Two-dimensional partial covariance mass spectrometry of large molecules based on fragment correlations
...
Covariance mapping [L. J. Frasinski, K. Codling, and P. A. Hatherly, Science 246, 1029 (1989)] is a well-established technique used for the study of mechanisms of laser-induced molecular ionization and decomposition. It measures statistical correlations between fluctuating signals of pairs of detected species (ions, fragments, electrons). A positiv...
In-situ temporal measurement of ultrashort laser pulses at full power during high-intensity laser-matter interactions
In laser-matter interaction experiments it is of paramount importance to be able tocharacterise the laser pulse on target (in-situ) and at full power. This allows pulse optimisationand meaningful comparison with theory, and can shed fundamental new light on pulse distortionsoccurring in or on the target. Here we introduce and demonstrate a new tech...
Improved spatial resolution of metabolites in tissue biopsies using high-resolution magic-angle-spinning slice localizat...
High-resolution magic-angle-spinning 1H NMR spectroscopy (HR-MAS NMR) is a well-established technique for assessing the biochemical composition of intact tissue samples. In this study, we utilized a method based on HR-MAS NMR spectroscopy with slice localization (SLS) to achieve spatial resolution of metabolites. The obtained 7 slice spectra from e...
Variations of paramagnetic defects and dopants in geo-MoS2 from diverse localities probed by ESR
Exfoliated flakes from molybdenite crystals often still serve as benchmark substrates for two-dimensional MoS2 fundamental and device-oriented research. In this article, results are reported of a multi-frequency electron paramagnetic resonance (EPR) study on a series of natural 2H MoS2 crystals taken from various (seven) geological sites with the i...
Modeling MMS observations at the Earth's magnetopause with hybrid simulations of Alfvénic turbulence
...
Magnetospheric Multiscale (MMS) observations of plasma turbulence generated by a Kelvin–Helmholtz (KH) event at the Earth's magnetopause are compared with a high-resolution two-dimensional (2D) hybrid direct numerical simulation of decaying plasma turbulence driven by large-scale balanced Alfvénic fluctuations. The simulation, set up with four obse...
X-Ray-Induced Growth Dynamics of Luminescent Silver Clusters in Zeolites
Herein, AlKα X-rays are used to drive the growth of luminescent silver clusters in zeolites. The growth of the silver species is tracked using Auger spectroscopy and fluorescence microscopy, by monitoring the evolution from their ions to luminescent clusters and then metallic, dark nanoparticles. It is shown that the growth rate in different zeolit...
SMolESY: An efficient and quantitative alternative to on-instrument macromolecular ¹H-NMR signal suppression
One-dimensional (1D) proton-nuclear magnetic resonance (1H-NMR) spectroscopy is an established technique for measuring small molecules in a wide variety of complex biological sample types. It is demonstrably reproducible, easily automatable and consequently ideal for routine and large-scale application. However, samples containing proteins, lipids,...
Analytic structure in fibers of H-infinity(B-c0)
Let H-infinity(B-c0) be the algebra of all bounded holomorphic functions on the open unit ball of c(0) and M(H-infinity(B-c0)) the spectrum of H-infinity(B-c0)). We prove that for any point z in the closed unit ball of l(infinity) there exists an analytic injection of the open ball B-l infinity into the fiber of z in M(H-infinity(B-c0)), which is a...
