capable of generating electricity on glass and flexible plastics, today announced that its technology has set a new record for generating electricity
which generates electricity on see-through glass and flexible plastics with colored tints popular to skyscraper glass.
Rogers says the whole system is about as stiff as the plastic used to make food wrappers.
In addition, because many of these materials are derived plastics from fossil fuels, they also increase the impact on climate change.
With the above in mind, a European research project has developed new environmentally friendly materials that can replace oil-based plastic films used in packaging for food
These materials can compete with plastic films and other flexible packaging in terms of performance and cost, but have a much lower environmental impact.

or even plastics. Fischer-Tropsch derived fuels are certified already and can be used by existing vehicles and aircraft without modifications of their engines or of fuel infrastructure.
A polymer is a type of large molecule that forms plastics and other familiar materials. he field is rather immature it s in the infancy stagesays Luping Yu a professor in chemistry at the University of Chicago.

The light in these terahertz wavelengths can pass through materials that we normally think of as opaque such as skin plastics clothing and cardboard.
"The researchers place the nanowires on the Shrinky Dinks plastic as they would for any other substrate,
"The plastic is clamped before baking so that it only shrinks in one direction, so that the wires pack together
The researchers also can control how densely the wires pack by varying the length of time the plastic is heated.
They also are exploring using lasers to precisely shrink the plastic in specific patterns. Nam first had the idea for using Shrinky Dinks plastic to assemble nanomaterials after seeing a microfluidics device that used channels made of shrinking plastic.
He realized that the high degree of shrinking and the low cost of plastic could have a huge impact on nanowire assembly and processing for applications."
"I'm interested in this concept of synthesizing new materials that are assembled from nanoscale building blocks, "Nam said."

How it worksthe nanoparticles are prepared from molecules (synthetic macromolecules commonly called plastics) that have a protective,
which in turn is a building block for polylactic acid. According to co-author Professor Bert Sels of hape-selective zeolite catalysis for bioplastics productionthe production process for PLA is expensive because of the intermediary steps."
"First, lactic acid is fed into a reactor and converted into a type of pre-plastic under high temperature and in a vacuum,
The pre-plastic-a low-quality plastic-is broken then down into building blocks for PLA. n other words,
you are first producing an inferior plastic before you end up with a high-quality plastic. And even though PLA is considered a green plastic,
the various intermediary steps in the production process still require metals and produce waste.""The KU Leuven researchers developed a new technique by applying a petrochemical concept to biomass."
LA will never fully replace petroleum-based plastics. For one thing, some objects, such as toilet drain pipes, are meant not to be biodegradable.
they have identified a few promising copper multi-metallics with a higher energy conversion efficiency and possibly higher selectivity in carbon dioxide electro-reduction to ethylene, an extremely useful chemical in industry for making plastics.

The same design principle can be extended easily to other materials beyond silicon, such as metals, glass ceramics and plastics.

We have a plastic that s alive a living polymer. Our vision is to replace plastics where ever they don t make sense

It's like a conventional plastic, but it s alive. It has a five-day growth period.

Compared to other polymers like plastics, the wood nanomaterial is biocompatible and has relatively low thermal expansion coefficient,
#Producing biodegradable plastic just got cheaper, greener Biodegradable drinking cups or vegetable wrapping foil: the bioplastic known as polylactic acid (PLA) is already a part of our everyday lives.
And yet, PLA is considered not yet a full alternative to traditional petroleum-based plastics, as it is costly to produce.
Researchers from the KU Leuven Centre for Surface Chemistry and Catalysis now present a way to make the PLA production process more simple and waste-free.
which in turn is a building block for polylactic acid. PLA degrades after a number of years in certain environments.
PLA is also one of the few plastics that are suitable for 3d printing. However, PLA is not yet a full alternative for petroleum-based plastics due to its cost.
The production process for PLA is expensive because of the intermediary steps.""First, lactic acid is fed into a reactor and converted into a type of pre-plastic under high temperature and in a vacuum,
"Professor Bert Sels explains.""This is an expensive process. The pre-plastic--a low-quality plastic--is broken then down into building blocks for PLA.

Of course, PLA will never fully replace petroleum-based plastics. For one thing, some objects, such as toilet drain pipes, are meant not to be biodegradable.
And it is not our intention to promote disposable plastic. But products made of PLA can now become cheaper and greener.
so Bailie did it manually. e used a sheet of plastic with silver nanowires on it, he said. hen we built a tool that uses pressure to transfer the nanowires onto the perovskite cell, kind of like a temporary tattoo.
