Energy Landscapes in Chemical Reactions and Transport

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Microscopic parametrizations for gate set tomography under coloured noise

npj Quantum Information
Gate set tomography (GST) allows for a self-consistent characterization of noisy quantum information processors (QIPs). The standard approach treats QIPs as black boxes only constrained by the laws of physics, attaining full generality at a considerable ...

Redox‐Mediating Mo2C Nanoparticles Confined Within Nitrogen‐ and Phosphorus‐Codoped Amorphous Carbon Matrix for Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional interlayer composed of Mo2C nanoparticles embedded in a nitrogen‐ and phosphorus‐doped amorphous carbon matrix on graphene is developed via electrostatic self‐assembly and thermal transformation. The resulting architecture suppresses the shuttle effect, improves electrical conductivity, and facilitates redox conversion kinetics ...

Investigating Dark Energy Equation of State With High Redshift Hubble Diagram

Frontiers in Astronomy and Space Sciences, 2020
Several independent cosmological data, collected within the last 20 years, revealed the accelerated expansion rate of the Universe, usually assumed to be driven by the so called dark energy, which, according to recent estimates, provides now about 70% of

Fluorination Engineering for Stable Interfacial Chemistry in Deep Eutectic Amide‐Based Electrolytes Enables High‐Performance LiNi0.8Co0.1Mn0.1O2/Li Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The fluoroamide‐based deep eutectic electrolyte with fluoroethylene carbonate efficiently enhances the safety performance of Ni‐rich ternary lithium metal batteries. Fluoroethylene carbonate undergoes preferential reaction at the electrode surface, forming a LiF‐rich interphase layer that contributes to enhanced long‐term cycling performance of the ...

Connecting mean-field theory with dynamo simulations

Living Reviews in Solar Physics
Mean-field dynamo theory, describing the evolution of large-scale magnetic fields, has been the mainstay of theoretical interpretation of magnetism in astrophysical objects such as the Sun for several decades.

Stable calcium metal batteries enabled by ionic covalent organic framework artificial protection layers

InfoMat, EarlyView.
Irreversible calcium (Ca) plating and stripping pose significant challenges for Ca metal batteries due to the formation of an ion‐insulating passivation layer. This study demonstrates that ionic covalent organic frameworks (iCOFs) serve as effective artificial protective layers for Ca metal anodes, facilitating rapid Ca2+ transport and promoting ...

Reinforcement Learning Enabled Nanophotonic Devices

Laser &Photonics Reviews, EarlyView.
A reinforcement learning algorithm is used to design photonic devices. The method creates metagratings and grating couplers that efficiently control both the direction and polarization of light. Further, a reinforcement learning approach is used to design in‐plane integrated photonic devices. This approach paves the way for advanced photonic components
