Different low-cost materials to prevent the alteration induced by formic acid on unstable glasses

open access: yesHeritage Science, 2021
The most frequent cause of glass degradation is environmental moisture, which is adsorbed on its surface forming a hydration layer that induces the rupture of the glass network.

Crystallization Process and Site-Selective Excitation of Nd3+ in LaF3/NaLaF4 Sol–Gel-Synthesized Transparent Glass-Ceramics

open access: yesCrystals, 2021
In this study, transparent oxyfluoride glass-ceramics (GCs) with NaLaF4 nanocrystals (NCs) were prepared by the sol–gel method for the first time. Three different molar ratios of La(CH3COO)3/Na(CH3COO) were used to obtain the GCs, which were sintered at ...

Electrochemical Performance of Nitrogen‐Doped Carbons: From Fundamental Studies to Practical Pouch Device

open access: yesBattery Energy, Volume 5, Issue 1, January 2026.
ABSTRACT Nitrogen‐doped carbide‐derived carbons (N‐CDCs) are promising materials for energy storage due to their tunable structure and chemistry. Here, we design a molecular architecture strategy to promote nitrogen incorporation and microstructural control during the synthesis of N‐CDCs.

Er3+–Yb3+‐codoped LaF3 glass–ceramic optical fiber

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 1, January 2026.
Abstract This paper reports the preparation and characterization of LaF3‐based glass–ceramic (GC) optical fibers codoped with Er3+ and Yb3+ ions, using the rod‐in‐tube method with Duran glass as cladding. Structural analysis, including x‐ray diffraction and transmission electron microscopy, confirmed the presence of LaF3 nanocrystals in the core, with ...
