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 ...

The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

Journal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

From fossil to bio‐circular plastics: the environmental benefits of bio‐attributed acrylonitrile butadiene styrene in single‐use cystoscopes

BJU International, EarlyView.
Background Single‐use cystoscopes are increasingly adopted in urology, but concerns regarding their environmental footprint persist. Substituting conventional fossil‐based plastics with bio‐attributed materials may reduce life cycle impacts, yet the magnitude and robustness of this benefit remain uncertain.

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and

Chemical Exposures, DNA Methylation and Whole Blood DNA Damage in Pet Golden Retrievers

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Canine multicentric lymphoma (CL) is a common and typically fatal cancer among dogs. Although certain breeds have a higher incidence of CL, its environmental risk factors remain uncertain. Exposures to herbicides and volatile organic compounds (VOCs) associate with non‐Hodgkin lymphoma in people.
