Electrostatic complexation of spheres and chains under elastic stress
We consider the complexation of highly charged semiflexible polyelectrolytes with oppositely charged macroions. On the basis of scaling arguments we discuss how the resulting complexes depend on the persistence length of the polyelectrolyte, the salt concentration, and the sizes and charges of the chain and the macroions. We study first the case of complexation with a single sphere and calculat...
متن کاملStress-Induced Nanoparticle Crystallization
We demonstrate for the first time a new mechanical annealing method that can significantly improve the structural quality of self-assembled nanoparticle arrays by eliminating defects at room temperature. Using in situ high-pressure small-angle X-ray scattering, we show that deformation of nanoparticle assembly in the presence of gigapascal level stress rebalances interparticle forces within nan...
متن کاملNonlinear static and dynamic behaviors of a microresonator under discontinuous electrostatic actuation
This article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. The electrostatic actuation was induced by applying AC-DC voltage between the microbeam and electrode plate. In contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. In additio...
متن کاملMicrobatch crystallization under oil — a new technique allowing many small - volume crystallization trials
An approach to rapid protein crystallization using very small samples is described. A computer controlled microdispenser is used to make crystallization samples as microbatch droplets under oil. Samples of 1—2 ~l are dispensed ready-mixed and with good precision. The samples are protected from evaporation, contamination and physical shock by the oil. When favourable conditions for crystallizati...
متن کاملElectrostatic modes in collisional complex plasmas under microgravity conditions.
A linear dispersion relation in a highly collisional complex plasma, including ion drift, was derived in the light of recent PKE-Nefedov wave experiment performed under microgravity conditions onboard the International Space Station. Two modifications of dust density waves with wave frequencies larger than the dust-neutral collision frequency were obtained. The relevance to the space observatio...
