Abstract: Simulations of interfacial phenomena are useful to understand and predict the phase-change processes that occur around the interface at various operating conditions. A method is described that simplifies the simulation of interfaces and the transport processes occurring across the interfaces.

Moreover, the method accurately determines the gradient of ? at the interface, which is needed for a proper estimation of the mass transfer at the interface.

Abstract: An approach to printing a nickel precursor ink on a wide range of substrates for electronics and magnetic applications is disclosed. The nickel ink reduces to elemental nickel following heating. The ink was printed using an ultrasonic aerosol printing technique. By sintering the nickel precursor ink in the presence of a homogeneous magnetic field, the reduced nickel complex formed continuously aligned nickel nanofibers axially aligned with the direction of the magnetic field. The fabrication of aligned interlayered nanofiber films provides opportunities to produce structures with enhanced isotropic electrical and magnetic properties. The resistivity of the film was found to be as low as 0.56 m?·cm, and the saturation magnetization was measured to be 30 emu/g, which is comparable to bulk Ni. Magnetic anisotropy was induced with an easy axis along the direction of the applied magnetic field with soft magnetic properties.

Abstract: A wireless server-to-server datacenter network architecture uses wireless links to eliminate the need for power-hungry switching fabric of traditional fat-tree based datacenter networks. The server-to-server wireless datacenter network (S2S-WiDCN) requires Line-of-Sight (LoS) between servers to establish direct communication links. Utilizing this LoS links, a horizontal-first routing algorithm is developed which, will establish fast communication links between any pair of communicating servers in the data center. The wireless links can be realized in millimeter-wave (such as 30, 60, 120 GHz) or THz (such as 300 GHz) frequency bands. The use of antenna-arrays to create beam-steering towards communicating servers is necessary to establish the direct server-to-server links. In the presence of an obstruction such as an IT technician, the LoS between communicating servers may be blocked. To address this issue, an obstruction-aware adaptive routing algorithm for the S2S-WiDCN is proposed.

Abstract: Porous metal coatings are produced by multi-step electrodeposition method involving application of higher current density at lower duration and lower current density for longer durations. During higher current step, the evolved hydrogen bubbles serve as the self-collapsing templates to deposit the metal ions and during lower current density at longer duration step, the coating is applied to improve the bond strength. The multi-step depositions by alternating these steps provides the development of more complex porous structures that can have desired interconnectivity between the pores and have desired morphology, and desired wettability and wickability characteristics, and have a good bond strength between the coated layers as well as coated layers and the base substrate.
