Method of ice formation inhibition for waterfowl decoy application

Номер: US20170022404A1
Автор: Brett Michael Clark
Принадлежит: OUTDOOR SPORTS PRODUCTS LLC

A method for maintaining hunting decoy appearance realism in the presence of ice formation on decoy surfaces, comprising a coating having a chemical composition that, upon application to a hunting decoy surface, inhibits ice formation or accumulation on the decoy surface by reducing the freezing point temperature on the decoy surface to below the ambient temperature. The coating composition may be adjusted to change the freezing point depending on the ambient temperature. The coating is a mixture of propylene glycol and polyethylene glycol in water, the propylene glycol component representing 10-90 volume %, the polyethylene component representing 0-5 volume %, with the balance water. In the presence of the coating, water changes from solid to liquid phase, and remains in the liquid phase in the coating mixture until it is removed through evaporation. The coating removes the optical reflectivity created by ice on the decoy surface by reducing the freezing point temperature of the surface to below that of water for the temperature conditions under which the decoys are used in hunting applications.

ELECTRON SPIN LABELED ICE BINDING COMPOUNDS USED FOR CARRYING PARAMAGNETIC CENTERS FOR DYNAMIC NUCLEAR POLARIZATION

Номер: US20160207962A1
Автор: BA Yong, MAO Yougang
Принадлежит:

Spin labeled ice binding compounds (IBCs) including ice binding proteins (IBPs), also called antifreeze proteins (AFPs) and their analogs are exploited to carry the paramagnetic centers for dynamic nuclear polarization (DNP), for enhancing nuclear magnetic resonance (NMR) signal intensities. Use of spin labeled IBCs to perform DNP exploits the IBCs' ability to homogeneously distribute the paramagnetic centers in frozen water solution at low temperature, leading to high DNP efficiency. Other advantages of using spin labeled IBCs include: (1) ability to cryo-protect biological samples; (2) the relative positions and orientations of the spin labeling groups in an IBC may also be cryo-preserved; (3) positions and orientations of spin labeling groups to an IBC can be selected with great freedom and without technical barrier to making multiple spin labels in an IBC; and (4) water solubilities of spin labeled IBCs are potentially high, enabling use of a solvent that is primarily water for DNP at low temperatures. 1. A modified ice binding compound made by the process of electron spin labeling at least one ice binding compound functional group.2. A modified ice binding compound as in wherein the ice binding compound comprises a protein or its active antifreeze mutant.3. A kit comprising a modified ice binding compound made by the process of electron spin labeling at least one ice binding compound functional group and instructions for using the modified ice binding compound.4.
