Bridging Native and Intrinsic Structures of Microhydrated Biomolecules by Cold Ion Spectroscopy
Solving native structures of such large molecules, like biomolecules, is often challenging, particularly due to the potentially infinite number of non-covalent interactions with water. In this thesis, we report the use of cold ion gas-phase action spectros ...
EPFL2023Chemical characterization of organic aerosols with a focus on biomass burning and mid-infrared spectroscopy
Aerosols play a significant role in the atmosphere through affecting the radiative budget, cloud condensation nuclei activity, and visibility. They also cause adverse health effects leading to premature deaths. A major fraction of aerosols is organic matte ...
EPFL2022Broadband Optical Spectrum Downconversion to RF Using Integrated Dual-Comb Source
Combining all the benefits of Fourier transform infrared (FTIR) spectroscopy in a chip scale spectroscopic sensor looks promising for mobile and wearable platform development. Dual-comb spectroscopy enables downconversion of optical absorption spectra into ...
IEEE2021Promising anti-cancer potency of 4,5,6,7-tetrahydrobenzo[d]thiazole-based Schiff-bases
Kurt Schenk, Farzaneh Fadaei Tirani
Four new Schiff-bases have been synthesized from the 1:2 M condensation of 4,5,6,7-tetrahydrobenzothiazole-2,6-diamine with 2-hydroxybenzaldehyde (SL3), 5-Bromo-2-hydroxybenzaldehyde (SL2), 2-hydroxy-3-methoxybenzaldehyde (SL3) and 2-hydroxy-1-naphthaldehy ...
ELSEVIER2020Quantitative intrinsic auto-cathodoluminescence can resolve spectral signatures of tissue-isolated collagen extracellular matrix
Peter Frey, Jeffrey Alan Hubbell, Hans Mattias Larsson, Elif Vardar, Ganesh Vythilingam, Marcin Stefan Zielinski
By analyzing isolated collagen gel samples, we demonstrated in situ detection of spectrally deconvoluted auto-cathodoluminescence signatures of specific molecular content with precise spatial localization over a maximum field of view of 300 mu m. Correlati ...
2019Cryogenic IR spectroscopy combined with ion mobility spectrometry for the analysis of human milk oligosaccharides
Thomas Rizzo, Michael Zachary Kamrath, Chiara Masellis, Neelam Khanal
We report here our combination of cryogenic, messenger-tagging, infrared (IR) spectroscopy with ion mobility spectrometry (IMS) and mass spectrometry (MS) as a way to identify and analyze a set of human milk oligosaccharides (HMOs) ranging from trisacchari ...
2018Regional Similarities and NOx-Related Increases in Biogenic Secondary Organic Aerosol in Summertime Southeastern United States
Athanasios Nenes, Satoshi Takahama, Giulia Ruggeri, Junqiu Liu
During the 2013 Southern Oxidant and Aerosol Study, Fourier transform infrared spectroscopy (FTIR) and aerosol mass spectrometer (AMS) measurements of submicron mass were collected at Look Rock (LRK), Tennessee, and Centreville (CTR), Alabama. Carbon monox ...
Blackwell Publishing Ltd2018Multi Seasonal Functional Group Analysis by FT-IR Spectroscopy of Atmospheric Aerosol in Zurich
Satoshi Takahama, Matteo Reggente
Atmospheric particulate matter (PM) has been associated with increased morbidity and mortality, reduced visibility, and is one of the least understood components of the climate system. Organic matter (OM) constitutes a substantial fraction (up to 80%) of P ...
2017Experimental and theoretical studies on electropolymerization of polar amino acids on platinum electrode
The anodic oxidation of polar amino acids (L-serine, L-threonine, L-asparagine, and L-glutamine) in aqueous electrolyte on smooth platinum electrode was carried out by cyclic voltammetry coupled to electrochemical quartz crystal microbalance (EQCM). pH (zw ...
Elsevier2017Multilaser Conformer-Selective Spectroscopy of Cold Biomolecular Ions in the Gas Phase
Proteins and even small peptides play crucial role in almost any biological. Biological activity and functionality of these building blocks of life are determined not only by their primary structure, but also by their 3D orientation â secondary, tertiary ...
