Biodegradable plastic production. Technicians working on the production of Mater-Bi, a biodegradable plastic produced by the Italian materials company Novamont. Mater-Bi is made from a mixture of renewable raw materials from agriculture, such as non-genetically modified corn-starch, and synthetic polymers. It can be completely metabolised (broken down) by soil micro-organisms, without producing pollutants.

This scanning electron microscope image shows a corallike polymer structure that formed when a polyhydroxyalkanoate polymer scaffold for growing calcium phosphate crystals unexpectedly crystallized with itself. Before imaging, the polymer structures were transferred onto carbon-coated copper grids and sputtered with silver.
Luncheon attendees also heard a brief presentation from LMD Scholarship recipient Jarrett Losecke, Iowa State University.

Scientists at PNNL have created a new family of nanotubes that are composed of peptide-like molecules called peptoids. These nanotubes start out as small droplets that come together to form a cell-membrane-like sheet. Then the sheet folds at one end and zips closed into a tube.

The alligator’s body is covered in scales made of the same material as bone. The scales are connected by collagen fibers, which make the animal’s carapace flexible. A cross-section of the scales shows that they are made of a sandwich-like structure, with an extremely porous layer between two layers of hard bone.
