Removal of Water Contaminants Using Nanotechnology

Yu Z., Li Z., California State Polytechnic University, Pomona, US

Propanil, Diuron, Simazine, and Metolachlor are widely used as herbicides and pesticides in California agriculture and across the U.S., and are considered to pose a significant threat to water contamination by transporting chemicals into surface [...]

Catalytic activity of Cu-CeO2-ZrO2 for biodiesel production

Wongvitvichot W., Jampa S., Luengnaruemitchai A., Chaisuwan T., Wongkasemjit S., Chulalongkorn University, TH

Ceria-Zirconia (CeO2-ZrO2, CZ) was synthesized using two different methods, coprecipitation (copre) and nanocasting (nanocast), for using as support material for copper (Cu) catalyst. Cu-CeO2-ZrO2 (CuCZ) was applied for esterification reaction in biodiesel production. Structure and [...]

Evaluation of the genotoxic potential of different types of nanofibrillated celluloses

Catalán J., Lindberg H.K., Aimonen K.J., Wolff H., Wedin I., Nuopponen M., Savolainen K.M., Norppa H., Finnish Institute of Occupational Health, FI

Nanofibrillar cellulose (NFC) is among the most promising innovations in the forest industry. Due to its unique properties, NFC has a wide variety of possible applica-tions. As NFC consists of thin and long fibres with [...]

Moisture Uptake Characterization in Nanocellulose Using Microwave Cavity

Emiroglu C.D., Natarajan B., Gillman J.W., Liddle J.A., Obrzut J., National Institute of Standards and Technology, US

Nanocellulose has been a continuously emerging area of interest over the recent years due to inexpensive, abundant, and renewable nature of the material source. Cellulose nanocrystals (CNCs) are regarded to be highly useful candidates as [...]

Binder applications of cellulose nanofibrils: new developments

Tajvidi M., Leng W., Hunt J.F., Diop C., Bousfield D., Gardner D., Amini E., Bilodeau M., Gramlich W., Laboratory of Renewable Nanomaterials, University of Maine, US

A key path towards the commercialization of cellulose nanomaterials is to target large-volume applications in commodity products where a successful market introduction could potentially mobilize orchestrated efforts to revitalize the forest products industry. At the [...]

Preparation, Characterization and Application of Nanocellulose

Volkert B., Hettrich K., Fischer S., Fraunhofer Institute for Applied Polymer Research IAP, DE

Novel spherical nano-scaled cellulose particles have been prepared by high-pressure homogenizing of four different types of pre-treated cellulose samples with MICROFLUIDIZER™ processor (MF) in aqueous media. One possibility of pre-treatment is a decrystallization step realized [...]

Sustainable Technology Solutions – Natural rubber to replace plasticized PVC in exterior durable application – A case study by NZ Product Accelerator model of engagement of supply chain partners

De Silva K.K.G., Taylor M., Nilmini R., Kariyawasm S., Vithanachchi J., NZ Product Accelerator - University of Auckland, NZ

Rigid PVC is flexibilized by the addition of plasticizers such as phthalates to obtain the properties of elastomers. These plasticizers in the polymer matrix are not covalently bound to the main polymer chain, which makes [...]

Nanodielectrics for use in HVDC power systems and their structure-property relationships using Chemometric methods

Stevens G.C., Freebody N.A., Vaughan A.S., Perrot F., Gnosys Global, UK

There is a need to develop materials with controlled electrical resistivity, reduced space charge accumulation, higher thermal conductivity, higher dielectric strength, enhanced voltage endurance and surface discharging erosion resistance to cope with DC stresses in [...]
