Due to a lack of spatially resolved characterization studies on statistical and individual particle microstructure at multiple scales, a knowledge gap exists in understanding the mechanistic link between rapid performance failure and atomic-scale structure degradation in single-crystalline Ni-rich battery cathodes. In a recent publication in , Huang developed a multi-crystal rocking curve technique (combining X-ray and electron microscopy to capture both statistical and individual lattice distortions), which enables multiscale observations and further proves that the accumulation of the unrecoverable lattice rotation in cathodes upon repeated cycling exacerbates mechanical failure and electrochemical decay. The elucidation of failure mechanisms in single-crystalline cathodes offers valuable insights into the development of long-lasting and high-energy-density cathodes in next-generation batteries, encompassing strategies to mitigate lattice rotation and enhance lattice structure tolerance against lattice distortion within individual particles.

Non-ribosomal peptides (NRPs), polyketides (PKs), and NRP-PK hybrids are three classes of natural products that display a broad range of bioactivities, including antibiotic, antifungal, anticancer, and immunosuppressant activities. However, discovering these compounds through traditional bioactivity-guided techniques is costly and time-consuming, often resulting in the rediscovery of known molecules.

To address this challenge, there is an increasing focus on developing and evaluating new technologies to enhance the "design" and "test" phases of antibody-based drugs (e.g.

When seeking to release public use files for confidential data, statistical agencies can generate fully synthetic data. We propose an approach for making fully synthetic data from surveys collected with complex sampling designs. Our approach adheres to the general strategy proposed by Rubin (1993).
