International Classification:

C08L 89/00

US Classification:

1061271, 1061322, 1061481, 1061562

Abstract:

The, present invention provides useful adhesive compositions having similar adhesive properties to conventional UF and PPF resins. The compositions generally include a protein portion and modifying ingredient portion selected from the group consisting of carboxyl-containing compounds, aldehyde-containing compounds, epoxy group-containing compounds, and mixtures thereof. The composition is preferably prepared at a pH level at or near the isoelectric point of the protein. In other preferred forms, the adhesive composition includes a protein portion and a carboxyl-containing group portion.

International Classification:

H04B 1/06

US Classification:

455140, 455 302

Abstract:

An N×M crosspoint switch allows a signal from any one of the N inputs to be routed to one or more of the M crosspoint switch outputs. The switches within the crosspoint switch can be configured as voltage mode or current mode switches. In voltage mode switching an input to the crosspoint switch is provided to an input device, such as an amplifier, having a low output impedance. The output of the low impedance device is provided to a switch that connects the output of the low impedance device to a high input impedance device, such as a band translation device. In current mode switching, the low impedance output of the input device is connected to selectively activated high isolation transconductance devices having high input impedances. The outputs of the transconductance devices are connected to low impedance devices that operate as summing nodes.

US Classification:

428355CP, 106244, 106220, 106250, 427386, 427516, 427508, 428497

Abstract:

Compositions useful for preparing pressure sensitive adhesives, coatings, and/or films are provided, along with methods of making and using the same. The compositions are made from renewable, plant-based materials. The compositions comprise plant oil triglycerides that are polymerized and crosslinked to yield polymer matrices. Plant-based carriers and/or tackifiers can be used in the invention, including epoxidized plant oil triglycerides, acrylated epoxidized plant oil triglycerides, and dihydroxylated plant oil triglycerides. Natural tackifiers such as rosin esters and terpenes can also be used in the compositions. Dihydroxylated plant oil triglyceride tackifiers for use in biobased and synthetic adhesives are also provided.

Abstract:

Nanocatalysts and methods of using the same to obtain aromatic hydrocarbon compounds from a source of carbon atoms and a source of hydrogen atoms in a single reaction step is provided. The catalyst comprises an Fe/FeOnanocatalyst that may be supported on a non-reactive support material such as a zeolite or alumina COand Hare preferred sources of carbon and hydrogen atoms for the reaction. The aromatic hydrocarbon compounds produced are suitable for direct usage as fuel without need for further refining.
