Elucidating the Three-Dimensional Structure of Piracetam through Rotational Spectroscopy. [PDF]
ChemistryOpenNeutral molecules of the nootropic drug piracetam are generated by laser ablation and structurally characterized by microwave spectroscopy. Two conformers differing in the exo/endo configuration of the pyrrolidine ring are detected, with exo being the predominant form.

Sustainable and Simple Water-Induced Separation of Ionic Liquid Mixtures. [PDF]
Angew Chem Int Ed EnglThe cover image illustrates an innovative method for recovering ionic liquids (ILs) from their mixtures. This approach enables the recovery of over 99% of the IL by simply adding water–abundant, and safe solvent–under mild conditions, all while preserving the integrity of the ILs.

Rotational Spectroscopy as a Tool to Characterize Sweet Taste: The Study of Dulcin. [PDF]
ChemistryOpenWe provide experimental evidences that support the old theories of sweetness using dulcine as the archetypal molecule by means of Laser Ablation Chirped Pulse Fourier Transform Microwave Spectroscopy (LA‐CP‐FTMW) technique. Eluciding the structure of dulcin, we can decipher if it meets the structural requirements that a sweet molecule need to have ...

An arbuscular mycorrhiza from the 407-million-year-old Windyfield Chert identified through advanced fluorescence and Raman imaging. [PDF]
New PhytolSummary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

Magnetic Colloidal Currents Guided on Self‐Assembled Colloidal Tracks
Advanced Functional Materials, Volume 33, Issue 52, December 22, 2023., 2023 In this work, the ability of magnetic micro/nanoparticles to self‐assemble is exploited to construct pathways through which swarms of magnetic micro/nanoparticles are transported under low Reynolds number conditions. This disruptive strategy allows the study of superior transport mechanisms at the micro‐scale, as it is based on the ad hoc and flexible ...

Nanocrystalline Flash Annealed Nickel Oxide for Large Area Perovskite Solar Cells
Advanced Science, Volume 10, Issue 23, August 15, 2023., 2023 The industrialization of perovskite solar cells requires selecting adequate materials and processes to make them economically viable and environmentally sustainable. Nanocrystalline nickel oxide produced through flash infrared annealing reduces the time, cost, energy, and the amount of solvents required to produce hole transport layers in perovskite ...

Materials and Corrosion, Volume 74, Issue 6, Page 818-830, June 2023., 2023 Hollow wire corrosion of stainless steel ropes from mooring installations applied in seawater is introduced. Martensite distribution in the austenite and crystallographic texture resulting from the production technology of the cold‐drawn wires are identified as decisive for this kind of corrosion.

Chemistry – A European Journal, Volume 29, Issue 24, April 25, 2023., 2023 Fluorinated α‐amino acids have been attracting increasing attention, but their structure in the gas‐phase has not been investigated yet. Fluorination has a negligible impact on steric properties, but has a dramatic effect on the electronic properties. 4‐fluoro‐threonine has been efficiently synthesized in large amount and its conformational landscape ...

A Mini Atlas of H-Band Spectra of Southern Symbiotic Stars
Galaxies, 2023 Symbiotic stars are interacting binary systems composed of an evolved star (generally a late-type red giant) and a degenerate or dwarf companion in orbit close enough for mass transfer to occur. Understanding the status of the late-type star is important
