Anisotropic spin-flip-induced multiferroic behavior in kagome Cu3Bi(SeO3)(2)O2Cl

Compared to the previous report on Cu3Bi(SeO3)(2)O2X (X = Cl, Br) [V. Gnezdilov et al., (arXiv: 1604.04249)], where no dielectric anomaly was observed without magnetic field near T-N similar to 25.6K, we further present the dielectric behaviors without and ...

Scaling description of non-local rheology

Matthieu Wyart, Jie Lin

The plastic flow of amorphous materials displays non-local effects, characterized by a cooperativity length scale xi. We argue that these effects enter in the more general description of surface phenomena near critical points. Using this approach, we obtai ...

Anisotropic pressure effects on the Kagome Cu3Bi(SeO3)(2)O2Cl metamagnet

Helmuth Berger

The anisotropic spin-flip-induced multiferroic property of the Kagome single-crystal Cu3Bi(SeO3)(2)O2Cl was recently investigated. The doping effects on the structural and magnetic properties of Cu3Bi(Se1-xTexO3)(2)O2Cl (0

Fabrication of 2D Material Based NEMS Resonators

Tom Larsen, An Tran

2D materials such as graphene, MoS2 and phosphorene are promising candidates for resonating mechanical sensors due to excellent tunable electrical/- mechanical properties, low masses, and maximal surface to volume ratios. Mechanical resonators based on sup ...

Criteria for the existence of a potential well

Charles Stuart

We consider a critical point u(0) of a functional f is an element of C-1 (H, R), where H is a real Hilbert space, and formulate criteria ensuring that u(0) lies in a potential well of f without supposing that f' is Frechet differentiable at u(0). The deriv ...

Thermochromic coatings for overheating protection of solar thermal collectors - novel type of doping (TARGET95)

Andreas Schueler, Anna Krammer

Overheating and the resulting stagnation of solar thermal collectors is a common problem even in central European latitudes. During stagnation, high temperatures lead to water evaporation, glycol degradation and stresses in the collector with increasing va ...

Redefining solubility parameters: Bulk and surface properties from unified molecular descriptors

Vassily Hatzimanikatis

The central objective of this work is to revisit the development of the widely used solubility parameters and linear solvation energy relationships (LSER) and seek interconnections and possibilities for secure exchange of information. Partial solvation par ...

Group Decisions Influence Emergence and Regulation of Leaders during Collective Migration of Epithelial Cells

Medhavi Vishwakarma

Collective migration is a central event involving coordinated movement of several individuals. One of the critical events during collective migration is the emergence of leading individuals, who provide directional guidance for the group movement. While on ...

Evolution of 3-D Transport Pathways and Triple-Phase Boundaries in the Ni-YSZ Hydrogen Electrode upon Fuel Cell or Electrolysis Cell Operation

Jan Van Herle, Marco Cantoni, Arata Nakajo, Pierre Burdet

The degradation of the Ni-YSZ electrode was investigated after SOFC or SOEC operation for up to 4,700 h and 10,700 h, respectively. 3-D FIB-SEM serial sectioning combined with 3-D EDS elemental mapping allowed the measurement of structural, material and el ...
