Background: Magnolia alejandrae is a tree endemic to Tamaulipas, Mexico, distributed in the forests of the Sierra Madre Oriental. Objective: Our objective was to analyze the secondary metabolite profile of different parts of M. alejandrae and evaluate their antiproliferative activity in vitro. Methods: Different extracts of leaf, bark, and fruit were obtained using conventional and unconventional extraction methods with solvents of different polarity. The extracts were analyzed by Ultra-Performance Liquid Chromatography-Mass Spectra (UPLC-MS), and their antiproliferative activity against cancer cell lines was determined. Results: The primary yields of the extracts obtained from M. alejandrae ranged from 8.32% to 36.19%. Three hundred and twelve secondary metabolites previously reported from the Magnolia genus were detected. The most frequent were magnone A, pinoresinol, and yangambin. Honokiol and magnolol were not detected. Two of the extracts (FSW and BSW) had antiproliferative activity (IC50 < 140 µg/mL) against HeLa, MCF-7, A549, U373, and PC3 cancer cell lines. The higher activity was against the A549 cell line. Conclusions: M. alejandre extracts showed secondary metabolites previously reported and unreported in other species. Interestingly, some extracts had antiproliferative activity against cancer cell lines. Therefore, M. alejandrae is a source of molecules that could be explored to develop new drugs. Full article

Over the last few years, research activities have seen two-dimensional (2D) materials become protagonists in the field of nanotechnology. In particular, 2D materials characterized by ferroelectric properties are extremely interesting, as they are better suited for the development of miniaturized and high-performing devices. Here, we summarize the recent advances in this field, reviewing the realization of devices based on 2D ferroelectric materials, like FeFET, FTJ, and optoelectronics. The devices are realized with a wide range of material systems, from oxide materials at low dimensions to 2D materials exhibiting van der Waals interactions. We conclude by presenting how these materials could be useful in the field of devices based on magnons or surface acoustic waves. Full article

Magnonic activity, a chiral effect in magnetization dynamics, was recently reported in ferromagnetic nanotubes. Being a perfect analogy to the optical activity, it refers to the continuous rotation of a standing-waves pattern formed in the circumferential direction during the wave propagation along the tube. This effect only occurs when the tube is longitudinally magnetized. Here we report that a similar phenomenon can also take place in circularly magnetized nanotubes with the presence of Dzyalonshinskii-Moriya interaction (DMI). While in the former case, the chiral-symmetry breaking is caused by the curvilinear shape of the tube, it is attributed to the intrinsic asymmetry of the DMI in the latter one. We present the results obtained in both numerical simulations and semi-analytical calculations, which are in great agreement. This work provides new aspects for the manipulation of spin waves, which may bear potential applications in the development of novel spintronic devices. Full article
