Bio-chemical processes have recently become the core of several studies in the geoengineering field, where the emphasis is placed on new and emerging applications. Microbially Induced Calcite Precipitation has been introduced as an alternative cementation ...
A better understanding of silica dissolution-precipitation reactions at high pH aqueous solutions allows for promotion of favorable (e.g., pozzolanic) reactions and mitigation of deleterious (e.g., alkali-silica) reactions in concrete. In this paper, the k ...
We studied the interdependent effects of phosphate, silicate and Ca on the formation of Fe(III)-precipitates by oxidation of 0.5 mM Fe(II) in near-neutral bicarbonate-buffered aqueous solutions at concentrations relevant for natural water resources. Comple ...
The spatial distribution of snow in the mountains is highly heterogeneous, and processes behind this heterogeneity are not yet understood quantitatively. Based on (i) increasing accuracy and spatial coverage of remotely sensed snow depth maps, which have b ...
The effects of thermal treatments on a Co-Ni-Cr super-alloy in the temperature range from 250 degrees C to 900 degrees C, resulting in secondary hardening, have been studied by Mechanical Spectroscopy. The simultaneous evolution of the internal friction sp ...
A comprehensive simulation approach integrating solidification, homogenization, and precipitation during aging has been used to predict the formation of gamma/gamma' microstructures in the AM1 nickel-based superalloy. The particle size distribution of intr ...
The influence of concurrent precipitation on recrystallization is analyzed by comparing the nucleation and growth behavior of P ({011} 〈566〉), Cube ({001} 〈100〉), and 20 deg ND-rotated Cube ({001} 〈310〉, NDcube)-oriented grains in Al-xMn-Fe-Si (x = 0, 0.4, ...
Metallic nanoclusters form a family of novel materials with atomically defined hybrid organic/inorganic structures. Among these materials, clusters containing 44 silver atoms have emerged as one of the most interesting, because of their exceptional electro ...
Annealing of supersaturated AA3xxx alloys at low temperatures usually results in sluggish recrystallization kinetics. This is due to the joint effect of the following factors: low nucleation rate, reduced grain boundary mobility, and large amount of fine p ...
The precipitation of an AA2618 Al-Cu-Mg alloy is monitored during isothermal holdings and continuous coolings. The Time-Temperature-Property and Continuous-Cooling-Precipitation diagrams of AA2618 are obtained using in-situ resistivity and differential sca ...
