High Performance Room Temperature Multiferroic Properties of w‐MnSe Altermagnet

open access: yesAdvanced Functional Materials, EarlyView.
Using first‐principles calculations, for the first time the Altermagneto‐Ferroelectric Coupling Effect (AFCE) is proposed, which enables control of both electric polarization and spin splitting in the band structure due to polyhedral rotations. This uncovers robust multiferroicity in wurtzite MnSe at room temperature, offering an exciting route for ...

Flux‐Regulated Crystallization of Perovskites Using Machine Learning‐Predicted Solvent Evaporation Rates for X‐Ray Detectors

open access: yesAdvanced Functional Materials, EarlyView.
By integrating machine learning into flux‐regulated crystallization (FRC), accurate prediction of solvent evaporation rates in real time, improving crystallization control and reducing crystal growth variability by over threefold, is achieved. This enhances the reproducibility and quality of perovskite single crystals, leading to reproducible ...

Struvite stones

open access: yesKidney International, 1978
Struvite, a crystalline substance first identified in the 18th century, is composed of magnesium ammonium phosphate (MgNH4PO4 · 6H2O). Ulex, a Swedish geologist, is generally credited with introduction of the term struvite in 1845; he coined the geological expression “struvite” in honor of H. C. G.

Formation of 2D Electron Gas at a Non‐Polar Perovskite Oxide Interface: SrHfO3/BaSnO3

open access: yesAdvanced Functional Materials, EarlyView.
Through experiments and Poisson‐Schrödinger simulations, 2D electron gas formed at the non‐polar SrHfO3/BaSnO3 interface is observed. A large conduction band offset enables modulation doping by the intrinsic deep donors in SrHfO3, resulting in carrier confinement in BaSnO3 without relying on interfacial polarization or termination‐layer engineering ...

Stone

open access: yes
  Inventor:    Travis Raymond-Charlie Stone Date:          4/30/25   A Stone is a logic-driven module that activates when a trigger occurs  such as a user action, event, signal, or condition. Alongside the trigger, it takes in context, such as current inputs, environment, memory state, or timing.

Topological Insulator Layered Bi2Te3 Based 3D‐Printed Nanocarbon Electrode for Rechargeable Aqueous Ammonium‐Ion Battery

open access: yesAdvanced Functional Materials, EarlyView.
In this work, Bi2Te3 is integrated into a 3D‐printed nanocarbon electrode for NH4+ storage. A rocking‐chair battery with CuHCF as the cathode delivers a high energy density of 134.8 Wh kg−1 and a power density of 1800 W kg−1. The design allows easy recovery of carbon additives, promoting sustainability and recyclability in next‐generation aqueous ...
