Theoretical studies on the initial reaction kinetics and mechanisms of p-, m- and o-nitrotoluene

Direct bond dissociations of C–NO2 are dominant at high temperatures for p- and m-nitrotolune, while O transfer are predominant at low to intermediate temperatures. For o-nitrotoluene, the H atom migration and C–NO2 bond dissociation are important.

Is Lanthanide-Transition Metal Direct Bond a Route to Achieving New Generation {3d-4f} SMMs?

One of the main challenges in this area of Single Molecule Magnet is quenching quantum tunnelling of magnetization (QTM), which often undercut the magnetization reversal barrier. Among several strategies employed,...

Fabrication of Ceramic Interposers for Module Packaging

In this study, low-temperature cofired ceramic (LTCC) and 3D-printed ceramic interposers are designed and fabricated for a double-sided power electronic module. The interposer acts as electrical insulation between two direct-bond copper (DBC) power substrates as well as mechanical support to evenly distribute the weight of the top DBC substrate onto the entire bottom DBC substrate instead of directly onto the bare power semiconductor die. A novel LTCC fabrication process for 14 layers of green tapes with premachined recesses and holes is developed. A similar interposer is 3D printed using a ceramic resin. Finally, the fabricated LTCC and 3D-printed interposers are compared.
