In view of the increased prospects of Zn2SnO4 as an alternative photoanode for dye sensitized solar cells (DSSCs), we synthesized phase pure Zn2SnO4 nanostructures by a cost effective sonochemical technique. In order to establish the stability of this alternative photoanode in DSSCs, we further explored the interaction of the synthesized Zn2SnO4 with commonly used photosensitizers in DSSCs, suc...

a new nano-sized lead(ii) coordination polymer, [pb(2-bpdh)(no3)2]n (1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza-2,4-hexadiene)}, was synthesized by a sonochemical method. the structure of 1 may be considered coordination polymer of lead(ii) consist of metallocyclicchains formed by bridging no3- and 2-bpdh ligands. the thermal stability of compound was studied by thermal gravimetric and differen...

High intensity ultrasound can be used for the production of novel materials and provides an unusual route to known materials without bulk high temperatures, high pressures, or long reaction times. Several phenomena are responsible for sonochemistry and specifically the production or modification of nanomaterials during ultrasonic irradiation. The most notable effects are consequences of acousti...

An ultrasonic dental descaling instrument has been characterised using sonochemical techniques. Mapping the emission from luminol solution revealed the distribution of cavitation produced in water around the tips. Hydroxyl radical production rates arising from water sonolysis were measured using terephthalate dosimetry and found to be in the range of mol min -1 , comparable with those from a s...

The sonochemical acceleration of bleaching of Rhodamine B by sodium hypochlorite has been studied using ultrasound intensities in the range 0-7 W cm(-2). Using a 20 kHz ultrasonic horn, it was shown that ultrasound could significantly shorten the treatment time and/or the concentration of hypochlorite required for the reaction. A number of intermediate species formed during the reaction have be...

Metal Organic Framework (MOF) is a material that serves as photocatalyst for decomposing methylene blue pollutant. MOF can be constructed using several kinds of synthetic methods. This study aims to determine the alternative efficient and eco-friendly synthesis method isonicotinic acid-modulated chromium perylene 3,4,9,10-tetracharboxylate (Cr-PTC-HIna) solvothermal, hydrothermal, sonochemical,...

High-frequency ultrasounds have recently gained interest as oxidative technique for sonochemical degradation of organic contaminants in water. In this study an innovative approach applying 200 kHz ultrasounds to improve both sludge anaerobic biodegradability and decontamination is proposed. Digestion tests were performed on batch reactors fed either with untreated or sonicated sludge, at differ...

This review covers sonochemical fabrication of polymer nanocomposites. In addition to its application to the synthesis of various polymeric systems, due to its powerful efficiency, sonochemistry has been widely used not only as the assistant of dispersion for nanomaterials such as carbon nanotubes (CNT) and organophillic clay, but also as a special initiator to enhance polymerization for fabric...

Photochemical internalization (PCI) is a technique that uses the photochemical properties of photodynamic therapy (PDT) for the enhanced delivery of endolysosomal-trapped macromolecules into the cell cytoplasm. The released agent can therefore exert its full biological activity, in contrast to being degraded by lysosomal hydrolases. Activation of photosensitizers via ultrasound (US), called son...

in this investigation, we report facile synthesis of cadmium(ii)-thioacetamide nanocomposites in the presence and absence of polyvinyl alcohol under ultrasonic irradiations, using cadmium acetate dihydrate (cd(ch3coo)2.2h2o), potassium iodide (ki), thioacetamide (taa, ch3csnh2), and polyvinyl alcohol (pva) as the starting materials. results show that in the presence of polyvinyl alcohol size...
