Spectroscopic detection of multiple populations in the similar to 2 Gyr old cluster Hodge 6 in the LMC

We report the spectroscopic discovery of abundance spreads (i.e. multiple populations) in the similar to 2 Gyr old cluster in the LMC, Hodge 6. We use low-resolution VLT FORS2 spectra of 15 member stars in the cluster to measure their CN and CH band streng ...

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 ...

Nanocrystalline ZnO Obtained by the Thermal Decomposition of [Zn(H2O)(O2C5H7)(2)] in 1-Butanol: Synthesis and Testing as a Sensing Material

Thomas Maeder

The influence of conditions of heat treatment of a solution [Zn(H2O)(O2C5H7)(2)] in 1-butanol (temperature 125-185 degrees C, treatment times 2, 4, and 6 h) on dispersion and microstructure of the formed nanocrystalline and poorly aggregated zinc oxide, pr ...

Insertion of germanium atoms in high- nuclearity rhodium carbonyl compounds: synthesis, characterization and preliminary biological activity of the heterometallic [ Rh13Ge( CO) 25] 3-, [ Rh14Ge2( CO) 30] 2-and [ Rh12Ge( CO) 27] 4-clusters+

Paul Joseph Dyson, Silvia Ruggieri

The reaction of the Rh-7(CO)(16) cluster anion with Ge2+ salts, in different stoichiometric ratios and under different atmospheres, leads to the formation of new heterometallic Rh-Ge clusters, representing the first known examples of Rh carbonyl comp ...

Cryogenic infrared spectroscopy as a probe of structure and dynamics of biomolecules

Valeriu Scutelnic

The pivotal theory of molecular biology states that the structure of biomolecules is directly related to their function in living systems. In this way, the structural investigation of biological molecules allows understanding and intervening in the fundame ...

High-Contrast Infrared Absorption Spectroscopy via Mass-Produced Coaxial Zero-Mode Resonators with Sub-10 nm Gaps

Hatice Altug, Aurélian Michel John-Herpin, Sunghwan Kim

We present a wafer-scale array of resonant coaxial nanoapertures as a practical platform for surface-enhanced infrared absorption spectroscopy (SEIRA). Coaxial nanoapertures with sub-10 nm gaps are fabricated via photolithography, atomic layer deposition o ...

Toward Bloch Surface Wave-Assisted Spectroscopy in the Mid-Infrared Region

Hans Peter Herzig, Grégoire Maxime Smolik, Nicolas Maxime André Descharmes

We present the first observation of Bloch surface waves in the mid-infrared spectral range. Bloch surface waves are electromagnetic states that can propagate at the interface between a continuous dielectric medium and a periodic stack of materials. We desi ...

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 ...

Microhydration of Dibenzo-18-Crown-6 Complexes with K+, Rb+, and Cs+ Investigated by Cold UV and IR Spectroscopy in the Gas Phase

Thomas Rizzo, Yoshiya Inokuchi

In this Article, we examine the hydration structure of dibenzo-18-crown-6 (DB18C6) complexes with K+, Rb+, and Cs+ ion in the gas phase. We measure well-resolved UV photodissociation (UVPD) spectra of K+·DB18C6·(H2O)n, Rb+·DB18C6·(H2O)n, and Cs+·DB18C6·(H2 ...

The Contribution of Mechanical Spectroscopy to Understanding Grain Boundary Sliding

Daniele Mari

This review paper shows that grain boundary sliding (GBS) is a general phenomenon occurring in all classes of inorganic materials: ceramics, metals and composite materials. The occurrence of relaxations attributed to GBS is also quite general and therefore ...
