Abstract Li‐rich Mn‐based layered oxides (LRLO) are considered promising cathode candidates for high‐energy‐density lithium‐ion batteries (LIBs). However, severe capacity/voltage fading and poor rate performance hinder their practical application. Herein, a microstructure engineering strategy is put forward to design the unique bayberry‐like Li 1.2 Mn 0.54 Co 0.13 Ni O 2 (LRLO‐S) material, composed of spherical core shell self‐assembled by radially oriented nanorods with intrinsic rapid...

In this work, we propose artificial neural networks (ANNs) to predict the optical forces on particles with a radius of 50 nm and inverse-design subwavelength-grating (SWG) waveguides structure for trapping. The SWG are applied particle trapping due their superior bulk sensitivity surface sensitivity, as well longer working distance than conventional nanophotonic waveguides. To reduce time consumption design, train ANNs geometric waveguides, low mean square errors (MSE) achieve 2.8 × 10 −4 ....

The inverse design of metamaterials is the mapping spectral response (low dimensions) to structure (high dimensions). In process design, there will be a "one-to-many" problem (similar responses are generated by multiple meta-atoms), especially for designs with high degrees freedom (DOFs). Although traditional generative models (VAE, GAN) combined optimization algorithms can convert into forward prediction solve problem, this method requires iterative calculations and has low efficiency,...
