    Abstract: Embodiments generally disclosed herein relate to a sub-wavelength multi-port codesign approach between the unit transceiver element and the integrated EM interface to enable a generalized broadband MIMO array with individually programmable element patterns. The co-design approach allows processing of radiated signals at the antenna level distinct from classical arrays. The transmitter and receiver architectures with the integrated EM interface are implemented in 65-nm CMOS and have a bandwidth of 37-73 GHz. Wireless links with data rates up to 12 Gb/s are demonstrated across the spectrum with a wide range of reconfigurability of the active EM interface. The multifunctional EM interface and the broadband transceivers can enable future efficient and compact MIMO arrays for reliable links exploiting frequency, spatial, pattern and polarization diversities.

    Abstract: Methods for forming a coating over a surface are disclosed. A method includes directing a first source of barrier film material toward a substrate in a first direction at an angle θ relative to the substrate, wherein θ is greater than about 0° and less than about 85°. Additionally, a method of depositing a barrier film over a substrate includes directing a plurality of N sources of barrier film material toward a substrate, each source being directed at an angle θN relative to the substrate, wherein for each θN, θ is greater than about 0° and less than about 180°. For at least a first of the θN, θN is greater than about 0° and less than about 85°, and for at least a second of the θN, θN is greater than about 95° and less than about 180°.

    Abstract: In one aspect, oxidant is employed for enhancing Feammox activity. Briefly, a medium comprises an ammonium containing contaminant, an iron component, an oxidant, and a Feammox bacterium and/or enzyme thereof capable of oxidizing ammonium with reduction of Fe(II) to Fe(III), wherein the oxidant regenerates Fe(III) via Fe(II) oxidation. In some embodiments, the medium is soil and/or water.
