Classification of Elements and Compounds02:54

Classification of Elements and Compounds

73.0K
Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond. Elements are classified as atomic or molecular based on the nature of their basic units.
Compounds are pure substances composed of two or more elements in fixed, definite proportions. Compounds are classified as ionic or molecular (covalent) based on the bonds...

CRISPR01:59

CRISPR

57.6K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Microtubules01:35

Microtubules

98.4K
There are three types of cytoskeletal structures in eukaryotic cells—microfilaments, intermediate filaments, and microtubules. With a diameter of about 25 nm, microtubules are the thickest of these fibers. Microtubules carry out a variety of functions that include cell structure and support, transport of organelles, cell motility (movement), and the separation of chromosomes during cell division.

The Nucleolus02:55

The Nucleolus

10.3K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Intermolecular vs Intramolecular Forces

96.5K
Intermolecular forces (IMF) are electrostatic attractions arising from charge-charge interactions between molecules. The strength of the intermolecular force is influenced by the distance of separation between molecules. The forces significantly affect the interactions in solids and liquids, where the molecules are close together. In gases, IMFs become important only under high-pressure conditions (due to the proximity of gas molecules). Intermolecular forces dictate the physical properties of...

Area of Science:

  • Plasmonics and Photonics
  • Materials Science

Background:

  • Ferromagnetic nickel (Ni) nanodisks exhibit plasmonic resonances but suffer from significant ohmic losses.
  • Organic gain media can provide optical gain but require efficient coupling to plasmonic structures.

Purpose of the Study:

  • To demonstrate visible lasing in arrays of Ni nanodisks coupled with an organic gain medium.
  • To investigate the compensation of plasmonic losses and the characteristics of the emitted light.
  • To explore tunable multimode lasing by breaking array symmetry.

Main Methods:

  • Fabrication of ferromagnetic Ni nanodisk arrays.
  • Overlaying nanodisks with an organic gain material.
  • Optical pumping and spectral analysis of emission.
  • Symmetry breaking in nanodisk arrays.

Main Results:

  • Achieved lasing at visible wavelengths by compensating Ni nanodisk plasmonic losses with organic gain.
  • Observed a transition from spontaneous emission to highly directional, sub-nanometer linewidth lasing with increasing pump fluence.
  • Demonstrated tunable multimode lasing at two distinct wavelengths by breaking array symmetry.

Conclusions:

  • Integration of organic gain media with Ni nanodisks effectively compensates for plasmonic losses, enabling visible lasing.
  • The developed system offers tunable multimode lasing, relevant for applications in magnetoplasmonic devices and topological photonics.
