Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

open access: yesAdvanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

Rapid Electro‐Thermal Micro‐Actuation of Flat Optics Enabled by Laser‐Induced Graphene on Colorless Polyimide Substrates

open access: yesAdvanced Optical Materials, EarlyView.
Laser‐induced graphene (LIG) on a colorless polyimide (CPI) substrate functions as both an electrical heater and a heat spreader, enabling rapid electro‐thermo‐optic actuation. The system achieves reflective beam scanning up to 2 kHz and diffractive beam steering with 0.5‐millidegree resolution and a 0.9 s response time, showcasing LIG‐CPI as a soft ...

Reappraisal of telesurgery in the era of high‐speed, high‐bandwidth, secure communications: Evaluation of surgical performance in local and remote environments

open access: yesAnnals of Gastroenterological Surgery, Volume 7, Issue 1, Page 167-174, January 2023., 2023
This study aims to examine the feasibility of telerobotic surgery by validating the communication environment and local/remote robot operation. The performance of remote surgery over a commercial line was equivalent to that of the local environment. Therefore, remote surgery using a commercial line can be performed safely, indicating that we have the ...

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

open access: yesAdvanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

The Anomalous Acceleration of PSR J2043+1711: Long-period Orbital Companion or Stellar Flyby?

open access: yesThe Astrophysical Journal
Based on the rate of change of its orbital period, PSR J2043+1711 has a substantial peculiar acceleration of 3.5 ± 0.8 mm s ^–1 yr ^–1 , which deviates from the acceleration predicted by equilibrium Milky Way (MW) models at a 4 σ level.
