We present and characterize a versatile experimental setup which allows for excitation and detection of Rydberg atoms in quantum gases. The novel concept of the setup features two charged particle detectors and eight electrical field plates inside the vacuum chamber, which allows the detection and manipulation of Rydberg atoms. The setup presented here is applicable to all atomic species used i...

Laboratory studies, numerical simulations, and desert field tests indicate that aeolian dust transport can generate atmospheric electricity via contact electrification or “triboelectricity.” In convective structures such as dust devils and dust storms, grain stratification leads to macroscopic charge separations and gives rise to an overall electric dipole moment in the aeolian feature, similar...

Emulsion stability is a fundamental determination for separation technologies. We use the critical electric field (CEF) and viscosity changes in DC electrorheological (ER) experiments in dynamic mode to establish the level of stability of water-in-crude oil emulsions previously studied through bottle tests. The CEF value corresponds to the value of electric field at which the current reaches 95...

In this work, we study the effect of strong electric fields on a polymer/graphene composite and resulting morphology upon its dielectric breakdown. Our model system was produced by compounding up to 0.25 wt % graphene nanoplatelets (GNP) into poly(ethylene-co-vinyl acetate) (EVA), which is soft polymer with low melt viscosity. A field 400 Vrms/mm applied EVA/GNP in melt. The sample’s resistance...

Article history: Received 6 August 2012 Received in revised form 31 January 2013 Accepted 6 February 2013 We report preliminary results of a new observational study of microwave-frequency electromagnetic radiation that is emitted by lightning discharge processes. Radiation was observed with a ceramic patch antenna and a digital radio receiver tuned to a center frequency of 1.63 GHz and a bandwi...

Lipid peroxidation (LPO) of unsaturated fatty acids in bimolecular lipid membranes (BLM), induced by ultraviolet irradiation [l-3] or by chemical agents [4], brings about an increase in conductivity of these membranes. For BLM prepared from egg phosphatidylcholine/cholesterol mixture this effect is accounted for by the rise of proton permeability [3,5]; the maximal conductivity enhancement bein...
