Nucleation‐Controlled Reconstruction of CuOx for Selective CO2 Electroreduction

Advanced Functional Materials, EarlyView.
The ratio of oxygen vacancies (Ov) and exposed Cu2O (111)/(200) of CuOx precatalyst is modulated by nucleation control of Cu(OH)2 precursor. Low Ov ratio and high ratio of Cu2O (111)/(200) in slow‐nucleated CuOx reconstructs to high‐coordinated oxide‐derived copper (OD‐Cu) during electrochemical CO2 reduction reaction (CO2RR) and exhibits enhanced ...

Computing Comprehensive Grobner Systems: A Comparison of Two Methods [PDF]

Computer Science Journal of Moldova, 2017
In this paper, we consider two main approaches to compute Gr\"obner bases for parametric polynomial ideals, namely the {\sc DisPGB} algorithm developed by Montes \cite{monts1} and the {\sc PGBMain} proposed by Kapur, Sun and Wang \cite{kapur}.

A Sum-of-Squares Approach to the Analysis of Zeno Stability in Polynomial Hybrid Systems

, 2013
Hybrid dynamical systems can exhibit many unique phenomena, such as Zeno behavior. Zeno behavior is the occurrence of infinite discrete transitions in finite time.

Feng's first-integral method to traveling wave solutions of the Ostrovsky system

Electronic Journal of Differential Equations, 2019
In this paper, we apply Feng's first-integral method to study traveling wave solutions to a two-component generalization of the Ostrovsky system. We convert the two-component generalization of the Ostrovsky system to an equivalent autonomous system ...

Path Planning of Free-Floating Robot in Cartesian Space Using Direct Kinematics

International Journal of Advanced Robotic Systems, 2007
Dynamic singularities make it difficult to plan the Cartesian path of free-floating robot. In order to avoid its effect, the direct kinematic equations are used for path planning in the paper.

MXene/PEDOT Functional Coatings on Flexible Microelectrode Arrays for Multianalyte In Vivo Neurochemical Sensing and Electrophysiology

Advanced Functional Materials, EarlyView.
A MXene/PEDOT coating enables multimodal functionality and dual‐analyte detection of dopamine and serotonin in flexible microelectrode arrays while enhancing electrophysiological recording quality. The anti‐fouling, low‐impedance interface overcomes key limitations of conventional coatings, providing a robust and versatile platform to investigate the ...

Resultant Tools for Parametric Polynomial Systems with Application to Population Models

, 2022
We are concerned with the problem of decomposing the parameter space of a parametric system of polynomial equations, and possibly some polynomial inequality constraints, with respect to the number of real solutions that the system attains. Previous studies apply a two step approach to this problem, where first the discriminant variety of the system is ...
