摘要:
The present invention provides a method for separating an amide from an amino acid ionic liquid. The method includes the step of providing a polar solvent and an extracting agent to the amino acid ionic liquid, so as to separate the amide from the amino acid ionic liquid. In the method of the present invention, there is no need to add ammonium for neutralization, such that no byproduct, ammonium sulfate, is formed. In addition, after the amide is separated from the amino acid ionic liquid, the amino acid ionic liquid can be recycled.

The present invention provides a catalyst composition for preparing an amide, including an amino acid ionic liquid having a cation of formula (I) and an anion selected from the group consisting of an inorganic acid group, an organic acid group and a combination thereof, wherein the numbers of the anion and the cation are such that the amino acid ionic liquid is electroneutral; and a Bronsted acid. The present invention also provides a method for preparing an amide in the presence of the catalyst composition, and the method has advantages such as decreasing viscosity of ionic liquid, and increasing conversion rate of ketoximes and selectivity of amides.

A concentrating photovoltaic (CPV) apparatus includes at least one lens unit, at least one solar cell chip unit, and a frame structure. The frame structure includes at least two opposite main walls, a plurality of upper and lower support bars extended between and connected to the two main walls, and two sidewalls. The main walls are each provided with at a predetermined position with at least one air opening and at two lateral ends with a first and a second connecting portion. Two ends of the upper and lower support bars are connected to the first and the second connecting portions, allowing the lens unit and the solar cell chip unit to be supported on and fixed to the upper and the lower support bars, respectively.
摘要:
A method of determining tag identifications is discloses. The method comprises: providing an index signal; receiving a responsive signal generated from tag matching the index signal; obtaining an identification code corresponding to the responsive signal; reader sending an acknowledgement and waiting for tag to respond a returned-acknowledgement. A searching process is repeated at the current node after a tag responsive signal is received to prevent signal suppression errors.

A baculovirus expression vector achieves dual functions of (1) subunit vaccine by displaying the influenza surface protein for humoral immune responses; and (2) DNA vaccine by expressing influenza surface protein for long-acting cellular immune response. A method for inducing immunogenicity in a host is also disclosed.
