Rare-earth materials are prime candidates for storing quantum information, because the undesirable interaction with their environment is extremely weak. Consequently however, this lack of interaction implies a very small response to light, making it hard to read and write data. Physicists have now observed a record-high Purcell effect, which enhances the material's interaction with light.
A new device could provide a non-invasive way to monitor the progress of an advanced cancer treatment. It can pick cancer cells out of a blood sample and let them go later, enabling further tests that can show whether the therapy is successfully ridding the patient of the most dangerous cancer cells.
An effective vaccine against the virus that causes genital herpes has evaded researchers for decades. But now, researchers have shown that zinc-oxide nanoparticles shaped like jacks can prevent the virus from entering cells, and help natural immunity to develop.
Researchers have developed a one-step, facile method to pattern graphene by using stencil mask and oxygen plasma reactive-ion etching, and subsequent polymer-free direct transfer to flexible substrates.
Many technologies rely upon nanomaterials that can absorb or release atoms quickly and repeatedly. New work provides a first look inside these phase-changing nanoparticles, showing how their shape and crystallinity affect their performance for battery applications.
