Abstract: An impact test apparatus can be used to determine particle interfacial energies with varying relative air humidity. It was observed that capillary condensation increased the adhesive forces of hydrophilic materials. A systems humidity separation window was identified and the differences in interfacial energy for a hydrophilic surface and for a hydrophobic surface can be exploited in order to achieve the separation of particles. Separation and concentration of particles, particularly particles within a mineral ore body, can be obtained.

Abstract: The present invention relates generally to using upconverting inks for producing highly-resolved patterns for inter alia, security applications. More specifically, the present invention relates to the use of sols (inks) and printing processes that produce well-defined printed features consisting of polymers impregnated with luminescent upconversion nanocrystals. The patterns printed using such inks and processes may exhibit defined shapes, characters of text, and various other types of images.

Abstract: Treatment compositions for controlling bed bugs and methods of use, including reducing bed bug resistance to a biological control agent are disclosed. The treatment compositions can include both a NF-kB signaling inhibitor and biological control agent, such as, an entomopathogenic bacteria, to improve the treatment composition efficacy against bed bugs. Provisioning of a small molecule inhibitor of NF-kB signaling can increase the rate of bed bug mortality during infection with a bacterial entomopathogen. Increased mortality can be independent of direct effects of the inhibitor on bacterial growth and can be instead the result of a reduced ability of bed bugs to clear the infection when treated with the inhibitor.

Abstract: Described herein are optoelectronic devices and methods incorporating strain balanced direct bandgap AlxIn1-xP multiple quantum wells. The described devices are strain balanced in that the net strain between the ordered quantum wells and barriers is low, or in some cases zero. Advantageously, the described devices may be specifically designed for higher efficiency than existing AlxIn1-xP and may be grown on commercially available GaAs substrates.

Abstract: An engine oil additive includes carbon nanotubes and boron nitride particulates dispersed within a fluid. The additive is configured to be mixed with a quantity of oil such that the quantity of oil has a concentration from 0.05 to 0.5 grams of carbon nanotubes and of boron nitride particulates per quart of oil to improve the lubricity of the oil. The additive improves the horsepower and torque of the engine while reducing fuel consumption. The carbon nanotubes have an —OH functionalized exterior surface. The carbon nanotubes have a diameter from 1 nanometer to 50 nanometers and have a length from 1 micron to 1000 microns. The boron nitride particulates are hex-boron nitride structures having an average size from 30 nanometers to 500 nanometers.
