Novel Sulfur‐Rich Polymers from Inverse Vulcanization as Functional Building Blocks for Photonics

open access: yesMacromolecular Rapid Communications, EarlyView.
Isopropenyl aromatic comonomers, in particular novel 2,7‐diisopropenylfluorene and 2,8‐diisopropenyldibenzothiophene, synthesized by sustainable, facile, single‐step SMCCR from available brominated substrates are exploited in the Inverse Vulcanization process to obtain functional Sulfur‐rich macromolecular materials.

Behavior of a Novel Cyclic Olefin‐Based Hot‐Melt Adhesive in CFRP Adhesive Joints Compared to Conventional Epoxy‐Based Structural Adhesives

open access: yesPolymer Composites, EarlyView.
Rate‐dependent performance of composite adhesive joints using thermoset and thermoplastic adhesives, in terms of toughness and fatigue behaviour. ABSTRACT A recently developed hot‐melt adhesive (HMA) based on cyclic olefin chemistry, supplied as a transparent, non‐tacky thermoplastic film with a distinctive polymer microstructure, was evaluated in this

Unmanned Aerial Systems for Corrosion Detection: Multi‐Sensor Technologies, Challenges, and Opportunities for Next‐Generation Inspection

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.

Autonomous Navigation in Large‐Scale Underground Environments Based on a Purely Topological Understanding of Tunnel Networks

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This work presents a non‐geometrical navigation approach based on a purely topological understanding of underground environments. By conceptualizing subterranean scenarios as a set of tunnels that intersect with each other, and taking a navigation approach based on topological instructions, we simplify the navigation problem to the sequential ...

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Integrated LEO Constellation and In‐Cabin Distribution System for Continuous Aircraft 5G Connectivity

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency (>$$ > $$ 500 ms) and inadequate coverage at high ...
