Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

open access: yesNano Select, EarlyView.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Nonlinear elliptic equations with singularities and elliptic systems

open access: yes, 2019
This thesis is devoted to the study of nonlinear elliptic equations with homogeneous Dirichlet boundary conditions, with lower order terms that may be singular where the solution is zero and with irregular data, as well as of elliptic systems.

Numerical Simulation of Three‐Dimensional Unsteady Extrudate Swell Through Annular Dies: Effects of Die Core Opening Position and Sag on Parison Formation

open access: yesPolymer Engineering &Science, EarlyView.
Study on transient parison formation at various strokes during extrusion of Newtonian and viscoelastic fluids. In the presence of an offset between the mandrel and the bushing, Newtonian fluids exhibit a reduction in extrudate diameter, whereas viscoelastic fluids display diameter swelling only at flow rates exceeding a critical threshold.

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

open access: yesphysica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

Dynamics of Purification in Cu2O

open access: yesphysica status solidi (b), EarlyView.
Rydberg excitons in Cu2O have been shown to be highly efficient in neutralizing and screening charged impurities, which is referred to as purification. In this manuscript, the dynamics of the purification process are investigated under varying probe exciton‐ and plasma density. The transient absorption of Rydberg excitons is analyzed and five different
