Unfolding collapsed polyelectrolytes in alternating-current electric fields

We investigate the unfolding of single polyelectrolyte (PE) chains collapsed by trivalent salt under the action of alternating-current (AC) electric fields through computer simulations and theoretical scaling. The results show that a collapsed chain can be unfolded by an AC field when the field strength exceeds the direct-current (DC) threshold and the frequency is below a critical value, corre...

Low dose, alternating electric current inhibits growth of prostate cancer.

BACKGROUND A number of minimally invasive technologies exist for the treatment of prostate cancer (CaP), each with their associated morbidities. We sought to test the efficacy of low dose alternating electric current (LDAEC) to inhibit CaP growth in a preclinical setting and determine its effect on normal tissue. METHODS In the first study, two power settings, 15 or 25 mA of current, and two ...

Alternating Current Electrospraying

Electrospraying has attracted the attention of many researchers, ranging from analytical chemists to physicists, not only because of the rich physics associated with it, but also due to its wide-ranging applicability. Therefore, considerable research has been devoted to exploring this interfacial phenomenon. However, there still are areas of electrospraying that have remained unexplored. Until ...

Alternating Current Theory -

1 November 2001 Alternating Current Theory J R Lucas An alternating waveform is a periodic waveform which alternate between positive and negative values. Unlike direct waveforms, they cannot be characterised by one magnitude as their amplitude is continuously varying from instant to instant. Thus various forms of magnitudes are defined for such waveforms. The advantage of the alternating wavefo...
