AbstractCapillary flow is the spontaneous wicking of liquids in narrow spaces without the assistance of external forces. Examples of capillary flow can be found in numerous applications ranging from controlling and transporting fuel in spacecrafts to printed electronics manufacturing. Open rectangular microchannels often appear in these applications, with the lack of a top resulting in a complex free-surface morphology and evaporation. Here, we present a brief overview of this topic and discuss some recent advances.

AbstractScanning probe techniques have evolved significantly in recent years to detect surface morphology of materials down to subnanometer resolution, but without revealing spectroscopic information. In this review, we discuss recent advances in scanning probe techniques that capitalize on light-induced forces for studying nanomaterials down to molecular specificities with nanometer spatial resolution.

Safe and secure transportation of liquid hot metal in steel plants is very challenging. About ninety percent of transportation is by means of locomotives. Sloshing is a common phenomenon in open container liquid transportation due to external excitation. Non-linear sloshing dynamics of liquid hot metal in ladle due to locomotive movement is the prime consideration of this paper. Liquid hot metal inside the ladle has been considered in the line of an equivalent mechanical system. Resulting forces and moments acting on the ladle inside wall are considered equal in all senses. An equivalent mechanical dynamic system representation of sloshing by bond graph modellinghas been formulated by keeping records in a satisfactory way.Future research scopes has been identifiedin parallel with an outline mapped. Hot metal liquid has two distinct components of the hydrodynamic pressure in consideration of rigid containershas been identified. Bottom segment of the molten metal column moves unison with the ladleandis directlyproportional with the acceleration of the ladle. Whereas the second one ‘convective’ pressure at the free surface, particularly experiences the sloshing tendency due to external forces.
