  • Zinc stannate nanostructures (CoE paper receives International attention)
    Producer PR Web TestTime Innovations Report Physorg NanoWerk Taken from http www ait ac th news and events 2011 news nano student2019s article generates numerous news items view Zinc stannate nanostructures growing a highly useful semiconductor Abstract This timely review focuses on the synthesis of zinc stannate zinc tin oxide ZTO nanostructures by the hydrothermal method as well as the physical properties and applications of different zinc stannate nanostructures in solar cells gas sensors and photocatalysts Tsukuba Japan Posted on March 24th 2011 The review is published in March 2011 in the journal Science and Technology of Advanced MaterialsVol 12 2011 p 013004 Itis presented by Sunandan Baruah and Joydeep Dutta from the Asian Institute of Technology Klong Luang Thailand Binary semiconducting oxide nanostructures such as zinc oxide and titanium oxide are widely used in sensors and catalysts However ternary semiconducting oxide nanostructures which show higher electrical conductivity and are more stable than the binary type are increasingly in demand for specific applications due to their particular physical properties In contrast to conventional top down processes involving physically breaking large macroscopic materials into nanoparticles the chemically based self organization approach offers an inexpensive and flexible means of precisely controlling the size crystal structure and optoelectronic properties of semiconducting oxide nanostructures which is crucial for the use of ZTO in specific applications ZTO nanostructures can be produced using a variety of methods including thermal evaporation high temperature calcination mechanical grinding sol gel synthesis hydrothermal reaction and ion exchange reaction Different methods produce different ratios of ZTO oxides and impurities expressed in alternative crystal structures The authors describe the pertinent features of the hydrothermal growth method for synthesizing ZTO including high purity of the stable zinc orthostannate Zn2SnO4 and the accompanying cubic spinel crystal structure Moreover hydrothermal growth is an attractive and

  • Zinc stannate nanostructures (CoE paper receives International attention)
    generates numerous news items A review article coauthored by an AIT doctoral student Mr Sunandan Baruah and AIT s Vice President for Academic Affairs Prof Joydeep Dutta has been featured in leading technology news portals including Research SEA and TMCNet apart from popular news portals like Yahoo News and PRWeb Based on a review article published in the journal Science and Technology of Advanced Materials published by Institute of Physics the article entitled Zinc stannate nanostructures hydrothermal synthesis has formed the basis of various news items While synthesizing zinc stannate we realized that there was a dearth of research material available on this subject and this prompted us to write a review article says Mr Baruah A doctoral student at AIT he has been using zinc oxide for solar cells photocatalysis and gas sensing However zinc oxide nanoparticles tend to dissolve slowly upon exposure to moisture and hence we decided to study ternary oxides like Zinc stannate he reveals We found its performance is comparable with Zinc Oxide but since it has a complex structure it does not dissolve he adds AIT s Center for Excellence in Nanotechnology has already synthesized particle of Zinc Stannate and tested it for photocatalysis and gas sensing Prof Dutta says They have already reported another work using zinc stannates entitled High performance Liquefied Petroleum Gas sensing based on Nanostrcutures of Zinc Oxide and Zinc Stannate in Sensors and Actuators B an Elsevier journal which is in press The article by Mr Baruah and Prof Dutta was published in the March issue of the journal and now forms the basis of numerous news items The original article can be read at this link while the news items can be read at these links NanoTechNow Yahoo News TMC Net All Voices Research SEA Digital Producer PR

    of nano micro macro scaled components and processes While the ultimate vision in nanotechnology may be an entirely bottom up approach to building systems it is unrealistic to expect this to happen anytime in the foreseeable future Only realistic possiblity to achieve tangible results in a reasonable time frame before the stakeholders run out of patience is to use nanomaterials in a hybrid approach that involves a systamatic nano micro macro integration Such an approach will also allow us to utilize the existing infrastructure in the micro area MEMS microelectronics from the last couple of decades which would make economic sense This talk will expand on this theme on product and system development using nanomaterials and nanotechnology Examples will include a carbon nanotube CNT based chemical sensor that has been monitoring air quality in the crew cabin in the Inter nat ional Space Station since January 2009 and under development for security applications a CNT based biosensor for water quality monitoring CNT based X ray tubes for security and other applications supercapacitors and several other developments we have been working on for the last 5 8 years The author thanks all past and present NASA Ames colleagues for their contributions to the application development efforts especially Jing Li Cattien Nguyen and Michael Oye and Prof Jeong Soo Lee at POSTECH Pohang for his contributions to Bio FETS Superparamagnetic Nanoparticles the Universal Tool for Diagnosis and Therapy Prof Heinrich Hofmann Powder Technology Laboratory Institute of Material Science Station 12 Ecole Polytechnique Federale de Lausanne CH 1015 Lausanne Switzerland This e mail address is being protected from spambots You need JavaScript enabled to view it Based on the clinical unmet needs and recent research in biomarkers the main objective of our work is to develop a nanotechnology based novel diagnostic tool for
