Artificial intelligence–driven decoupling structure–activity relationship for lithium‐ion batteries

InfoScience, EarlyView.
Artificial intelligence can efferently accelerate the high‐throughput screening of battery materials, the analysis of multiphase mechanisms, and the precise prediction of capacity and cycle life. This review systematically summarizes the applications of machine learning (ML) in decoupling the complex structure‐activity relationships of lithium‐ion ...

Designing chiral organic small molecules for circularly polarized light detection via group theory

InfoMat, EarlyView.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...

Large-N correlator systems for low frequency radio astronomy

, 2013
Low frequency radio astronomy has entered a second golden age driven by the development of a new class of large-N interferometric arrays. The low frequency array (LOFAR) and a number of redshifted HI Epoch of Reionization (EoR) arrays are currently ...

Octave‐Spanning, Deterministic Single Soliton Generation in 4H‐Silicon Carbide‐On‐Insulator Microring Resonators

Laser &Photonics Reviews, EarlyView.
The miniaturization of metrology and precision spectroscopy systems requires robust, turn‐key microcombs with broad bandwidth, low threshold, and high efficiency. Here, high‐Q, dispersion‐engineered microresonators in a high‐confinement nonlinear SiC platform, combined with waveguide‐enabled thermal management and laser cooling, enable deterministic ...
