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.

Radiological criteria for remedial actions at radioactively contaminated sites. Environmental Restoration Program [PDF]

, 1994
Radiological criteria for determining acceptable remedical actions at radioactively contaminated sites on the Oak Ridge Reservation are presented in this report. The proposed criteria address protection of human health and man`s exposure environment but do not address protection of nonhuman biota.

Size-dependent mitigation by humic acid: rescuing metabolic homeostasis from nano-plastics but not micro-plastics in Microcystis aeruginosa

Frontiers in Environmental Science
Microplastics (MPs) are ubiquitous freshwater contaminants, yet their combined effects with humic acid (HA) on phytoplankton remain poorly understood. This study investigated the physiological and metabolic responses of Microcystis aeruginosa exposed to ...

Biomimetic Self‐Reconfigurable Soft Gripper for Cross‐Scale, Multi‐Particle, and High‐Load Multifunctional Manipulation

Advanced Science, EarlyView.
A fully soft, self‐reconfigurable gripper inspired by rapeseed flowers is monolithically 3D‐printed and electronics‐free, switching between diagonal and parallel finger arrangements. Establishing a self‐reconfigurable grasping paradigm, the gripper enables diverse manipulation tasks, including rotating bulbs, picking fruits, grasping cross‐scale ...
