Abstract Research investigations conducted in the past has shown that conventional petroleum based lubricants can be replaced with vegetable lubricants. Vegetable oil do not pollute environment, as they are biodegradable. In this investigation, pongamia pinnata was used lubricant, to during turning experiments. The physico chemical properties of modified were evaluated. Ag Nanoparticles incorpo...

The electrification of an electrolyte solution in a nanoporous alloy is investigated through a mechanoelectricity measurement experiment. As the liquid flows across the nanoporous electrode, charge separation occurs over the large nanopore surface, resulting in a significant output voltage, which is in-phase with the actuator motion. This phenomenon is different from the conventional streaming ...

A novel net shape manufacturing method known as SLSIHIP that combines the strengths of selective laser sintering (SLS) and hot isostatic pressing (HIP) is presented. Direct selective laser sintering is a rapid manufacturing technique that can produce high density metal components of complex geometry with an integral, gas impermeable skin. These components can then be directly post-processed to ...

A Magyar Országgyűlés 2019. december 11-én elfogadott határozata a költő, hadvezér és had tudós Zrínyi Miklós (1620–1664) születésének 400. évfordulója alkalmából 2020-as esztendőt Emlékévvé nyilvánította. COVID-19 koronavírus járvány miatti vészhelyzet tervezett rendezvények megemlékezések megtartásának java részét nem, vagy csak 2021-re áthúzódva tette lehetővé, az évforduló mégsem múlt el ny...
