Nanographene‐Based van der Waals Organic Framework With Permanent Porosity

open access: yesAngewandte Chemie, EarlyView.
Unlocking record‐breaking porosity in a supramolecular organic framework (SOF). Through the strategic design of a C3‐symmetric nanographene, a robust supramolecular framework is achieved via exclusively weak van der Waals forces. This metal‐free scaffold reaches a benchmark BET surface area of 1108 m2 g−1 –the highest to date for this class–combining ...

Impact of chromatic surround on display perception

open access: yes, 2008
Perceptual changes in colors on a display due to highly chromatic surrounds were examined. While classical experiments showed that achromatic surround luminance levels impact contrast response, here hue and chroma of the surround were also varied.

In Situ Confinement of 0D Halometallates Within Deep Eutectic Solvents: From Systematic Screening to Metal‐Tunable Luminescence for Anti‐Counterfeiting Eutectogels

open access: yesAdvanced Science, EarlyView.
We report photostable, photoluminescent deep eutectic solvents (DESs) powered by in situ‐formed zero‐dimensional (0D) halometallates. Stabilized by microenvironment‐controlling hydrogen bond acceptor (HBA) and donor (HBD) networks, these DESs exhibit vibrant, metal ion‐tunable emission (PLQY = 60.2%).

Enhancing the soft proofing paradigm [PDF]

open access: yes, 2007
The first part of this study is devoted to assessing the suitability of soft proofs as a surrogate for the final print in judging colour-reproduction quality. Two sets of psychophysical experiments were carried out.

Generation of Self‐Organizing Macrovascular Constructs by Bioprinting Human iPSC‐Derived Mesodermal Progenitor Cells

open access: yesAdvanced Science, EarlyView.
ABSTRACT Vascularization remains a major obstacle in tissue engineering. Here, we introduce a bioprinting strategy to generate centimeter‐scale, self‐organizing “mother vessel” constructs from iPSC‐derived hiMPCs. By optimizing bioink composition, printing was accomplished in a single‐step approach. Within one week, hiMPCs differentiated into both CD31+

Temperature‐ and Light‐Regulated Liquid Crystal Smart Window for Dynamic Control of Daylight and Solar Heat in All‐Weather Conditions

open access: yesAngewandte Chemie, EarlyView.
An environmentally adaptive smart window based on the interplay of light‐driven molecular motors and liquid crystal (LC) polymers is developed. The window can dynamically switch among three distinct working states: transparent, reflective, and scattering, depending on ambient temperature and solar light intensity, enabling excellent modulation of ...

High-fidelity colour reproduction for high-dynamic-range imaging

open access: yes, 2010
The aim of this thesis is to develop a colour reproduction system for high-dynamic-range (HDR) imaging. Classical colour reproduction systems fail to reproduce HDR images because current characterisation methods and colour appearance models fail to ...

Online chromatic and scale-space microvessel-tracing analysis for transmitted light optical images [PDF]

open access: yes, 2012
Limited contrast in transmitted light optical images from intravital microscopy is problematic for analysing tumour vascular morphology. Moreover, in some cases, changes in vasculature are visible to a human observer but are not easy to quantify. In this

Dynamic Evolution‐Controlled Parabolic‐Shaped Microstructures for Ultra‐Black Surface via Self‐Assembled Microsphere Mask Etching

open access: yesAdvanced Science, EarlyView.
A robust, substrate‐independent fabrication approach overcomes the spectral and geometric limitations of traditional stray‐light suppression. By combining ink spray‐coating with self‐assembled microsphere mask etching, this method produces parabolic‐shaped microstructures on diverse planar and curved engineering components.
