Microtensile bond strength of current adhesive systems when compared to cohesive strength of sound dentin and a resin-based composite

Materials Research, 2004
Purpose: To evaluate the microtensile bond strength (µTBS) to dentin of 4 adhesive systems, the micromorphology of the adhesive/dentin interface and to compare the results to the µTS (cohesive strength) of sound dentin and resin composite.

Na2S in‐situ infiltrated in actived carbon as high‐efficiency presodiation additives for sodium ion hybrid capacitors

Carbon Neutralization
Sodium ion hybrid capacitors (SIHC) are emerging as promising next‐generation energy storage devices with high energy/power density. Presodiation is an essential part of SIHC production due to the lack of sodium sources in the cathode and anode. However,

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Penetration of a glass-faced transparent elastomeric resin by a lead-antimony-cored bullet [PDF]

, 2008
The penetration of the lead antimony-cored 7.62 mm × 51 mm bullet into a glass- faced polyurethane elastomeric polymer resin has been studied. The resulting craters in the resin contained elongated bullet core material that had a significant amount of ...

Janus structure breaks the solar incidence angular constraint insu photothermal anti-icing

Nature Communications
Angle-sensitive sunlight absorption in state-of-the-art photothermal anti-icing surfaces becomes an Achilles’ heel: geometric shadowing and Fresnel reflection critically degrade broadband harvesting under oblique (incident light >45°) or low solar ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
