Abstract: An ambient temperature curable hydrophilic PU oligomer includes a PU pre-polymer having a hydrophilic center group and a curable terminated group. The ambient temperature curable hydrophilic PU oligomer includes the moisture-curable hydrophilic PU oligomer such as isocyanate-terminated PU pre-polymer and free-radical curable hydrophlic PU oligomer. The isocyanate-terminated PU pre-polymer is synthesized by mixing at least one multi-isocyanate, at least one polyol and one or more diol monomer with hydrophilic group. The acrylate-terminated PU oligomer is synthesized by adding 2-hydroxyethyl methacrylate (HEMA) into the isocyanate-terminated hydrophilic PU pre-polymer. Either acrylate- or isocyanate-terminated PU oligomer can be applied on a textile or a glass surface with a thin-layer coating technology. The curing reactions of these hydrophilic thin-layer coatings are carried out with moisture or UV-radiation, respectively, at ambient temperature.

Abstract: Disclosed is a thermo-buckled micro actuation unit made of parylene, which is a polymer having high thermal expansion coefficient, for delivering liquid from a source liquid section to a target liquid section, including a substrate on which a thermo-buckled micro actuation unit is formed. The thermo-buckled micro actuation unit includes upper and lower films made of polymers of high thermal expansion coefficient, a metal resistor arranged between the two films, and a flow channel defined between the lower film and the substrate.

The self-polymerization takes place at ambient temperature and the resultants, cross-linked polymeric networked materials, are solvent insoluble and potential for adhesive, composite matrix and other applications. These insoluble materials are hydrolyzed in an acidic or basic condition to form the water soluble ?-amino acids.

Abstract: A manually operated brushless DC motor is disclosed herein, which is an educational electric motor and can overcome the shortcoming hard to visualize the movement of a motor due to the high-speed rotation of the motor. The manually operated brushless DC motor according to the present invention provides two switches to replace the brushes used in a conventional motor. Users/learners have to alternatively press the switches to complete a closed circuit and drive the motor to rotate. Only when the rotor rotates in synchronism with the pressing rate of the switches, the rotor accelerates. Otherwise the rotation speed of the rotor decreases. The manually operated brushless DC motor provides the users/learners with the opportunity of viewing the rotor rotating in a slow motion, and the experience of manually operating the motor.
