Iron(III) ion reinforced P(NiPAAm‐co‐AA) beads as tunable smart organogels

open access: yesPolymer International, EarlyView.
Macroporous beads of PNiPAAm‐co‐AA copolymers were further crosslinked by iron(III) ions. The resulting beads are mechanically robust and reversibly responsive to a change of solvent from ethanol to ethyl acetate with half‐lives in the range of minutes.

Identifying Suitable Front Contacts for High‐Efficiency Cd(Se,Te) Solar Cells on Space‐Qualified Cover Glass

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Front contact selection governs interfacial stability in CdTe‐based (Cd(Se,Te)) solar cells on ultra‐thin space‐qualified cover glass. Optimized TCO/emitter combinations suppress interdiffusion and deliver up to 16.2% AM0 efficiency with high specific power, demonstrating strong potential for lightweight space photovoltaics.

Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.

Electron Transfer Dissociation and Synchrotron UV Photodissociation of Trapped Sodiated Ions Produced From Polyacrylates by Electrospray Ionization

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the purpose of this work was to evaluate the contribution of alternative activation techniques to the collisional activation, based on ion–ion and ion–photon interactions.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

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 ...
