Scaling Up Purcell‐Enhanced Self‐Assembled Nanoplasmonic Perovskite Scintillators into the Bulk Regime

open access: yesAdvanced Materials, EarlyView.
This study presents a scalable approach to enhancing bulk scintillators using nanoplasmonics. By integrating 100‐nm silver nanoparticles with perovskite scintillator nanocrystals in a polymer matrix, significant improvements in light yield and decay rates via the Purcell effect are achieved.

MitraClip for the treatment of heart failure with mitral regurgitation: A cost-effectiveness analysis in a Chinese setting

open access: yesFrontiers in Cardiovascular Medicine, 2022
BackgroundHeart failure (HF) with mitral regurgitation is associated with decreased survival. Guideline-directed medical therapy and transcatheter edge-to-edge repair (TEER) are the main options for HF patients with severe mitral regurgitation who are ...

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

Full Wafer Scale Manufacturing of Directly Printed TiO2 Metalenses at Visible Wavelengths with Outstanding Focusing Efficiencies

open access: yesAdvanced Materials, EarlyView.
The highest experimentally determined focusing efficiency is reported here by using the direct imprinting of all‐inorganic TiO2 metalens arrays. Absolute efficiency greater than 80% and relative efficiency greater than 90% are achieved by optimization of all fabrication parameters controllable in the additive manufacturing process.

Uni‐Axial Densification of Slurry‐Casted Li₆PS₅Cl Tapes: The Role of Particle Size Distribution and Densification Pressure

open access: yesAdvanced Materials, EarlyView.
Solid‐state batteries promise high energy density and safety for electric vehicles. This study examines the densification of slurry‐casted Li₆PS₅Cl separator tapes, highlighting the role of particle size distribution and uni‐axial pressure. Wet milling refines particles while preserving conductivity, and a critical compaction threshold leads to ...

Towards Meta-learning over Data Streams [PDF]

open access: yes, 2014
Modern society produces vast streams of data. Many stream mining algorithms have been developed to capture general trends in these streams, and make predictions for future observations, but relatively little is known about which algorithms perform ...

Advanced Electrode Materials for Efficient Hydrogen Production in Protonic Ceramic Electrolysis Cells

open access: yesAdvanced Materials, EarlyView.
Protonic ceramic electrolysis cells (PCECs) are a promising intermediate‐temperature hydrogen production technology, leveraging high proton conductivity in electrolytes yet constrained by insufficient catalytic activity and interfacial instability in fuel/air electrodes. This review systematically categorizes advanced electrode materials and critically

Catalytically Active Light Printed Microstructures

open access: yesAdvanced Materials, EarlyView.
The fabrication of micro‐ and macro‐scale 3D‐printed multi‐material structures incorporating photocatalytically active Ru(II) sites using a dual‐function photoresin is introduced. The system utilizes a Ru(II)‐functionalized monomer, enabling the assembly of 3D structures with commercially available crosslinkers.
