Applications & Industries

Nuclear Magnetic Resonance (NMR) spectroscopy is an indispensable tool in modern analytical science.

Polymer & Tyre Research

Nuclear Magnetic Resonance (NMR) is an extremely powerful non-invasive technique for the characterization of polymers (or polymer melts) and quality control of related products. In the drug industry polymers are widely used in the formulation and also as an active ingredient. Most of the time conventional chromatographic techniques fail to characterized these polymers owing to their complex structure and dynamics. On the other hand, rubbers and/or tyres are neither solid nor liquid-like. These are soft matter and have considerable molecular dynamics in long-range and in short-range as well as fast local dynamics and slow dynamics like diffusion motions. Both high field and compact low field NMR/MRI are suitable to characterize these motions through different experiments like relaxation measurement, field-cycling experiment and 1H multiple quantum experiments. Specifically for tyre industries, these methods are extremely powerful and environmentally friendly. We are exploring these methods and developing new methods for industrial applications, especially in low field.

Food Chemistry & Quality Control

Food science is defined as “the discipline in which the engineering, biological, and physical sciences are used to study the nature of foods, the causes of deterioration, the principles underlying food processing, and the improvement of foods for the consuming public” by The Institute of Food Technologists. The major problem in present days is food adulteration besides processing and storage of food products and hence accurate and rapid detection methods are required for quality control.

Nuclear Magnetic Resonance (NMR) is an excellent fingerprinting technique and found to be very fruitful quantitatively and qualitatively in processing foods products. Food industries are very diverse in nature and extremely heterogeneous complex systems. NMR methods can be used for both solid, liquid and semi-solid for food products but traditional GC and GC-MS can’t be used for solid samples. Unlike traditional analytical techniques, NMR can be used to detect wide verities of chemical constituents in food samples or in a mixture in a single run by different nuclei like 1H, 13C, 31P and 15N etc.

Here we are interested in many food products like honey, dairy products, wine and meat etc and our goal is to develop fast, efficient and robust methods for food industries.

Batteries Quality Control

NMR is been proven and viable tool to probe the secondary(or multi phase) structure in addition to the water molecule mediated layered structure of cathode materials for batteries. The adequate test, quality of materials and material processing protocols were addressed based on solid state/solution state NMR spectroscopy. The approach simultaneously verified with electro chemical experiments such as Cyclic voltameteric studies, Impedance spectroscopy, and with Battery testing. Aforesaid activity including the detection of impurities, identifying the shock sensensing method and engineering the impurities in cell for the best performance of batteries. A nominal protocol will be set up in order to provide calibrated data through certified methods. A development towards process control and training new personnel will also be entertained.
