Spray pyrolysis method has a disadvantage of nozzle plugging and conventional heating model causes large temperature gradient, which leads to uneven heated reactants. In this study, cerium chloride heptahydrate Venturi reactor were used as raw material core equipment, respectively. The technology microwave was combined prepare single-phase sphere-like oxide. mean size the particles near 80nm. p...

In this Tutorial Review, we make the point that a true understanding of trends in reactivity (as opposed to measuring or simply computing them) requires a causal reactivity model. To this end, we present and discuss the Activation Strain Model (ASM). The ASM establishes the desired causal relationship between reaction barriers, on one hand, and the properties of reactants and characteristics of...

The ionic gelation process for the synthesis of chitosan nanoparticles was carried out in microdroplet reactions. The synthesis could be stopped instantaneously at different time points by fast dilution of the reaction mixture with DI water. Using this simple technique, the effect of temperature and reactant concentrations on the size and distribution of the nanoparticles formed, as a function ...

Background Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are most commonly employed acute phase reactants in follow up of patients with Familial Mediterranean Fever (FMF). As a rule CRP increases during FMF attacks but it returns to normal values in attack free periods. Persistently elevated acute phase reactants in attack free periods can be occasionally observed in patient...

Transverse diffusion of laminar flow profiles (TDLFP) was recently suggested as a generic approach for mixing reactants inside a capillary microreactor. Conceptually, solutions of reactants are injected inside the capillary by high pressure as a series of consecutive plugs. Because of the laminar nature of the flow inside the capillary, the nondiffused plugs have parabolic profiles with predomi...

Results A boy born from non-consanguineous parents at the age of 2 years presented with livedo reticularis associated to elevation of acute phase reactants and recurrent episodes of arthralgia, fever and hypertension responsive to prednisone. At the age of 6 years he presented a haemorrhagic stroke of the left temporal lobe. A skin biopsy was consistent with a diagnosis of polyarteritis. The pa...

We report on numerical simulations of acid erosion in a fractured specimen of Carrara marble. The simulations combine two recent advances in lattice-Boltzmann methodology to accurately and efficiently calculate the velocity field in the pore space. A tracer diffusion algorithm was then used to calculate the distribution of reactants in the fracture, and the local erosion rate was obtained from ...

Many industrial incidents are caused by thermal runaway reactions. Therefore, a good understanding of runaway reactions is necessary to predict and control reactive hazards. A detailed kinetic modeling approach is proposed to simulate runaway reactions under industrial conditions. This paper addresses the first step of this approach-mechanism generation. Computational chemistry was employed to ...
