Stereolithography three-dimensional (3D) printing technology enables the customization of ceramic-based solid electrolyte structures with desired electrochemical properties; however, formulating slurries that both are highly ceramic-loaded and have low viscosity for printing poses a challenge. Here, we propose an ionogel-coated ceramic approach to prepare a shear-thinning fast-ion conductor ceramic (LiLaZrTaO) slurry, which possesses both a high ceramic content of 50 wt % and a low viscosity of 1.53 Pa·s.

Deoxyribonucleic acid (DNA) serves as a repository of genetic information in cells and is a critical molecular target for various antibiotics and anticancer drugs. A profound understanding of small molecule interaction with DNA is crucial for the rational design of DNA-targeted therapies. While the molecular mechanics/Poisson-Boltzmann surface area (MM/PBSA) and molecular mechanics/generalized Born surface area (MM/GBSA) approaches have been well established for predicting protein-ligand binding, their application to DNA-ligand interactions has been less explored.

In this work, the regulation of liquid self-transport is achieved through architectural and thermal coupling, transitioning from free surfaces to open channels. Hierarchical structures inspired by the skin of a Texas horned lizard are designed, with the primary structure of wedged grooves and the secondary structure of capillary crura. This design enables advantages including long-distance self-transport, liquid storage and active reflux management on free surfaces, directional transportation, synthesis and detection of reagents in confined spaces, as well as controllable motion and enhanced heat dissipation in open channels.

All-solid-state polymer electrolytes are promising for lithium batteries, but Li+ transport in these electrolytes relies on amorphous chain segment movement, leading to low Li+ mobility and poor mechanical strength. Here we propose a novel Li+ transport mechanism mediated by PEO3:LiBF4 nanocrystals (NCPB) with the aggregate (AGG) anionic structure, which enables a change from amorphous to crystalline phase dominated ion transport in all-solid-state PEO/LiBF4 electrolyte. Experiments and simulations reveal that the interaction between Li+ and F in NCPB with AGG anionic structure simultaneously restricts anion transport and reorients anions within the free volume of NCPB, resulting in a three-coordination intermediate to facilitate Li+ transport.
