Nonuniform proton flux around a reactive Janus particle as a result of zone selective heterogeneous surface reaction leads to the formation of asymmetric electrical double layers (EDLs) which assists in generating a proximate electric field dipole around the Janus particle to initiate autoelectrophoretic migration. To estimate the force of the auto...

We report the synthesis of gold nanotwins (Au NTs) on a solid and transparent glass substrate which in turn has been employed for the selective optoplasmonic detection of Escherichia coli (EC) bacteria in human urine for the point-of-care diagnosis of urinary tract infections (UTIs). As compared to the single nanoparticle systems (Au NPs), the Au N...

Electrochemical reforming of alkaline ethanol has been found to be an attractive single‐step method at room temperature and pressure for hydrogen (H2) production especially when the electrical energy has been supplied through non‐fossil fuel resources. In the present study, we employ solar panels to generate and allow a low‐voltage current to flow...

Substantial advancements have been observed over the years in the research and development of Localized Surface Plasmon Resonance (LSPR). A variety of current and future applications involving anisotropic plasmonic nanoparticles include biosensors, photothermal therapies, photocatalysis, and various other fields. Amongst various other applications,...

The chemistry underlying the storage phenomena in batteries and supercapacitors has been known to mankind for quite some time now. Nonetheless, a holistic apprehension of their rudimentary characteristics throughout their lifetime and beyond is imperative to accentuate their maximum potential. Although numerous reviews have addressed many of the fa...

Hypothesis The formation of virus-laden colloidal respiratory microdroplets – the sneeze or cough virulets and their evaporation driven miniaturization in the open air are found to have a significant impact on the community transmission of COVID–19 pandemic. Simulation Details We simulate the motions and trajectories of virulets by employing lamina...

This chapter focuses on various materials and methods employed for biosensing technologies, followed in recent times. Biosensing is a crucial practice of the identification of different diseased conditions of human health. A biosensor is a tool that uses a biological element like an antibody, enzyme, nucleic acid, cells, and microorganisms to detec...

This work uncovers the effects of component diffusivities, local convection, and reaction kinetics on cyclic voltammetry (CV). A finite element-based software, COMSOL Multiphysics, is used for the simulation employing species transport equation, electrode reaction with Faraday's law, and Butler Volmer equation. All the calculations are done taking...

The present work focuses on the non-conventional design and operation of micro fuel cells. Two different kinds of fuel cells, Proton Exchange Membrane (PEM) and Biological Fenton (BF) based fuel cells, are fabricated to harvest energy. For the PEM fuel cell, H2 and O2 are generated by Mg/HCl reaction and Fenton's reaction respectively, and are subs...

The chapter explores various synthesis pathways, characterization, and biosensing applications where gold nanoparticles (Au NPs) have been employed abundantly. The chapter is organized with piecewise discussions on several processes of Au NPs synthesis, characterization, the factors that guide the size of Au NPs during synthesis, and the details on...

The present study focuses on the component transfer from one liquid phase to another liquid phase, commonly known as the extraction process, performed in a microchannel in the presence of spontaneous interfacial convection, driven by either an interfacial tension gradient or an applied external electric field. Marangoni instability occurs as a resu...
