Methods and compositions are disclosed for controlled addition of components that decrease the viscosity of the viscoelastic surfactant fluids or for controlled changes in the electrolyte concentration or composition of the viscoelastic surfactant fluids. One aspect of the invention relates to the use of internal breakers with a delayed activation. Another aspect of the invention relates to the use of precursors that release a breaking system such as alcohol by a process such as melting, slow dissolution, reaction with a compound present in the fluid or added to the fluid during or after the step of injecting, rupture of an encapsulating coating and de-adsorption of a breaking agent absorbed into solid particles. In another aspect of the invention, alcohols are included in a pad to reduce the low-shear viscosity and reduce the resistance to flow of the treatment fluids during a desired phase of the treatment.

The invention provides a process for preparing a dried modified whey protein concentrate. A whey protein solution is used having less than 5% total solids and a combined calcium and magnesium concentration of less than 70 mmol/kg on a dry basis and a pH of 6.0-7.5. It is heated to greater than 70° C. for up to 60 minutes to denature the whey protein. The solution is then cooled to 40° C.-60° C.; and subsequently spray dried. Alternatively a higher initial concentration of total solids may be used in an embodiment where the heating is carried out on a scraped surface heat exchanger.

The present invention relates to a method for producing a part (108, 200, 300), comprising the following steps:

  • b) introducing at least one recess (103, 203, 303) into the support material (102, 202, 302),
  • c) filling the recess (103, 203, 303) with a construction material (104, 204, 304),
  • d) applying a further layer of support material (102, 202, 302),
  • e) repeating steps b) through d) until completion of the part (108, 200, 300), and
  • f) removing the support material (102, 202, 302).

This method is to provide a manufacturing method and a device that combine the advantages of the layerwise construction (rapid prototyping) with the advantages of machining (e.g. high-speed cutting) and particularly permit the production of sharp-edged contours.

Furthermore, the present invention relates to a device for carrying out the method.

The present invention is directed to new methods for combining, processing, and modifying existing materials, resulting in novel products with enhanced mechanical, electrical and electronic properties. The present invention provides for polymer/carbon nanotube composites with increased strength and toughness; beneficial for lighter and/or stronger structural components for terrestrial and aerospace applications, electrically and thermally conductive polymer composites, and electrostatic dissipative materials. Such composites rely on a molecular interpenetration between entangled single-wall carbon nanotubes (SWNTs) and cross-linked polymers to a degree not possible with previous processes.
