Improved 3-D nanoprinting technique to build nanoskyscrapers

Nanowalls, nanobridges, nano "jungle gyms": It could seem like the description of a Lilliputian village, but these are actual 3-D-printed components with potential applications in nanoelectronics, smart materials and biomedical ...

Liquid flow is influenced by a quantum effect in water

Researchers at EPFL have discovered that the viscosity of solutions of electrically charged polymers dissolved in water is influenced by a quantum effect. This tiny quantum effect influences the way water molecules interact ...

Fish-inspired material changes color using nanocolumns

Inspired by the flashing colors of the neon tetra fish, researchers have developed a technique for changing the color of a material by manipulating the orientation of nanostructured columns in the material.

Controlling the crystal size of organic semiconductors

Recently, solution-processable organic semiconductors are being highlighted for their potential application in printed electronics, becoming a feasible technique to fabricate large-area flexible thin film at a low cost. The ...

A tango with tangled polymers

While statisticians are driven by real-world problems, U of S mathematics professor Chris Soteros is motivated by the more esoteric behaviour of long-chain molecules, such as polymers and DNA, and the mathematical problems ...

Collective disentanglement of entangled polymers

LMU researchers have disproven the conventional theory used to explain the dynamics of polymer solutions. They show that for biopolymers collective effects facilitate chain mobility, which is reminiscent of the behavior of ...

Precisely defined polymer chains now a reality

Manufactured polymers are ubiquitous in the market. These large molecules are used for synthetic clothing, rubbers and glues, and anything made of plastic. However, the material properties exhibited by man-made polymers rely ...

Saving the planet with flexible electronics

"My research on organic photovoltaic (OPVs) devices reflects my fascination with electronic gadgets and concerns about the environment," says Varun Vohra, tenure-track assistant professor at the Department of Engineering ...

Revealing polymeric fluids behavior at the microscopic scale

An important concept in future healthcare is the development of devices called "lab on a chip." These "chips," not related to the electronic ones found in computers, are small devices in which biological fluids – blood ...
