A simple multi-directional, multi-port array antenna structure is disclosed that can be used for a variety of applications, including but not limited to direction finding (DF) and beam-forming applications in receive and transmit modes, respectively. The disclosed antenna structure offers unique functionalities in both receive and transmit modes. For DF applications in the receive mode, the back-end of the antenna structure features a power sensing mechanism to monitor the power received at all ports. In the transmit mode, the disclosed antenna structure is used for beamforming applications by providing individual port excitation and using antenna arrays.

Induction-heated vessels, and processes for manufacturing induction-heated vessels and vessel components, are provided. The vessels can include a ceramic outer layer and a conductive heating element, which can be provided as a conductive glaze or coating, a conductive inner layer, or a label comprising a conductive element and an RFID tag, to allow the thermal transfer or conduction of heat from the heated surface directly to the contents of the vessel, while the ceramic outer layer of the vessel insulates the contents of the vessel. Also, systems and methods for heating and controlling induction-heated vessels and for tracking loyalty, use, and/or sales using RFID-enabled induction-heated vessels are provided.

Methods and apparatuses for making nanomaterials are disclosed. The methods involve passing one or more source materials through a high pressure and high temperature chamber with an open throat, and then allowing the reactants to expand into a lower pressure, lower temperature zone. The source material is non-stoichiometric and fuel-rich so that excess un-combusted primary source material can form the nanomaterials. In some cases, the apparatus may be in the form of a modified rocket engine. The methods may be used to make various materials including: carbon nanotubes, boron nitride nanomaterials, titanium dioxide, and any materials that are currently produced by flame synthesis, including but not limited to electrocatalysts. The methods may also be used to make nanomaterials outside the Earth's atmosphere. The methods can include making, coating, or repairing structures in space, such as antennae.
