Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

Plasma Treatment on 1D Tungsten Disulfide Carbon Core–Shell Composites for Improved Performance in the Hydrogen Evolution Reaction

open access: yesSmall, EarlyView.
RF Ar plasma exposure selectively activates carbon‐coated WS2 nanotubes, substantially lowering the HER overpotential while preserving an ordered, conductive framework. A subsequent D2 plasma step produces interlayer expansion and greater structural disorder, reducing activity.

Advances in research on layered double hydroxides for biomedical applications

open access: yesSmart Molecules, EarlyView.
Layered double hydroxides (LDHs) are pH‐responsive nanomaterials with broad biomedical applications. This review summarizes LDH synthesis methods and compares their advantages. It highlights LDHs' progress in cancer therapy, including chemo‐photothermal, chemo‐immunotherapy, and photodynamic‐immunotherapy combinations and their potential in bone repair.

Engineering metal‐organic framework‐based smart porous nanoplatforms for targeted therapy and theranostic applications

open access: yesSmart Molecules, EarlyView.
MOFs offer high porosity and tunability for biomedical applications, especially in cancer therapy via ROS generation and targeted delivery. Though toxicity, stability, and scalability remain key clinical challenges. Drug loading in MOFs exceeds 60%–70% with controlled release behavior.
