US Classification:

514/691000

Abstract:

Extracts of vetiver oil were found to be significant repellents and toxicants of ants, ticks, and cockroaches. Nootkatone was shown to significantly decrease ant invasion and increase mortality in fire ants. Nootkatone is an effective repellent and toxicant of ants either by itself or as an addition to other substrates, including mulches made from vetiver grass roots, diatomaceous earth, alumina, silica, clays; building materials made from either aluminum or wood; and other suitable solid substances. Nootkatone was also a repellent and toxicant to ticks; and a repellent to cockroaches. Nootkatone is non-toxic to humans and other mammals and is environmentally safe. In addition, it is believed that other extracts of vetiver oil, specifically -cedrene, zizanol and bicyclovetivenol, will be effective against ants, ticks, and cockroaches.

Appl. No.:

13/588941

Inventors:

Yashen Xia - Newton MA, US
Feng Chen - Belmont MA, US

International Classification:

B01J 19/08

US Classification:

204165, 42218604, 42218603

Abstract:

Provided are electronegative-ion-aided methods and apparatus to achieve reduction of carbon dioxide gas into useful products. In one embodiment, using different methods of discharge, the electronegative gases forms non-equilibrium electronegative ions, so that carbon dioxide reduction occurs for the production of organic compounds. When carbon dioxide is introduced into the container containing at least one electronegative gas, such as water, ammonia, bromine or iodine vapor, it reacts to form organic compounds, such as ethanol, methanol, and oxalic acid in the case of water, urea in the case of ammonia, and tetraiodomethane in the case of iodine.

US Classification:

505 1

Abstract:

A method of processing polycrystalline material by performing multi-axis crystal alignment utilizing anisotropies in the crystalline structure including the step of providing a polycrystalline material in a fluid suspension or malleable form having a magnetic moment. An external force to which the material is reactive is applied to align the individual crystals along a first axis. A magnetic field is applied to orient the magnetic moment of the crystals along a second axis, transverse to the first axis. The crystalline material may have a magnetic moment associated with a rare earth element of the material.
