With its self-healing properties, the PBS coating offers a much more stable performance in terms of capacity compared to a bare anode or one coated with PVDF, a polymer commercially used in lithium-ion batteries. Tejkiran Pindi Jayakumar, who were completing a doctoral course at JAIST at the time, is published in ACS Applied Energy Materials.

The new material is a porous coordination polymer (PCP, also known as MOF; metal-organic framework), a framework consisting of zinc metal ions. Here, we present a dynamic porous coordination polymer (PCP) material with local flexibility, in which the propeller-like ligands rotate to permit CO 2 trapping.

Using particulate methane monooxygenase (pMMO), the researchers created a biocatalytic polymer material that converts methane to methanol. The enzymes retain up to 100% activity in the polymer construct. Remarkably, the enzymes retain up to 100 percent activity in the polymer. a) Schematic of PEG-pMMO hydrogel fabrication.

The team, led by scientists from Harvard University and Lawrence Livermore National Laboratory, employed a microfluidic assembly technique to produce microcapsules that contain liquid sorbents encased in highly permeable polymer shells. The polymer microcapsules are then heated to release absorbed CO 2 for subsequent collection.

The new polymer binder allows a doubling in capacity compared to a conventional lithium-sulfur battery, even after more than 100 charge cycles at high current densities. Without this information, rational design principles for polymer binders remain obscure. Click to enlarge. —Li et al. The new binder goes a step further.
