Cu-BTC proves redox capable, opens new doors for catalysis and gas storage
Redox ready
Released: April 24, 2012
The metal organic framework, Cu-BTC, is redox capable, and its ratio of Cu2+ to Cu+ can be controlled via atmosphere and temperature conditions. This new finding by an EMSL research team will open doors for gas storage and catalysis applications.
Proteogenomic strategies help refine annotations of three Yersinia strains
Annotating Plague
Released: April 11, 2012
Strains of bacteria from the genus Yersinia are pathogenic with a wide virulence range. To better understand and potentially design ways to mitigate the effects of Yersinia on human health, EMSL users leveraged proteome and transcriptome data to refine the genome maps of three Yersinia strains.
EMSL's novel spectroscopy device pairs visual clarity with sub-monolayer sensitivity
Angling for Answers
Released: March 27, 2012
EMSL staff and users from the Chinese Academy of Sciences analyzed polarization-dependent SFG vibrational spectra of the monovalent -CN groups buried in the C18CN (organic cyanide) insoluble Langmuir monolayer at the air-water interface.
Transmission electron microscopy transforms how we see lithium-ion batteries
Not Fade Away
Released: March 27, 2012
Generating longer-life lithium-ion (Li-ion) batteries could be part of the remedy for overdependence on fossil fuels, affecting everything from vehicles to manufacturing. Using EMSL's in situ TEM capabilities, scientists are edging closer to pinpointing the atomic-level changes that lead to anode failure in Li-ion batteries.
Novel method yields highly reactive, highly hydroxylated TiO2 surface
Water, Sun, Energy
Released: March 21, 2012
EMSL users created a novel method to produce a highly reactive, OH-rich TiO2 surface and characterized it at the atomic level. Their work, featured on the cover of the March 7, 2012 issue of PCCP, puts us one step closer to using H2O and TiO2 to make energy-rich hydrogen.
Dynamic proteome analysis of Cyanothece 51142
Shedding Light on Photosynthesis
Released: March 15, 2012
EMSL users measured dynamic changes within Cyanothece when it performed photosynthesis, using a metabolic labeling approach that goes a step beyond static, traditional proteomics studies and provides greater insight into how proteins are expressed as a function of time.
New data may explain why models underestimate organic aerosols
Sticking Around
Released: March 01, 2012
Airborne particles impact human health, cause haze, and influence climate. New findings reported by an EMSL user team in PNAS may explain why the abundance of secondary organic aerosols, which make up more than half of the mass of airborne particles, has been significantly underestimated by currently accepted air quality and climate models.
Unparalleled time, spectral resolution benefit surface science studies at EMSL
Attention to Detail
Released: February 29, 2012
Femtosecond time resolution and sub-wavenumber spectral resolution are now available in EMSL's unique, in-house designed and custom-built high-resolution broadband sum-frequency generation vibrational spectroscopy capability. Ideal for characterizing surfaces and interfaces, details about HR-BB-SFG-VS are reported in the December issue of JCP.
