2D materials deserved an interest in material science and other disciplines due to their exciting electronic, mechanical, and optical properties. The unique behavior of these materials originate from very strong in-plane atoms interactions and very […]
Hardness is a material’s resistance to plastic deformation and this property is widely used to rank materials for various engineering applications. Hard materials can be used for cutting, drilling. Hardness frequently correlates with wear resistance […]
Most of the natural or engineered surfaces are not perfect, meaning they are rough. The surface roughness was found across many scales: from atomic to tectonic. The earth looks smooth from space, but someone standing […]
The famous picture of transportation of an Egyptian statue to the grave of Tehuti-Hetep, El-Bersheh indicates that the concept of lubrication was already known to ancient Egyptians. The picture below shows how the slaves are […]
The internet is full of videos of people having fun running over white slime. It almost looks as if they were walking on water. But when they stand still, they slowly begin to sink. The […]
Researchers at KTH have produced a bio-based material that is reported to surpass the strength of all known bio-based materials whether fabricated or natural, including wood and spider silk. Working with cellulose nanofibre (CNF), the […]
Experiments with levitated nanoparticles reveal role of friction at the nanoscale Transitions occurring in nanoscale systems, such as a chemical reaction or the folding of a protein, are strongly affected by friction and thermal noise. […]
Forty years ago, MIT emeritus professor of mechanical engineering Ernest Rabinowicz calculated that 6 percent of the annual U.S. gross domestic product was lost through mechanical wear. His assertion gained enough traction that it became […]
A group of researchers from Queen’s University Belfast have discovered a stretchy miracle material that could be used to create highly resistant smart devices and scratch-proof paint for cars. Led by Dr Elton Santos from […]
New research indicates how static electricity puts the charge in material, offering answer to centuries-old question For centuries, scientists have tried to understand triboelectric charging, commonly known as static electricity. Triboelectric charging causes toner from […]
