Induced electrical potentials in bone by ultrasound irradiation

Ion irradiation induced structural and electrical transition in graphene.

The relationship between the electrical properties and structure evolution of single layer graphene was studied by gradually introducing the gallium ion irradiation. Raman spectrums show a structural transition from nano-crystalline graphene to amorphous carbon as escalating the degree of disorder of the graphene sample, which is in correspondence with the electrical transition from a Boltzmann...

Irradiation induced electrical conductivity in polymeric thin films

Scientific objectives of this project are: (1) To produce and characterise uniaxially charge conducting ion tracks in thin polymeric films with high energy ion beam irradiation. (2) To understand the charge transport mechanisms within and as well as across ion tracks, which have been identified and shown to occur via electron transport across the carbon clusters that were formed within these io...

System Potentials, a Novel Electrical Long-Distance Apoplastic Signal in Plants, Induced by Wounding

Systemic signaling was investigated in both a dicot (Vicia faba) and a monocot (Hordeum vulgare) plant. Stimuli were applied to one leaf (S-leaf), and apoplastic responses were monitored on a distant leaf (target; T-leaf) with microelectrodes positioned in substomatal cavities of open stomata. Leaves that had been injured by cutting and to which a variety of cations were subsequently added caus...

MECHANISMS OF BLOOD FLOW INCREASE INDUCED BY ELECTRICAL STIMULATION

Previous studies have shown that electrical stimulation (ES) increases blood flow, but the exact mechanisms are not clear. The present study was designed to clarify some of the underlying mechanisms involved in this phenomenon. White adult rabbits Lt.-6 months old were used. Animals were anesthetized by sodium pentobarbital (40 mg/kg, IV) and skin blood flow in the thoracic back was recorde...
