evaporation of micro-liter drops from solid surfaces at room condition is mainly governed by diffusion. therefore, there should be no difference between evaporation rate of sessile and pendant drops. however, some studies indicate a difference and explain the difference using buoyancy. the objective here is to reconcile the inconsistency in the literature. for that, first, by comparing two iden...

A 2-hydroxyazobenzene platform has been evaluated to photorelease protons in aqueous solutions. Three different systems relying on molecular, supramolecular and polymeric strategies have been investigated in order to tune the water solubility and the thermodynamic and kinetic properties. This paper first reports on the syntheses and the physico chemical analyses for each system. Subsequently, w...

Water droplets can jump during vapor condensation on solid benzene near its melting point. This phenomenon, which can be viewed as a kind of micro scale steam engine, is studied experimentally and numerically. The latent heat of condensation transferred at the drop three phase contact line melts the substrate during a time proportional to R (the drop radius). The wetting conditions change and a...

Optimizing Rural Water Supply Network (RWSN) is the basis for improving rural people’s lives and health. Currently, RWSN in China relatively backward can no longer meet needs of unified management water resources. To optimize RWSN, this study innovatively established a Multi-Objective Optimization Mathematical Model (MOMM) combining economic factors reliability. This experiment first analyzes c...

in this paper, an intelligent controller is applied to control omni-directional robots motion. first, the dynamics of the three wheel robots, as a nonlinear plant with considerable uncertainties, is identified using an efficient algorithm of training, named lolimot. then, an intelligent controller based on brain emotional learning algorithm is applied to the identified model. this emotional lea...
