Halogen‐Bonded Liquid Crystal Elastomers as Initiator‐Free Photochemical Actuators

Advanced Materials, EarlyView.
The combination of dynamic disulfide bonds and halogen bonds in chain‐extended liquid crystal elastomers enables the fabrication of photochemical actuators without the need for a photoinitiator, advancing the design of multimodal soft actuators that can be reprogrammed and reprocessed through supramolecular functionalization.

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

Advanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

RADAR: Raman Spectral Analysis Using Deep Learning for Artifact Removal

Advanced Optical Materials, EarlyView.
RADAR is introduced, two lightweight deep learning models for artifact removal, capable of simultaneous denoising and correction of Raman spectra, significantly accelerating high‐quality data acquisition. This work advances Raman spectroscopy as a faster, more reliable tool for chemical analysis, with broad applications in materials science, biomedical

Remarriage in Finland

Finnish Yearbook of Population Research, 1988
Remarriage in Finland is examined using data for 1984. Intervals between divorce and remarriage as well as the age at remarriage are calculated and estimates are provided for the absolute number of remarried persons and the number relative to the divorced married and those living in consensual unions. It is found that "as a total somewhat more than an

Carbon‐Coated Moth‐Eye Structure: An Ultrabroadband THz‐DUV Near‐Perfect Absorber

Advanced Optical Materials, EarlyView.
A silicon moth‐eye surface coated with pyrolytic carbon achieves >98% absorption from 1 to 1200 THz by combining gradient‐index matching with PyC's broadband conductivity, forming an ultra‐broadband absorber from THz to deep UV. Experimental results and simulations agreed well.

Below 1% Reflectance for Black GaAs Surface Prepared by Facile Two‐Step Wet Chemical Treatment: Hydrogen Peroxide and Water

Advanced Photonics Research, EarlyView.
Black GaAs surface which decreases light reflectivity forms in surprising way when GaAs is kept first in hot hydrogen peroxide solution and then in hot‐water solution. To increase performance of many photonic devices (e.g., solar cell, light emitting diode (LED), photodetector), it is essential to decrease light reflection at device interfaces ...

Nonlinear Optical Microscopy of Semiconductor–Metal Nanocavities

Advanced Photonics Research, EarlyView.
Three‐dimensional nonlinear optical microscopy is used to visualize GaAs–gold hybrid nanocavities. By carefully selecting the pump wavelength to position the harmonic generation at the nanopillar resonance, an enhanced contrast is observed in the nonlinear imaging.
