Light‐Harvesting Nanomaterials Based on Dyes for Energy Transfer and Amplified Biosensing

open access: yesAdvanced Materials, EarlyView.
Light harvesting (LH) in plants inspires researchers to develop artificial LH nanomaterials. Here, LH nanomaterials based on organic dyes are reviewed, considering fundamental challenges on aggregation‐caused quenching, excitation energy transfer, and exciton migration length.

A modified model for laser-cornea interaction following the ablation effect in the laser eye-surgery

open access: yesBeni-Suef University Journal of Basic and Applied Sciences, 2023
Background Laser corneal reshaping is a successful treatment of many refraction disorders. However, some physical demonstrations for the laser interaction with cornea are not fully explained. In the current paper, we present a modified model to precisely

Endocardial photoablation by excimer laser

open access: yesJournal of the American College of Cardiology, 1986
A xenon-chlorine excimer laser was used to irradiate normal endocardium of fresh sheep and pig hearts as well as unfixed human endocardial scar. Forty pulses of 370 J and 35 ns each resulted in penetration of up to 12 mm in normal tissue and only 3.5 mm in scarred endocardium.

Atomically‐Thin Freestanding Racetrack Memory Devices

open access: yesAdvanced Materials, EarlyView.
Ultrathin and flexible freestanding racetrack membranes are fabricated using a water‐soluble Sr3Al2O6 release layer, without a buffer between the release layer and the magnetic heterostructure. The absence of any buffer layer enables local modulation of the current‐ and field‐induced manipulation of the racetrack magnetization via direct coupling with ...

Janus‐Type Photophysics of Rotational Isomers in a Diphenylanthracene Dimer

open access: yesAngewandte Chemie, EarlyView.
To fully grasp the genuine photophysical landscape of organic molecules, we must consider conformational isomerism arising from structural flexibility. Or else, this may mislead diverse mixtures of conformers to be assigned as a single ensemble. This work demonstrates Janus‐type photophysics of rotamers in a diphenylanthracene dimer, highlighting ...

Multiplex electric discharge gas laser system [PDF]

open access: yes, 1987
A multiple pulse electric discharge gas laser system is described in which a plurality of pulsed electric discharge gas lasers are supported in a common housing. Each laser is supplied with excitation pulses from a separate power supply.

High‐Throughput Design of Epitaxial Orientation for Functional Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
A high‐throughput strategy is proposed to screen buffer layer parameters for epitaxial growth. Using PbZr1‐xTixO3 as a model system, the optimal CoFe2O4 thickness enables the growth of [111]‐oriented PbZr0.2Ti0.8O3 thin film on Mica(001) substrate.

Alopecia Totalis Treated with 1064 nm Picosecond Nd:YAG Laser: A Case Report

open access: yesApplied Sciences, 2019
Alopecia areata (AA) is an autoimmune disorder causing nonscarring hair loss. Alopecia totalis (AT), the severe form of AA, is usually refractory to many first-line treatments including topical and intralesional corticosteroids and topical immunotherapy.

Microwave pumped excimer lasers

open access: yesConference on Lasers and Electro-Optics, 1981
Microwave excitation is a simple practical method of pumping high-pressure rare-gas-halide laser systems which avoids the discharge instabilities of typical avalanche discharges. Thus long pulse high-repetition rate operation is possible. In addition, the device can be easily constructed with high-vacuum halogen compatible materials and is free from ...

Disrupting J‐Aggregation in Triazatruxene Dimers to Develop Responsive Luminescent Inks for Anti‐Counterfeiting Applications

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...
