With our patent technologies, CNTs products with high quality and high purity have been produced, while the applications are under researching. Now, large scale CNTs with high quality and high purity are on market for global customers.
CNTs are one-dimensional nanomaterial with unique structures (several tens of nanometers in radial dimension, micrometers in axial dimension, closed cap at the two ends of the tubes). CNTs are made of several to several tens of coaxial tubular structures. The distance of adjacent walls are the same, about 0.34nm.

We characterize our MWCNTs by means of:
Transmission electron microscopy (TEM) allowing for the assessment of detailed structures
RAMAN spectroscopy suitable for the quick and reliable screening of the presence of MWCNT
Scanning electron microscopy (SEM) providing overviews of sample structures while less sensitive to sample preparation and homogeneity than TEM
Thermogravimetric analysis (TGA) giving information about relative abundance of catalyst particles, nanotubes and other carbonaceous structures; and
Elemental analysis assessing the contribution of the catalyst particles and hydrocarbons to the total sample mass.

Avian Influenza (H5N1, or Bird Flu) can be a fatal disease in humans and a serious threat to become a pandemic event. Since there is no pharmaceutical remedy for the Bird Flu it is essential that preventive treatments be tested and developed in order to enhance survivor rates in the human population.. ...
香港大学李嘉诚医学院发现，把极微细的“纳米银颗粒”注射进病人体内后，银粒会依附在乙型肝炎病毒上以抑制病毒复制，10分钟内可减少40%病毒，1小时后可使约90%病毒消失. ...
In the quest to pack ever-smaller electronic devices more densely with integrated circuits, nanotechnology researchers keep running up against some unpleasant truths: higher current density induces electromigration and thermomigration, phenomena that damage metal conductors and produce heat, which leads to premature failure of devices. ...
Car batteries as we know them today may soon be relics. Storing energy in clunky containers with limited shelf lives has plagued car makers and military engineers who need lightweight, powerful ...
-- Scientists have fabricated a 'nanopencil' with a tip so small that it can be used as a scanning probe in ultrahigh-density computer data storage systems.
Researchers in Switzerland have developed a new method to fabricate borosilicate glass nanoparticles. Used in microfluidic systems, these "Pyrex"-like nanoparticles are more stable when subjected to temperature ...
