In a recent study published in Science Advances, materials scientists Julie A. Jackson and colleagues presented a new class of materials architecture called field-responsive mechanical metamaterials (FRMM). The FRMMs exhibit ...
Oxygen is an abundant element that can form undesired impurities or ceramic phases in metallic materials, while doping the element on metal can render substrates brittle. During interactions with metallic alloys, oxygen takes ...
In a recent study conducted by Hongri Gong and colleagues, a respiratory supercomplex was isolated from the bacterium Mycobacterium smegmatis, and its structure was visualized at a resolution of 3.5 Å using cryo-electron ...
Biological materials from bone to spider-silk and wood are lightweight fibre composites arranged in a complex hierarchical structure, formed by directed self-assembly to demonstrate outstanding mechanical properties.
The complex architecture of bone is challenging to recreate in the lab. Therefore, advances in bone tissue engineering (BTE) aim to build patient-specific grafts that assist bone repair and trigger specific cell-signaling ...
Reversible shape change is a highly desirable property for many biomedical applications, including mechanical actuators, soft robotics and artificial muscles. Some materials can change size or shape when irradiated with light, ...
As living organisms eat, grow, and self-regenerate, all the while they are slowly dying. Chemically speaking, this is because life is thermodynamically unstable, while its ultimate waste products are in a state of thermal ...
Nested structures are commonly found throughout nature and art, whether they be in the form of tree rings, Russian dolls, or Wassily Kandinsky's famous 1913 abstract painting Color Study: Squares with Concentric Circles. ...
When trying to understand the origins of life on Earth, researchers run into a paradox: while water is an indispensable solvent for all known life forms that exist today, water also inhibits the formation of string-like chains ...
By designing a solid electrolyte that is rigid on one side and soft on the other, researchers have fabricated a lithium-metal battery that completely suppresses dendrite formation—a major safety hazard that can cause fires ...
