Some substances, when they undergo a process called rapid-freezing or supercooling, remain in liquid form - even at below-freezing temperatures. A new study is the first to break down the rules governing the complex process of crystallization through rapid-cooling. Its findings may revolutionize the delivery of drugs in the human body, providing a way to 'freeze' the drugs at an optimal time and location in the body.
Researchers developed an inkjet printing technology to produce kesterite thin film absorbers (CZTSSe). Based on the inkjet-printed absorbers, solar cells with total area conversion efficiency of up to 6.4 % have been achieved.
A revolution is coming in flexible electronic technologies as cheaper, more flexible, organic transistors come on the scene to replace expensive, rigid, silicone-based semiconductors, but not enough is known about how bending in these new thin-film electronic devices will affect their performance.
Researchers have discovered topologically protected one-dimensional electron conducting channels at the domain walls of bilayer graphene. These conducting channels are 'valley polarized', which means they can serve as filters for electron valley polarization in future devices such as quantum computers.
