Magnetic Nanoparticles with On-Site Azide and Alkyne Functionalized Polymer Coating in a Single Step through a Solvothermal Process.

: Magnetic FeO nanoparticles (MNPs) are becoming more important every day. We prepared MNPs in a simple one-step reaction by following the solvothermal method, assisted by azide and alkyne functionalized polyethylene glycol (PEG400) polymers, as well as by PEG6000 and the polyol β-cyclodextrin (βCD), which played a crucial role as electrostatic stabilizers, providing polymeric/polyol coatings around the magnetic cores. : The composition, morphology, and magnetic properties of the nanospheres were analyzed using Transmission Electron and Atomic Force Microscopies (TEM, AFM), Nuclear Magnetic Resonance (NMR), X-ray Diffraction Diffractometry (XRD), Fourier-Transform Infrared Spectroscopy (FT-IR), Matrix-Assisted Laser Desorption/Ionization (MALDI) and Vibrating Sample Magnetometry (VSM).

Synthesis of (-)-Cannabidiol (CBD), (-)-Δ- and (-)-Δ-Tetrahydrocannabinols, Encapsulation of CBD with Nanoparticles for Controlled Delivery and Biological Evaluation.

Cannabidiol (CBD) is garnering increasing interest due to its significant biological activity. This natural compound is one of the major cannabinoids in Cannabis sativa L. In this work, we describe the encapsulation of CBD in solid and hollow pH-sensitive poly(4-vinylpyridine) (solid@p4VP and hollow@p4VP) nanoparticles, and temperature-sensitive poly(N-isopropylacrylamide) (solid@pNIPAM and hollow@pNIPAM) nanoparticles for transport and release CBD in a controlled manner.

Exploring dynamic solvation kinetics at electrocatalyst surfaces.

The interface between electrocatalyst and electrolyte is highly dynamic. Even in absence of major structural changes, the intermediate coverage and interfacial solvent are bias and time dependent. This is not accounted for in current kinetic models.

Diverse Methods with Stereoselective Induction in the Asymmetric Biginelli Reaction.

The relevance of the asymmetric Biginelli reaction (ABR) has been increased in this century, due to the pharmacological application of its products. This review focuses predominantly on articles published in the period from 2015 to 2024 on asymmetric synthetic advances in the formation of dihydropyrimidinones (DHPMs), dihydropyrimidinethiones (DHPMTs), and related compounds. The relevant bibliography on general processes in the Biginelli reaction and some methods of separation of isomers have also been referenced.
