Evaluation of Electrical Performance and Life Estimation of PPs for HVDC Power Cable

Energies, 2021
Demand and need for the application of high voltage direct current (HVDC) are increasing because of high capacity and long-distance transmission. Research on polypropylene (PP) that can increase the operation temperature compared to existing insulation ...

Formation of 2D Electron Gas at a Non‐Polar Perovskite Oxide Interface: SrHfO3/BaSnO3

Advanced Functional Materials, EarlyView.
Through experiments and Poisson‐Schrödinger simulations, 2D electron gas formed at the non‐polar SrHfO3/BaSnO3 interface is observed. A large conduction band offset enables modulation doping by the intrinsic deep donors in SrHfO3, resulting in carrier confinement in BaSnO3 without relying on interfacial polarization or termination‐layer engineering ...

Suppression of magnetic vortex losses in submicron NbN coplanar waveguide resonators

Scientific Reports
We present a method for improving the performance of microwave coplanar resonators in magnetic fields, by using narrow superconducting strips of width close to the London penetration depth. In a range of low fields, the narrow strips inhibit the presence

Possible transport evidence for three-dimensional topological superconductivity in doped β-PdBi2

Scientific Reports, 2019
Interest in topological states of matter burgeoned over a decade ago with the theoretical prediction and experimental detection of topological insulators, especially in bulk three-dimensional insulators that can be tuned out of it by doping.

Extreme magnetic field-boosted superconductivity

, 2019
Applied magnetic fields underlie exotic quantum states, such as the fractional quantum Hall effect and Bose-Einstein condensation of spin excitations. Superconductivity, on the other hand, is inherently antagonistic towards magnetic fields.

Optimizing (1‐x) BiFeO3‐xCaTiO3 Perovskites: A Pathway to Efficient Flexible Energy Storage

Advanced Functional Materials, EarlyView.
Perovskite materials, like BFO CTO, are popular due to their high conductivity, low cost, and wide availability. In this work a symmetric electrochemical cell based on BFO‐CTO shows a charge of 3.356 C.cm⁻2, giving a specific capacitance of 2.79 mF.cm⁻2 at 1 mV.s⁻2.

Bimetallic Nanoparticles: Enhanced Magnetic and Optical Properties for Emerging Biological Applications

Applied Sciences, 2018
Metal nanoparticles are extensively studied due to their unique chemical and physical properties, which differ from the properties of their respective bulk materials. Likewise, the properties of heterogeneous bimetallic structures are far more attractive

Crystal orientation and thickness dependence of superconductivity on tetragonal FeSe1-x thin films

, 2009
Superconductivity was recently found in the simple tetragonal FeSe structure. Recent studies suggest that FeSe is unconventional, with the symmetry of the superconducting pairing state still under debate.

Emergence of Local Magnetic Moment in Ternary TaWSe2 Single Crystal via Atomic Clustering

Advanced Functional Materials, EarlyView.
This study investigates local magnetic moments in ternary TaWSe2. Triangular Ta clusters with consistent shapes are identified through STM/S, and DFT calculations. These clusters induce localized strain, generating magnetic moments at the cluster corners. Magnetic measurements confirm a magnetic anomaly at ∼50 K.
