  • Patent number: 10153438
    Abstract: An organic light-emitting device containing a compound having a lone electron pair and a ? electron orbital, the compound emitting fluorescent light by such a mechanism that when at least a part of electrons constituting the lone electron pair is excited to an excited triplet state 3n?* through n?* transition, the part of electrons undergoes inverse intersystem crossing from the excited triplet state 3n?* to an excited singlet state 1n?*, and returns from the excited singlet state 1n?* to the ground state, at which the fluorescent light is emitted. The organic light-emitting device has a high light emission efficiency.

  • Patent number: 8709578
    Abstract: A bamboo scrimber includes a plurality of pressure-pressed bamboo strips impregnated with an adhesive and modified through heat-treatment. Each of the bamboo strips is formed with a plurality of slots penetrating through the bamboo strip substantially in a direction of thickness defined by the bamboo strip. A substantially longitudinal direction defined by the slots is substantially consistent with a substantially longitudinal direction defined by fibers of the bamboo strip.

  • Patent number: 7981233
    Abstract: A method of forming a board suitable for use as container flooring uses bamboo and fast-growth low-density wood. The method includes the step of overlaying thin layers of high-density bamboo composites on surfaces of a core layer which can be the composite of wood veneer and wood strand-based composite, or wood veneer and bamboo stripe sheet composite. The benefits of bamboo and wood materials are combined to produce a bamboo-wood composite board having sufficient mechanical and physical strength and durability for use as container flooring.
