Imprinted Color Patterns

Azopolymer material allows light-assisted imprinting of nanostructures for structurally colored surfaces

17-Jan-2020

Structural colors appear because the imprinted pattern on a surface changes the wavelengths of light. Chinese scientists have introduced an azopolymer that allows the imprinting of nanopatterns in a novel room-temperature lithographic process. A key aspect of the technique is the light-induced ...

Pretty with a twist

Complex, porous, chiral nano-patterns arise from a simple linear building blocks

17-Jan-2020

Nanoscience can arrange minute molecular entities into nanometric patterns in an orderly manner using self-assembly protocols. Scientists at the Technical University of Munich (TUM) have functionalized a simple rod-like building block with hydroxamic acids at both ends. They form molecular ...

A new 'cool' blue

Inexpensive, durable and more environmentally friendly

17-Jan-2020

Throughout history, people have sought vibrant blue pigments. The Egyptians and Babylonians used lapis lazuli 6,000 years ago. In 1802, a French chemist synthesized cobalt blue. More recently, in 2009 scientists discovered YInMn Blue, otherwise known as "Oregon Blue." But most of these pigments ...

Not so fast: Some batteries can be pushed too far

Scientists find overabundance of intentional defects can cause battery cathodes to fail

16-Jan-2020

Intentional defects in batteries have given Rice University scientists a window into the hazards of pushing lithium-ion cells too far. New simulations by Rice materials scientist Ming Tang and graduate student Kaiqi Yang, detailed in the Journal of Materials Chemistry A, shows too much stress in ...

How to make it easier to turn plant waste into biofuels

Innovative process to rapidly dissolve plant fibers

16-Jan-2020

Researchers have developed a new process that could make it much cheaper to produce biofuels such as ethanol from plant waste and reduce reliance on fossil fuels. Their approach, featuring an ammonia-salt based solvent that rapidly turns plant fibers into sugars needed to make ethanol, works well ...

Engineers develop 'chameleon metals' that change surfaces in response to heat

15-Jan-2020

Just like a chameleon changes its skin color in response to its environment, engineers have found a way for liquid metal - and potentially solid metal - to change its surface structure in response to heat. Treating particles of liquid metal alloys with heat causes them to roughen their surfaces ...

Man versus machine: Can AI do science?

15-Jan-2020

Over the last few decades, machine learning has revolutionized many sectors of society, with machines learning to drive cars, identify tumors and play chess - often surpassing their human counterparts. Now, a team of scientists based at the Okinawa Institute of Science and Technology Graduate ...
