The surface charge of trypanosomatids [PDF]
Anais da Academia Brasileira de Ciências, 2002 The surface charge of trypanosomatids was evaluated by means of the binding of cationic particles, as visualized by electron microscopy and by direct measurements of the electrophoretic mobility of cells. The results obtained indicate that most of the trypanosomatids exhibit a negatively charged surface whose value is species specific and varies ...

Gas–solid interface charge characterisation techniques for HVDC GIS/GIL insulators
High Voltage, 2020 Surface charge accumulation on the spacers is one of the key issues restraining the development of HVDC GIS/GIL. The precise measurement of surface charge properties provides the basis for further study of the surface charge transport mechanism as well ...

Physical Review E, 2017 Experiments in several laboratories have demonstrated that identical materials brought into repeated contact generate unexplained and growing surface charge domains. Here we show that the growth of charge from these experiments can be fitted to a previously developed first-principles model for contact charging based on feedback of random surface ...

The Electrostatic Interaction of a Charged Particle with a Surface: The Effect of Surface Charge Rearrangement [PDF]
Journal of Colloid and Interface Science, 2001 In this paper we investigate the electric interaction between a charged particle and a surface in which the charged ions are capable of moving in response to the electric potential disturbance caused by the approach of the charged particle. Such surfaces include ionic surfactants distributed in air-water interface and charged lipids in bilayer ...
