Researchers have shown record external quantum efficiencies for diodes based on organic red/NIR oligomers free from heavy/toxic metals and combining electron-withdrawing (A) moieties together with electron-donating (D) ones, in a previously poorly studied A-D-A motif.
Materials scientists have written the recipe on how to use an oddball enzyme to build new biomaterials out of DNA. The work provides instructions for researchers the world over to build self-assembling molecules for applications ranging from drug delivery to nanowires.
For the first time, researchers have demonstrated a way to deliver a drug to a tumor by attaching it to a blood cell. The innovation could let doctors target tumors with anticancer drugs that might otherwise damage healthy tissues.
In a recent experiment, a microwave resonator, a circuit that supports electric signals oscillating at a resonance frequency, is coupled to the vibrations of a metallic micro-drum. By actively cooling the mechanical motion close to the lowest energy allowed by quantum mechanics, the micro-drum can be turned into a quantum reservoir - an environment that can shape the states of the microwaves.
