Comparison of finite and boundary element methods in problems of oscillations of a composite shell of revolution with a liquid

Вісник Харківського національного університету імені В.Н. Каразіна. Серія: Математичне моделювання, інформаційні технології, автоматизовані системи управління, 2019
The phenomenon of sloshing can be described as the movement of the free surface of a liquid contained in a reservoir under the action of a suddenly applied load.

Correlated Metal LaNiO3 as a p‐Type Transparent Conductor

Advanced Functional Materials, EarlyView.
p‐type transparent conducting oxides are needed to enable superstrate solar cell geometries with n‐type absorbers. The p‐type correlated metal LaNiO3 combines high optical transmission with low electrical resistivity and is compatible with a range of scalable deposition processes.

Tuning Redox Dynamics in Cu‐Based Electrocatalysts: Effect of Secondary Metals

Advanced Functional Materials, EarlyView.
Advanced analysis of operando X‐ray absorption spectroscopy data reveals that secondary metals affect the redox processes in Cu‐based catalysts for electrocatalytic CO2 reduction. This influences the amount of oxides formed under pulsed reaction conditions and the distribution of reaction products.

Liquid vibration modeling in prismatic tanks with quarter baffles

Вісник Харківського національного університету імені В.Н. Каразіна. Серія: Математичне моделювання, інформаційні технології, автоматизовані системи управління, 2019
Free vibrations of liquid in a rigid prismatic tank with vertical cross partitions are considered. These partitions divide the tank into four compartments.

Chemically Fueled Systems Chemistry Across Length Scales

Advanced Functional Materials, EarlyView.
Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Suppression of amplitude dependent closest tune approach and its behavior under forced oscillations

Physical Review Accelerators and Beams, 2019
An amplitude dependent closest tune approach (ADeCTA) was first observed in the LHC in 2012. This potentially harmful effect can be generated by linear coupling in conjunction with octupoles.

Free oscillation oscillator with sinusoidal power characteristic

Bulletin of the National Technical University «KhPI» Series: Dynamics and Strength of Machines, 2017
Рассмотрены нелинейные колебания, вызванные или начальным отклонением осциллятора от положения равновесия или данной ему в этом положении начальной скоростью. Предполагается, что восстанавливающая сила пропорциональна синусу перемещения колебательной системы. Предусмотрено два варианта синуса: тригонометрический и гиперболический.

Mechanically Mutable Matrices: A Hierarchical Investigation of Decellularized Sea Cucumber Collagen as an Adaptable Scaffold Material

Advanced Functional Materials, EarlyView.
Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...

Exact closed forms for the transfer matrix of free oscillations in finite periodic Timoshenko–Ehrenfest beams

Results in Physics
In this work, we obtain closed-form expressions for the transfer matrix of free oscillations in finite periodic Timoshenko–Ehrenfest beams with an arbitrary number of cells.
