Elucidating the Three‐Dimensional Structure of Piracetam through Rotational Spectroscopy

ChemistryOpen, EarlyView.
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.

Arrowroot Starch/Carboxymethylcellulose‐ZnO NP Films: Thermal, Tensile, and Biodegradation Properties

Polymer Engineering &Science, EarlyView.
An overview of the manufacturing process and results of the Arrowroot starch/carboxymethylcellulose‐ZnO NP films. ABSTRACT Currently, more effective methods in the area of food preservation have been improved in recent years. In this context, active packaging can be highlighted, which interacts directly with food to increase its shelf life.

Towards Contactless Daylight Photoluminescence of PV Strings During Operation by Electrical Modulation

Progress in Photovoltaics: Research and Applications, EarlyView.
dPL usually requires two states (ON/OFF) to distinguish light from the panels from ambient light. dPLS(N): an electronic device forces a sub‐string of S‐N panels (a string of S panels) to work at two different points on the I‐V curve. In this example (S = 20), dPL20(6) shows a perfect square modulation of the current intensity throughout the ...
