Bridging Native and Intrinsic Structures of Microhydrated Biomolecules by Cold Ion Spectroscopy

Andrei Zviagin

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 ...

EPFL2023

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 ...

In-vitro and in-silico characterization of zein fiber incorporating cuminaldehyde

Niloufar Sharif

The zein solutions containing different concentrations of cuminaldehyde (5%, 10%, and 20%, w/w) were electrospun. The morphology and average diameter of fibers were evaluated by scanning electron microscopy and the optimized fiber (20% cuminaldehyde) was c ...

ELSEVIER2021

Particulate matter (PM) pollution causes adverse health effects and millions of deaths each year. PM or aerosol, is difficult to characterize because of its wide range of particle sizes, constituents (various organic and inorganic compounds), concentration ...

Black phosphorus quantum dots in inorganic perovskite thin films for efficient photovoltaic application

Michael Graetzel, Shaik Mohammed Zakeeruddin, Tong Zhang, Carole Graetzel, Mingkui Wang, Qingwei Li, Han Pan, Li Guan

Black phosphorus quantum dots (BPQDs) are proposed as effective seed-like sites to modulate the nucleation and growth of CsPbI2Br perovskite crystalline thin layers, allowing an enhanced crystallization and remarkable morphological improvement. We reveal t ...

High Resolution Fourier Transform Infrared Spectroscopy of the Quantum Magnet LiTmF4

In fundamental interactions research, dipolar magnets are particularly interesting to study since they provide a large spectrum of quantum phenomena [1-2]. Magnetic dipolar interaction are omnipresent in magnetic systems. However, in most of materials, var ...

Cryogenic 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 ...

Fourier transform spectroscopy in the vibrational fingerprint region with a birefringent interferometer

Christoph Peter Hauri

We introduce a birefringent interferometer for Fourier transform (FT) spectroscopy in the mid-infrared, covering the vibrational fingerprint region (5-10 µm, 1000-2000 cm-1), which is crucial for molecular identification. Our interferometer empl ...

Analysis of Aerosol in Zurich by Infrared Spectroscopy and Statistical Modelling

Satoshi Takahama, Giulia Ruggeri, 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. We use the Fourier transform infrared (FT-IR) absorbance spectra of atm ...

2017

We present results from a joint theoretical and experimental study of the low-energy Penning ionization of NH3, CH3F, and CHF3 by metastable Ne(P-3(2)) and He(S-3(1)) atoms. We combine the merged neutral beams experiment, covering a range of collision ener ...
