Advanced Science, EarlyView.An ultrafast (2‐minute), gas‐free chemical pre‐sodiation strategy using Na‐benzophenone is developed to compensate for initial sodium loss in calcium vanadate (CaV8O20). Driven by the Ca2+ ‘spectator effect’, the framework enables highly reversible, quasi‐zero‐strain solid‐solution sodium storage, explicitly bypassing destructive conversion reactions ...

Filtering of digital terrain models by 2D Singular Spectrum Analysis
, 2007 Singular Spectrum Analysis (SSA) has been approved as a model-free technique to analyse time series. SSA can solve different problems such as decomposition into a sum of trend, periodicities, and noise, smoothing, and others.

Advanced Science, EarlyView.A thermochemically engineered core–shell Si architecture is developed through the controlled evolution of a SWCNT‐coated Mg2Si precursor. The process simultaneously generates a nanoporous Si shell for strain accommodation and Li+ transport, a chemically anchored SiC interfacial layer for robust mechanical and electrical coupling, and a Mg‐containing Si

Batteries &Supercaps, Volume 8, Issue 3, March 2025.This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Analysis of the Hankel Matrix in Embedding Using the Singular Spectrum Analysis (SSA) Method
Indonesian Journal of Advanced ResearchSingular Spectrum Analysis (SSA) is an effective method of decomposition of time series for separating key components in data, such as trends, seasonality, and noise. This study aims to analyze the role of Hankel matrix in the SSA embedding process and how window length (L) selection can affect the effectiveness of component separation in data time ...
