The availability of clean water is fundamental for maintaining sustainable environments and human ecosystems. Capacitive deionization offers a cost-effective, environmentally friendly, and energy-efficient solution to meet the rising demand for clean water. Electrode materials based on pseudocapacitive adsorption have attracted significant attention in capacitive deionization due to their relatively high desalination capacity.

- The challenge of estimating dynamic functional connectivity (DFC) from resting-state fMRI data is addressed, leading to the development of a new model called HDP-HSMM-BPCA that improves upon existing methods.
- This model utilizes a hierarchical Dirichlet process to eliminate the limitations of traditional hidden Markov models, allowing for more accurate estimation of temporal dynamics and the automatic determination of the latent space's dimensionality.
- Experimental results show HDP-HSMM-BPCA performs better on synthetic data and highlights sparse DFC patterns in real fMRI data, advancing the understanding of brain connectivity.
Article Synopsis
- The brain's intrinsic dynamics involve spontaneous changes in neural activity, known as metastability, which relate to how different brain regions integrate and segregate functions.
- Compared to traditional methods, state-dependent effective connectivity better captures these dynamics by revealing causal relationships between brain areas, but tools to analyze this are limited.
- This study introduces a novel computational framework (NHSMM-MAR-sdNC) that adaptively infers brain states and their dynamics from data without rigid biological assumptions, promising advancements in studying brain connectivity and metastability using real-world fMRI data.
Ladder-Type Redox-Active Polymer Achieves Ultra-Stable and Fast Proton Storage in Aqueous Proton Batteries.
Angew Chem Int Ed Engl
October 2024
A ladder-type rigid-coplanar polymer with highly ordered molecular arrangement has been designed via a covalent cycloconjugation conformational strategy. Benefitting from the extended π-electron delocalization in the highly aromatic ladder-type polymeric backbone, the prepared polymer exhibits fast intra-chain charge transport along the polymeric chain, realizing extraordinary proton-storage capability in aqueous proton batteries.Affordable and safe aqueous proton batteries (APBs) with unique "Grotthuss mechanism," are very significant for advancing carbon neutrality initiatives.
