Impact Absorption Power of Polyolefin Fused Filament Fabrication 3D‐Printed Sports Mouthguards: In Vitro Study

open access: yesDental Traumatology, Volume 41, Issue 2, Page 213-223, April 2025.
ABSTRACT Background/Aim This study aims to evaluate and compare the impact absorption capacities of thermoformed ethylene vinyl acetate (EVA) mouthguards and 3D‐printed polyolefin mouthguards used in sports dentistry applications. The objective is to determine whether 3D‐printed polyolefin mouthguards offer superior impact toughness compared to ...

Honeybees directly outcompete other flower visitors through interference competition on shared resource

open access: yesEcological Entomology, EarlyView.
The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...

High Strength Steel Fatigue Crack Growth Database for Offshore Renewable Energy Applications

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT High strength steels can reduce costs and carbon emissions in offshore renewable energy, but their effect on structural integrity remains unclear. In welded structures, such as support structures for offshore wind and tidal turbines, fatigue life is dominated by crack growth from flaws at weld toes.

Influence of Temperature Dependent Properties on Tunneling Cracks in Multi‐Layer Polymer Thin Films

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Tunneling cracks severely compromise the mechanical integrity of multi‐layer polymer thin films on stiff substrates. Although previous models assume a constant elastic modulus, this study characterizes four candidate thermoset polymers. Their elastic modulus (E$$ E $$), coefficient of thermal expansion (CTE), and glass transition temperature ...

Mechanical and Metallurgical Evaluation of Four Rotary Nickel‐Titanium File Systems: A Multimethod Study

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim To compare four rotary nickel‐titanium (NiTi) file systems (Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo) using a multimethod approach to evaluate their mechanical and metallurgical properties. Materials and Methods Endostar E3 Azure, Endostar E3, VDW.ROTATE, and Mtwo (all size 25/0.06 with an S‐shaped cross‐section; 52 instruments
