Introduction: Micro-Electrical Discharge Machining (μEDM) is a technique for non-contact machining of conductive or semiconductor materials. It is mainly adapted to machining hard materials. Its principle is based on the creation of electrical discharges between the micro tool and the workpiece, which are immersed in a dielectric. Methods: It is a complementary process to mechanical or laser micromachining techniqu Read More

Introduction: Thermal drifts of MEMS sensors are one of their biggest shortcomings. However, experimental studies may offer a solution while striving for the reduction of related errors.Objective: The aim was to determine the thermal drifts of MEMS accelerometers associated with the offset voltage and the scale factor and then to propose a way of reducing the resultant errors.Methods: Four commercial dual-axis MEM Read More

Introduction: This paper aims to fabricate the high aspect ratio tungsten micro-tools with diameters up to 80 μm by electrochemical etching. This process is simple and easy to develop, but it requires a deep study to achieve the fabrication of micro-tools with a diameter of 5 μm.Methods: In this work, we studied the effect of the pulsed signal parameters used during the electrochemical etching. The parameters studied are V Read More

Background: The technique of approximation allows for a trade-off between accuracy, speed, area use, and power usage. It is essential in applications that can withstand errors because even a modest accuracy loss can have a significant impact on the result.Methods: In this research, a novel approximate adder and exact 3:2 and 4:2 compressors are used to create a power-efficient approximation multiplier. In order to r Read More
