  • 'Plug-and-Play' Weight Reduction Solution by Hollow Glass Microspheres
    . They are tiny hollow spheres and are virtually inert. These glass bubbles (GB) are compatible with. most polymers. Until recently, their use with thermoplastic polymers has been limited because of high rates of bubble breakage from. the high shear forces that they are exposed to during
  • Medical Device Link .
    . As the silica is introduced to the solution, a reaction occurs and the mixture creates hollow spheres. The process takes place in water, and any chemical or drug that is suspended in the water will get trapped inside the hollow spheres when they form. The researchers plan to use the microcapsule
  • Improving Control of the Extrusion Spheronization Process
    eventually causes the dumbbell to break into two spherical particles, with a flat side having a hollow cavity (see 7-1d). Continued action in the spheronizer causes the particles to round off into spheres (see 7-1e). When the sphere is fractured, a hollow particle is revealed. The exact mechanism
  • Spray Drying Manual
    of. evaporation falls rapidly during the second phase. Different products have differing evaporation and. particle-forming characteristics. Some expand,. others contract, fracture or disintegrate. The resulting particles may be relatively uniform. hollow spheres, or porous and irregularly shaped. 1.4.5
  • 3-D Observation of Materials with Hitachi's HD-2000
    to reconstruct the image stack. This type of application can be accomplished in STEM, with a smaller angular range, while still providing useful 3-dimensional information for image analysis. Below a sample of 5 nm hollow palladium particles on a 200 nm amorphous silica sphere was tilted through approximately
  • A new buckyball bounces into town
    graphite rods, turning them to soot. Nanomaterials are extracted from this soot. Buckminster fullerenes such as C are hollow molecules made of interlocking pentagons and hexagons of carbon atoms. They were discovered in 1985 after being produced in a lab and got their name for their resemblance to R
  • Medical Device Link .
    there efficient sensors that could collect these signals and record the information.". A hollow dielectric sphere is imaged using T-ray CT. The sphere was scanned with a 1-mm step size and a terahertz image obtained for 18 projection angles. Recently, however, researchers at Rensselaer became the first
  • Protein-Like Molecules could Form Medical Devices, Electronics
    the soft, tangled filaments to maintain a shape that suits needed applications. The molecule is shaped like a sphere, supported by branching beams of polymer inside, with hollow portions that could theoretically hold drugs or other chemicals. Parquette described his work September 23 at the BioMEMS
