Abstract: An exemplary sample collection swab comprises: a rod comprising one or more protrusions over a distal segment of the rod; and an absorbent material at least partially coating the distal segment of the rod. In some embodiments, the one or more protrusions comprise a raised helical thread.

Abstract: Described herein are microplates having wells with ultra-thin walls and methods of forming thereof. The microplates can be made by thermoforming processes that use ultrasound, electricity, etc., to heat a thin polymer sheet or film prior to molding. Vacuum can be optionally applied to help form or shape the wells.

Abstract: Described herein are injection molded containers and methods for in-mold labeling of the containers. More specifically, injection molded laboratory or medical containers such as centrifuge tubes, cryogenic tubes, blood collection tubes, sample holding tubes, and sample storage tubes, and methods for their mass production with in-mold labels is described.

Abstract: A series of MOF-based hierarchical porous material, namely IPD-mesoMOF-1˜9, based on nanoscale MOFs of MIL-100(Al, Fe, Cr, Sc and In), MIL-53(Al), HKUST-1, DUT-5, DUT-4, MIL-101(Cr), MIL-101NDC(Cr), MIL-101BPDC(Cr) and MIL-110 respectively, forming the permanent interparticle porosities by using close (or relatively close) packing, and preparation methods thereof. Modulated or functionalized IPD-mesoMOFs can be applied for gas adsorption and molecule separation (such as CH4- and CO2-adsorption, gasoline/diesel desulfurization and purification), catalyst loadings and molecular recognition/immobilization of biological macromolecules and enzymes.

Abstract: A two-level Internet search service system. Within the platform of the two-level Internet search service system, Web site builders or Webmasters will have better control on correctly presenting indexes of their contents; Web users will have better control to clarify what they are looking for, can give feedback on service improvement, and can give their opinion for which Web site is more relevant to their query. In the two-level Internet search service system the searches are distinguished into search service provider (SSP) level and in-site level. The objective of SSP level search is to bring Web users to the right Web destination. The objective of in-site level is to find exact information Web users are seeking.
