We experimentally investigated conductivity and mobility of poly(3-hexylthiophene) (P3HT) doped with tetrafluorotetracyanoquinodimethane $({\mathrm{F}}_{4}\mathrm{TCNQ})$ for various relative doping concentrations ranging from ultralow $({10}^{\ensuremath{-}5})$ to high $({10}^{\ensuremath{-}1})$ active layer thicknesses. Although the measured monotonously increases increasing concentration, mobilities decrease, in agreement previously published work. Additionally, we developed a simple yet...
We investigate conductivity and mobility of different hosts mixed with electron-withdrawing guests in concentrations ranging from ultralow to high. The effect the guest material on host varies systematically guests' LUMO energy relative HOMO, quantitative agreement a recently developed model. For within ∼0.5 eV HOMO dominant process governing transport is competition between formation deep tail DOS state filling. In other cases, interaction dominated by any polar side groups changes...
Abstract A common way of determining the majority charge carriers pristine and doped semiconducting polymers is to measure sign Seebeck coefficient. However, a polarity change coefficient has recently been observed occur in highly polymers. Here, it shown that inversion result density states filling opening hard Coulomb gap around Fermi energy at high doping levels. Electrochemical n‐doping used induce carrier (>1 charge/monomer) model system poly(benzimidazobenzophenanthroline) (BBL). By...
Recent developments in mobile brain-body imaging (MoBI) technologies have enabled studies of human locomotion where subjects are able to move freely more ecologically valid scenarios. In this study, MoBI was employed describe the behavioral and neurophysiological aspects three different commonly occurring walking conditions healthy adults. The experimental were self-paced walking, while conversing with a friend lastly texting smartphone. We hypothesized that gait performance would decrease...
Abstract A major attraction of organic conjugated semiconductors is that materials with new, emergent functionality can be designed and made by simple blending, as extensively used in, e.g., bulk heterojunction solar cells. Herein doped blends based on (OSCs) for thermoelectric applications are critically reviewed. Several experimental strategies to improve performance, measured in terms power factor (PF) or figure‐of‐merit ZT, have been demonstrated recent literature. Specifically,...
The recent upswing in attention for the thermoelectric properties of organic semiconductors (OSCs) adds urgency to need a quantitative description range and energetics hopping transport under relevant circumstances, i.e., around room temperature (RT). In particular, degree which hops beyond nearest neighbor must be accounted at RT is still largely unknown. Here, measurements charge energy doped OSCs are combined with analytical modeling reach univocal conclusion that variable-range proper...
Throughout the world, production, application, and disposal of metalworking fluid (MWF) must adhere to requirements nature environment. Plant-derived oils have been researched as alternative mineral-based cutting fluids they are deemed be more environmentally friendly sustainable. This paper investigates different vegetable- plant-derived in their pure state, blends or commercially available products within industry, measures relative oxidation stability levels ability perform a lubricant. A...
Gait impairments during real-world locomotion are common in neurological diseases. However, very little is currently known about the neural correlates of walking real world and on which regions brain involved regulating gait stability performance. As a first step to understanding how control may be impaired conditions such as Parkinson's disease, we investigated regional activation might predict performance urban environment whilst engaging with secondary tasks healthy subjects.We recorded...

We investigate the suitability of “sequential doping” method organic semiconductors for thermoelectric applications. The consists depositing a dopant (F4TCNQ) containing solution on previously cast semiconductor (P3HT) thin film to achieve high conductivity, while preserving morphology. For very films (∼25 nm), we power factor around 8 μW/mK−2 with conductivity over 500 S/m. increasing thickness, and show decreasing trend, which attribute inability dope deeper parts film. Since thick are...

Adaptation of arm reaching in a novel force field involves co-contraction upper limb muscles, but it is not known how the co-ordination multiple muscle activation orchestrated. We have used intermuscular coherence (IMC) to test whether coherent coupling between pairs responsible for patterns during adaptation field.
