First 3-D imaging of excited quantum dots

Quantum dots are rapidly taking center stage in emerging applications and research developments, from enhanced LCD TVs and thin-film solar cells, to high-speed data transfer and fluorescent labeling in biomedical applications.

New measurements to guide radiation therapy

When ionizing radiation passes through living tissue, it interacts with molecules present in the cells, stripping away electrons and producing charged species known as ions. Ionizing radiation used for cancer treatment includes ...

Life's building blocks observed in spacelike environment

Where do the molecules required for life originate? It may be that small organic molecules first appeared on earth and were later combined into larger molecules, such as proteins and carbohydrates. But a second possibility ...

The molecular structure of a forest aroma deconstructed

The fresh, unmistakable scent of a pine forest comes from a medley of chemicals produced by its trees. Researchers have now, for the first time, accurately determined the chemical structure of one of these compounds in its ...

Volatility surprises arise in removing excess hydrogen

Excess hydrogen can cause problems in a variety of industries. It can corrode semiconductors, electronics, and nuclear fuel sitting in storage. It also poses an explosion hazard. To remove this extra hydrogen, chemists can ...
