摘要:
The invention provides protein adhesives and methods of making and using such adhesives. One type of protein adhesive described herein contains lignin and ground plant meal or an isolated polypeptide composition obtained from plant biomass. Other types of protein adhesives described herein contain a plant protein composition and either a hydroxyaromatic/aldehyde, urea/aldehyde, or amine/aldehyde component.
摘要:
In seismic survey for icy waters, streamers are towed behind a vessel under the water's surface to avoid ice. GPS readings may not be consistently obtained because the ice prevents a tail buoy with a GPS receiver from trailing from streamer at the surface. Instead, a device tows on the streamer under the water's surface. The streamer's absolute position is tracked by intermittently bringing the towed device toward the surface so GPS readings can be obtained. The streamer's absolute position can then be used in conjunction with compass readings and can correlate various seismic sensor signals obtained along the streamer during the survey. The compass readings can be corrected for declination using declinometer readings, which can be compensated for iron effects from the vessel or other device carrying the declinometer.

A method for passivating a biomaterial surface includes modifying proteinaceous material disposed at the biomaterial surface. The passivation may be effectuated by exposing the biomaterial surface to therapeutic electrical energy in the presence of blood or plasma.

The invention relates to a water soluble film based matrix for collecting blood samples, urine samples, serum samples or any other type of samples extracted from living species; so as to avoid cross infection or spillage of samples during transportation of said samples. These samples can then used for further detection of virus, bacteria, finding new molecules, diagnosing genes or extraction of DNA. Also, said matrix will dissolve during analysis of the sample and thus there will be no disposal problems.
摘要:
The present invention provides methods and compositions that facilitate the identification of structures of a variety of macromolecules. For instance, the present invention provides methods for the selective immobilization of macromolecules in an extended or oriented state. The present invention also provides compositions comprising macromolecules selectively immobilized in extended or oriented states.

The invention provides a method for the controlled assembly of layered silk fibroin coatings using aqueous silk fibroin material. The methods described herein can be used to coat substrates of any material, shape, or size. Importantly, the described methods enable control of the biomaterial surface chemistry, thickness, morphology and structure using layered thin film coatings, or bulk coatings. Furthermore, the methods can be performed in all water and do not require intensive chemical processing enabling controlled entrapment of labile molecules such as, drugs, cytokines, and even cells or viruses to generate functional coatings that can be used in a variety of applications.
