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.

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

European Journal of Oral Sciences, Volume 134, Issue 5, October 2026.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Biobased Polyurethane Films Based on Andiroba (Carapa guianensis) and Buriti (Mauritia flexuosa) Oil Polyols

Journal of Applied Polymer Science, Volume 143, Issue 30, August 10, 2026.
Polyurethane films were prepared from andiroba (Carapa guianensis) and buriti (Mauritia flexuosa) oil‐derived polyols, emphasizing their potential as bio‐based materials. UV–Vis analysis indicates the retention of carotenoid‐related chromophoric features within the polymer matrix.

Antistatic High‐Density Polyethylene (HDPE)/Conductive Carbon Black (CCB) Composites for Automotive Parts: Influence of CCB Structure and Molding Technique

Journal of Applied Polymer Science, Volume 143, Issue 29, August 5, 2026.
Antistatic performance in HDPE/conductive carbon black composites is governed not only by filler structure but also by processing. Injection molding induces surface resistivity through skin–core effects, whereas compression molding favors conductive networks.
