Nanoengineered particulate coatings (NPCs) comprise a multiplicity of particulate hosts that are infused with a nanophase comprising a surfactant and at least one guest. The particulate hosts can be clay particles, the surfactant can be a cationic surfactant, and the guest can be an insect repellant. For example, montmorillonite particles infused with hexadecyl trimethyl ammonium bromide and garlic oil form NPCs that may be used to form an emulsion or suspension for spraying on citrus trees to repel Asian Citrus Psyllid.

Engineered particulate systems for controlled release of pesticides and repellants

A continuous reaction system (CRS) allows a method to prepare quantum dots (QDs) in a continuous manner with high precision. The CRS pumps a plurality of reagent fluids into one or more mixing sites to form a reaction fluid that is carried through a heating chamber at elevated pressures to carry out hydrothermal growth of the QDs. The pumps and heating chamber are controlled with a high precision by employing a detector downstream of the heating chamber to provide a signal that is dependent on the composition and size of the QDs. The signal is provided to a signal processor that provides a signal that control the flow rates and temperature parameters in the system. The QDs produced in this manner are consistent in size and composition and can be of a single semiconductor composition or can be core-shell QDs with a shell semiconductor formed on a core semiconductor.

Process for making precision nanoparticles by hydrothermal flow manufacturing

Colored clay particles are prepared by the absorption of pigments, such as dyes, on the surface of clays. The surface of the clay can be modified with a surfactant such that a dye can be well bound to the particle's surface to avoid leaching of the dye into water. The colored clay particles can be used to deter insects, such as the Asian Citrus Psyllid (ACP), by coating a plant, such as a citrus plant, with the colored clay particles. The reflectance of the visible and ultraviolet light can be altered by the choice of dyes such that the spectrum visible to the insect deters the insect from the plant.

Colored clays for agricultural and other industrial applications

Fullerenes, when irradiated with electromagnetic radiation, generate acoustic waves. A photoacoustic tomography method using a material comprising fullerenes is disclosed that includes irradiating the material with a radiation beam such as a laser. The resultant photoacoustic effect produced by the material is detected by at least one detector. A photoacoustic tomography system using a material comprising fullerenes is also described.

Use of fullerenes in photoacoustic imaging

Multimodal nanoparticles are nanoparticles containing contrast agents for PAT and one or more of luminescence imaging, x-ray imaging, and/or MRI. The multimodal nanoparticles can have a dielectric core comprising an oxide with a metal coating on the core. The particles can be metal speckled. The multimodal nanoparticles can be used for therapeutic purposes such as ablation of tumors or by neutron capture in addition to use as contrast agents for imaging.
