Research and Development

This section outlines our analytical, process and evaluation capabilities.
Although it highlights Nanocor’s physical resources, undoubtedly our
strongest asset is the team of scientists who specialize in this new material
science. These individuals are committed to making the technology work for
your real-world applications.

Nanomer Characterization:

XRD (X-Ray Diffraction)
X-ray diffraction can be conveniently visualized as a reflection of an X-ray incidental beam by parallel, closely spaced planes of atoms within a crystal. For montmorillonite, it confirms the crystalline structure of the mineral but more importantly, XRD measures the average distance between the nanolayers and their relative stacking order. Hence XRD provides valuable information about the degree of nanoclay dispersion. The interlayer distance and stacking order determine the formation and performance of nanocomposites.


XRF (X-Ray Fluorescence Spectrometry)
When a material is irradiated by an X-ray beam, its constituent atoms are excited. This causes them to emit x-rays known as “fluorescence”. Each element in the sample emits its own unique characteristic fluorescent radiation with an intensity directly related to the concentration of the element in the material. XRF provides an efficient way to determine mineral purity and well as the degree and orientation of surface treatments in Nanomer® nanoclays.


AA (Atomic Absorption Spectroscopy)
AA detects the absorption of light to measure the concentration of gas-phase atoms. In general, samples are dissolved into liquid media, and analyzed by the instrument’s sensors. Concentration measurements are determined from a working curve after calibrating the instrument with standards of known concentration. Nanocor scientists use AA to determine the concentration of various metal elements in the montmorillonite to monitor the base mineral quality and purity, essential factors in controlling nanocomposite formation.


GC-MS (Gas Chromatography-Mass Spectroscopy)
GC-MS separates and determines individual components of an organic mixture. It provides useful information to determine thermal decomposition mechanisms for Nanomer nanoclays under different nanocomposite processing conditions.


FTIR (Fourier Transform Infrared)
FTIR detects the adsorption of infrared radiation by materials. The absorption of infrared radiation by montmorillonite and its surface treatments depends on bond strength (force constants if inter-atomic bonds) in the materials as well as the overall symmetry of the unit cell. FTIR provides unique information about nanoclay structural features as well as interaction between Nanomers and matrix polymers.


TGA (Thermo Gravimetric Analysis)
TGA measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material's thermal stability and composition. TGA is used to determine the thermostability of Nanomer nanoclays under different nanocomposite processing conditions.
