Study of the Thermal and Hydrothermal Aging Effects on the Properties of 3D‐Printed Thermoplastic Polyurethane

Journal of Vinyl and Additive Technology, EarlyView.
Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

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

European Journal of Oral Sciences, EarlyView.
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).

Does treatment‐induced surface roughness of 3 mol% yttria‐stabilized tetragonal zirconia polycrystals influence the wear of opposing restorative materials? An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to investigate whether different surface treatments applied to 3 mol% yttria‐stabilized tetragonal zirconia polycrystals (3Y‐TZP), with comparable mean roughness (Ra) values, result in comparable values of additional surface roughness parameters, and to evaluate the influence of zirconia surface topography on vertical ...

Control Strategy of the Brake Dynamics for Railway Vehicles Equipped with Anti-Slip-Device [PDF]

, 2006
From the point of view of railway vehicle braking processes it is an important requirement to maintain the roll-ing-motion-state of the wheels, i.e. the macro-sliding-free rolling contact between the vehicle wheels and the rail-head, since in the course ...

Next Generation Smart Implant Surfaces: Engineering Multifunctional Antimicrobial, Immunomodulatory and Regenerative Interfaces

Journal of Periodontal Research, EarlyView.
Natural‐inspired nano‐textured implant surfaces can be functionalised to modulate macrophage polarisation and local immune responses. This bioactive control promotes improved tissue integration and healing outcomes. ABSTRACT Dental implants rely on a stable and functional interface between the implant surface, surrounding tissues, and the oral ...

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2233-2254, August 2026.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...
