New technology developed by bioengineers promises to make a workhorse lab tool cheaper, more portable and many times faster by accelerating the heating and cooling of genetic samples with the switch of a light.
Using a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid, researchers have developed a new capacitor dielectric material that provides an electrical energy storage capacity rivaling certain batteries, with both a high energy density and high power density.
Scientists have induced structures incorporated within individual cells to produce laser light. The wavelengths of light emitted by these intracellular microlasers differ based on factors such as the size, shape and composition of each microlaser, allowing precise labeling of individual cells.
The art of kirigami involves cutting paper into intricate designs, like snowflakes. Physicists are kirigami artists, too, but their paper is only an atom thick, and could become some of the smallest machines the world has ever known.
Researchers developed a model that explains how monomers could very rapidly make the jump to more complex polymers. And what their model points to could have intriguing implications for engineering artificial self-assembly at the nanoscale.
