Mass Spectrometry Uses in Alternative Energy

Mass spectrometry determines the molecular weight of ionized molecules, from small metabolites to large biological compounds like proteins.  New refinements to this technique also allow measurement of the three-dimensional structure of the ions using a method called ion mobility spectrometry.  We have new instrumentation that combines laser desorption ionization and/or electrospray ionization with ion mobility and time-of-flight mass spectrometry to provide even more thorough measurements of the actual structures of the ions.  This instrumentation is being used to monitor met

Heterogeneous catalysts for renewable energy

SULI 1: Precious metals and metal alloys are important heterogeneous catalysts for renewable energy and materials. However, both of them have their limitations. Precious metals have low natural abundance and are expensive. Metal alloys have unstable surfaces due to surface segregation under reaction conditions, which renders the identification of active sites and the understanding of reaction mechanisms difficult. My research group will address these limitations by developing new intermetallic NP catalysts.

Quantum control of magnetism

We seek motivated undergraduates in our lab to address an outstanding and cross-cutting challenge of condensed matter/chemical/biological physics: how to achieve quantum control of magnetism and reveal highly non-equilibrium, “thermodynamically hidden†orders during femtosecond timescales? One example is a new paradigm discovered by our group called quantum femtosecond magnetism—fs magnetic and electronic phase transitions driven by quantum spin flucations and laser-excited inter-atomic coherences (T. Li, et al., Nature, 496, 69, 2013).

Nanostructured materials

"We develop high surface nanostructured materials, functionalized with multiple organic and inorganic groups to make smart multitasking nanoparticles. We employ these nanomaterials to various fields such as catalysis, CO2 capture and conversion, environmental remediation as well as biomedical research and biotechnology.

Ames Laboratory leads with new cutting edge NMR technology

The U.S. Department of Energy’s (DOE) Ames Laboratory has announced that it will acquire a Dynamic Nuclear Polarization-NMR spectrometer, a giant step forward in the laboratory’s world-class solid state NMR capabilities. The Ames Laboratory’s instrument will be the first of its kind to be focused on materials and materials chemistry in the United States.

Keep your cyber guard up

Image Ames Laboratory employees should always be on guard against possible cyber-attacks and practice good computer security measures but on Aug. 12-15 a little extra vigilance would be advisable. A team of DOE cyber security experts will be on site checking network security as part of the Safeguards and Security review.
