Article Synopsis
  • Quasi-phase matching (QPM) is a technique in nonlinear optics that improves frequency conversion processes but traditionally requires specific ferroelectric crystals that are hard to obtain.* -
  • Researchers demonstrated QPM using 3R-MoS, a type of transition metal dichalcogenide with unique properties, achieving enhanced second harmonic generation (SHG) and spontaneous parametric down-conversion (SPDC) for better entangled photon pair generation.* -
  • The ability to adjust the stacking of 3R-MoS layers provides a flexible platform for tuning the phase-matching conditions, opening up new possibilities in nonlinear optics and quantum technology applications.*

Unlabelled: The Heat Shock Factor (Hsf) genes are widely distributed across the plant kingdom regulating the plant response to various abiotic stresses. In addition to natural selection, breeding and accelerated selection changed the structure and function of Hsf genes. 1076 Hsf genes from 30 genera from primitive algae to the most advanced plant species and major crop plants were used for phylogenetic analysis.

Background: The genetic base of soybean cultivars in India has been reported to be extremely narrow, due to repeated use of few selected and elite genotypes as parents in the breeding programmes. This ultimately led to the reduction of genetic variability among existing soybean cultivars and stagnation in crop yield. Thus in order to enhance production and productivity of soybean, broadening of genetic base and exploring untapped valuable genetic diversity has become quite indispensable.

Induced transparency is a common but remarkable effect in optics. It occurs when a strong driving field is used to render an otherwise opaque material transparent. The effect is known as electromagnetically induced transparency in atomic media and optomechanically induced transparency in systems that consist of coupled optical and mechanical resonators.

Characteristic for devices based on two-dimensional materials are their low size, weight and power requirements. This makes them advantageous for use in space instrumentation, including photovoltaics, batteries, electronics, sensors and light sources for long-distance quantum communication. Here we present a comprehensive study on combined radiation effects in Earth's atmosphere on various devices based on these nanomaterials.
