Small Angle X-Ray and Neutron Scattering with Applications to Geomaterials provides techniques for the analysis of geomaterials, which is of great significance for humans because geomaterials are related to earthquake, resource development, underground spaces, carbon dioxide storage, and more. The book introduces the fundamental theory of small angle X-ray and neutron scattering and covers pore accessibility characterization for natural rocks from four aspects, including quantitative evaluation of pore structure heterogeneity and anisotropy, quantification of pore modification in coals due to pulverization, estimation and modeling of coal pore accessibility, and nanoscale coal deformation and alteration of porosity and pore orientation under uniaxial compression.

Finally, interactions between pore structures and fluid behaviors in geomaterials are introduced, along with the connections between small-angle scattering and other techniques (NMR cytophotometry, Transmission Electron Microscopy and synchrotron radiation SAXS and nano-CT) described.

Covers both theory and applications of small angle X-ray and neutron scattering as related to geomaterials Provides context for using the techniques described in the book in connection with other well-known techniques Includes analysis methods of interactions between pore structures and fluid behaviors in geomaterials

The 20th North American Mine Ventilation Symposium (NAMVS 2025) convened in Southpointe near Pittsburgh, Pennsylvania between June 21–26, 2025. It represents a significant milestone in a series that has, since 1982, provided an authoritative forum for advancing the science and engineering of mine ventilation. Over four decades, NAMVS has become an essential platform for disseminating research, fostering professional exchange, and shaping practice in underground environmental control.The proceedings of this twentieth symposium present rigorously peer-reviewed papers covering both established and emerging areas of ventilation. Technical sections address numerical modeling and simulation, diesel emissions and air quality control, ventilation monitoring and automation, mine fans and airflow equipment, coal and nonmetal mine ventilation, mine gases and dusts, planning and design, gob ventilation and methane management, heat and humidity, and mine fires. Collectively, these contributions illustrate the breadth of contemporary challenges and innovations influencing ventilation science and practice.With emphasis on worker health and safety, energy efficiency, and climate-adaptive technologies, this book underscores the role of ventilation engineering in enabling sustainable mineral resource development. It will serve as a comprehensive reference for researchers, educators, practitioners, and policymakers engaged in ensuring safe and efficient underground mining operations.
