20110159250 | PATTERNING METHOD - The invention provides a method of patterning flowable material on a surface. The method comprises providing the surface with at least one channel and at least one deposition region connected to the at least one channel, the width of the channel being less than the width of the deposition region, and depositing flowable material in the deposition region such that when the material makes contact with the channel the material is directed into said channel by capillary forces, the receding contact angle of the flowable material in the deposition region being less than 30°. | 06-30-2011 |
20120046407 | METHOD OF PREPARING STIMULUS-RESPONSIVE POLYMERIC PARTICLES - A method of making a polymeric compound, comprising discrete particles responsive to an external stimulus, that is resistant to aggregation in high-shear fields, which includes the addition of a polymerization initiator to a reaction mixture comprising a monomer corresponding to the polymeric compound, wherein the method comprises the portion-wise addition of aliquots of a cross-linking agent to the reaction mixture, wherein an aliquot of the cross-linking agent is added to the reaction mixture both before the addition of the polymerization initiator and after the polymerization has progressed substantially to completion. The polymer particles are largely immune to the effects of transient shear rates at least as high as 10 | 02-23-2012 |
20120075389 | DROPLET GENERATOR - A method and device for passively periodically perturbing the flow field within a microfluidic device to cause regular droplet formation at high speed. | 03-29-2012 |
20120273273 | ANALYSIS OF DRILLING CUTTINGS FOR PERMITTIVITY - Systems and methods for analysis of drilling cuttings are described. Complex permittivity is measured of rock cutting samples obtained during drilling operations. The origin of the cuttings is known by flow rate analysis in the drilling system. Various means can be used for rock cutting dielectric measurement. For example, the dielectric measurement can be made by matching the unknown permittivity of the medium to be analyzed to the permittivity of known liquid mixtures by successive saturation and looking for a “zero-contrast” measurement. | 11-01-2012 |
