Not all calcite crystals perfect; synthesis methods can alter internal structure, affect chemical reactivity

When looking at calcite under a microscope, a scientist would immediately recognize the crystalline form of calcium carbonate by its rhombohedral appearance. That is, calcite is shaped like a distorted cube. One of Earth's ...

Ultrasound beam triggers 'nanodroplets' to deliver drugs at exactly the right spot

Conventional drug delivery is often like cracking a nut with a sledgehammer. Whether the drug is swallowed, injected, inhaled, or absorbed through the skin, it ultimately diffuses to most parts of the body, including those ...
