Differential impact of 0.01% and 0.05% atropine eye drops on visual performance in young adults.

Purpose: The onset and progression of myopia can occur during adulthood, suggesting that myopia should be managed in young adults. Low-concentration atropine eye drops have shown promising efficacy in myopia control. This study aimed to evaluate the impact of 0.

Achieving Ultrahigh Photoluminescence Quantum Yield in Highly Stable CsCuI Perovskite Single Crystals Through Melt Growth.

Low-dimensional halide perovskites CsCuI have garnered increasing attention for their exceptional luminescent properties, attributed to their stability, high photoluminescence quantum yield (PLQY), and scintillation efficiency. Here, we report the growth of transparent CsCuI crystals via the Bridgman method, emphasizing precise control of melt stoichiometry for optimal performance. Through melt composition optimization, significant improvements in crystal clarity and structural integrity were achieved, enhancing transmittance from 30% to over 80% and achieving nearly 100% PLQY.

Selenophosphate PbPSe Single Crystals Growth by Chemical Vapor Transport (CVT) Method for Radiation Detection.

The heavy metal selenophosphate PbPSe emerges as a promising room-temperature X-ray/γ-ray detectors due to its high resistivity, robust radiation-blocking capability, and outstanding carrier mobility-lifetime product, etc. However, the high activity of phosphides poses significant impediment to the synthesis and single crystal growth. In this work, we have prepared high-quality PbPSe single crystals with using the chemical vapor transport (CVT) method.

Differential Impact of 0.01% and 0.05% Atropine Eyedrops on Ocular Surface in Young Adults.

Purpose: To evaluate the effect of low-concentration (0.01% and 0.05%) atropine eyedrops on ocular surface characteristics in young adults.

Effects of Spectacle Lenses With Aspherical Lenslets on Peripheral Eye Length and Peripheral Refraction in Myopic Children: A 2-Year Randomized Clinical Trial.

Purpose: To investigate changes in peripheral eye length (PEL) and peripheral refraction (PR) in myopic children after wearing spectacle lenses with highly or slightly aspherical lenslets (HAL or SAL) for 2 years.

Methods: We recruited 170 children aged 8 to 13 years with myopia between -0.75 diopters (D) and -4.

High-Performance Industrial-Grade CsPbBr Single Crystal by Solid-Liquid Interface Engineering.

All-inorganic metal halide perovskite CsPbBr crystal is regarded as an attractive alternative to high purity Ge and CdZnTe for room temperature γ-ray detection. However, high γ-ray resolution is only observable in small CsPbBr crystal; more practical and deployable large crystal exhibits very low, and even no detection efficiency, thereby thwarting prospects for cost-effective room temperature γ-ray detection. The poor performance of large crystal is attributed to the unexpected secondary phase inclusion during crystal growth, which traps the generated carriers.

Myopia Control Efficacy of Spectacle Lenses With Aspherical Lenslets: Results of a 3-Year Follow-Up Study.

Purpose: To investigate myopia control efficacy in children who continued wearing spectacle lenses with highly aspherical lenslets (HAL) or switched from spectacle lenses with slightly aspherical lenslets (SAL) and single-vision spectacle lenses (SVL) to HAL for 1 year after a 2-year myopia control trial.

Design: This was a 1-year extension of a randomized clinical trial.

Methods: Of 54 children who had worn HAL for 2 years, 52 continued wearing HAL (HAL1 group), and of the 53 and 51 children who had originally worn SAL or SVL, 51 and 48 switched to wearing HAL (HAL2 and HAL3 groups) in year 3, respectively.

High-Quality GaSe Single Crystal Grown by the Bridgman Method.

A high-quality GaSe single crystal was grown by the Bridgman method. The X-ray rocking curve for the studied GaSe sample is symmetric and the Full Width at Half Maximum (FWHM) is only 46 arcs, which is the smallest value ever reported for GaSe crystals. The IR-transmittance is about 66% in the range from 500 to 4000 cm.
