Abstract

Abstract An asymmetric a-side alkyl chain anthracene derivative 6-(4 (-2 Ethyl Octyl) Phenyl) 2Phenyl Anthracene (EOPPA) was designed based on a π-electron skeleton with a side alkyl chain of anthracene core molecule. EOPPA was found to be a sturdy and high-performance p-type semiconductor for optoelectronic applications. The creation has successfully made this new material EOPPA with the best solubility, which exhibits both sufficient solvent solubility and thermal stability. The asymmetrical structural features of EOPPA allowed for the preparation of two-dimensional crystalline thin films in micrometer sizes with 100 nm thicknesses on a Si/SiO2 substrate through a solution processing method. The efficient solution processing synthesis of EOPPA and its high performance suggest that it has great potential in the field of organic electronics. The EOPPA demonstrated optoelectronic properties, crystalline structure, and good thin-film transistors having mobilities higher than 0.18 cm2 V−1 S−1, and a high current on/off ratio that can withstand temperatures of almost 225 °C. Furthermore, EOPPA presents good potential to be amongst the next generation of p-type anthracene core organic semiconductors, especially for practical printed electronics applications.

14. From the Landau-de Gennes theory to the Ericksen-Leslie theory in dimension two

Author

Subjects
Mathematics - Analysis of PDEs
Abstract

In this paper, we study the connection between the Ericksen-Leslie equations and the Beris-Edwards equations in dimension two. It is shown that the weak solutions to the Beris-Edwards equations converge to the one to the Ericksen-Leslie equations as the elastic coefficient tends to zero. Moreover, the limiting weak solutions to the Ericksen-Leslie equations may have singular points.

48. Liouville theorem for steady-state solutions of simplified Ericksen-Leslie system

Author

Hao, Yihang, Liu, Xiangao, and Zhang, Xiaotao

Subjects
Mathematics - Analysis of PDEs
Abstract

In this paper, we investigate the steady simplified Ericksen-Leslie system. For three dimension, we obtain Liouville theorems if $u$ and $\nabla d$ satisfy the Galdi's[1] condition, or some decay conditions. Note that the simplified Ericksen-Leslie system becomes Navier-Stokes equations when $d$ is constant vector.

49. Partial regularity of suitable weak solutions of the Navier-Stokes-Planck-Nernst-Poisson equation

Subjects
Mathematics - Analysis of PDEs
Abstract

In this paper, inspired by the seminal work by Caffarelli-Kohn-Nirenberg \cite{CKN} on the incompressible Navier-Stokes equation, we establish the existence of a suitable weak solution to the Navier-Stokes-Planck-Nernst-Poisson equation in dimension three, which is shown to be smooth away from a closed set whose $1$-dimensional parabolic Hausdorff measure is zero., Comment: 31 pages. A few mistakes have been fixed

50. Local well-posedness of isentropic compressible Navier-Stokes equations with vacuum

Author

Subjects
Mathematics - Analysis of PDEs
Abstract

In this paper, the local well-posedness of strong solutions to the Cauchy problem of the isentropic compressible Navier-Stokes equations is proved with the initial date being allowed to have vacuum. The main contribution of this paper is that the well-posedness is established without assuming any compatibility condition on the initial data, which was widely used before in many literatures concerning the well-posedness of compressible Navier-Stokes equations in the presence of vacuum.
