Structural and Rheological Properties of Chitosan‐Biochar Composites Prepared With Waste Biomass‐Derived Biochar

Polymer Engineering &Science, EarlyView.
Chitosan dispersions containing biochar derived from vine pruning residue showed increasing shear stress and improved thermal stability with loading. Flow behavior was described by the Bingham plastic model in all cases. These results support the valorization of agricultural waste in functional biopolymer formulations.

Design and optoelectronic profiling of a semicrystalline thiophene–phenylene copolymer for advanced organic electronics

Polymer International, EarlyView.
A new semicrystalline copolymer, PTBT‐3OBu, was synthesized. Intramolecular S···O conformational locks induce high backbone planarity, promoting strong interchain coupling and molecular ordering in thin films, seen in an optical red shift. This synergy between planarity and semicrystalline morphology is promising for photovoltaic and electrochromic ...

Characteristics of upper‐level updrafts and downdrafts in the anvils of tropical deep convective clouds

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study investigates the thermodynamic and microphysical characteristics of updrafts and downdrafts of tropical deep convective anvil clouds using in situ measurements. We found that parts of the downdrafts are in ice supersaturation in these clouds.

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

Journal 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

A Comparison of Mobile Laser Scanning Data Acquisition Methods in Closed Forest, Open Woodland and Sub‐Alpine Woodland Ecosystems

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that the mobile laser scanning (MLS) sampling density required to reliably characterise vegetation structure increases with a site's structural complexity. Applying a five‐level acquisition framework across open woodland, closed forest and sub‐alpine woodland ecosystems, we found that longer scanning paths increased the ...
