The optimal modes of isovalent substitution and the CdTe/CdS/ZnS heterostructure obtained for the first time were established, the main parameters of the band structure of the constituent heterolayers and the characteris...

Precise manipulation of Bragg reflection in cholesteric liquid crystals (CLCs) is essential for advancing reconfigurable optics. However, existing photo-responsive material-doped CLC technologies that rely on single-wave...

Light encodes information in multiple degrees of freedom (e.g., frequency, amplitude, and phase), enabling high-speed, high-bandwidth communication through fiber optics. Unlike classical light, quantum light (single or e...

Nonlinear optical effects such as frequency conversion form the basis for many practical light sources. In a variety of settings, the performance of such sources is limited by quantum noise. In many nonlinear systems, th...

Acne vulgaris is a chronic inflammatory skin condition with a high global prevalence. Light-based therapies can be used in acne treatment on account of their good safety profile, lack of potential for developing resistan...

Double-rf systems have become a standard solution in advanced storage ring light sources for beam acceleration and bunch lengthening. In this context, a compact single-cell normal-conducting bimodal rf cavity is proposed...

The military conflict that started in the Donbas in 2014, which, in 2022, turned into a full-scale Russo-Ukrainian war, has created a specific way in which it is remembered. This article is based on more than sixty int...

The Egyptological core of Plutarch's De Iside et Osiride was last scrutinized by a competent scholar in 2000; as it was part of a Romanian-language dissertation which was never released in print and only recently put ope...

The Dielectric Barrier Discharge (DBD) Excimer Ultra-Violet (UV) lamps are a promising technology offering several advantages over other sources of UV light. In particular, the application of this type of lamps for drink...

Photonic metasurfaces, that is, two-dimensional arrangements of designed plasmonic or dielectric resonant scatterers, have been established as a successful concept for controlling light fields at the nanoscale. While the...

Over the past two decades, two-dimensional (2D) van der Waals (vdW) semiconductors have garnered significant attention in the field of light sources due to their unique optoelectronic properties, such as high excitonic b...
