Preparation of Ag/Au Bimetallic Nanodecahedra through Galvanic Displacement Method
Tập 41 Số 1 - Trang - 2025
In this work, Ag/Au bimetallic nanodecahedra was successfully synthesized using
the reduction process and photochemical method. Polyvinylpyrrolidone was used as
a shape-directing agent, AgNO3, HAuCl4 as precursor raw materials, sodium
borohydride as a reducing agent for the growth of Ag metal. Ag+ ions were
reduced to Ag nanoparticles (AgNPs) as seeds using sodium borohydride (NaBH4),
and then Ag ...
Indentation Response of the Auxetic Bone-inspired Cellular Structure Materials
Tập 41 Số 2 - Trang - 2025
in this work we investigate the indentation response of the auxetic cellular
structure materials. The auxetic cellular structure material is selected as the
newly bone-inspired cellular structure material. The elastic material properties
of this material are characterized by nine elastic constants. Thus, to study the
indentation responses of the auxetic bone-inspired cellular structure materials,
...
Spheric Aberration Evaluation of Thin Lens by Ray Transfer Matrix
- Trang - 2024
The spheric aberration is one of the optical aberration influencing on the
optical quality of the optical system, specially, the objective. In this paper,
we poropose to use the rays transfer matrix to evaluate the spheric aberration
of the nonparaxial rays. Basing on the element cofiguration of the thin lens, we
introduce the rays transfer matrix describing the relation the object’s and
image’s h...
Numerical Investigation of Optical Properties in Carbon Tetrachloride-Filled Photonic Crystal Fibers
Tập 39 Số 4 - Trang - 2023
In this work, we design circular lattice photonic crystal fibers using Lumerical
Mode Solution software, its hollow core filled with carbon tetrachloride.
Optical properties including effective refractive index, chromatic dispersion,
nonlinearity, and fiber loss were investigated numerically in detail based on
solving Maxwell's wave equations. The small effective mode areas of only a few
µm2, and ...
Characterizations of Cr3+- doped SnO2 Powders Via a Hydrolysis Method
Tập 39 Số 4 - Trang - 2023
In this work, the effect of annealing temperature and Cr3+ concentration on the
structural and optical properties of the SnO2 host crystals has been
investigated. The Cr-doped SnO2 samples were synthesized by a simple hydrolysis
method, using SnCl4.5H2O as the host precursor and CrCl3.6H2O as the source of
dopant. X-ray diffraction and Raman scattering spectra analysis revealed a
tetragonal rutile...

Phenomenological Analogy between Gross-Pitaevskii Theory for Bose-Einstein Condensate and Newton Equation for Classical Mechanics
Tập 40 Số 2 - Trang - 2024
In this work we found an interesting analogy between Gross-Pitaevskii theory for
Bose-Einstein condensate at zero temperature and Newton equation of classical
particle in the classical physics. Although this analogy is a pure
phenomenology, it brings a new perspective to physics in general, in particular
to quantum physics, as well as to many-body physics.

Equation Chapter 1 Section 1 Concentration Inequality for m-dependent Random Vectors in Hilbert Spaces
Tập 41 Số 2 - Trang - 2025
Let be a sequence of -dependent random vectors taking values in a real
separable Hilbert space. In this work we introduce concentration inequality for
the partial sums of . Then, we give the weak laws of large numbers for weighted
sums of .
