The present work deals with the development of new catalysts, transition metal phosphides, which have outstanding activity for hydrodeoxygenation of pyrolysis oil. The study is significant as it leads to the production of high-energy content [...]

Synthesis and characterization of magnetic manganese ferrites using a simple combustion method and its application in removal of organics

Desai I., Mills M., Nadagouda M., Elovitz M., Boulanger B., U.S. Environmental Protection Agency, US

Ferrospinels have been shown to have promising oxidative and catalytic properties. Our research focuses on novel magnetic manganese ferrite catalysts which have been developed and thoroughly characterized. Their potential application as oxidative catalysts/sorption in removal [...]

Magnetically Recyclable Nanocatalysts: Eco-friendly Solutions for Green Catalysis

Pereira C., Rocha M., Fernandes C., Rebelo S.L.H., Freire C., Porto University, PT

In the last decades, the global concern for environment protection boosted the development of cost-effective eco-friendly catalytic processes. Magnetic nanoparticles emerged as a new generation of catalysts or catalyst supports owing to their nanosize, easy [...]

Nano-Organocatalysts: new magnetically retrievable tools for enantioselective synthesis

Nehlig E., Motte L., Guénin E., Université Paris, FR

We report the elaboration of new organocatalyst functionalized superparamagnetic iron oxide nanoparticles that can act as a new enantioselective organocatalyst. Differents organocatalysts are grafted using two different methodologies on a nanoplateform constituted of 10 nm [...]

Life Cycle Analysis of Plastics in Southeast Queensland – Recycled Plastics versus Bio plastics in Electronics

Neeli M., Okine M., Thiel D.V., Griffith University, AU

Quinaldine and Indole based pH Sensitive Colorimetric Chemosensor and their application of nanofiber

Bae J.S., Kim S-H, Son D.H. Lee Y-A., Kyungpook National University, KR

Colorimetric chemosensors are now considered as one of the most effective analytical method used in the environment monitoring. Colorimetric chemosensors for pH sensing can easily detect the primary danger or change of the surrounding environment [...]

Photocatalytic Performance of Ag modified and doped TiO2 nanoparticles

Cho C-P, Chang L.-H., National Chi-Nan University, TW

In this work, TBOT was used as the titanium source for preparation of TiO2 nanoparticles, followed by calcination at 500°C for 2 hours to achieve fine TiO2 nanoparticles powder (S1). The obtained S1 powder was [...]

Electrospinning of decorated nanofibers with active cerium oxide nanoparticles
