Newly-Developed Carbon Nanolattices are Stronger than Diamonds

With wall thicknesses of about 160 nm, a closed-cell, plate-based nanolattice structure is the first experimental verification that such arrangements reach the theorized limits of strength and stiffness in porous materials. Image credit: Cameron Crook & Jens Bauer, University of California, Irvine.

An international team of scientists has created carbon nanolattices — constructed from closed-cell plate-architectures — that are stronger than diamonds as a ratio of strength to density. With wall thicknesses of about 160 nm, a closed-cell, plate-based nanolattice structure is the first experimental verification that such arrangements reach the theorized limits of strength and stiffness in porous materials.

Raman et al highlighted the remarkable possibility and potential of generating small amounts of power by radiative cooling at night using low-cost, off-the-shelf, commodity components (less than $30 USD for the initial proof of concept demonstration). In off-grid locations throughout the world, this approach of generating light from darkness highlights an entirely new way of maintaining lighting, entirely passively, at night. The power generated could also be used to power small sensors in remote locations, with their lifetimes not being limited by batteries but the lifetime of the thermoelectric module, which can be an order of magnitude longer.
