The shape of sonoluminescence
Sonoluminescence occurs because sound waves cause a bubble to expand and then collapse in a liquid. The bubble first expands to almost 10 times its original dimensions, and then collapses at supersoni...
Superfluidity seen on microscopic scales
Bulk superfluid helium has many unusual properties – it can flow up walls and through narrow pores without resistance. Helium-4 and helium-3 become superfluid below 2.12 and 0.003 Kelvin respect...
Organic laser breakthrough
Organic lasers are attractive for optical applications because they are inexpensive to manufacture, can be grown as thin films and have good temperature stability. Results from the Princeton team sugg...
