Climate change-accelerated ocean biodiversity loss & associated planetary health impacts

open access: yesThe Journal of Climate Change and Health, 2022
A planetary health perspective views human health as a function of the interdependent relationship between human systems and the natural systems in which we live.

White Dwarf Planets from GAIA

open access: yes, 2010
We investigate the potential of high-precision astrometry with GAIA for detection of giant planetary companions to nearby white dwarfs. If one considers that, to date, no confirmed planets around single white dwarfs are known, the results from GAIA will ...

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Global models of planetary system formation in radiatively-inefficient protoplanetary discs

open access: yes, 2011
(Abridged) We present the results of N-body simulations of planetary systems formation in radiatively-inefficient disc models, where positive corotation torques may counter the rapid inward migration of low mass planets driven by Lindblad torques.

Mechanochromic, Low‐Cost, and Structurally Colored Displays Using Biodegradable Hydroxypropyl Cellulose

open access: yesAdvanced Materials, EarlyView.
Mechanochromic hydroxypropyl cellulose (HPC) integrated with microfluidic devices creates scalable, eco‐friendly reflective color displays. We demonstrate mechanochromic displays with 500 µm pixel size and 5Hz switching rates with room for optimisation. The proposed mechanochromic HPC displays are an initial step toward more environmentally responsible

Electric Field Driven Soft Morphing Matter

open access: yesAdvanced Materials, EarlyView.
This study presents soft morphing matter robots that exhibit extremely high morphological adaptability and complex multimodal electric field response. They can undergo large, controlled body deformation and show complex locomotion on different terrains under the manipulation of external electric fields, making a significant step beyond current ...

Micro‐ and Nano‐Bots for Infection Control

open access: yesAdvanced Materials, EarlyView.
This review presents a strategic vision for integrating micro‐ and nanobots in the pipeline for infection diagnosis, prevention, and treatment. To develop these robots as a practical solution for infection management, their design principles are clarified based on their propulsion mechanisms and then categorized infection management domains based on ...

Influence of Ion Size on Structure and Redox Chemistry in Na‐Rich and Li‐Rich Disordered Rocksalt Battery Cathodes

open access: yesAdvanced Materials, EarlyView.
The larger ion size of Na+ versus with Li+ has a pronounced impact on the intercalation chemistry of disordered rocksalt cathode materials. On charge, the disordered rocksalt structure is retained in Li2MnO2F but it is lost in Na2MnO2F resulting in extensive amorphization.

A Method Based on Multi-Sensor Data Fusion for Fault Detection of Planetary Gearboxes

open access: yesSensors, 2012
Studies on fault detection and diagnosis of planetary gearboxes are quite limited compared with those of fixed-axis gearboxes. Different from fixed-axis gearboxes, planetary gearboxes exhibit unique behaviors, which invalidate fault diagnosis methods ...
