Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

Advanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Influence of Foaming Agent Type on The Behavior of Foamed Concrete

Engineering and Technology Journal, 2021
In this work the desired aim is to study the effect of two various sorts of a foaming agents on the properties of foamed concrete to obtain high quality with a target density is nearly 1600 kg/m3. The standard samples were designed by employing two types of foam agent (FA), the first one is commercially named (EABSSOC foam agent, FA) while the second ...

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning

Advanced Intelligent Discovery, EarlyView.
This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Obtaining Foam Concrete Applying Stabilized Foam

Indian Journal of Science and Technology, 2016
Objectives: The objective of this study is to obtain better quality foam concrete. In the process of preparing proteinbased foam the technique of stabilizing foam with colloidal sol solutions is used. Methods: The idea of stabilization implies the following: The interaction at the boundaries between the foam layer phase and the colloidal sol phase ...

Aftasten/Tantear: A sensorial, coalitional wayfinding among Muslim runners

Feminist Anthropology, EarlyView.
Abstract Muslim recreational runners in Muslim‐minority settings that take up running as their preferred form of leisure indicate that they feel they have to navigate a sense of exclusion when running outdoors. This article explores the process of exploration and sensing in public, represented by the Dutch verb aftasten, to investigate the way Muslim ...
