J Phys Chem B
May 2019
Institute of Thermal-, Environmental- and Resources' Process Engineering (ITUN) , Technische Universität Bergakademie Freiberg (TUBAF), Leipziger Strasse 28 , 09599 Freiberg , Germany.
Article Synopsis
- The study introduces a method for analyzing hydrogen bond networks (HBNs) in mixtures of water and various organic solvents using optical techniques.
- It employs experimental and computed Raman spectra to examine how hydrogen bonds form between different molecules in these mixtures.
- Results indicate that the composition and temperature significantly affect the development of HBNs in the mixtures, highlighting the interactions between water and the organic solvents.
Questioning Seasonality of Neuronal Plasticity in the Adult Avian Brain.
Sci Rep
July 2018
Department of Natural and Life Sciences, The Open University of Israel, Ra'anana, 43107, Israel.
To date, studies that reported seasonal patterns of adult neurogenesis and neuronal recruitment have correlated them to seasonal behaviors as the cause or as a consequence of neuronal changes. The aim of our study was to test this correlation, and to investigate whether there is a seasonal pattern of new neuronal recruitment that is not correlated to behavior. To do this, we used adult female zebra finches (songbirds that are not seasonal breeders), kept them under constant social, behavioral, and spatial environments, and compared neuronal recruitment in their brains during two seasons, under natural and laboratory conditions.

Article Synopsis
- Microemulsions are commonly used in advanced material and chemical processing but often require large amounts of surfactants, posing economic and ecological challenges.
- Researchers have explored surfactant-free microemulsion-like systems utilizing carbon dioxide in a water/organic-solvent/CO mixture, which creates unique "water-rich" nanodomains within a "water-depleted" matrix.
- These systems feature pressure-responsive nanostructuration, allowing for rapid and reversible mixing and demixing of contents, making them promising for molecular material processing and chemical engineering applications due to their contaminant-free nature and ability to dissolve various molecules.
In Situ Raman Analysis of CO₂-Assisted Drying of Fruit-Slices.
Foods
May 2017
Department of Industrial Engineering, University of Padova, via Marzolo 9, 35131 Padova, Italy.
Article Synopsis
- This study looks at using in situ Raman spectroscopy to monitor how fruits, specifically mango and persimmon, are dried using supercritical carbon dioxide (SC-CO₂).
- The experiments were done at high pressure (10 MPa) and temperature (313 K), focusing on changes in water content and fruit structure during drying.
- The findings show that using a 532 nm excitation wavelength provides better quality spectra compared to 785 nm, and that CO₂ absorption helps improve water extraction from the fruit.
GSK3ß-dependent dysregulation of neurodevelopment in SPG11-patient induced pluripotent stem cell model.
Ann Neurol

IZKF Junior Research Group III and BMBF Research Group Neuroscience, Friedrich-Alexander-Universitaet Erlangen-Nuernberg (FAU), Erlangen, Germany.
Objective: Mutations in the spastic paraplegia gene 11 (SPG11), encoding spatacsin, cause the most frequent form of autosomal-recessive complex hereditary spastic paraplegia (HSP) and juvenile-onset amyotrophic lateral sclerosis (ALS5). When SPG11 is mutated, patients frequently present with spastic paraparesis, a thin corpus callosum, and cognitive impairment. We previously delineated a neurodegenerative phenotype in neurons of these patients.

†Lehrstuhl für Technische Thermodynamik (LTT), Friedrich-Alexander-Universitaet Erlangen-Nuernberg (FAU), Am Weichselgarten 8, 91058 Erlangen, Germany.
Article Synopsis
- A new method using phase-selective Raman spectroscopy enables fast and noninvasive measurement of vapor-liquid equilibria (VLE) in multiphase flows within microcapillaries.
- This technique was tested on binary and ternary mixtures (acetone, water, carbon dioxide, and nitrogen) at high pressures (up to 10 MPa) and temperatures (up to 333 K).
- The findings were validated with existing data and expanded the high-pressure VLE database by exploring conditions not previously documented.
