Skyrmion model of nano-domain nucleation in ferroelectrics and ferromagnets [PDF]
A skyrmion model of nano-domain ejection from large domain walls in ferroelectrics is presented, together with data on lead germanate Pb5Ge3O11 and comparison data on ferromagnetic iron garnet.

Skyrmion domain wall collision and domain wall-gated skyrmion logic [PDF]
Physical Review B, 2016 Skyrmions and domain walls are significant spin textures of great technological relevance to magnetic memory and logic applications, where they can be used as carriers of information. The unique topology of skyrmions makes them display emergent dynamical properties as compared with domain walls. Some studies have demonstrated that the two topologically

Hybrid functional study on the ferroelectricity of domain walls with O-vacancies in PbTiO3
Mechanical Engineering Journal, 2015 Nonlinear defect interactions between the 180° domain wall and oxygen-vacancies (O-vacancies) in PbTiO3, and the characteristic ferroelectricity due to the interactions are investigated using first-principles calculations based on the hybrid Hartree-Fock

Magnetic domain-wall tilting due to domain-wall speed asymmetry [PDF]
Physical Review B, 2018 Chiral magnetic materials provide a number of challenging issues such as the highly efficient domain wall (DW) and skyrmion motions driven by electric current, as of the operation principles of emerging spintronic devices. The DWs in the chiral materials exhibit asymmetric DW speed variation under application of in plane magnetic field.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Domain Wall Dynamics in Amorphous Microwires [PDF]
, 2008 Here we present the domain wall dynamics in FeNi-based microwires with positive magnetostriction. Two different ranges were found which differs by the measured domain wall mobility.

Skyrmion Pair Racetrack Utilizing Hall Motion
MagnetochemistryThe skyrmion racetrack is a promising concept for future information technology. The primary issues with skyrmion racetrack memory are now error codes and Hall motion. Here, we propose a skyrmion pair racetrack memory. The Oersted fields generated by the

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

New Journal of Physics, 2019 We present a study of the magnetic configuration due to step-induced magnetic frustration at ferromagnetic/antiferromagnetic (FM/AFM) interfaces. At a substrate monatomic step edge, a 180° domain wall emerges.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
