The present study aimed to compare the accuracy of estimating the percentage of total body fat (%TBF) among three bioelectrical impedance analysis (BIA) devices: a singlefrequency BIA with four tactile electrodes (SF-BIA4), a single-frequency BIA with eight tactile electrodes (SF-BIA8) and a multi-frequency BIA with eight tactile electrodes (MFBIA8). Dual-energy x-ray absorptiometry (DXA) and h...

OBJECTIVE (1) To investigate the hypothesis that the vertex positive potential (VPP) and the N170 ERP components reported in the face processing literature are two manifestations of the same brain processes whose relative amplitude in a given experiment is dependent on reference electrode; (2) to investigate whether differences in face/object results reported in studies looking at the VPP and N...

This work describes the adaptive use of conventional stainless steel pins-used in unmodified form or coated with carbon paste-as working, counter, and quasi-reference electrodes in electrochemical devices fabricated using cotton thread or embossed omniphobic R(F) paper to contain the electrolyte and sample. For some applications, these pin electrodes may be easier to modify and use than printed...

Oesophageal pH monitoring data are influenced by numerous patient or technique related factors, or both. In this study, data recorded with glass microelectrodes or antimony electrodes, both with external cutaneous Ag/AgCl reference electrodes, connected to two different recording devices are compared. Pearson correlation coefficients regarding the reflux index (% of the investigation time with ...

Carbonized lignin powder was used as a salt bridge for silver-silver chloride reference electrode. This easy-to-prepare electrode exhibited excellent stability in saturated potassium solution. In addition, the electrochemical impedance spectra showed that prepared is stable acidic, neutral, and basic aqueous solutions (pH 1 - 12) has similar impedances to its glass frit equivalent.

Enabling simple three-electrode (3E) setups for solid-state battery cells is important allowing investigation of individual electrodes to shed more light on interface charge transfer and reactions occurring in cells. Two different 3E are compared, their practical value evaluated. A miniaturized reference electrode ( ? -RE) developed from lithium-plated gold wires with a tungsten core providing ...

In electroanalytical measurements, nanoporous glass plugs are widely used to contain the electrolyte solution that forms a salt bridge between the sample and the reference electrode. Even though reference electrodes with plugs made of nanoporous glass (such as Vycor or CoralPor glass) are commercially available and are frequently used, the limits of their use have not been explored thoroughly. ...
