The impact of electrical current on the structure single free-standing Be-doped GaAs nanowires grown a Si 111 substrate is investigated. Single have been structurally analyzed by X-ray nanodiffraction using synchrotron radiation before and after application an current. conductivity measurements in their as-grown geometry realized via W-probes installed inside dual-beam focused ion beam/scanning...

In 1879 E. H. Hall observed that when an electrical current passes through a sample placed in a magnetic field, a potential proportional to the current and to the magnetic field is developed across the material in a direction perpendicular to both the current and to the magnetic field [1]. This effect is known as the Hall effect, and is the basis of many practical applications and devices such ...

FocA belongs to the formate-nitrate transporter family and plays an essential role in the export and uptake of formate in organisms. According to the available crystal structures, the N-terminal residues of FocA are structurally featureless at physiological conditions but at reduced pH form helices to harbor the cytoplasmic entrance of the substrate permeation pathway, which apparently explains...

Motor electrical current signature analysis (MCSA) is sensing an electrical signal containing current components that are direct by-product of unique rotating flux components. Anomalies in operation of the motor modify harmonic content of motor supply current. This paper presents brief introductory review of the method including fundamentals, fault detection techniques and current signatures of...

BACKGROUND There are few publications on facial seborrhea treatment. A focused therapy is needed. OBJECTIVE Our aim was to evaluate the efficacy of electrothermolysis of the sebaceous glands. METHODS In the preliminary studies, histologic changes in the cheek skin by electrothermolysis were examined by light microscopy. In the clinical studies, 15 adult women subjects with facial seborrhea ...

Microbial electrochemical systems (MESs) use microorganisms to covert the chemical energy stored in biodegradable materials to direct electric current and chemicals. Compared to traditional treatment-focused, energy-intensive environmental technologies, this emerging technology offers a new and transformative solution for integrated waste treatment and energy and resource recovery, because it o...

We show that a nanofluidic device consisting of a solution-filled cavity bounded by two closely spaced parallel electrodes can amplify the electrical current from redox molecules inside the cavity by a factor of approximately 400 through redox cycling. The noise spectral density of this signal agrees quantitatively with the calculated fluctuations in the number of molecules inside the cavity du...

New developments in accelerating wound healing can have immense beneficial socioeconomic impact. The wound healing process is a highly orchestrated series of mechanisms where a multitude of cells and biological cascades are involved. The skin battery and current of injury mechanisms have become topics of interest for their influence in chronic wounds. Electrostimulation therapy of wounds has sh...
