Directional Whispering Gallery Mode in Microring Lasers Enabled by Tilted Azimuthal Gratings
The chiral light propagation in microring lasers with active cladding, enabled by tilted azimuthal gratings, is illustrated. The symmetry of the whispering gallery mode is disrupted due to scattering losses that are determined by the tilted angle, resulting in distinct clockwise and counterclockwise light propagation, and enabling controlled chirality ...

A freestanding ZnO nanorod array on carbon cloth (ZnO/CC) is synthesized via hydrothermal growth and studied during its electrochemical reduction to Zn. Advanced characterization techniques (SEM, HRTEM, and STXM) reveal the morphochemical evolution of ZnO nanorods, providing unprecedented insights into the ZnO‐to‐Zn conversion mechanism.

An Analysis of Elusive Relationships in Floating Zone Growth Using Data Mining Techniques
Ultra‐pure silicon single‐crystals can be grown by the Floating Zone (FZ) method. This study investigates intricate relationships between process stability measures and multiple growth parameters by applying data mining techniques on FZ simulations. Regression Trees identified multivariate relationships that help explaining complex interactions between

Metallicity of Globular Cluster NGC 5053 from VI CCD Photometry [PDF]
Red giant branch shape and the luminosity of horizontal branch on the (V-I)-V CMD are used to derive the metallcity of the globular cluster NGC 5053. The metallicities of NGC 5053 derived by SMR method ([Fe/H]=-2.62+-0.07) and the relation between [Fe/H]

Globular Clusters and Horizontal Branch
An analysis of available Galactic globular cluster data on metallicity, ages, the distribution of stars on the horizontal branch and the distribution of the periods of RR0 Lyr variables showed that: 1. The latter two characteristics can be used for determining the Oosterhoff type. 2.
