Hysteretic and nonlinear dielectric behaviour in ferroelectric ceramics has been of interest since 1950s, when these materials found application in various electronic devices. Presently, these phenomena concern with important areas of science, technology a ...
We discuss the structural, electronic and dielectric properties of a model structure of the Si(100)-SiO2 interface that accounts for the amorphous nature of the oxide. After showing that the structural properties of this model are consistent with a variety ...
Responses to educational inequality in Ireland are typically individualistic, addressing themselves to the individual learner rather than to the structural or social processes that give rise to inequality. This chapter reviews some of the systemic causes o ...
Piezoelectric materials are used in a wide range of applications, with lead zirconate titanate (PZT) ceramics being the dominant family of materials, due to high piezoelectric coefficients, dielectric permittivity and coupling factors. The high properties ...
Mol. dynamics simulations (MDS) of the structural rearrangements on the pathway leading to procaspase 3 (I) activation are presented. A retrostructural approach was used to build I from mature caspase 3 (II). The peptide bond that was cleaved during enzyme ...
We suggest a control based method to uncover the structure (i.e., the dynamics of each system, the coupling direction, and coupling functions) of coupled systems. We show that driving a coupled system to steady states can reveal the underlying controlled c ...
The dielectric response of a ferroelectric film with bilinear coupling between order parameter and strain is theoretically addressed. An exact solution for the total (lattice and domain contributions) dielectric permittivity of the system for the case wher ...
We review the structural, electronic and dielectric properties of atomistic models of the Si(100)-SiO2 interface, which have been purposely designed in order to match a large variety of atomic-scale experimental data. After describing the generation proced ...
BaxSr1-xTiO3 (BST) and its composite films have been studied for the improvement of the tunable performances via nano-structual control. The strong correlation between strain and tunability similar to that between strain and permittivity was confirmed in t ...
Soluble oligomers are potent toxins in many neurodegenerative diseases, but little is known about the structure of soluble oligomers and their structure-toxicity relationship. Here we prepared on-pathway oligomers of the 140-residue protein alpha-synuclein ...
