LiNbO3 Coatings on NCM622: Structure and Performance Insights

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 17, September 8, 2025.
The amorphous structure of LiNbO3 coatings on LiNi0.6Co0.2Mn0.2O2 (NCM622) cathode active material is systematically investigated by scanning transmission electron microscopy. Theoretical simulations provide insight into the origin of structural transformations observed in the coating at lower calcination temperatures.

Engineering Intervertebral Disc Regeneration: Biomaterials, Cell Sources and Animal Models

open access: yesCell Proliferation, Volume 58, Issue 9, September 2025.
This review highlights the current tissue engineering approaches utilising biomaterials, animal models and cell sources for intervertebral disc regeneration and discusses future opportunities. ABSTRACT Intervertebral disc (IVD) degeneration is an age‐related problem triggering chronic spinal issues, such as low back pain and IVD herniation.

Time‐Series Factor Modeling and Selection

open access: yesJournal of Financial Research, Volume 48, Issue 2, Page 839-875, Summer 2025.
Abstract The article proposes a statistical time‐series factor model that incorporates deterministic orthogonal trend polynomials. Such polynomials allow capturing variation in returns without initially identifying a set of robust time‐series factors.
