The application of temporary electro-stimulation is necessary in acute myocardial infarction complicated by the appearance of symptomatic bradycardia, AV conduction disturbances and asystolia. During the last two years, 38 of 892 patients (4.2%) with the diagnosis of acute myocardial infraction with ST segment elevation, required temporary electro-stimulation (27 with inferior infractions and 1...

A new method of direct-write nanolithography that is able to rapidly etch silica surfaces under a scanning atomic force microscopy (AFM) probe in tapping mode (TM) reported. In this lithography technique, are etched using recently described electro-chemo-mechanical phenomenon frequency enhanced electrochemical pressure solution (FEEPS). FEEPS, the AFM tip generates oscillations Stern potential ...

Lithium-ion batteries rely on particulate porous electrodes to realize high performance, especially fast-charging capabilities. To minimize the particle-wise reaction heterogeneities, a deeper understanding of these at mesoscale, i.e., hundreds particles, is necessary. Here, we report that seemingly random heterogeneities are actually controlled by interplay between non-equilibrium material the...

Nonuniform electrodeposition of lithium during charging processes is the key issue hindering development rechargeable Li metal batteries. This deposition process largely controlled by solid electrolyte interphase (SEI) on surface and design artificial SEIs an essential pathway to regulate Li. In this work, electro-chemo-mechanical model built implemented in a phase-field modelling understand co...

The expression of the anti-apoptotic molecules Bcl-2 and transforming growth factor-beta 1 is known to confer protective effects on the cerebral ischemia-reperfusion injury. The current study investigated the expression levels of Bcl-2 and transforming growth factor-beta 1 in response to multiple pre-ischemia electro-acupuncture at acupoints Zusanli (ST36) and Fengchi (GB20) stimulation. Rats w...

The physical mechanisms responsible for the electrical orientation and electrical rotation of metal nanowires suspended in an electrolyte as a function of frequency of the applied ac electric field are examined theoretically and experimentally. The alignment of a nanowire in an ac field with a fixed direction is called electro-orientation. The induced constant rotation of a nanowire in a rotati...

As oil fields age, artificial lift systems are required to maintain production levels when reservoir pressures get too low. Failure of an ESP in a well can stop production or even lead to a dangerous event. ESPs are fitted with downhole monitoring units that transmit streams of data back to the surface including: motor temperature, pump intake pressure, intake temperature motor vibration, and m...
