Mechanistic Insights into the Surface Instabilities of TiNb2O7, a High‐Power Li‐Ion Anode

open access: yesAdvanced Materials Interfaces, EarlyView.
TiNb2O7 is an attractive anode for Li‐ion batteries, particularly when safety is of the highest concern. However, despite operating at high potentials, electrolyte degradation is a major concern. It is demonstrated that throughout the entire charge‐discharge cycle a number of surface reactions occur which both produce gas and result in Ti dissolution ...

Emergent Ferromagnetism at LaFeO3/SrTiO3 Interface Arising from a Strain‐Induced Spin‐State Transition

open access: yesAdvanced Materials Interfaces, EarlyView.
Strain at the LaFeO3/SrTiO3 interface induces spin‐state disproportionation, creating a checkerboard pattern of low‐ and high‐spin Fe3+ ions. This unusual configuration leads to interfacial ferromagnetism in an otherwise antiferromagnetic insulator. Using electron microscopy, spectroscopy, and density functional theory, this work reveals a new route to

Low‐Noise, Unbiased Ferromagnetic‐Resonance‐Driven Thin‐Film Integrated Giant Magnetoimpedance Sensors

open access: yesAdvanced Materials Technologies, EarlyView.
Utilizing a novel (Ni81Fe19/Ti)4/Cu/(Ni81Fe19/Ti)4 thin‐film multilayer with low coercive field, low damping and a superior GMI ratio, a compact, low‐noise unbiased FMR‐driven integrated GMI sensor with a superior magnetic noise performance of ≈100 pT/√Hz is first demonstrated, owing to reduced phase noise from well‐defined aligned magnetic domains and

The Impact of DNA as a Chemical Admixture for Cementitious Materials

open access: yesAdvanced Materials Technologies, EarlyView.
DNA molecules are added to cement pastes and their effects on rheology and hydration time are studied. DNA's chemical structure is composed of polysaccharide and phosphate groups, which are active functional groups in different commercial chemical admixtures: Viscosity modifiers and superplasticizers.
