Chemistry at the nano-bio interface.
The interface of biology and inorganic materials represents one of the fastest growing and most promising areas of nanotechnology. The fifth issue of JACS Select contains 22 Communications and Articles from 2008 and early 2009 that illustrate the breadth and creative energy of this young field. Although the use of colloidal particles of metals and semiconductors as pigments dates back many cent...
متن کاملSurface Improvement of Halloysite Nanotubes
A novel development on halloysite-polyvinyl alcohol (HNTs-PVA) nanocomposites has been conducted using malonic acid (MA) by crosslinking PVA and HNTs. PVA-MA crosslinking produces smooth surfaces, which play an important role in enhancing the properties of HNTs-PVA nanocomposite. The crystallographic structures of crosslinked HNTs-PVA show almost no change as depicted by the X-ray diffraction (...
متن کاملDry Sintered Metal Coating of Halloysite Nanotubes
Halloysite nanotubes (HNTs) are a naturally-occurring aluminosilicate whose dimensions measure microns in length and tens of nanometers in diameter. Bonding defects between the alumina and silica lead to net negative and positive charges on the exterior and interior lumen, respectively. HNTs have been shown to enhance the material properties of polymer matrices and enable the sustained release ...
متن کاملMultifarious Applications of Halloysite Nanotubes: a Review
Natural tubules Halloysite are unique and versatile material formed by surface weathering of aluminosilicate minerals and comprises of different proportion of aluminum, silicon, hydrogen, and oxygen. It has chemical formula of Al4Si4O10(OH)8 4H2O. Nanotubular geometry of halloysites exhibit nanoscale dimensions. Basically, this tubular arrangement varies with different regions. HNTs have high m...
متن کاملPolyurethane Coatings Reinforced by Halloysite Nanotubes
The pencil hardness of a two-component polyurethane coating was improved by adding halloysite nanotubes to the recipe at a weight fraction of less than 10%. The pencil hardness was around F for the unfilled coating and increased to around 2H upon filling. It was important to silanize the surface of the filler in order to achieve good coupling to the matrix. Sonicating the sample during drying a...
