Motion of a Single Bead on a Bead Row: Theoretical Investigations
The motion of a single bead on an inclined "line" made up of juxtaposed identical beads is analytically investigated. Initially, an entirely analytical method is presented in some detail: the problem is tractable with the usual analytical tools as long as any slip motion is ignored. Under these conditions, we show I) the existence of a steady regime within a certain range of line slopes and it)...
متن کاملYoctoliter thermometry for single-molecule investigations: a generic bead-on-a-tip temperature-control module.
A new temperature-jump (T-jump) strategy avoids photo-damage of individual molecules by focusing a low-intensity laser on a black microparticle at the tip of a capillary. The black particle produces an efficient photothermal effect that enables a wide selection of lasers with powers in the milliwatt range to achieve a T-jump of 65 °C within milliseconds. To measure the temperature in situ in si...
متن کاملSaltating motion of a bead in a rapid water stream.
This paper experimentally and numerically investigates the two-dimensional saltating motion of a single large particle in a shallow water stream down a steep rough bed. The experiment is prototypical of sediment transport on sloping beds. Similar to the earlier experimental results on fine particles entrained by a turbulent stream, we found that most features of the particle motion were control...
متن کاملRolling motion of a bead in a rapid water stream.
This paper investigates the two-dimensional rolling motion of a single large particle in a shallow water stream down a steep rough bed from both an experimental and a theoretical point of view. The experiment is prototypal of sediment transport on sloping beds. Two theoretical models are presented. The first model uses the mean kinetic energy balance to deduce the average particle velocity and ...
متن کاملDeterministic bead-in-droplet ejection utilizing an integrated plug-in bead dispenser for single bead–based applications
This paper presents a deterministic bead-in-droplet ejection (BIDE) technique that regulates the precise distribution of microbeads in an ejected droplet. The deterministic BIDE was realized through the effective integration of a microfluidic single-particle handling technique with a liquid dispensing system. The integrated bead dispenser facilitates the transfer of the desired number of beads ...
