Deformations in a Symmetric Member in Bending01:18

Deformations in a Symmetric Member in Bending

When analyzing the deformation of a symmetric prismatic member subjected to bending by equal and opposite couples, it becomes clear that as the member bends, the originally straight lines on its wider faces curve into circular arcs, with a constant radius centered at a point known as Point C. This phenomenon helps to understand the stress and strain distribution within the member more clearly.
When the member is segmented into tiny cubic elements, it is observed that the primary stress...
Cleavage and Blastulation01:33

Cleavage and Blastulation

After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.
Deformation in a Circular Shaft01:10

Deformation in a Circular Shaft

One of the distinctive characteristics of circular shafts is their ability to maintain their cross-sectional integrity under torsion. In other words, each cross-section continues to exist as a flat, unaltered entity, simply rotating like a solid, rigid slab. To understand the distribution of shearing stress within such a shaft, consider a cylindrical section inside this circular shaft. This section has a length of L and a radius of R, with one end fixed. The radius of the cylindrical section is...

Ionic Crystal Structures02:42

Ionic Crystal Structures

Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
Simple Trusses01:21

Simple Trusses

A truss is a structural framework consisting of slender members connected at joints, designed to support external loads while minimizing material usage and weight. Simple trusses are a type of planar truss where all members lie within a single two-dimensional plane.
The most basic planar truss is a simple truss with three members arranged in a triangular formation. This triangular truss is inherently stable and rigid due to its geometry, making it an ideal starting point for creating more...

Area of Science:

  • Nanotechnology
  • Materials Science
  • Physical Chemistry

Background:

  • Surface plasmon resonance (SPR) is crucial for nanomaterial optical properties.
  • Controlling SPR in noble metal nanostructures is key for advanced applications.

Purpose of the Study:

  • To synthesize and characterize novel gold-core silver-shell (Au-Ag) triangular bifrustum nanocrystals.
  • To investigate the origin of tunable surface plasmon resonances in these nanostructures.

Main Methods:

  • Seed-mediated synthesis in aqueous solution.
  • Characterization using transmission electron microscopy (TEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), and energy-dispersive spectrometry (EDS).
  • Discrete dipole approximation (DDA) calculations for theoretical analysis.

Main Results:

  • Successfully synthesized Au-Ag triangular bifrustum nanocrystals.
  • Observed highly tunable dipole and quadrupole surface plasmon resonances.
  • DDA calculations confirmed that nanocrystal geometry, not elemental composition, dictates plasmon tunability.

Conclusions:

  • The geometric configuration of Au-Ag bifrustum nanocrystals is the primary factor for tunable plasmon resonances.
  • This study provides a pathway for designing nanomaterials with tailored optical properties.
