Oznake: grafenske kvantne pike;super mazljivost;mejno mazanje;vodni glicerol;zelena tribologija;jeklo;graphene quantum dots;superlubricity;boundary lubrication;aqueous glycerol;green tribology;steel;
Achieving macroscale superlubricity on engineering steel by utilizing aqueous green lubricants has gained growing interest, given its substantial potential to reduce energy consumption and carbon footprint. However, maintaining superlubricity under diverse sliding conditions over a prolonged duratio ...

Super-low friction and wear in steel contacts enabled by tribo-induced structural degradation of graphene quantum dots
Irfan Nadeem, Bojan Ambrožič, Goran Dražić, Janez Kovač, Albano  Cavaleiro, Mitjan Kalin
Izvirni znanstveni članek
Oznake: materiali;grafen;kvantne pike;tribologija;trenje;obraba;materials;graphene;quantum dots;tribology;friction;wear;
Reducing friction is a promising strategy to decrease material losses and energy consumption in industrial systems. However, in aqueous-lubricated steel contacts, the contact pressure rarely exceeds 50 MPa during super-low friction due to excessive wear. This work demonstrates that even in steel/ste ...

Superior macro-scale tribological performance of steel contacts based on graphene quantum dots in aqueous glycerol
Irfan Nadeem, Matjaž Malok, Janez Kovač, Talha Bin Yaqub, Albano  Cavaleiro, Mitjan Kalin
Izvirni znanstveni članek
Oznake: grafen;grafenske kvantne pike;grafit;vodni glierol;super nizko trenje;zelena tribologija;graphene;graphene quantum dots;graphite;aqueous glycerol;super-low friction;green tribology;
Reducing friction is one of the best ways to lower energy consumption and make processes more environmentally friendly. Because of the growing interest in green lubricants, we investigated the synergetic effects of graphene quantum dots (GQDs) combined with aqueous glycerol to improve the lubricatio ...

ǂA ǂreview on gasification and pyrolysis of waste plastics
Hamad Hussain Shah, Muhammad Amin, Amjad Iqbal, Irfan Nadeem, Mitjan Kalin, Arsalan Muhammad Soomar, Ahmed M. Galal
Pregledni znanstveni članek
Oznake: uplinjanje;piroliza;plastični odpadki;valorizacija;kemija;gasification;pyrolysis;plastic waste;valorization;chemistry;
Gasification and pyrolysis are thermal processes for converting carbonaceous substances into tar, ash, coke, char, and gas. Pyrolysis produces products such as char, tar, and gas, while gasification transforms carbon-containing products (e.g., the products from pyrolysis) into a primarily gaseous pr ...
