arXiv paper proposes property-registry contract for lattice design search

A new arXiv preprint describes a contract mechanism for searching thermal-mechanical lattice libraries that lets a design system retrieve a matching cell or explicitly refuse when no candidate meets the requirements. The work targets early-stage engineering queries, which are knowledge-heavy and frequently jointly unsatisfiable, such as demands for a cell that is simultaneously light, stiff, thermally conductive and inexpensive. The proposed property-registry approach is framed as a way to make refusal a legitimate outcome rather than returning an unsuitable match.

Density-Matrix Framework Aims to Speed Electronic-Structure Analysis of Battery Electrolytes

Researchers propose a density-matrix-based approach for analyzing the electronic structure of electrolytes used in lithium batteries. The method targets the link between molecular functional groups, lithium-ion solvation, and salt-anion behavior, which conventional quantum chemistry handles too slowly for broad screening. The goal is to make systematic comparison of many electrolyte formulations computationally practical.
