New X-ray technique may lead to better, cleaner fuel injectors for automobiles (2/20/2008)

Standard microscopy and visible light imaging techniques cannot peer into the dark and murky centers of dense-liquid jets, which has hindered scientists in their quest for a full understanding of liquid breakup in devices such as automobile fuel injectors. ...> Full Article

Heat Pumps 'Go With The Flow' To Boost Output (1/30/2008)

Air-source heat pumps typically deliver 1 1/2 to three times more heating energy to a home than the electric energy they consume. This is possible because heat pumps move heat rather than convert it from a fuel (as combustion heating systems do). National Institute for Standards and Technology (NIST) researchers are working to improve the performance of these energy superstars even further by providing engineers with computer-based tools for optimizing heat exchanger designs. ...> Full Article

'Electrospray' Droplet Research Yields Surprising, Practical Results (1/13/2008)
