Engineering Na‐Rich P2‐Type Layered Oxides Through Li/Ti Dual Doping for Oxygen Redox Activation and Superior Structural Stability

open access: yesAdvanced Energy Materials, EarlyView.
P2‐type sodium layered oxides have potential for high‐voltage operation but suffer from structural instability and capacity fading. This work demonstrates that synergistic Li and Ti co‐doping enhances sodium inventory, suppresses detrimental phase transitions, and activates reversible lattice oxygen redox.

Stabilizing Magnesium Anodes in Rechargeable Magnesium Batteries via Fluorinated Cyclic Ether Electrolyte Additive

open access: yesAdvanced Energy Materials, EarlyView.
A fluorinated cyclic ether, FDOL, is shown to stabilize Mg metal anodes by tuning Mg2+ solvation of the G2 electrolyte. The G2‐FDOL electrolyte suppresses passivation and thick, diffusion‐blocking Mg deposits, enabling more uniform Mg plating/stripping and sustained interfacial reactions.

Probing Einstein–Maxwell-scalar black hole via thin accretion disks and shadows with EHT observations of M87* and Sgr A*

open access: yesEuropean Physical Journal C: Particles and Fields
We investigated the shadows and thin accretion disks of Einstein–Maxwell-Scalar (EMS) black hole. Firstly, we investigated the influence of EMS parameters on the black hole shadow using the null geodesic method and constrained these parameters based on ...

Cosmic shear with Einstein rings

open access: yes
Cosmic shear is a key probe of modern cosmology. Amongst its challenges are shape noise and intrinsic alignments, both due to our ignorance of the unlensed shape of the source galaxies. I argue here that Einstein rings may be used as standard shapes to measure the external shear along their line of sight.

Why is an Einstein Ring Blue?

open access: yes, 2011
Albert Einstein predicted the existence of ‘Einstein rings’ as a consequence of his general theory of relativity. The phenomenon is a direct result of the idea that if a mass warps space-time then light (and other electromagnetic waves) will be ‘lensed’ by the strong gravitational field produced by a large cosmological body such as a galaxy. Since 1998,

What to Make and How to Make It: Combining Machine Learning and Statistical Learning to Design New Materials

open access: yesAdvanced Intelligent Discovery, EarlyView.
Combining machine learning and probabilistic statistical learning is a powerful way to discover and design new materials. A variety of machine learning approaches can be used to identify promising candidates for target applications, and causal inference can help identify potential ways to make them a reality.

Why Physics Still Matters: Improving Machine Learning Prediction of Material Properties With Phonon‐Informed Datasets

open access: yesAdvanced Intelligent Discovery, EarlyView.
Phonons‐informed machine‐learning predictive models are propitious for reproducing thermal effects in computational materials science studies. Machine learning (ML) methods have become powerful tools for predicting material properties with near first‐principles accuracy and vastly reduced computational cost.
