Morphy: A Compliant and Morphologically Aware Flying Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents Morphy, a 25.2 cm‐wide, 260 g aerial robot with flexible, sensorized joints that enable it to withstand high‐speed collisions and squeeze through narrow spaces. Powered by an adaptive control scheme exploiting real‐time morphology feedback, Morphy demonstrates resilience in trajectory tracking, collision, and impact recovery and ...

Which institutional investors drive corporate sustainability? A systematic literature review

open access: yesBusiness Strategy and the Environment, Volume 32, Issue 1, Page 42-71, January 2023., 2023
Abstract In this article, we review recent archival research (66 studies) on the influence of institutional ownership (IO) heterogeneity on corporate sustainability. Relying on an agency‐theoretical framework, we differentiate between various types of IO and their nature.

Leveraging Noncovalent Interactions for the Binding of CO by a Weakly Lewis Acidic Borane

open access: yesAngewandte Chemie, EarlyView.
We report a carbonyl complex featuring a simple tri‐coordinate borane, characterized by a Lewis acidity which is only marginally higher than B(NMe2)3. Exposure of {(Ph2P)xanth}3B to carbon monoxide under mild conditions (1 bar, 25 °C) reversibly yields {(Ph2P)xanth}3B·CO.

PairTilt: Design and Control of an Active Tilt‐Rotor Quadcopter for Improved Efficiency and Agility

open access: yesAdvanced Intelligent Systems, EarlyView.
PairTilt is an actuated tilt‐rotor unmanned aerial vehicle capable of active shape reconfiguration, balancing simplicity, efficiency, and agility. Its H‐shaped frame incorporates pairwise tiltable rotors, which reduce gyroscopic torque and decouple key dynamics, enhancing maneuverability and reducing drag.

Aza‐Diphosphazenanes: Inorganic Cyclohexane‐like Connectors with Stereochemically Tunable Exit Vectors for Molecular and Macromolecular Chemistry

open access: yesAngewandte Chemie, EarlyView.
New aza‐diphosphinanes have been prepared and a model has been developed to explain their cis/trans isomerization. Two‐fold oxidation leads to new aza‐diphosphazenanes as robust inorganic connectors with selectable stereochemistry. Polycondensation reactions results in the first inorganic cyclo‐linear polyphosphazenes which have high‐molecular weights ...
