The ultimate frontier in nanomaterials engineering is to realize their composition control with atomic scale precision to enable fabrication of nanoparticles with desirable size, shape and surface properties. Such control becomes even more useful when growing hybrid nanocrystals designed to integrate multiple functionalities. Here we report achieving such(More)
— Interposers that support high input/output density are becoming critical for system miniaturization and high performance. Silicon and glass are emerging as the primary candidates for such high-density interposers, due to their outstanding dimensional stability, which enables layer-to-layer wiring with small vias. However, silicon and glass have very low(More)
Meeting the high demand for lanthanide-doped luminescent nanocrystals across a broad range of fields hinges upon the development of a robust synthetic protocol that provides rapid, just-in-time nanocrystal preparation. However, to date, almost all lanthanide-doped luminescent nanomaterials have relied on direct synthesis requiring stringent controls over(More)
— This paper reports compliant microwire copper arrays, in thin polymer carriers, as an innovative approach for direct surface mount technology (SMT) attach of large silicon, glass, and low coefficient of thermal expansion organic interposers to printed wiring boards (PWBs). The microwire arrays (MWAs) are prefabricated as free-standing ultrathin carriers(More)
This paper demonstrates a new method in manufacturing micropillars with a relative high depth-to-width ratio, compared with former works. As is known that micropillars enjoy a wide range of applications in the field of biology and chemistry, such as cancer drug screening, the auto-formation of artificial vessels, and so forth, the strict demand for high(More)
