Probing the Atmosphere with Research Aircraft-European Aircraft Campaigns [PDF]
, 2007 - Aircraft are used to investigate the atmosphere and the ground by visual observations and by measurements with instruments on board the aircraft. They allow for: Targeted measurement of atmospheric properties above ground with in-situ instruments and with airborne remote sensing instruments along a given flight path; Measurements at high temporal ...

Advanced Materials Interfaces, EarlyView.An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

Fanwing Aircraft- Scope as an Agricultural Aircraft
International Journal for Research in Applied Science and Engineering Technology, 2021 The objective of this paper is to apply the concept of fan wing to agricultural aircrafts which are conventionally fixed wings aircrafts or multi-rotor drones. Fan wing is capable of producing good amount of lift at a sufficiently low speed without stalling, thus is apt for agricultural processes of irrigation, spraying pesticides, etc. Fan wing has a

Surface‐Anchored Microgel‐Based Films as Anti‐Icing Coatings
Advanced Materials Interfaces, EarlyView.The microgel‐based anti‐icing coatings presented in this work reduce ice adhesion by up to 90% on various substrates. This effect can be attributed to the incorporated functional cationic moieties binding a lubricating layer of quasi‐liquid interfacial water.

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.
