Shining, Colored LED Lighting on Microalgae for Next-Generation Biofuel

As biofuels continue to present challenges, microalgae are gaining momentum as a biofuel energy crop. In the Journal of Renewable and Sustainable Energy, researchers show how a combination of monochromatic red and blue LED illumination on one type of microalga can enhance its growth and increase the biosynthesis of critical components, such as lipids, for microalgae feedstock development. The researchers focused on Dunaliella salina, typically extracted from sea salt fields and found in salt lakes.

Plant-Based Spray Could be Used in N95 Masks and Energy Devices

Engineers have invented a way to spray extremely thin wires made of a plant-based material that could be used in N95 mask filters, devices that harvest energy for electricity, and potentially the creation of human organs. The method involves spraying methylcellulose, a renewable plastic material derived from plant cellulose, on 3D-printed and other objects ranging from electronics to plants, according to a Rutgers-led study in the journal Materials Horizons.
