Preservation of Dental Structure in Prosthetic Restorations: Vertical and Horizontal Preparation Techniques. Systematic Review

Clinical and Experimental Dental Research, Volume 12, Issue 2, April 2026.
ABSTRACT Objectives Crown preparation leads to irreversible dental tissue loss, which affects long‐term restoration success. The advantages of horizontal (chamfer) versus vertical preparation techniques (BOPT, BOPTm) remain debated. This systematic review evaluates which method is most conservative regarding dental structure removal and examines their ...

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Multi‐Dimensional Characterization of Sodium‐Ion Battery Materials: Bridging Atomic Structure, Interface Chemistry and Electrochemical Performance

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Sodium‐ion batteries (SIBs) have emerged as promising candidates for large‐scale energy storage due to their cost‐effectiveness and resource abundance. However, challenges such as sluggish ion diffusion kinetics, structural degradation, and interfacial instability hinder their practical applications.

Alumina–Zirconia Composite Filaments for 3D‐Printed Scaffolds With Bioglass Infiltration for Medical Applications

International Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
This study demonstrates the innovative development of alumina–zirconia composite scaffolds produced by fused filament fabrication (FFF) and infiltrated with bioglass via the sol–gel method. The combination yielded highly porous three‐dimensional architectures (500 µm–1 mm), suitable for nutrient diffusion, vascularization, and cell colonization.
