Actively swimming gold nanoparticles

Bacteria can actively move towards a nutrient source—a phenomenon known as chemotaxis—and they can move collectively in a process known as swarming. Chinese scientists have redesigned collective chemotaxis by creating ...

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, ...

The similarities between a Van Gogh painting and a golf ball

On a molecular scale, there are surprising similarities between the outer shell of a golf ball and the white oil paint used by Van Gogh and his contemporaries. In both cases, the interactions between zinc ions and polymer ...

Researchers create uniform-shape polymer nanocrystals

A team of researchers from the University of Konstanz has demonstrated a new aqueous polymerization procedure for generating polymer nanoparticles with a single chain and uniform shape, which, by contrast to previous methods, ...

Synthesis of helical ladder polymers

Researchers at Kanazawa University synthesized helical ladder polymers with a well-defined cyclic repeating unit and one-handed helical geometry, as they reported in the Journal of the American Chemical Society.

Working out makes hydrogels perform more like muscle

Human skeletal muscles have a unique combination of properties that materials researchers seek for their own creations. They're strong, soft, full of water, and resistant to fatigue. A new study by MIT researchers has found ...

Radical steps toward clean encapsulation

A polymer with changeable properties and broad applications has been developed at A*STAR. The polymer changes between core-shell nanoparticles, self-assembled agglomerations, and degraded fragments, depending on environmental ...

Researchers tune material's color and thermal properties separately

The color of a material can often tell you something about how it handles heat. Think of wearing a black shirt on a sweltering summer's day—the darker the pigment, the warmer you're likely to feel. Likewise, the more transparent ...

Muscle-like material expands and contracts in response to light

Just as controlled-release medications slowly dole out their cargo after they experience a pH change in the body, implanted "artificial muscles" could someday flex and relax in response to light illuminating the skin. In ...

A novel material for transparent and flexible displays

The next generation of flexible and transparent displays will require a high-performing and flexible polymeric material that has the optical and thermal properties of glass. The material must be transparent to visible light ...
