Oxide nanocrystallite aggregates are candidates for use in dye-sensitized solar cells. The aggregates are of submicron size, formed by nano-sized crystallites and, therefore, able to offer both a large specific surface area and desirable size comparable to the wavelength of light. While used for a photoelectrode in a dye-sensitized solar cell, the aggregates can be designed to generate effectiv...

The long-term performance of a submerged membrane fungi reactor was observed while a synthetic textile wastewater containing either or both of the two structurally different azo dyes was continuously fed. Compared to the Acid Orange II dye (simpler structure), higher biosorption but slower biodegradation of the polymeric dye (Poly S119) was observed in sterile batch tests. In the membrane biore...

Delta-lysin is a linear, 26-residue peptide that adopts an alpha-helical, amphipathic structure upon binding to membranes. Delta-lysin preferentially binds to mammalian cell membranes, the outer leaflets of which are enriched in sphingomyelin, cholesterol, and unsaturated phosphatidylcholine. Mixtures including these lipids have been shown to exhibit separation between liquid-disordered (l(d)) ...

Many researchers working on the development of dye-sensitized solar cells (DSCs) continue to focus synthesis photoanode materials with high surface area, along light scattering ability enhance harvesting efficiency (LHE). Meanwhile, dye packing density, which also impacts LHE significantly, is often overlooked. Solvothermally synthesized anatase TiO2 nanoparticles (SANP) were obtained by a new ...

The present study focuses on effects of operational parameters on electrochemical wastewater treatment for synthetic wastewater. Electro-oxidation has emerged as one of the advanced oxidation processes gaining more attention because it offers many distinctive advantages over other conventional methods such as versatility, high treatment efficiency, safety, amenability of automation and cost eff...

We have investigated the physical and optical properties of the left-handed chiral dopant ZLI-811 mixed in a nematic liquid crystal (LC) host BL006. The solubility of ZLI-811 in BL006 at room temperature is ~24 wt%, but can be enhanced by increasing the temperature. Consequently, the photonic band gap of the cholesteric liquid crystal (CLC) mixed with more than 24 wt% chiral dopant ZLI-811 is b...

An advanced stopped-in-loop flow analysis (SILFA) is proposed for the catalytic determinations of vanadium and iron. The chemistry relies on a vanadium- or iron-catalyzed oxidative reaction of p-anisidine by bromate or hydrogen peroxide in the presence of an activator (Tiron or 1,10-phenanthlorine) to form a red dye (510 nm). Reagents for the vanadium- or iron-catalyzed reaction are well mixed ...

Mixed association of calix[4]resorcinarene with ethyl sulfonate groups on the lower rim and dimethylaminomethyl groups on the upper rim (CR) and cationic surfactant 4-aza-1-hexadecyl-azoniabicyclo[2.2.2]octane bromide (DABCO-16) is studied by methods of tensiometry, conductometry, potentiometry and NMR spectroscopy at fixed CR concentration and varied surfactant concentration. Beyond ca. 0.4 mM...

Methyl red, a synthetic azo dye, was reported for not only being mutagenic but also its persistence has severe consequences on human health, such as cancer, alongside detrimental environmental effects. In the present study, Pseudomonas putida OsEnB_HZB_G20 strain isolated from soil sample to study catalytic activity degradation of methyl red dye. Another strain, aeruginosa PA 1_NCHU used an ele...

Co-sensitized solar cells have gained more attention due to the ability of energy conversion process by absorbing photons from wide range spectrum including visible and near-infrared region. TiO2 electrodes were co-sensitized with PbS/CdS core-shell quantum dots N719 dye. PbS/CdS/N719 dye-sensitized fabricated poly(ethylene oxide) based solid polymer electrolyte consisting iodide/triiodide redo...
