Self‐Sustained Oscillations in MoS2 Optomechanical Resonators for VHF Optical Radio

Advanced Photonics Research
We investigate self‐sustained oscillations on microdrum resonators manufactured with molybdenum disulfide, under continuous‐wave laser excitation. Control over these oscillations is demonstrated building a simple radio‐over‐laser link.

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

Small, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Vortex Domain Wall Imaging in a 3D Magnetic Nanotube Grown by Focused Electron Beam Induced Deposition

Small, EarlyView.
Synthesis of nanoscale high‐purity Co magnetic nanotubes using a single growth technique, focused electron beam induced deposition (FEBID). Utilizing electron holography and micromagnetic simulations, we demonstrate the nucleation and pinning of tilted vortex domain walls, providing crucial experimental evidence to advance 3D spintronics and ...

PROMOTION STRATEGY OF SCIENTIFIC VOCATION IN SECONDARY EDUCATION BY MEANS OF NANOSCIENCE AND NANOTECHNOLOGY DIFFUSION IN COSTA RICA

Momento, 2013
Current strategies in education leave nanoscience and nanotechnology aside from the process of learning the scientific method, thereby omitting a large portion of contemporary empirical knowledge. It is thus desirable to familiarize students in secondary

Effect of Zinc Oxide Nanoparticles From Infant Formula Milk Powder on Colon Cells In Vitro

Journal of Applied Toxicology, Volume 46, Issue 10, Page 3437-3445, October 2026.
ABSTRACT Zinc is an essential trace element that participates in numerous metabolic processes; however, excessive exposure may interfere with the absorption of other metals, such as copper. In recent years, nanotechnology has experienced rapid growth, and zinc oxide nanoparticles (ZnO NPs) have garnered significant attention due to their versatile ...

Extracellular Vesicles From Senescent Cancer Cells Are Necessary and Sufficient to Drive Paracrine Senescence

Aging Cell, Volume 25, Issue 10, October 2026.
Senescent cancer cells exhibit a secretory phenotype, known as SASP, capable of inducing paracrine senescence. However, the main factors within the SASP triggering this process are unknown. Here, we demonstrate that EVs within the SASP are necessary and sufficient to induce paracrine senescence.

Partial Atomic Charges, Dipole Moments and Electrostatic Potentials

Journal of Computational Chemistry, Volume 47, Issue 25, September 30, 2026.
Partial atomic charges are essential yet ill‐defined quantities in computational chemistry. We benchmark six population‐analysis methods, including the newly developed DPOD scheme, against dipole‐moment reproduction, electrostatic‐potential accuracy, and chemical transferability across 37 molecules.
