Investigation into MoTe2 based Dielectric Modulated AMFET Biosensor for Label-free Detection of DNA including Electric Variational Effects

Due to limitations of Silicon, Transition metal dichalcogenides (TMD) based biosensors are popular in the recent times. In TMD family, Molybdenum telluride (MoTe2) is being studied a lot for different biosensing application. However, for DNA detection using TMD based DMFET, the effect of the electrical variations in DNA has not been studied before. Also, the impact of DNA-Electrode interaction on transducer level of DMFET is yet to be studied. In this article, we have proposed a Molybdenum telluride (MoTe2) based Accumulation Mode Field Effect Transistor (AMFET) for possible dielectric modulated biosensing application. The study is focused on DNA detection including the electric variations of DNA due to surface interaction. We have done a circuit level analysis of the proposed structure for having deeper insights into its performance under various DNA orientations in the nanogap. We have also presented a benchmarking to highlight the superior sensitivity of the proposed structure (ΔVth = 700mV at K =8). The impact of back-gate bias is also included. We have obtained significant variation of threshold voltage shift for different orientation in the proposed structure suggesting strong impact of electrical variations in DNA in biosensing performance of MoTe2 AMFET.

Microbial Fuel Cell: Recent Developments in Organic Substrate Use and Bacterial Electrode Interaction

A new bioelectrochemical approach based on metabolic activities inoculated bacteria, and the microbial fuel cell (MFC) acts as biocatalysts for the natural conversion to energy of organic substrates. Among several factors, the organic substrate is the most critical challenge in MFC, which requires long-term stability. The utilization of unstable organic substrate directly affects the MFC performance, such as low energy generation. Similarly, the interaction and effect of the electrode with organic substrate are well discussed. The electrode-bacterial interaction is also another aspect after organic substrate in order to ensure the MFC performance. The conclusion is based on this literature view; the electrode content is also a significant challenge for MFCs with organic substrates in realistic applications. The current review discusses several commercial aspects of MFCs and their potential prospects. A durable organic substrate with an efficient electron transfer medium (anode electrode) is the modern necessity for this approach.

Experimental Investigation on Centreless Electro Discharge Texturing of Thin Walled Inconel-600 Tubes

Electro discharge texturing is a texture fabrication technique. Inconel 600 has poor machinability in conventional processes due to its poor thermal conductance, high temperature strength, and work hardening nature. In this work, a centreless electro discharge process is employed to produce texturing on the external surfaces of circular tubes by using graphite electrode. Centreless work support and drive attachment was developed and adopted on ENC-35 EDM to perform experiments. This article details the experimental findings of the influence of four process parameters: peak current, gap voltage, pulse on time, and electrode interaction area on material removal rate, tool wear rate and surface roughness. Response surface methods and ANOVA techniques were employed for data analysis while the RSM's desirability approach was used to solve the multi-response optimization. A confirmation run is conducted by adjusting the variables at optimal level within the selected range. Conclusions are drawn for optimum parametric settings.
