Use of self-assembled monolayers to control interface bonding in a model study of interfacial fracture (open access)

Use of self-assembled monolayers to control interface bonding in a model study of interfacial fracture

The relationship between the nature and spatial distribution of fundamental interfacial interactions and fracture stress/fracture toughness of a glassy adhesive-inorganic solid joint is not understood. This relationship is important from the standpoint of designing interfacial chemistry sufficient to provide the level of mechanical strength required for a particular application. In addition, it is also important for understanding the effects of surface contamination. Different types of contamination, or different levels of contamination, likely impact joint strength in different ways. Furthermore, the relationship is also important from the standpoint of aging. If interfacial chemical bonds scission over time due to the presence of a contaminant such as water, or exposure to UV, etc, the relationship between joint strength/fracture toughness and interface strength is important for predicting reliability with time. A fundamental understanding of the relationship between joint strength and fundamental interfacial interactions will give insight into these issues.

Volatile impurities in the ceramic form for the Plutonium Immobilization Project (PIP) (open access)

Volatile impurities in the ceramic form for the Plutonium Immobilization Project (PIP)

The primary goal for the impurity tests performed at SRS was to determine the maximum level of volatile impurities that can be accommodated into the ceramic form without significantly affecting product properties. The properties investigated in this study are the apparent porosity and the phase assemblage.

Waste Analysis Plan for the Low Level Burial Grounds [CANCELLED] Reissued as HNF-5841

Canceled see HNF-5841 Rev 0. This waste analysis plan (WAP) has been prepared for the Low-Level Burial Grounds which are located in the 200 East and West Areas of the Hanford Facility, Richland, Washington. This WAP documents the methods used to characterize, obtain and analyze representative samples of waste managed at this unit.
