It is estimated that about 18 million people worldwide suffer from dementia and it is projected to increase to about 35 million by the year 2025. All types of dementia occur due to an aberration in memory retention and development, caused by malfunctioning neurons. Experimental investigation of the dynamics of biological networks is a fundamental step towards understanding how the nervous syste...

All-vanadium redox flow battery (VRFB) is a promising energy storage technique. Flow fields play crucial role in distributing the electrolyte into electrode uniformly, but their performance characteristics under different parameters are still unclear. In this work, taking total pressure drop and overpotential as characterizations, influence of operating conditions on serpentine field (SFF) inte...

Uniform patterning of cells is highly desirable for most cellular studies involving cell-cell interactions but is often difficult in an in vitro environment. This paper presents the development of a collagen-coated planar interdigitated ring electrode (PIRE) array utilizing positive dielectrophoresis to pattern cells uniformly. Key features of the PIRE design include: (1) maximizing length alon...

We present experimental and theoretical results on suspensions of silica rods in DMSO-water, subjected to an applied electric field. The experimental results indicate that, if the electrode used for generating the electric field is in direct contact with the suspension, a fraction of the rods close to the electrode surface does not stand parallel to the field but instead lies flat on the electr...

Li metal was electrodeposited and electrochemically dissolved on an ultra-micro-electrode to model the transition of morphology three-dimensional structure a electrode during cycles. The first electrodeposition produced uniform dense column structure, but solid electrolyte interphase (SEI) remained next electrochemical dissolution. accumulation SEI residue obstructs in following cycles increase...

Liquid pumping can occur along the outer surface of an electrode under a DC electric field. For biological applications, a better understanding of the ionic solution pumping mechanism is required. Here, we fabricated CNT wire electrodes (CWEs) and tungsten wire electrodes (TWEs) of various diameters to assess an ionic solution pumping. A DC electric field created by a bias of several volts pump...

PURPOSE This study investigates a large-area plane-parallel ionization chamber (LAC) for measurements of dose-area product in water (DAPw ) in megavoltage (MV) photon fields. METHODS Uniformity of electrode separation of the LAC (PTW34070 Bragg Peak Chamber, sensitive volume diameter: 8.16 cm) was measured using high-resolution microCT. Signal dependence on angle α of beam incidence for squar...
