History. More than 50 years ago, MSI was introduced using secondary ion mass spectrometry (SIMS) to study semiconductor surfaces by Castaing and Slodzian. However, it was the pioneering work of Richard Caprioli and colleagues in the late 1990s, demonstrating how matrix-assisted laser desorption/ionization (MALDI) could be applied to visualize large biomolecules (as proteins and lipids) in ...
The Minnesota Supercomputing Institute was created in 1984 to provide high-performance computing resources to the University of Minnesota's research community. MSI currently has three HPC systems available for use. MSI is part of Research Computing in the Office of the Vice President for Research. Research Computing is an umbrella organization ...
Microprobe. Secondary-ion mass spectrometry ( SIMS) is a technique used to analyze the composition of solid surfaces and thin films by sputtering the surface of the specimen with a focused primary ion beam and collecting and analyzing ejected secondary ions. The mass/charge ratios of these secondary ions are measured with a mass spectrometer to ...

Surface science is the study of physical and chemical phenomena that occur at the interface of two phases, including solid – liquid interfaces, solid– gas interfaces, solid– vacuum interfaces, and liquid – gas interfaces. It includes the fields of surface chemistry and surface physics. [1] Some related practical applications are classed ...

An electromagnetic metasurface refers to a kind of artificial sheet material with sub-wavelength thickness. Metasurfaces can be either structured or unstructured with subwavelength-scaled patterns in the horizontal dimensions. [1] [2] [3] In electromagnetic theory, metasurfaces modulate the behaviors of electromagnetic waves through specific ...
Surface and Interface Analysis is a peer-reviewed scientific journal published by John Wiley & Sons since 1979. In thirteen issues per year, it publishes original research papers dealing with the development and application of techniques for the characterization of surfaces, interfaces and thin films. It is available both online and in print.
Boy's surface. An animation of Boy's surface. In geometry, Boy's surface is an immersion of the real projective plane in 3-dimensional space found by Werner Boy in 1901. He discovered it on assignment from David Hilbert to prove that the projective plane could not be immersed in 3-space. Boy's surface was first parametrized explicitly by ...
MALDI mass spectrometry imaging (MALDI-MSI) is the use of matrix-assisted laser desorption ionization as a mass spectrometry imaging [2] technique in which the sample, often a thin tissue section, is moved in two dimensions while the mass spectrum is recorded. [3] Advantages, like measuring the distribution of a large amount of analytes at one ...
