Physically based fluid simulation can provide realism , but simulating water turbulence remains challenging. Recently, there have been much work on gas turbulence, but these algorithms mostly rely on the Kolmogorov theory which is not directly applicable to water turbulence simulation. This paper presents a novel technique for simulating water turbulence.(More)
We investigated the electrical stabilities of two types of pentacene-based organic thin-film transistors (OTFTs) with two different polymeric dielectrics: polystyrene (PS) and poly(4-vinyl phenol) (PVP), in terms of the interfacial charge depletion. Under a short-term bias stress condition, the OTFT with the PVP layer showed a substantial increase in the(More)
We present the underlying mechanism for the mobility enhancement in a pentacene thin-film transistor ͑TFT͒ with a photocrosslinking polymeric insulator, poly͑vinyl cinnamate͒ ͑PVCi͒. Experimental results for the optical anisotropy, x-ray diffraction, and microscopic layer-by-layer coverage of the pentacene film on the photocrosslinked PVCi layer, exposed to(More)
We investigated the electrical and mechanical stability of flexible 6,13-bis (triisopropylsilylehtynyl)pentacene (TIPS-pentacene) thin-film transistors (TFTs) that were fabricated on polyimide (PI) substrates using cross-linked poly(4-vinylphenol) (c-PVP) and c-PVP/yttrium oxide (Y 2 O 3) nanocomposite films as gate insulators. Compared with the electrical(More)
We demonstrate the first-ever surface modification of green CdSe/ZnS quantum dots (QDs) using bromide anions (Br(-)) in cetyl trimethylammonium bromide (CTAB). The Br(-) ions reduced the interparticle spacing between the QDs and induced an effective charge balance in QD light-emitting devices (QLEDs). The fabricated QLEDs exhibited efficient charge(More)
