• MICRO: Wet Surface Technology
  such as vias, contacts, deep trenches, and poly-Si features, where water spots form easily at hydrophilic/hydrophobic interfaces. Spots that are large enough to overlap more than one die will result in a definite yield loss, and even smaller water spots can cause killer defects, high leakage currents...
• Tableting Process Uses Dry Gelatin, Eliminates Preprocessing Steps
  . "Tableting processes are too complex and some of them, such as wet granulation, are so dirty that they require a significant amount of cleanup time," he says. Dry gelatin is the key to the process, Nguyen says, since its binding, cohesive and hydrophilic properties allow it to function as diluent, binder...
• Here come metal-oxide nanotubes
  discovered in the 1990s. "For example, the materials we're working with are much more hydrophilic than carbon and can load nearly 50% percent of their weight with water," says Sankar Nair, assistant professor in Georgia Tech's School of Chemical and Biomolecular Engineering. "There is a whole range...
• Tuning in to New Solvents
  promising. For example, many enzymatic transformations are inhibited by the limited solubility of most hydrocarbon substrates in aqueous enzymatic solutions. In order to overcome this limitation, we have incorporated a series of hydrophilic organic co-solvents (i.e.,THF, acetonitrile, dioxane...
• Controlled Release Moves Beyond Patent Extension
  with hydrophilic surfaces and hydrophobic interiors that can carry insoluble pharmaceuticals. PR Pharmaceuticals (Fort Collins, Colo.) combines PEGylation with more traditional CR microencapsulation to achieve sustained release plus controlled bioavailability. The company s InsuLAR injected CR insulin product...
• Assure Batch Uniformity for Freeze-Dried Products
  degradation of the API alter the desired secondary, tertiary or quaternary structure of a peptide or protein product allow polymerization, aggregation or denaturation of active ingredients that have both hydrophilic and hydrophobic character. For biopharmaceuticals, conformational changes should...

  and 5000/500 systems specified at 70 nm. The Omega2000 cleaner/rinser/dryer produces particle-neutral hydrophobic or hydrophilic wafers @ 0.16 um using motionless surface tension gradient technology. The system's CleanPoint filter removes particles >=0.065 um from DI water. Mean time between failures is 3000...

• Latest experiences of film coating
  structure and a hydrophilic surface. Too much absorbency leads to binder migration to the base paper and decreases surface strength. The biggest issue in base paper development will be the administration of low viscosity liquid penetration to the inner structure. The coating colour window is smaller...
