Mankind has a fascination with measurement. Down the centuries we have produced a plethora of incompatible and duplicatory systems for measuring everything from the width of an Egyptian pyramid to the concentration of radioactivity near a nuclear reactor and the value of the fine structure constant. With the introduction first of the metric system and of its successor the Systeme International d'Unites (SI), the scientific community has established a standard method of measurement based on only seven core units.

This volume comprises the select peer-reviewed proceedings of the International Conference on Nanotechnology: Opportunities and Challenges (ICNOC22). It aims to provide a comprehensive and broad-spectrum picture of the state-of-the-art research and development in nanomaterials, nanocomposites, nanobiosensors, nanochemistry, renewable energy, nanochemistry in medicine, batteries and supercapacitors, targeted cellular therapies, among others. This volume will be useful for researchers and professionals working in nanotechnology and allied fields.

This book tells the story of how chemists, physicians, and surgeons attempted to end the problem of urinary stones. From the late eighteenth to the early nineteenth centuries, chemists wanted to understand why the body formed urinary, pancreatic, and other bodily stones. Chemical analysis was an exciting new means of understanding these stones and researchers hoped of possibly preventing their formation entirely. Physicians and surgeons also hoped that, with improved chemical analysis, they would eventually identify substances that would reduce the size of stones, leading to their easier...

This thesis addresses research on the design, fabrication, and operation of the first saddle-shaped dipole magnet for particle accelerators using a no-insulation high-temperature superconducting (HTS) magnet technology. Unlike HTS magnets with various geometries used in other applications, saddle-shaped magnets posed unresolved challenges in analysis and fabrication due to their complex shape. This thesis is the first study to systematically classify these issues and propose detailed solutions for each. Scaling up the techniques used in this research could enable the development of dipole...
