Low band gap donor-acceptor conjugated polymers toward organic solar cells applications
No full textAbstract: Mixtures of conjugated polymers and fullerenes command considerable attention for application in organic solar cells. To increase their efficiency, the design of new materials that absorb at longer wavelengths is of substantial interest. We have prepared such low band gap polymers using the donor 12acceptor route, which is based on the concept that the interaction between alternating donors and acceptors results in a compressed band gap. Furthermore, for application in photovoltaic devices, sufficient polymer solubility is required. We have prepared four low band gap conjugated polymers, with a bis(1-cyano-2-thienylvinylene)phenylene base structure, and achieved an excellent solubility by the introduction of long alkoxy and alkyl side chains. The polymers were synthesized via an oxidative polymerization. Their electronic properties were determined from electrochemical and optical measurements, which confirm that they indeed have a low band gap. In the blend of such a low band gap polymer with PCBM, evidence for efficient charge transfer was obtained from PL and EPR measurements. However, bulk heterostructure solar cells made of such blends display only low efficiencies, which is attributed to low charge carrier mobilities
The assessment of grip strength in preschool-aged children with and without unilateral cerebral palsy
No full textPurpose To investigate reliability and validity of two grip strength devices in children with and without unilateral cerebral palsy (uCP) aged 2-6 years. Method We assessed grip strength in 20 pre-school-aged children with predominantly spastic uCP (mean age 4y0 +/- 1y2m) and 20 age-matched children without uCP (mean age 3y11m +/- 1y3m) using the Martin Vigorimeter and MyoGrip to investigate test-retest reliability (intraclass correlation coefficients; ICC), known-group validity (comparative statistics) and convergent validity (correlation analyses) in a cross-sectional design. Results In both groups, test-retest reliability was excellent for both devices and both hands (ICC 0.91-0.97). Grip strength of the non-preferred hand was lower in children with uCP for both devices (p < 0.001). Grip strength was decreased in the non-preferred compared to the preferred hand in children with uCP for both devices (p < 0.001). In children without uCP, grip strength was lower in the non-preferred compared to the preferred hand only for the MyoGrip (p = 0.02). The relation between both devices for both hands was good to very high (r = 0.62-0.92, p < 0.007). Conclusion Both devices can be implemented in clinical practice to assess grip strength in preschool-aged children with uCP. Only the MyoGrip detected differences between both hands in children without uCP and might be more sensitive.The author(s) reported there is no funding associated with the work featured in this article
Reflectie over vrije tijd voor personen met een beperking n.a.v. Demos-onderzoek
No full textOp 9 juni stelden we de resultaten voor van het onderzoek ‘Vrije tijd, in en uit zorg’. Hoe ziet de vrijetijdsbesteding eruit van mensen met een beperking die beroep doen op een zorgvoorziening? Welke betekenissen geven zorgvoorzieningen en vrijetijdsactoren aan vrije tijd voor personen met een beperking? Het exploratief onderzoek van Demos formuleert een antwoord op deze vragen en koppelt er een aantal aanbevelingen aan vast. Onze eigen powerpoint presentatie, alsook die van Joris Van Puyenbroeck en Griet Roets staan online.sponsorship: Vlaamse Gemeenschapscommissie PWO-middelen ter beschikking gesteld door het Vlaams ministerie van Economie, Wetenschap & Innovatiestatus: Publishe

Optical and EPR spectroscopy in pure and blended films of a novel low band gap polymer
No full textEfficient charge transfer between a newly synthesized
low band gap (LBG) conjugated polymer and the C60 derivative
PCBM is demonstrated. Spectral and time-resolved photoluminescence
(PL) measurements show strong quenching and charge separation in
the picosecond time range. The charge transfer is further
confirmed by light-induced electron paramagnetic resonance (EPR)
measurements of both the positive polarons and the fullerene
radicals, which can be resolved in high-frequency EPR. The
potential for the LBG polymer to act as acceptor was examined in
blends with the para-phenylene-vinylene polymer MDMO-PPV. No
charge transfer, but instead energy transfer from MDMO-PPV to LBG
occurs in these blends, as shown by PL spectroscopy
Optimization of morphology of P3HT/PCBM films for organic solar cells: effects of thermal treatments and spin coating solvents
No full textWe demonstrate, by means of light-induced EPR and
optical spectroscopy, that thermal treatment of P3HT/PCBM films
prepared from CB solution results in a decrease of the charge
transfer yields. The improved performance of solar cells is
therefore attributed to optimization of the morphology, in
particular molecular order in the P3HT regions, which could be
monitored by optical absorption and resonant Raman scattering
(RRS). We further found that spin coating from slowly evaporating
solvents leads directly (i.e., without thermal treatment) to
optimal morphologies of the P3HT/PCBM films, with similar results
for charge transfer, morphology and solar cell efficiencies
