DESCRIPTION:Dr. Jake Koralek \nSLAC National Accelerator Laboratory\nStanf
 ord  \nThe physics and chemistry of liquid solutions play a central role 
 in science\, and our understanding of life on Earth. Unfortunately\, key t
 ools for interrogating aqueous systems\, such as infrared and soft X-ray s
 pectroscopy\, cannot readily be applied because of strong absorption in wa
 ter. In this talk I will present a microfluidic device that uses gas-dynam
 ic forces to generate free-flowing\, sub-micron\, liquid sheets which are 
 two orders of magnitude thinner than anything previously reported. These s
 heets can run in vacuum\, and are tunable in thickness from over 1 μm 
 down to less than 20 nm\, which corresponds to fewer than 100 water mo
 lecules thick. At this thickness\, aqueous sheets can readily transmit pho
 tons across the spectrum\, leading to potentially transformative applicati
 ons in infrared\, X-ray\, and electron spectroscopies.
