Direct Experimental Evidence for Differing Reactivity Alterations of Minerals following Irradiation: The Case of Calcite and Quartz
Isabella Pignatelli, Aditya Kumar, Kevin G. Field +5
Concrete, a mixture formed by mixing cement, water, and fine and coarse mineral aggregates is used in the construction of nuclear power plants (NPPs), e.g., to construct the reacto…
Topological Control on Silicates Dissolution Kinetics
Isabella Pignatelli, Aditya Kumar, Mathieu Bauchy +1
Like many others, silicate solids dissolve when placed in contact with water. In a given aqueous environment, the dissolution rate depends highly on the composition and the structu…
Does a dissolution-precipitation mechanism explain concrete creep in moist environments?
Isabella Pignatelli, Aditya Kumar, Rouhollah Alizadeh +3
Long-term creep (i.e., deformation under sustained load) is a significant material response that needs to be accounted for in concrete structural design. However, the nature and or…
Nature of Radiation-Induced Defects in Quartz
Bu Wang, Yingtian Yu, Isabella Pignatelli +2
Although quartz (-form) is a mineral used in numerous applications wherein radiation exposure is an issue, the nature of the atomistic defects formed during radiation-induce…
Stretched Exponential Relaxation of Glasses at Low Temperature
Yingtian Yu, Mengyi Wang, Dawei Zhang +3
The question of whether glass continues to relax at low temperature is of fundamental and practical interest. Here, we report a novel atomistic simulation method allowing us to dir…
