Design of Sodium Chalcohalide Solid Electrolytes with Mixed Anions for All‐Solid‐State Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A novel family of sodium hafnium chalcohalide SSEs is designed with dual‐anion frameworks. Compared to the halide SSEs, the mixed anion chalcohalide framework exhibits a more compact morphology, improved thermal and mechanical properties, and enhanced electrochemical performance with different cathode materials.

Asymptotic enumeration of magic series [PDF]

open access: yes, 2013
A magic series is a set of natural numbers that, by virtue of its size, sum, and maximum value, could fill a row of a normal magic square. In this paper, we derive an exact two-dimensional integral representation for the number of magic series of order N.

Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals

open access: yesAdvanced Functional Materials, EarlyView.
Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.

Tunable and Recyclable Piezoelectric Biomaterials via Ion‐Directed Guanine‐Quadruplex Assembly

open access: yesAdvanced Functional Materials, EarlyView.
Guanine‐quadruplex (GQ) assemblies, formed via ion‐mediated self‐assembly of amphiphilic guanine derivatives, are introduced as tunable and recyclable piezoelectric biomaterials. Distinct alkali ions induce unique dipole configurations and piezoelectric outputs, with K⁺ yielding the highest performance.
