To forge nanodiamonds, which have potential applications in medicine, optoelectronics and quantum computing, researchers expose organic explosive molecules to powerful detonations in a controlled environment. These explosive forces, however, make it difficult to study the nanodiamond formation process. To overcome this hurdle, researchers recently developed a procedure and a computer model that can simulate the highly variable conditions of explosions on phenomenally short time scales. They report their work in The Journal of Chemical Physics.
A novel technique that nudges single atoms to switch places within an atomically thin material could bring scientists another step closer to realizing theoretical physicist Richard Feynman’s vision of building tiny machines from the atom up.
ECS teamed up with Amazon to bring ECS members Amazon Catalyst at ECS. ECS members were able to interact with one of the world's largest companies and potentially be awarded a grant to tackle a number of different challenges.
Lab-on-a-chip devices harness electrical signals to measure glucose, tell apart blood type and detect viruses or cancer. But biological samples need hafnium oxide for protection from the electric fields.
Columbia Engineers have created the first flat lens capable of correctly focusing a large range of colors of any polarization to the same focal spot without the need for any additional elements. Only a micron thick, their revolutionary "flat" lens is much thinner than a sheet of paper and offers performance comparable to top-of-the-line compound lens systems. UPenn nanophotonics expert Nader Engheta, who was not involved with this study, notes: "This…is an exciting development in the field of flat optics.”
Scientists have developed a new catalyst for breaking carbon-fluorine bonds, one of the strongest chemical bonds known. The discovery is a breakthrough for efforts in environmental remediation and chemical synthesis.
