Synergistic Coupling of Host and Electrolyte Achieving 1270 Wh L−1 in Anode‐Free Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
A synergistic combination of a highly reversible host and a commercially viable carbonate‐rich electrolyte enables simultaneous stabilization of both anode and cathode interfaces in anode‐free lithium metal batteries. This integrated strategy delivers exceptional reversibility and a record volumetric energy density of 1270 Wh L−1 (including package) in

Stellar Pulsation and Evolution: A Combined Theoretical Renewal and Updated Models (SPECTRUM). I. Updating Radiative Opacities for Pulsation Models of Classical Cepheid and RR-Lyrae

open access: yesThe Astrophysical Journal
Pulsating stars are universally recognized as precise distance indicators and tracers of stellar populations. Their variability, combined with well-defined relationships between pulsation properties and intrinsic evolutionary parameters such as ...

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

open access: yesAdvanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Low Resistance Interphase Formation at the PEO‐LiTFSI|LGPS Interface in Lithium Solid‐State Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
Interfacial charge transfer and low‐resistance interphase formation between PEO‐based polymer and Li10GeP2S12 solid electrolytes are investigated using multi‐electrode impedance spectroscopy and advanced analytical techniques such as XPS and ToF‐SIMS.

Phase Diagrams Enable Solid‐State Battery Design

open access: yesAdvanced Materials Interfaces, EarlyView.
Batteries are non‐equilibrium devices with inherent thermodynamic driving forces to react at interfaces, regardless of kinetics or operating conditions. Chemical potential mismatches across interfaces are dissipated via interfacial reactions. In this work, it is illustrated how phase diagrams and chemical potential maps predict degradation pathways but

Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

Combinatorial Screening for Europium Induced Defect Engineering in Titania Anodic Memristors

open access: yesAdvanced Materials Interfaces, EarlyView.
A Ti‐Eu thin‐film combinatorial libary (3‐17 at.% Eu) was fabricated by co‐sputtering and anodisation. Systematic screening revealed forming‐free memristors with analog switching, with compositions between 7‐17 at.% Eu showing improved endurance and multilevel resistive states.

Numerical modelling of the RR Lyrae instability strip [PDF]

open access: yesCommunications in Asteroseismology, 2007
Selected results are presented of an extensive model survey of the radial pulsation of HB stars using a turbulent convective (TC) code. The main goal of the investigation was to systematically map the possible pulsational modes in the classical instability strip.
