Ultrasmall High‐Entropy Materials: Nanoscale Effects, Synthesis, and Mechanistic Insights

Advanced Functional Materials, EarlyView.
This review article focuses on sub‐10 nm high‐entropy materials that combine nanoscale design with complex compositions for next‐generation applications. ABSTRACT Ultrasmall high‐entropy nanomaterials (USHENMs, <10 nm) merge multicomponent chemistry with size‐dependent effects, forming a distinct class of materials with unprecedented properties.

Vibrations of circular cylindrical shells [PDF]

, 1975
An exact solution method for the free vibration problem of thin circular cylindrical shells is presented. The differential equations of motion are solved directly with the use of simple Fourier series as the modal displacement functions. Stokes' transformation is exploited to obtain correct series expressions for the derivatives of the Fourier series ...

Targeting Post‐Irradiation Thyroid Dysfunction: Electrospun Scaffolds As A Dual‐Action Approach for Antioxidant and Immune Modulation

Advanced Healthcare Materials, EarlyView.
Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...

Analytical Calculation of Cylindrical Shells in the Form of Second-Order Algebraic Surfaces

Structural Mechanics of Engineering Constructions and Buildings
When choosing the shape of a shell, one should strive for the boundary conditions to ensure momentless behavior of the shell. Second-order algebraic surfaces include three degenerate surfaces: parabolic, elliptic, and hyperbolic cylindrical surfaces, and

Dynamic response of unsupported and supported cavities in an elastic half-space under moving normal and torsional loads

Қарағанды университетінің хабаршысы. Физика сериясы, 2023
This study explores the impact of uniformly moving normal and torsional loads along an infinitely long circular cylindrical cavity, situated within a half-space (body), on the behavior of the elastic half-space.

Steady-State Creep of Circular Cylindrical Shells

Bulletin of JSME, 1970
Steady-state creep of simply supported circular cylindrical shells with open ends under internal pressure is analysed numerically by the extended Newton method combined with the method of finite-difference. Creep theory of Mises type and power creep law are assumed. Numerical calculation is carried out for long and short shells with creep exponents n=1

Modeling Acoustic Emission Due to an Internal Point Source in Circular Cylindrical Structures

Applied Sciences, 2022
In one of our previous publications, we developed the first mathematical model for acoustic emission from an internal point source in a transversely isotropic cylinder. The point source, as an internal defect, is the most fundamental source generating AE
