Space charge and its impact on DC breakdown of polymeric materials

, 2013
The presence of space charge will lead to distortion of electric field distribution within the dielectric material, resulting electric field enhancement in certain region of the dielectric. The electric field enhancement could cause material degradation,

Rotating extremal black holes in Einstein-Born-Infeld theory

Journal of High Energy Physics
We construct exact solutions that describe the near horizon region of extremal rotating black holes in Einstein-Born-Infeld theory. Using generalized Komar integrals, we extract the electric charge and angular momentum from the near horizon geometries ...

Timelike bound orbits and pericenter precession around black hole with conformally coupled scalar hair

European Physical Journal C: Particles and Fields
We investigate the geodesic motions of timelike particles around a static hairy black hole with conformally coupled scalar field. We mainly focus on the effects of the scalar charge and electric charge on the marginally bound orbits (MBO), innermost ...

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

Advanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

A review of electric vehicle charge point map websites in the NSR: Interim report [PDF]

, 2013
This interim report is a review of the EV charge point (station) map websites in the North Sea Region (NSR) with the aim to identify if there are any patterns, or any noticeable gaps on the information presented by the interactive EV charge point tools ...

Thermodynamics with conformal Killing vector in the charged Vaidya metric

Journal of High Energy Physics
We investigate the charged Vaidya spacetime with conformal symmetry by classifying the horizons and finding its connection to Hawking temperature. We find a conformal Killing vector whose existence requires the mass and electric charge functions to be ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces
