Effect of primer composition on zirconia surface properties and bond strength
Abstract This study investigated the effects of different surface treatments on surface roughness, wettability, and shear bond strength of 3Y‐TZP (yttria‐stabilized tetragonal zirconia polycrystal). A total of 180 specimens (6 × 6 × 2 mm) underwent sandblasting with 50 µm Al2O3 and were divided into six groups: (i) control (no treatment), (ii) 10‐MDP +

Evaluation of the Influence of Antifoam Formulations on Asphaltene Aggregates Using AFM and SEM‐EDS
ABSTRACT Asphaltenes, naturally occurring surfactants in crude oil play a pivotal role in stabilizing oily foams during primary oil processing. Accordingly, understanding how antifoam formulations influence asphaltene aggregation is essential. This study investigates the effect of polydimethylsiloxane (PDMS) with varying molar masses on asphaltene ...
