Molecular Domino Toppling for Directed Self‐Erasing Information Transfer

open access: yesAdvanced Materials, EarlyView.
An azobenzene‐based material with unprecedented light‐pumped directional charge‐transfer reminiscent of toppling dominoes is presented. After light‐induced trans→cis forward isomerization, electron hopping occurs in a sequential and propagating manner between the cis isomers along with an electrocatalytic cis→trans backward isomerization.

Over Tenfold Increase in Current Amplification Due to Anisotropic Polymer Chain Alignment in Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
How to boost the IDS output of an OECT? Anisotropic polymer alignment along the channel direction enables a 13‐fold increase in IDS. Such channel engineering opens the door to unprecedented signal amplification (here gmL/Wd = 2 580 S cm−1 with a PBTTT‐backbone bearing single‐ether side chains), faster ON/OFF switching, and improved stability for the ...

Discovery of an Isolated Compact Object at High Galactic Latitude

open access: yes, 2007
We report discovery of a compact object at high Galactic latitude. The object was initially identified as a ROSAT All-Sky Survey Bright Source Catalog X-ray source, 1RXS J141256.0+792204, statistically likely to possess a high X-ray to optical flux ratio.

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.
