Women aged 67-84 yr were randomly assigned to either resistance exercise (RE, n = 15) or control group (C, n = 14). RE group completed 10 wk of resistance training, whereas C group maintained normal activity. Blood samples were obtained from the RE group (at the same time points as for resting C) at rest, immediately after resistance exercise, and 2 h after(More)
Let it grow: The conjugated polymer poly(3,4-ethylenedioxythiophene) (PEDOT) was synthesized with heparin as the counterion to form a cell culture substrate. The surface of PEDOT:heparin in the neutral state associated biologically active growth factors. Electrochemical in situ oxidation of PEDOT during live cell culture decreased the bioavailability of the(More)
optical and electronic properties suitable for applications in e.g. transistors, light emitting diodes and photovoltaic cells. 1-10 All such devices contain several interfaces, metal-organic and/or organic/organic, that effect significantly performance and functionality. Much effort consequently has been invested in describing the energetics governing(More)
Printed electronics are considered for wireless electronic tags and sensors within the future Internet-of-things (IoT) concept. As a consequence of the low charge carrier mobility of present printable organic and inorganic semiconductors, the operational frequency of printed rectifiers is not high enough to enable direct communication and powering between(More)
Substantial potential steps ∼ 0.5 eV are frequently observed in organic multilayers of donor and acceptor molecules. Often such potential steps depend on the order in which the individual layers are deposited, or on which substrate they are deposited. In this paper we outline a model for these potential steps, based upon integer charge transfer between(More)
Amphiphilic semiconducting copolymer as compatibility layer for printing polyelectrolyte-EGOFET: Polyelectrolyte-gated organic field effect transistor. Abstract We report a method for inkjet-printing an organic semiconductor layer on top of the electrolyte insulator layer in polyelectrolyte-gated OFETs by using a surface modification treatment to overcome(More)
Organic photovoltaic is under intense development and significant focus has been placed on tuning the donor ionization potential and acceptor electron affinity to optimize open circuit voltage. Here we show that for a series of regioregular-poly(3-hexylthiophene):fullerene bulk heterojunction organic photovoltaic devices with pinned electrodes, integer(More)
We systematically show the effect of UV-light soaking on surface electronic structure and chemical states of solution processed ZnO nanoparticle (ZnONP) films in UHV, dry air and UV-ozone. UV exposure in UHV induces a slight decrease in work function and surface-desorption of chemisorbed oxygen, whereas UV exposure in presence of oxygen cause an increase in(More)
