Reactive-infiltration instabilities in rocks. Fracture dissolution
A reactive fluid dissolving the surface of a uniform fracture will trigger an instability in the dissolution front, leading to spontaneous formation of pronounced well-spaced channels in the surrounding rock matrix. Although the underlying mechanism is similar to the wormhole instability in porous rocks there are significant differences in the physics, due to the absence of a steadily propagati...
متن کاملModel Driven Reactive Applications
Reactive applications (rapps) are of interest because of the explosion of mobile, tablet and web-based platforms. The complexity and proliferation of implementation technologies makes it attractive to use model-driven techniques to develop rapp systems. This article proposes a domain specific language for rapps consisting of stereotyped class models for the structure of the application and stat...
متن کاملReactive Transport Modeling of Phosphate Mineral Dissolution in High-p
Introduction: Phosphate is among the nutrients considered critical for all known life [1-4]. The ion is a component in ATP, DNA, RNA, phospholipid cell membranes and required in numerous fundamental biochemical reactions [5]. Phosphorus, either as phosphate or a more reduced species such as phosphite, is also considered crucial in pre-biotic reactions that may have led to the origin of life on ...
متن کاملDiffusion Controlled Dissolution and Precipitation*
Dissolution and precipitation reactions that occur in biological systems and in non-stirred in vitro systems generally are diffusion-controlled. Subsurface demineralization of tooth enamel in dental caries, which has been the subject of considerable interest, is an example of such processes. In the caries process ions from solubilized tooth mineral, i. e., Ca, P04, and OH, need to be transporte...
متن کاملReductive dissolution of supergrowth carbon nanotubes for tougher nanocomposites by reactive coagulation spinning.
Long single-walled carbon nanotubes, with lengths >10 μm, can be spontaneously dissolved by stirring in a sodium naphthalide N,N-dimethylacetamide solution, yielding solutions of individualised nanotubide ions at concentrations up to 0.74 mg mL-1. This process was directly compared to ultrasonication and found to be less damaging while maintaining greater intrinsic length, with increased indivi...
