In a new study, chemists have explored protactinium's multiple resemblances to more completely understand the relationship between the transition metals and the complex chemistry of the early actinide elements.
Researchers have produced a 'human scale' demonstration of a new phase of matter called quadrupole topological insulators that was recently predicted using theoretical physics. These are the first experimental findings to validate this theory.
Scientists have developed a new method that utilizes microscopic splinter-like structures for the targeted delivery of biomolecules such as genes straight to patient cells. These magnetically guided nanostructures could enable gene therapies that are safer, faster and more cost-effective.
In a step toward accelerating the production of new gene therapies, scientists report that they have developed remote-controlled, needle-like nanospears capable of piercing membrane walls and delivering DNA into selected cells.
Their unprecedented internal surface areas and easy chemical tunability allow MOFs to 'pull' water vapor and other gases from air. These same features make them promising materials also for selectively removing heavy metals from water.
