Heat transfer in a partially-filled, rotating inclined pipe with water flowing through it is experimentally investigated. The test section is a 1000 mm long stainless steel pipe with 32.8 mm inner diameter and 1.1 mm wall thickness. The outer wall is painted black to improve its emissivity. The outer wall temperature distribution is captured using ...
To utilize synergetic effect of graphene's higher conductivity and magnetic nanoparticles biocompatibility, an electrochemical nanobiosensor is constructed based on magnetic nanoparticle decorated graphene (MRGO) using Horseradish peroxidase (HRP) for H2O2 sensing. Sensors based on magnetic nanoparticles (MNP) and reduced graphene oxide (RGO) are s...

In this study, we report a deep red emissive organic crystal that displays high contrast fluorescence switching under mechanical and thermal stimulation. Upon mechanical grinding, the pristine red emissive crystals of 1R ((em) = 667 nm) transformed into green emissive crystalline powder ((em) = 550 nm) with a remarkable hypsochromic shift of wavele...
Single phase heat transfer in a partially-filled, rotating horizontal pipe with axial liquid (water) flow is studied in this work. Thermal imaging is used to capture outer wall temperature of the partially filled rotating heated pipe. Local heat transfer coefficient along the length of the rotating pipe is calculated. Various parameters influencing...

In the present work, bismuth iron oxide-graphene composite has been explored as electrode material for electrochemical supercapacitor application. Bismuth iron oxide (BFO) nanoparticles, synthesized by sol-gel process, are mixed with the graphene sheets in a solution. The electrodes are prepared by coating the resulted slurry on stainless steel (SS...

Catalytic oxidation of ferrous sulfate with molecular oxygen in 0.5 M H2SO4 has been studied on carbon supported platinum catalyst. Analysis of this catalytic chemical reaction as two distinct electrochemical half reactions proceeding on the catalyst surface is presented. Further, it is proposed that the catalytic chemical reaction can be studied b...
In this study, we report a synthetically simple donor-acceptor (D-A)-type organic solid-state emitter 1 that displays unique fluorescence switching under mechanical stimuli. Orange and yellow emissive crystals of 1 (1O, 1Y) exhibit an unusual "back and forth" fluorescence response to mechanical force. Gentle crushing (mild pressure) of the orange o...
