Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes
Advanced Functional Materials, EarlyView.Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.

Patching and Thickening Problems
Journal of Algebra, 1999 In this nicely written paper the authors develop the machinery of patching techniques in formal geometry which has been used to prove results on fundamental groups of algebraic curves. Among the results obtained we have the Abhyankar conjecture [\textit{M. Raynaud}, Invent. Math. 116, No. 1-3, 425-462 (1994; Zbl 0798.14013) and \textit{D.

Advanced Functional Materials, EarlyView.An atomically dispersed Ni catalyst featuring Ni‐N4 coordination is developed as a sulfur host for nonaqueous Zn─S batteries. This configuration modulates the electronic structure to lower activation barriers during rate‐limiting steps and promotes a robust ZnF2‐rich cathode‐electrolyte interphase, thereby accelerating sulfur redox kinetics ...

Thermoresponsive Soft and Self‐Anchoring Cuff Electrode for Chronic Peripheral Interfaces
Advanced Functional Materials, EarlyView.A novel thermoresponsive, soft and self‐anchoring (TSSA) cuff electrode utilizing shape memory polymers achieves autonomous, sutureless peripheral nerve fixation. Driven by thermally induced pre‐strain and tissue adhesion, the device self‐closes and softens at body temperature, successfully minimizing mechanical mismatch. This adaptive platform ensures

Advanced Functional Materials, EarlyView.This work developed an all‐aqueous freeze‐thaw strategy to create a dual‐conductive PVA/P3KBT binder for high volume‐change lithium–ion battery anodes. The resulting binder system strengthens the electrode structure, supports ion and electron transport, and accommodates repeated volume changes, reducing cracking and improving long‐term cycling ...

工程科学学报, 2017 To assure that compression on the rakes of a deep corn thickener does not stop mixing, an additional circular slurry system, which activates slurry all the time, is employed and running resistance is usually decreased. However, there is still uncertainty
