This talk is addressed to describe the use of thermal evaporation of transition metals to fabricate metal thin films. Film thickness control is precisely achieved through modulation of the Z-position (metal source-to-substrate distance). Then, the metal grain size ) is strongly c [....] » Read More
Shape memory alloys take place in a class of advanced smart materials by exhibiting dual memory characteristics, Shape Memory Effect and Superelasticity. Shape memory effect is initiated with thermomechanical processes on cooling and deformation and performed thermally on heating [....] » Read More
The growing demand for sustainable and environmentally safe materials has led to increased interest in green nanotechnology and biodegradable packaging systems. In the present work, silver nanoparticles (AgNPs) were synthesized using green tea extract, which acted as a natural re [....] » Read More
Title : Ferrofluid mediated synthesis of nanomagnetic polymer materials in supercritical fluids
M G H Zaidi, G B Pant University of Agriculture & Technology, India
Nanomagnetic polymer materials (NPMs) offers broad spectrum of applications in diagnostics, drug delivery, environmental cleanup, sensors, actuators and electromagnetic interference. MPMS are routinely synthesized through reactive or non reactive routes in presence of solvents. A [....] » Read More
Title : Thermodynamic analysis of a combined modified kalina–GT-MHR cycle with porous medium effects
Rakesh Manilal Harjivandas Patel, Government Science College, Gandhinagar, India
Efficient utilization of waste heat in advanced nuclear power systems has become a major research focus in modern energy engineering. This study proposes a novel thermodynamic configuration that integrates a Modified Kalina Cycle (KC) with a Gas Turbine–Modular Helium React [....] » Read More
Title : Non-newtonian rheology on curved circular squeeze films using the Rabinowitsch fluid model
Rakesh Manilal Harjivandas Patel, Government Science College, Gandhinagar, India
Squeeze film lubrication plays a crucial role in many mechanical systems such as gear mechanisms, thrust bearings, artificial joints, and clutch plates. Classical lubrication studies often assume Newtonian fluids; however, modern lubricants frequently exhibit non-Newtonian rheolo [....] » Read More
