Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

open access: yesAdvanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

High‐Throughput Screening and Characterization of Non‐Flammable Na‐Cl Solid Electrolytes

open access: yesAdvanced Electronic Materials, EarlyView.
A Na‐Cl solid electrolyte with high ionic conductivity is screened from a structural database using force‐field molecular dynamics (MD) simulations and density functional theory (DFT)‐MD calculations. Na3La5Cl18 is identified, synthesized, and characterized.

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

Testing the Marketing Performance of German Wheat Farmers

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper analyses the marketing performance of wheat farmers in Germany. Wheat sales data from 465 individual farms over a 12‐year period are used to test against different market benchmarks. Market benchmarks are constructed by simulating passive trading agents using regional wheat prices.

Laparoscopic and Endoscopic Cooperative Surgery for Gastric Cancer as an Alternative Treatment in Elderly Patients: A Prospective Observational Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
In a prospective study of 20 elderly gastric cancer patients who declined gastrectomy, laparoscopic and endoscopic cooperative surgery (LECS) was technically safe and preserved postoperative function. However, as oncological curability cannot be assured in advanced cases, careful selection and informed consent are essential.
