About International Journal of Extreme Manufacturing


The International Journal of Extreme Manufacturing (IJEM) publishes original articles and reviews of the highest quality related to the science and technology of manufacturing functional devices and systems with extreme dimensions (extremely large or small) and/or extreme functionalities, ranging from fundamental science to cutting-edge technologies that support the manufacturing of high-performance products involving emerging techniques and breaking the limits of currently known theories, methods, scales, environments, and performance.

Extreme manufacturing is specifically manifested in manufacturing with extremely high energy density, ultrahigh precision, extremely small spatial and temporal scales, extremely intensive fields, and giant systems with extreme complexity and several factors. It involves multidisciplinary fields, including machinery, materials, optics, physics, chemistry, mechanics, and mathematics.

Subjects of interest include but are not limited to, theory, process, metrology, characterization, equipment, conditions, and system integration in extreme manufacturing, as well as materials, structures, and devices with extreme functionalities.
