Revolutionising Energy and Materials Development Through Nuclear Magnetic Resonance Techniques
Nuclear magnetic resonance (NMR) technology developed over eighty years ago is demonstrating significant untapped potential to revolutionise major industrial sectors. Researchers at the National Laboratory of the Rockies in the United States emphasise that while commonly employed in chemistry NMR can be pivotal in advancing batteries semiconductors bioplastics and biofuels.
Laboratory director Bennett Addison highlights the challenge faced when sourcing new materials by asking Are they truly what they appear to be Small impurities or structural defects at atomic scales often go unnoticed yet can drastically influence the performance of semiconductors polymers or synthetic fibres.
Despite its widespread use for chemical composition verification Addison asserts that the full capabilities of NMR remain largely unexplored. Advances in less-known methods allow NMR to examine solids gels polymers biomaterials and even battery components with an unprecedented level of detail that surpasses traditional techniques.
One notable example involves scientist Ross Kerner specialised in hybrid halide semiconductors. By applying high-sensitivity NMR techniques to analyse industrially produced thin films he uncovered previously undetected impurities. Quantitative data from these analyses enabled several manufacturers to refine their processes leading to improved material quality within days. These findings have been published in esteemed scientific journals such as Nature and ACS Applied Energy Materials.
Such cases reveal that many firms have yet to fully harness the potential of advanced analytical tools like NMR. As supply chains grow more complex precisely identifying material compositions becomes essential to maintaining quality and competitiveness in the industry.
In addition to electronics NMR plays a crucial role in the bioeconomy. Researchers have used solid-state NMR and carbon-13 isotope enrichment to construct detailed molecular models of Poplar tree cell walls critical for biofuel and biomaterial production. These models facilitate computer simulations that accelerate process development for biomass conversion into fuels fertilisers and speciality chemicals.
Furthermore large-scale NMR screening of thousands of plant samples enables the real-time analysis of genetic variation in sugar and lignin content. This approach supports the selection of tree species with optimised biomass traits for energy production enhancing sustainability and efficiency.
Innovative applications extend to bioplastic development where NMR with magic-angle spinning allows high-resolution characterisation of complex structures in semi-solid materials without dissolution. This technique has supported the creation of biodegradable elastomers with potential uses in adhesives robotics and electronics promoting the development of sustainable high-performance materials.
In the field of energy storage lithium-7 NMR has been used to study ion movement within solid electrolytes at various temperatures. These insights help understand how structural disorder enhances ion diffusion directly impacting battery conductivity and efficiency.
According to Addison the greatest challenge lies in the cultural adoption of these advanced techniques as many scientists remain unfamiliar with NMRs full potential. Encouraging wider understanding and application of these methods can drive breakthroughs in material innovation essential for industrial decarbonisation and sustainable development.
Currently over 120 researchers regularly operate NMR spectrometers at the laboratory with numerous companies seeking to optimise manufacturing processes. While basic NMR procedures can be learnt quickly interpreting complex data demands solid training in chemistry and physics. Embracing this technology offers a pathway to significant scientific and industrial progress best achieved by cultivating scientific curiosity and ongoing innovation.
