Abstract: Methods for cryopreservation of biological samples are provided. The biological samples are sub-millimeter or millimeter scale biological materials. The biological samples are embryos, such as Drosophila embryos. Methods for cryopreservation of Drosophila embryos using cryomesh are provided. The Drosophila embryos are collected, staged and treated to optimize the cryopreservation outcomes upon rewarming. Methods disclosed are efficient for maintaining stocks of Drosophila wild type and mutant strains. Methods are also disclosed for cryopreservation of other terrestrial organism embryos and/or aquatic organism embryos.

Abstract: The present invention relates to plastic welding process comprising using a dynamic heatsink that minimize the temperature rise of the predetermined surface whereby the surface quality of plastic welding is maintained.

Abstract: A method and composition for preparation of a high-elasticity polyurethane glove material and glove. The method for practicing the invention generally includes the steps of preparing an ultra-high molecular weight polyol, preparing a high-elasticity polyurethane glove material, and preparing a glove by dipping and forming. A high molecular weight polyether polyol is used in conjunction with polyurethane to increase resilience to a degree comparable with rubber material. Conventional polyurethane materials lack flexibility and do not allow for significant elongation or rebound. The material of the present disclosure may be used for medical applications and modifies polyurethane material to achieve properties similar to rubber materials. The polyurethane material resulting from the method according to the present disclosure has excellent biocompatibility and may be widely used in the medical field.

Abstract: In one aspect of the invention, the composite electro/optical microcable includes an outer sheath, and a composite electro/optical core covered by the outer sheath. The composite electro/optical core includes a strand of an insulated conductive wire set and an optical fiber unit, and a wrapping layer wrapping the strand of the insulated conductive wire set and the optical fiber unit. The insulated conductive wire set comprises one or more insulated conductive wires, each insulated conductive wire comprising one or more metal wires and an insulating layer covering the one or more metal wires. The optical fiber unit includes one or more optical fibers, one or more tight-buffered optical fiber cables, or one or more optical fiber ribbons.
