Elucidating the Three-Dimensional Structure of Piracetam through Rotational Spectroscopy. [PDF]

ChemistryOpen
Neutral 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 Engl
The 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]

ChemistryOpen
We 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 ...

Transferable Semiempirical Models for Judd-Ofelt Parameters and Multiphonon Relaxation in Eu³⁺ Complexes: Toward an Experiment-Free Luminescence Design. [PDF]

J Comput Chem
ABSTRACT The rational design of lanthanide‐based luminescent systems using purely theoretical approaches remains challenging due to the reliance of existing models on experimental data. Herein, we propose a theoretical protocol for the design of new Eu3+ based luminescent systems, starting from a previously synthesized and experimentally characterized ...

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 ...

Development of transient Monte Carlo in a fissile system with β-delayed emission from individual precursors using modified open source code OpenMC(TD)

Nuclear Engineering and Technology, 2023
In deterministic and Monte Carlo transport codes, β-delayed emission is included using a group structure where all of the precursors are grouped together in 6 groups or families, but given the increase in computational power, nowadays there is no reason ...
