Hybrid Zones

Hybrid Zones

Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

Hybridization of Atomic Orbitals I

Hybridization of Atomic Orbitals I

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Reaction Mechanisms

Reaction Mechanisms

Chemical reactions often occur in a stepwise fashion, involving two or more distinct reactions taking place in a sequence. A balanced equation indicates the reacting species and the product species, but it reveals no details about how the reaction occurs at the molecular level. The reaction mechanism (or reaction path) provides details regarding the precise, step-by-step process by which a reaction occurs.
For instance, the decomposition of ozone appears to follow a mechanism with two steps:

In-situ Hybridization

In-situ Hybridization

In situ hybridization (ISH) is a technique used to detect and localize specific DNA or RNA molecules in cells, tissue, or tissue sections using a labeled probe. The technique was first used in 1969 for the investigation of nucleic acids. It is currently an essential tool in scientific research and clinical settings, especially for diagnostic purposes.
Types of probes and labels
A probe is a complementary strand of DNA or RNA that binds to corresponding nucleotide sequences in a cell. Many...

Mechanical Protein Functions

Mechanical Protein Functions

Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Sensor Technology

Background:

Metamaterials with collective mode resonance are typically used as sensors.
Hybridized metamolecules offer unique optical properties for sensing applications.

Purpose of the Study:

To develop a Mie-based hybridized metamolecule sensor for detecting distance and applied forces.
To investigate the relationship between metamolecule coupling strength and resonance frequency shifts.

Main Methods:

Fabrication of a hybridized metamolecule with dielectric meta-atoms and an elastic bonding layer.
Analysis of hybridization-induced splitting and collective resonance modes.
Characterization of frequency shifts in response to changes in bonding layer thickness (simulating force and displacement).

Main Results:

The hybridized metamolecule exhibits two new collective resonance modes due to hybridization.
The red-shifted mode, representing in-phase oscillation, shows a deep dip with a high Q-factor and figure of merit (FoM).
Increased coupling strength, induced by external force, leads to a red-shift of the first collective mode frequency.

Conclusions:

The developed metamolecule sensor can accurately characterize tiny displacements and a wide range of applied forces.
This technology holds potential for applications in civil engineering and biological engineering.
The sensor's performance is attributed to the synergistic oscillation of meta-atoms and tunable coupling strength.
