Plastic to combat pollution.
Biodegradable plastics are better for the environment, but their rapid degradation means they can’t be recycled. Researchers from the University of Canterbury have developed a method to convert the plastics to a foam that can be reused for insulation or flotation devices.
Their method is described in the journal Physics of Fluids: https://aip.scitation.org/doi/10.1063/5.0050649

Recycling and rheology of poly(lactic acid) (PLA) to make foams using supercritical fluid
Biodegradable plastics are thought to be the possible directions in managing plastic pollutions. Unfortunately, they are not recycled in most countries since they are designed to decompose even tho...
Recycling electric vehicle batteries.
University of Leicester researchers have developed an ultrasonic delamination technique to controllably separate the different metals used in lithium-ion batteries, improving the yield and purity of the recovered materials.
Their analysis is detailed in Green Chemistry: http://dx.doi.org/10.1039/D1GC01623G

Lithium ion battery recycling using high-intensity ultrasonication
Decarbonisation of energy will rely heavily, at least initially, on the use of lithium ion batteries for automotive transportation. The projected volumes of batteries necessitate the development of fast and efficient recycling protocols. Current methods are…

A Reverse Approach to the Total Synthesis of Halichondrin B
A new strategy is described for the total synthesis of halichondrin B featuring reversal of the sequential construction of a number of its cyclic ethers from the classical approach by instead forming C–O bonds first followed by C–C bond formation. Employing…
3D printing with functional gels.
A study from Dartmouth College describes a process using heat to change the arrangement of molecular rings on a chemical chain creates 3D-printable gels with a variety of functional properties. Printing objects with different mechanical strengths using a single ink could replace the costly and time-consuming use of multiple inks for printing.
The results are published in the journal Chem: http://dx.doi.org/10.1016/j.chempr.2021.06.004
