Journal ArticleDOI
Photocatalytic Carbon-Nanotube–TiO2 Composites
TL;DR: The literature and advances in photocatalysis based on the combination of titania (TiO2) and carbon nanotubes is presented in this paper, and the proposed mechanisms of catalytic enhancement resulting from the pairing of the titania semiconductor with either metallic, semiconducting, or defect-rich carbon nanotsubes (CNT) is discussed.
Journal ArticleDOI
Novel Powder-Processing Methods for Advanced Ceramics
TL;DR: In this article, the fundamental principles for green body formation are discussed; a distinction is made between physical and chemical gels based on the nature of the induced gelation; and an overview of the properties of dense suspensions is presented, with a focus on the factors controlling the maximum solids loading.
Journal ArticleDOI
Processing and Structure Relationships in Electrospinning of Ceramic Fiber Systems
Wolfgang M. Sigmund,Junhan Yuh,Hyun Jong Park,Vasana Maneeratana,Georgios Pyrgiotakis,Amit Daga,Joshua James Taylor,Juan C. Nino +7 more
TL;DR: In this paper, the experimental and theoretical basis of ceramic e-spinning is reviewed and an expanded electro hydrodynamic (EHD) theory is proposed to predict fired fiber diameter for lanthanum cuprate fibers.
Journal ArticleDOI
Functionalized Multiwall Carbon Nanotube/Gold Nanoparticle Composites
Bumsu Kim,Wolfgang M. Sigmund +1 more
TL;DR: The here found complex formation of positively charged colloidal gold and defect sites on fMWNTs indicates the location of functional groups on carbon nanotubes, and it is suggested that negatively charged colloids such as gold nanoparticles could be used for detection of defect Sites on carbon Nanotubes.
Journal ArticleDOI
Defect chemistry and defect engineering of TiO2-based semiconductors for solar energy conversion
Janusz Nowotny,Mohammad A. Alim,Tadeusz Bak,Mohammad Asri Idris,Mihail Ionescu,Kathryn Prince,Mohd Zainizan Sahdan,Kamaruzzaman Sopian,Mohd Asri Mat Teridi,Wolfgang M. Sigmund +9 more
TL;DR: This tutorial review considers defect chemistry of TiO2 and its solid solutions as well as defect-related properties associated with solar-to-chemical energy conversion, such as Fermi level, bandgap, charge transport and surface active sites.
