Preprocessing Procedure for Propagation Measurements on MEO Satellite Links

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper presents a software tool designed for preprocessing data from an experimental campaign aimed at characterizing the tropospheric propagation channel using Medium Earth Orbit (MEO) satellites. The collected data provide critical insights into the channel in scenarios involving continuous variations in azimuth and elevation, along with

Essential Role of Icosahedral Symmetry in the 3D Shape of AuAg Plasmonic Nanostars With High Aspect‐Ratio Legs

Small, EarlyView.
Electron nanodiffraction mapping was used to determine that the 3D leg configuration of branched plasmonic AuAg nanostars is associated with the icosahedral symmetry of the star core, providing a deeper understanding of their growth mechanism and thus paving the way to the development of optimized synthesis protocols targeting optical enhancement ...

Suppress Ru Over‐Oxidation Through Oxygen Vacancy Engineering – Showcase With Ni‐Modified RuO2 via Molten‐Salt Synthesis

Small, EarlyView.
Competitive OER catalyst for H2O splitting without using Ir is a luxury wish; Ru is an active element to do the job but often does not hold long. See how those scientists managed the task with Ni modified RuO2 suppressing Ru over‐oxidation through Oxygen Vacancy Engineering.

Thermal Operational Stability in Organic Thin Film Transistors: The Critical Role of Interface Composition and Deposition Conditions

Small Methods, EarlyView.
Operational thermal stability in organic thin‐film transistors is engineered through interfacial chemistry and deposition temperature. By pairing F10‐SiPc with different surface treatments and tuning substrate temperature during deposition, distinct transport regimes emerge, ranging from crystalline, trap‐prone behavior to reversible, thermally ...

Snapshot Multi-Wavelength Birefringence Imaging

Sensors
A snapshot multi-wavelength birefringence imaging measurement method was proposed in this study. The RGB-LEDs at wavelengths 463 nm, 533 nm, and 629 nm were illuminated with circularly polarized light after passing through a circular polarizer.

High‐Gloss SVBRDF Captur e Using Bounce Light

Computer Graphics Forum, EarlyView.
Abstract Reflectance capture aims at the visual reproduction of an object under varying illumination. Past works differ substantially in their experimental overhead, from single‐ or few‐image approaches, that employ significant (often learned) priors at the expense of biased reconstructions, to more accurate approaches that tend to be time‐consuming ...
