Strong Second‐Order Nonlinear Optical Activities in Chiral Hybrid Copper(I) Bromide Microplates

ABSTRACT Organic–inorganic chiral hybrid metal halides (HMHs) with efficient second‐order nonlinear optical responses are promising for various photonic applications. However, chiral HMHs that simultaneously deliver strong second‐harmonic generation (SHG) and pronounced nonlinear...

Fiber Electronics: Integrating Logic, Photodetection, and Wireless Communication on a Single Optical Fiber

Abstract Optical fibers underpin the global information infrastructure, yet their role has remained largely passive—restricted to guiding light rather than processing it. Signal modulation, detection, and logic operations are still performed by external chips, imposing fundamenta...

The Perceived Value of Risk Reduction Programs in High-Risk Areas in Malaysia

This paper aims to evaluate the perceived value of the drug prevention activities in Malaysia's high-risk areas. The drug prevention activities involved are counseling, outreach, workshop, and program. A quantitative method is employed in this study to investigate the participant...
