Disequilibrium Carbon, Oxygen, and Nitrogen Chemistry in the Atmospheres of HD 189733b and HD 209458b

open access: yes, 2011
We have developed 1-D photochemical and thermochemical kinetics and diffusion models for the transiting exoplanets HD 189733b and HD 209458b to study the effects of disequilibrium chemistry on the atmospheric composition of "hot Jupiters." Here we ...

Room‐Temperature, High‐Resolution Soft Anisotropic Conductive Film for Electrical Interfacing in Stretchable Electronics

open access: yesAdvanced Functional Materials, EarlyView.
A UV‐crosslinkable soft anisotropic conductive film (ACF) provides high‐resolution, room‐temperature electrical interfacing. Upon UV exposure, azide crosslinkers within the ACF matrix form covalent bonds with a wide range of C–H‐containing materials, resulting in interfaces that are both mechanically durable and electrically reliable.

Endowing single-crystal polymers with circularly polarized luminescence

open access: yesNature Communications
The preparation of single-crystal polymers with circularly polarized luminesce (CPL) remains a challenging task in chemistry and materials science. Herein, we present the single-crystal-to-single-crystal topochemical photopolymerization of a chiral ...

Strain‐Activated Photo‐Dehalogenation Unlocks Low‐Energy One and Two‐Photon 3D Microfabrication

open access: yesAdvanced Functional Materials, EarlyView.
5,14‐NMI‐Cz acts, conversely to its 7,10‐NMI‐Cz(7,10‐'dibromo‐2‐(2,6‐diisopropylphenyl)‐1H‐benzo[lmn]carbazolo[9,1‐bc][2,8]phenanthroline‐1,3(2H)‐dione) counterpart, as modular photoinitiator with panchromatic photoactivity, featuring a weak C–Br bond from geometric strain for efficient Type I & II initiation. These studies demonstrate applicability of

Bioinspired Design of a Wet‐Adhesive Cornea Glue Based on Recombinant Human Protein Networks

open access: yesAdvanced Functional Materials, EarlyView.
Natures protein‐based high performance materials e.g. elastin, silk and muscle proteins have been mimicked by a new protein‐hybrid material based on redesigned human partial sequences only, showing high wet‐adhesiveness and elasticity for biomedical applications.

Bistable Photochromic Guest–Host Liquid Crystals for Rewritable and Switchable Photonic Devices

open access: yesAdvanced Functional Materials, EarlyView.
A photochromic DTCP‐based liquid crystal dye is incorporated into cholesteric liquid crystals (CLCs) to achieve optically and electrically tunable multistable states. In the open‐ring form, the system exhibits three electrically stable textures—planar, focal conic, and uniformly lying helix (ULH)—corresponding to reflective, scattering, and transparent

Flow photochemistry: Old light through new windows

open access: yesBeilstein Journal of Organic Chemistry, 2012
Synthetic photochemistry carried out in classic batch reactors has, for over half a century, proved to be a powerful but under-utilised technique in general organic synthesis.
