Abstract: The present application relates to boron nitride nanotube (BNNT)-nanoparticle composites, to methods of preparing such composites and their use, for example, in metal/ceramic matrix composites and/or macroscopic assemblies. For example, the methods comprise subjecting a source of hydrogen, a source of boron, a source of nitrogen and a nanoparticle precursor to a stable induction thermal plasma and cooling the reaction mixture to obtain the composite.

Abstract: A process for producing boron nitride nanotubes (BNNTs) involves providing a one or more sources of boron, nitrogen and hydrogen to a stable induction plasma to form a reaction mixture of boron, nitrogen and hydrogen in the plasma, and cooling the reaction mixture to form BNNTs. The process is capable of very efficiently producing small (10 nm or less diameter), reasonably pure BNNTs continuously in high yield at or around atmospheric pressure without the need to use metals as the catalyst. The process may be further modified by providing one or more sources of carbon to produce BNNTs doped with carbon (e.g. BCNNT).

Abstract: Provided is a process and an apparatus for purifying boron nitride nanotube (BNNT) materials. The process involves the use of a halogen gas to remove halogen-reactive impurities from boron nitride nanotube (BNNT) materials in a single step with minimal interactions to produce structurally pristine BNNT. Gaseous byproducts are produced that 5 can be removed without the need for solution phase treatments. Yield efficiencies and purity of recovered BNNT are high compared to the other known methods of purification for BNNT material.

Abstract: The present application discloses methods for preparing superhydrophobic nano-microscale patterned films, films pre-pared from such methods and uses of such films as superhydrophobic coatings. The superhydrophobic nano- microscale patterned films comprise high aspect ratio nanoparticles such as boron nitride nanotubes (BNNTs) and/or carbon nanotubes (CNTs).

Abstract: A value inheritance widget system includes a display device including a user interface, and a value impact engine coupled to the display device. The value impact engine is configured to display at least one widget on a user interface. The widget includes a value. The value comprises an inherited value. The value impact engine is further configured to display information of a scope of inheritance of the value before user interaction with the widget. The information of the scope of inheritance of the value includes a number of inheritance levels of the value and a number of objects impacted by a change to the value. The value impact engine is further configured to receive a user input changing the value of the widget and change the value of the widget and the objects in response to receiving the user input.
