Shape-encoded dynamic assembly of mobile micromachines

Field-directed and self-propelled colloidal assembly can be used to build micromachines to perform complex motions and functions, although their integration as heterogenous components with specified structures, dynamics and ...

Supercapacitors turbocharged by laxatives

An international team of scientists, including a professor of chemistry from the University of Bristol, has worked out a way to improve energy storage devices called supercapacitors, by designing a new class of detergents ...

Researchers discover a new phase in block copolymers

All matter consists of one or more phases—regions of space with uniform structure and physical properties. The common phases of H2O (solid, liquid and gas), also known as ice, water and steam, are well known. Similarly, ...

Sheaths drive powerful new artificial muscles

Over the last 15 years, researchers at The University of Texas at Dallas and their international colleagues have invented several types of strong, powerful artificial muscles using materials ranging from high-tech carbon ...
