All plastic waste could become new, high-quality plastic through advanced steam cracking

A research group has developed an efficient process for breaking down any plastic waste to a molecular level. The resulting gases can then be transformed back into new plastics – of the same quality as the original. The new process could transform today's plastic factories into recycling refineries, within the framework of their existing infrastructure.

Calcium batteries: New electrolytes, enhanced properties

Calcium-based batteries promise to reach a high energy density at low manufacturing costs. This lab-scale technology has the potential for replacing lithium-ion technology in future energy storage systems. Using the electrolytes available, however, it has been impossible so far to charge calcium batteries at room temperature. Researchers of Karlsruhe Institute of Technology (KIT ) now present a promising electrolyte class, with which this will be possible.

Watching energy transport through biomimetic nanotubes

Scientists have investigated a simple biomimetic light-harvesting system using advanced spectroscopy combined with a microfluidic platform. The double-walled nanotubes work very efficiently at low light intensities, while they are able to get rid of excess energy at high intensities. These properties are useful in the design of novel materials for the harvesting and transport of photon energy.

A new strategy for the synthesis of complex natural products

Chemists have succeeded in synthesizing two complex natural products from the group of dithiodiketopiperazines (DTPs). For this, they employed a new strategy based on ''C-H bond activation,'' resulting in a short and high yielding route. The researchers describe their new concept for the total synthesis of Epicoccin G and Rostratin A.
