Embracing superficial imperfections

Chemists normally work rigorously to exclude impurities from their reactions. This is especially true for scanning tunneling microscopy (STM) experiments that can produce atomic-scale images of surfaces. Using STM to investigate ...

'Nanocrystal doping' enhances semiconductor nanocrystals

Researchers at the Hebrew University of Jerusalem have achieved a breakthrough in the field of nanoscience by successfully altering nanocrystal properties with impurity atoms -- a process called doping – thereby opening ...

Bacteria munch up alumina impurities

Previously unknown species of naturally-occurring bacteria have the potential to save the alumina and aluminium industries millions of dollars while helping to reduce their impact on the environment, microbiologist Naomi ...

Researchers put a new spin on atomic musical chairs

Researchers from the National Institute of Standards and Technology and the Naval Research Laboratory have developed a new way to introduce magnetic impurities in a semiconductor crystal by prodding it with a scanning tunneling ...

Fluorescent nematodes can help monitor indoor air impurities

Good quality indoor air is crucial to our well-being, while impurities in the air can compromise our working capacity and health. Researchers at the University of Turku in Finland have developed a new method for measuring ...
