Surface properties and biofilm formation of a manufacturer‐reinforced, nanographene‐modified pre‐polymerized CAD‐CAM polymethylmethacrylate denture base material: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the surface roughness, hydrophobicity, and Candida albicans biofilm formation of three denture base materials, including two computer‐aided design and computer‐aided manufacturing (CAD‐CAM) polymethylmethacrylate (PMMA) resins and one conventional heat‐polymerized PMMA, before and after thermocycling (TC).

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.

3D assessment of the marginal and internal gap and fracture load of ceramic surveyed inlays designed for removable partial denture support: An in vitro comparative study

Journal of Prosthodontics, EarlyView.
Abstract Purpose To assess the internal and marginal gaps and the fracture load of different machinable ceramics for an inlay acting as a support for a removable partial denture. Materials and Methods Sixty extracted human teeth (first maxillary premolar) were collected (n = 10 for each group).

Clinical Outcomes of Rubber‐clip‐assisted Versus Conventional Colorectal Endoscopic Submucosal Dissection: A Retrospective Study

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Adequate traction is essential for safe and efficient colorectal endoscopic submucosal dissection (ESD), but gravitational traction is often insufficient in certain situations. Several traction techniques are reportedly effective.

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 3796-3817, December 2026.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Influence of the Boundary Conditions on the Seismic Response of Existing Masonry Infills From In‐Plane and Dynamic Out‐of‐Plane Tests

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 3880-3904, December 2026.
ABSTRACT Despite increasing attention to the seismic performance of masonry infills, their out‐of‐plane dynamic behaviour remains insufficiently explored, particularly under pre‐existing in‐plane damage. This study presents a comprehensive experimental campaign designed to investigate the seismic behaviour of an existing weak masonry infill typology ...

Enhancing the Seismic Resilience of Masonry‐Infilled RC Structures Using Rubber Joints: Full‐Scale 3D Shaking Table Tests

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 15, Page 4088-4112, December 2026.
ABSTRACT Masonry infills in reinforced concrete (RC) frames are highly vulnerable to seismic damage, often sustaining severe cracking even under moderate ground motion, which in turn leads to considerable economic losses and safety risks. To address this issue, this study experimentally evaluates the effectiveness of two innovative rubber‐based joints ...

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, Volume 1, Issue 4, December 2026.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.
