Relationship between Microstructure, Properties and HICC Resistance of HSLA steel weld metals
… studied in some detail due to their hydrogen trapping capacity. Fractographic studies of hydrogen charged tensile samples were carried out to study the effect of microstructure and hydrogen content on the fracture micromechanisms. A critical hydrogen content (Ck) was estimated for each weld …

Modelling Precipitation of Carbides in Martensitic Steels
… that carbide particles can act as hydrogen trapping sites, thus reducing the risk of embrittlement. The thesis begins with a review of the physical metallurgy of secondary hardening steels and the phenomena of hydrogen embrittlement and hydrogen trapping. The basic theory for the …

Hydrogen embrittlement in nuclear and bearing applications: from quantum mechanics to thermokinetics and alloy design
… phases, optimised for helium and/or hydrogen trapping capacity, the novel alloys present the benefits of such trapping species with respect to embrittlement resistance. Such species have been studied in depth with respect to their interactions with hydrogen, establishing a novel mechanism of …

A statistical approach to urban stormwater detention planning
… which represent the combinations of storage capacity, treatment rate, and the sewer system runoff trapping capacity, which provide a fixed level of runoff control. A pollutant load model was also formulated, based on a first-order washoff model. This model was used to define pollutant control …

Extracellular DNA-Based Trapping of Heavy Metals by Root Border Cells
… that, as in animals, extracellular DNA (exDNA) trapping plays a central role in defense, but the mechanism remains poorly understood. Upon immersion in water, border cells and the associated exDNA mucilage structures rapidly disperse and are primed for function in defense of the root tip. The …

The Investigation of Primary and Secondary Modifiers in the Extraction and Separation of Neutral and Ionic Pharmaceutical Compounds with Pure and Modified Carbon Dioxide
… from the matrix into the bulk fluid as well as trapping or concentration of the analyte prior to analysis. In the first phase of this research, the trapping capacities of three solid-phase traps (glass beads, 50/50 (w/w) glass beads/octadecylsilica), 50/50 (w/w) Porapak Q®/glass beads) were …
