Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications
Packaging Technology and Science, EarlyView.Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review
SmartBot, EarlyView.Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Small, EarlyView.Spatially resolved series resistance in monolithic perovskite/silicon tandem solar cells is extracted using voltage‐dependent photoluminescence imaging. The method is robust against current mismatch, shunt resistance, and luminescence coupling. Even in a high‐performance 29% efficiency device, resistive losses contribute up to 1.9% absolute efficiency ...

Periodontology 2000, EarlyView., 2023 Abstract Periodontitis is a long‐term condition affecting up to half of the population globally and causing significant impacts on life quality. Successful management depends on taking life‐long ownership of the condition by those affected. There is a wealth of research to inform on management options. However, most of the research has been designed by

Re-recognized universality of Kozai oscillation on three-body dynamics
Proceedings of the Japan Academy. Series B, Physical and Biological SciencesIn 1962, Yoshihide Kozai reported his findings on the secular dynamics of asteroids moving in orbits with high inclination and eccentricity. In contrast to the classic understanding of the stability of planetary motion in the solar system, Kozai showed ...
