Effectiveness of self‐etching ceramic primer on the bond strength of dental glass ceramics: A systematic review and meta‐analysis of in vitro studies on feldspathic and leucite‐reinforced ceramics

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review and meta‐analysis evaluated the bond strength effectiveness of a self‐etching ceramic primer, specifically Monobond Etch & Prime (MEP), compared to hydrofluoric acid with silane (HF+S) in feldspathic and leucite‐reinforced dental glass‐ceramics (DGCs). Materials and Methods This study followed PRISMA‐p guidelines

Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.

Spatial Regulation of Silicon Accumulation in Peduncle Confers Sheathed Spike in Barley

Plant Biotechnology Journal, EarlyView.
ABSTRACT Peduncle, the uppermost internode in cereals, connects the stem to the inflorescence and is critical for the transport of water, nutrients and photosynthetic assimilates. While peduncle length associates with plant height and its elongation is primarily regulated by phytohormones, we report a previously unrecognized mechanism involving the ...

A Robust Cost‐Effective Spectrophotometric Method for Nb Determination in Refractory Nb‐doped Gadolinium Zirconate: Overcoming Matrix Dissolution Challenges

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT A simple, robust and cost‐effective analytical methodology was developed for the determination of niobium in highly refractory materials: Nb‐doped gadolinium zirconate (Gd2Zr2O7:Nb) and niobium pentoxide (Nb2O5). The challenge of digesting these matrices was successfully accomplished by establishing two independent dissolution procedures: (i ...
