NIUMAG in the Spotlight | Exploring the Microscopic Mysteries of Geomaterials! Suzhou NIUMAG's Low-Field NMR Technology Showcased at the 19th National Conference on Rock Dynamics

On August 19, the highly anticipated 19th National Symposium on Rock Dynamics officially opened in Xi’an. As a premier academic event in the field of rock mechanics and engineering in China, the conference brought together leading scholars, research experts, and industry pioneers to explore cutting-edge findings, technological challenges, and development trends in rock dynamics.

At this academic gala themed “Unlocking the Value of Rock Science,” Suzhou Niumag Analytical Instrument Co., Ltd. (hereafter “Suzhou Niumag”) made a striking appearance with its low-field Nuclear Magnetic Resonance (NMR) applications in microstructural analysis for rock mechanics—captivating attention across the exhibition floor.

Microscale Focus: Unlocking the Geotechnical Code

The macroscopic mechanical behavior and failure mechanisms of rocks and soils are closely linked to their microscopic pore structures, fluid distributions, and interactions under multi-physics coupling. Traditional methods often fail to non-destructively capture these dynamic, fine-scale characteristics. Suzhou Niumag’s low-field NMR technology offers researchers a powerful “microscopic lens” that enables non-invasive, rapid, and quantitative analysis.

During the event, Suzhou Niumag showcased how its MacroMR and MesoMR NMR analyzers serve as essential tools in core geotechnical research areas:

Cement-Based Material Research

Accurate tracking of cement hydration, pore structure evolution, and water migration/distribution—empowering high-performance concrete and durability studies.

Soil and Ecological Remediation

Quantitative insights into soil porosity, moisture content, and freeze-thaw dynamics—delivering critical data for saline-alkali land improvement and contaminated soil remediation.

Geohazard Prevention

Analyzing how stress impacts pore structure, crack initiation/propagation, and seepage characteristics—providing micro-scale support for landslide and collapse mechanism studies and early warning model development.

“High-Fidelity, Near In-Situ” Dynamic Testing

Faced with the complex coupling of seepage, stress, thermal, and chemical fields in geotechnical systems, Suzhou Niumag has gone beyond static, single-parameter analysis. By driving innovation in hardware-software integration, the company is evolving its NMR platforms into a full multi-physics coupling solution. This enables “high-fidelity, near in-situ” monitoring of how microstructures and macro-properties evolve under coupled conditions—offering real-time, non-destructive insights that simulate deep subsurface conditions, construction-induced disturbances, and environmental changes with high accuracy. The result is more realistic, predictive, and actionable geoscientific data.

Collaborative Innovation for Geotechnical Research

Throughout the event, Suzhou Niumag’s booth attracted significant attention and in-depth discussions with attending experts and scholars. The technical team provided live demonstrations of NMR applications on typical geotechnical samples and presented detailed data analysis. Visitors gained a deeper understanding of the technology’s principles, device performance, and tailored solutions. Experts expressed strong interest in NMR’s potential to unveil the microscopic secrets of geomaterials.

With years of dedication to low-field NMR technology, Suzhou Niumag continues to empower both frontier research and industrial advancement. By helping scientists better “see” the subsurface world, we contribute to safer engineering, environmental protection, and the sustainable use of natural resources.
