Assurance Views of Testimony [PDF]

open access: yes, 2019
Assurance theories of testimony attempt to explain what is distinctive about testimony as a form of epistemic warrant or justification. The most characteristic assurance theories hold that a distinctive subclass of assertion (acts of “telling”) involves ...

Geometry‐Based Scan Curve Analysis: Rapid Method for the Evaluation of Scan Strategies in Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents rapid evaluation methods for scan strategies in powder bed fusion (PBF) of polymers with a NIR laser as an example for its application. It uses line buffer‐based calculations and point density fields to predict the performance of four different scan strategies. The methods show promising results in laser‐based PBF of polymer samples,

Influence of a Standard Heat Treatment on the Microstructure and Properties of Inconel X‐750 Produced by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Associations among Wine Grape Microbiome, Metabolome, and Fermentation Behavior Suggest Microbial Contribution to Regional Wine Characteristics

open access: yesmBio, 2016
Regionally distinct wine characteristics (terroir) are an important aspect of wine production and consumer appreciation. Microbial activity is an integral part of wine production, and grape and wine microbiota present regionally defined patterns ...

Development and Validation of ReaxFF Reactive Force Field for Hydrocarbon Chemistry Catalyzed by Nickel [PDF]

open access: yes, 2010
To enable the study of hydrocarbon reactions catalyzed by nickel surfaces and particles using reactive molecular dynamics on thousands of atoms as a function of temperature and pressure, we have developed the ReaxFF reactive force field to describe ...

Process Parameter and Dimension‐Dependent Mn Vaporization During Laser Powder Bed Fusion of an Fe–Mi–Si–Cr‐Based Shape Memory Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
The functional properties of Fe–Mn–Si–Cr‐based shape memory alloys are influenced, among other things, by their chemical composition. Here, the vaporization of Mn, the most volatile element of the alloy, is investigated. It is shown that the process parameters make noninterchangeable contributions to the vaporization and that vaporization differences ...

Rockburst management in Canadian hard rock mines

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2019
Rockburst is a complex mining-induced phenomenon that remains difficult to be quantified. In particular, geological conditions contributing to rockbursts are more variable than those in many conventional engineering approaches.

Cobalt improves nickel hydroxide electrodes for batteries [PDF]

open access: yes, 1969
Positive nickel hydroxide electrodes containing 20 mole percent of cobalt hydroxide are more efficient than when impregnated to the same degree by weight with nickel hydroxide alone. Charge-acceptance and oxygen-evolution tests indicate cobalt electrodes

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.
