Ferrocene‐Based Self‐Assembled Monolayers Enable Ultra‐High Specific Detectivity in Perovskite Photodetectors

open access: yesAdvanced Materials, EarlyView.
We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Nonplanar Bouligand Architectures for Enhanced Mechanical Performance in Cementitious Composites

open access: yesAdvanced Materials, EarlyView.
Inspired by the impact region of the Mantis shrimp dactyl club, nonplanar additive manufacturing translates sinusoidal Bouligand architectures into cementitious composites. Printing‐induced anisotropy and architected interfaces promote distributed damage and arrest crack propagation, enhancing strength and energy absorption.

A novel objective no-reference metric for digital video quality assessment

open access: yes, 2005
A novel objective no-reference metric is proposed for video quality assessment of digitally coded videos containing natural scenes. Taking account of the temporal dependency between adjacent images of the videos and characteristics of the human visual ...

Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions

open access: yesAdvanced Materials, EarlyView.
This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

pH‐Responsive Synthetic Cells for Programmable In Situ Protein Synthesis and Release

open access: yesAdvanced Materials, EarlyView.
A synthetic cell is engineered to convert environmental acidification into nucleic acid signaling that activates protein synthesis. By coupling proton‐channel sensing, pH‐responsive DNA transduction, and toehold‐regulated translation, the platform enables acid‐triggered protein production within hydrogel‐embedded synthetic cells.

QMET: A new quality assessment metric for no-reference video coding by using human eye traversal

open access: yes, 2016
The subjective quality assessment (SQA) is an ever demanding approach due to its in-depth interactivity to the human cognition. The addition of no-reference based scheme could equip the SQA techniques to tackle further challenges.

A Coaxial Bioprinted Hydrogel With Semipermeable Sheath and Pro‐Chondrogenic Core for Articular Cartilage Repair

open access: yesAdvanced Materials, EarlyView.
A sheath‐core biomimetic hydrogel is engineered with a compartmentalized yet integrated architecture for synergistic multifunctionality. Its stiff, semipermeable sheath mimics the ECM's load‐bearing and protective roles, encapsulating a soft core that provides a pro‐chondrogenic microenvironment similar to the PCM.
