Micro‐Transfer Printed Continuous‐Wave and Mode‐Locked Laser Integration at 800 nm on a Silicon Nitride Platform

Laser &Photonics Reviews, EarlyView.
A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems

Laser &Photonics Reviews, EarlyView.
This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

From Computational Screening to Enhanced Adsorption: Optimized Removal of Toxic Congo Red by Nitrogen‐rich Triazine Polymers

Macromolecular Materials and Engineering, EarlyView.
This study validates a DFT‐employed screening approach for discovering new adsorbent materials for organic dyes, successfully identifying CCTAT POP as a highly effective adsorbent for Congo red dye. The POP material exhibits a superior adsorption capacity (46.51 mg g−1) and maintains a regeneration ability, achieving over 90% removal efficiency in ...

Exploration of Therapeutic Targets Using CDK4 Inhibitors for Head and Neck Mucosal Melanoma

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Mucosal melanoma (MM) is an extremely aggressive malignant tumor in the head and neck region associated with a poor prognosis. In the present study, we conducted cell proliferation assay and western blotting using cell lines derived from MM and the immunohistochemical analysis of pathological MM tissues to identify novel therapeutic ...

Cyanoacetamidobetaine—A Zwitterionic Nitrile Derivative

ChemistryOpen, EarlyView.
The reaction of sodium dicyanamide with betainium chloride in aqueous solution affords N‐cyano‐2‐(trimethylammonio)acetaminide (cyanoacetamidobetaine). Single crystal X‐ray diffraction reveals a monoclinic structure comprising a trimethylammonium head group connected to a cyanoacetaminide unit via a methylene bridge.

Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...
