  • Publication number: 20180023212
    Abstract: Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on the as-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.

  • Publication number: 20180002245
    Abstract: In embodiments, the present invention relates to liquid formulations containing hydrophobic, biodegradable polymers dispersed within a Non-aqueous Organic Solvent Delivery System (NOSDS) that is designed to coat fertilizer granules with a hydrophobic film utilizing simple application equipment such as mixers, blenders and tumblers. This film can impede the dissolution of fertilizer components by water improving fertilizer efficiency. The NOSDS can be aprotic solvents, protic solvents and mixtures of protic and aprotic solvents which are environmentally friendly, have flashpoints above 145° F., and are inherently rated safe for contact with humans and animals. The hydrophobic polymers are the reaction product of aldehyde(s) and nitrogen containing compounds.

  • Publication number: 20170373266
    Abstract: A light-emitting diode, a method for fabricating the same, and a display device are disclosed. The light-emitting diode includes a first and second electrode; a first carrier transporting layer, a light emitting layer, and a second carrier transporting layer which are arranged between the first and second electrode in this order The light-emitting diode further includes a second carrier transporting layer which is arranged between the light emitting layer and the second electrode. The second carrier blocking layer blocks a portion of the second carrier from being transported to the light emitting layer. This decreases the injecting efficiency of the second carrier, improves an injecting balance between the second carrier and the first carrier with a low injecting efficiency, avoids energy consumption in the form of heat, and increases the light output efficiency and lifetime of the light-emitting diode.

  • Patent number: 9826979
    Abstract: An introducer for being fitted with a circular stapler, is a flexible plastic member in a whole shape of conical with an inner cavity; the introducer has a proximal end and a distal end, outer diameter of the introducer is gradually increased from the distal end to the proximal end and a maximum outer diameter of the proximal end is less than or equal to a maximum outer diameter of a staple cartridge assembly; when pulled by an external force, the plastic member may be unwound spirally and finally forms a strip body capable of being disengaged from the circular stapler. The introducer provided by the present disclosure has the advantages that: as the maximum outer diameter of the introducer is approximately equal to the maximum outer diameter of the staple cartridge assembly, the process of introducing can be achieved without bad influence resulting from increasing the outer diameter of the circular stapler.
