The history of science sometimes reads like a detective novel. The personal destinies sometimes lead to the fact that outstanding, ingenious works which were decades ahead of their time, sink into oblivion. This seems to […]
Friction is a part of everyday life. Most of us do not think about friction at all, except perhaps when we are trying to push something heavy along the floor, cursing the friction that it […]
Electric vehicles, while often considered a new phenomenon, have existed since the 1800s. At that point in time, electric vehicles outnumbered gasoline powered vehicles for many reasons. Electric vehicles did not have the same vibration, […]
The earth seems to be fairly solid as we stand on its surface. We stand on solid ground and do not sink through the floors in our homes. However, underneath that solid-looking crust are layers […]
The field of nanofluidics is the study of the behavior, control and manipulation of fluids that are confined in extremely small structures. The dimensions of these minute structures typically range from 1 nanometer to 100 […]
Nature continues to shed light on the amazing and wide range of mechanisms employed in the world of plants and animals. Nanoscale (1 x 10 -7 or 3.937 x 10-8 inches) textured surfaces help insects […]
Energy harvesting (also sometimes called scavenging) is a process of energy derivation from the ambient sources, e.g., sunlight, wind, heat, mechanical vibrations, etc. The main idea is that devices can collect the energy present in […]
Origin of sliding friction: role of lattice trapping The friction force acting on a block sliding on a substrate is usually nearly velocity independent unless the sliding speed is so low that thermal activation is […]
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 […]
