Development of highly porous and robust hydrogen bonded organic frameworks (HOFs) for high-pressure methane and hydrogen storage remains a grand challenge due to the fragile nature of hydrogen bonds. Herein, we report a strategy of constructing the double

Effects of hydrogen on the evolution of 4130 steel microstructure as a result of tensile loading

July 12, 2024
Author(s)
Zack Buck, May Ling Martin, Damian Lauria, Jason Killgore, Peter Bradley, Yan Chen, Ke An, Matthew Connolly
Neutron diffraction and Scanning Kelvin Probe Force Microscopy (SKPFM) were used to study the evolution of lattice strain, dislocation density, and phase partitioning of a ferrite/martensite pressure vessel steel (AISI 4130) that resulted from tensile

Entanglement kinetics in polymer melts are chemically specific

July 3, 2024
Author(s)
Benjamin Dolata
We investigate the universality of entanglement kinetics in polymer melts. We compare predictions of a recently developed constitutive equation for disentanglement to molecular dynamics simulations of both united-atom polyethylene and Kremer-Grest models

Effect of Micellar Morphology on the Temperature-Induced Structural Evolution of ABC Polypeptoid Triblock Terpolymers into Two-Compartment Hydrogel Network

Whirang Cho, Lucas Flagg, Christopher Stafford, Jeremiah Woodcock, Daniel Burnett, Anett Kondor, Douglas Fox, John Hoffmann
Polymer-based functional surface coatings are extensively used in advanced technologies, including optics, energy, and environmental applications. Surface thermodynamic properties profoundly impact the molecular interactions that control interfacial

Predicting the toughness of compatibilized polymer blends

June 19, 2024
Author(s)
Robert Ivancic, Debra Audus
Polymer blends can yield superior materials by merging the unique properties of their components. However, these mixtures often phase separate, leading to brittleness. While compatibilizers can toughen these blends, their vast design space makes

Assessing girth weld quality of pipeline steels and their susceptibility to hydrogen embrittlement

June 16, 2024
Author(s)
Zack Buck, Newell Moser, May Ling Martin, Nicholas Derimow, Damian Lauria, Enrico Lucon, Douglas Stalheim, Peter Bradley, Matthew Connolly
Hydrogen is known to cause premature failure in various steel infrastructures due to effects of embrittlement, which is particularly detrimental to ferritic steel structures such as pipelines and pressure vessels. Therefore, understanding the

Vertically Graded FeNi Alloys with Low Damping and a Sizeable Spin-Orbit Torque
