30-year Trends that Encourage Bay of Bengal Cyclones
The intensity of post-monsoon tropical cyclones in the Bay of Bengal has increased over the 30-year period from 1981-2010, found scientists at Pacific Northwest National Laboratory and the Atlanta Oceanographic and Meteorological Laboratory. The culprit? Trending increases in certain environmental conditions that brew up these storms: increased sea surface and upper ocean temperatures and atmospheric instability.

Window into Liquid Analysis Earns PNNL an R&D 100 Award
SALVI enables real-time imaging of liquid samples by more than one analytical instrument
Many studies rely on knowing precisely how solids and liquids interact on a molecular level, but liquids evaporate in the vacuum of certain powerful scientific instruments. PNNL developed SALVI, or the System for Analysis at the Liquid Vacuum Interface, that for the first time allows these instruments to image liquid samples in real time. R&D Magazine honored SALVI’s research team with a 2014 R&D 100 award. The magazine selects the 100 most innovative scientific and technological breakthroughs of the year.
Cherry Picking Molecules Based on Their Pi Electrons
New material has second-to-none selectivity for ethylene, a high-demand industrial chemical
Specialized windshield glass, everyday plastic water bottles, and countless other products are based on ethylene. Manufacturing it requires an energy-intense separation process that plucks the desired chemical from nearly identical ethane. To ease the energy required, an international team including researchers at Pacific Northwest National Laboratory designed a material with a porous framework that greatly prefers ethylene. The material contains silver that binds with the electrons around ethylene's double-bonded carbon atoms. These electrons are known as π electrons or the π cloud.
