Cooling A. nidulans or P. cruentum from 26 °C to 4 °C results in progressive spectral changes. The most significant changes are increases in absorbance at 690 nm (photosystem II), 678 nm (antenna chlorophyll), 625 nm (phycocyanin), and 505 nm (electrochromic band). In the case of P. cruentum there are also increases in absorbance at 568 and 545 nm (B-phycoerythrin) and a decrease at 587 nm. The...

Three copolymers of N-vinylcarbazole and N-phenyl-2-(5’-vinyl-2’-thienyl)-5-(2”-thienyl)pyrrole were synthesized using different feed stock ratios identical to the mass blends and characterized. Blends of poly(N-vinylcarbazole) (PVK) and poly(N-phenyl-2-(2’-thienyl)-5(5’’-vinyl-2’’-thienyl)pyrrole) (PSNPhS) with similar compositions were prepared. Solidstate devices were fabricated, and the ele...

We demonstrate that a three dimensional (3D) crystalline tungsten trioxide (WO(3)) nanoporous network, directly grown on a transparent conductive oxide (TCO) substrate, is a suitable working electrode material for high performance electrochromic devices. This nanostructure, with achievable thicknesses of up to 2 μm, is prepared at room temperature by the electrochemical anodization of a RF-sput...

N,N’-Bis(4-diphenylaminophenyl)pyromellitimide (TPA-PMDI) was synthesized from the condensation reaction of 4-aminotriphenylamine with pyromellitic dianhydride (PMDA). The triphenylamine-diimide TPA-PMDI could be electrochemically polymerized into ambipolar, redox-active polyimide films on the electrode surface in an electrolyte solution via the coupling reactions between triphenylamine radical...

Herein, we report honeycomb nanostructured single crystalline hexagonal WO(3) (h-WO(3)) thin films in order to improve electrochromic performance. In the present investigation, honeycomb nanostructured WO(3) with different unit size and nanowire array with highly nanocrystalline frameworks have been synthesized via a hydrothermal technique. The influence of hydrothermal reaction time on the hon...

Most of the literature accepts, despite many controversial results, that during oxidation/reduction films of conducting polymers (CPs) move from electronic conductors to insulators. Thus, engineers and device's designers are forced to use metallic supports to reoxidize the material for reversible device work. Electrochromic front experiments appear as main visual support of the claimed insulati...

Stimuli-responsive (such as voltage and/or light) fluorescence display systems have attracted particular attention in their promising fields of application. However, there are few examples of self-powered fluorescence display devices. Here we designed and fabricated a self-powered fluorescence display device based on a fast-charging/recharging battery. The specially designed battery was compose...

N,N'-dicyclohexylcarbodiimide (DCCD) has been reported to inhibit steady-state proton translocation by cytochrome bc(1) and b(6)f complexes without significantly altering the rate of electron transport, a process referred to as decoupling. In chromatophores of the purple bacterium Rhodobacter sphaeroides, this has been associated with the specific labeling of a surface-exposed aspartate-187 of ...

Water-soluble sulfonated monomer based on 3,4-propylenedioxythiophene (ProDOT-sultone) was synthesized and characterized for the first time via the O-alkylation of the corresponding unreactive , -disubstituted hydroxyl group with propane sultone in the presence of a catalytic amount of 1,4-diazabicyclo[2.2.2]octane (DABCO). This new monomer was oxidatively polymerized to produce regioregular wa...
