Nucleation and clustering: a microscopic study of the aggregation behaviour in metastable solutions
نویسنده
چکیده
The aggregation state of metastable solutions has been studied by small angle neutron scattering. The variation of the scattering curves was monitored during continuous cooling for aqueous solutions of ND4C1. The analysis of the data indicates the existence of finite-sized domains responsible for the variation of the scattering density on undercooling. The data have been analyzed using a Percus-Yevick hard-sphere model which gives cluster sizes between 10 and 30 nm with an average interparticle distance of 100-200 nm.

Effects of Coating Golegohar-Chadormalu Pellet on Its Behaviour in Direct Reduction Process
A higher bustle temperature in midrex direct reduction process is always desirable due to its positive effect on the productivity and DRI quality. The limit of the bustle temperature is related to the sticking or clustering behaviour of oxide pellets during the reduction in the reactor. It has been well estabilished that coating of oxide pellets by a refractory material decreases its

The influence of aluminum, within the range of 0.08 - 6.16 wt.%, on the microstructure and hardness of as-cast ductile cast iron has been studied. A number of irons of different composition have been made by green sand casting and gravity die casting of appropriate design to provide the experimental materials. It has been found that Al addition and higher cooling rates in permanent mould castin...
متن کاملHomogeneous crystal nucleation near a metastable fluid-fluid phase transition.
Several scenarios exist for the protein crystallization and aggregation in solutions near a metastable fluid-fluid phase separation below the solubility line. Based on computations, it was proposed that the fluid-fluid critical point enhances the crystallization rate by many orders of magnitude, while, based on experiments, it was proposed that the fluid-fluid spinodal controls the crystallizat...
