Expert Reviews

Dr. Nicholaos G. Demas, (Newcastle University School Of Machanical & Systems Engg. UK)

Halloysite Clay Nanotubes: Nanoclays are nanoparticles of layered mineral silicates.  Depending on chemical composition and nanoparticle morphology, nanoclays are organized into several classes such as Montmorillonite, Bentonite, Kaolinite, Hectorite, and Halloysite. Clay minerals are hydrous silicates and may simply be described as fine-grained particles with sheet like structure stacked over one another.

Dr. Myron Rubenstein, Ph.D, (Polytechnic University of Turin, Italy)

Halloysite Clay Nanotubes: Nanoclay is used in ink formulation. It helps to adjust the consistency of printing inks to the desired value, avoiding pigment sedimentation, providing good colour distribution, obtaining desired film thickness etc. by incorporation of small amount of organically modified layered silicate. The performance of cosmetics is enhanced by use of nanoclay and they allows good colour renention for lipsticks, eye shadows and nail lacquers.

Dr. Lounis Madani, (University of Abou Bekr Belka)

Halloysite Clay Nanotubes: The nanometer sized Montmorillonite clay particles can improve surface integrity and provide advantages in the mechanical and thermal properties of the composites. The interaction between nanoclay and surrounding matrix even though high tensile strength and modulus were obtained.

Dr. Eric Lin, Ph.D, (Sukhothai Thammathirat Open University (STOU) Nonthaburi,Thailand)

Halloysite Clay Nanotubes: The use of nanoclays in water waste treatment has become common in industry today. Nanoclay exhibit a synergistic effect with many commonly utilized water treatment unit processes  including granular activated charcoal, reverse osmosis and air strippers. Granular activated carbon is particularly effective at removing a large range of organic molecules from water. Nanoclay have proven to be the technology of choice for treating oily wastewaters.

Dr. Robert Wing, Jr., (University of British Columbia, Canada)

Halloysite Clay Nanotubes: Nanoclay as drug vehicle Nanoclay as drug vehicle for controlled release of drug is one of the born age area in medical application, nanoclay have great potential as compared to polymer and carbon nano tubes for drug delivery applications.
