The invention relates to a fluorescent lamp for the illumination of plants, having a tubular discharge vessel, two electrodes which are fused in a gastight manner into the ends of the discharge vessel, a fill comprising at least a noble gas and mercury, and a phosphor coating on the inner wall of the vessel, the phosphor coating at least including a europium-doped barium magnesium aluminate phosphor of the BaMgAl10O17:Eu type and a cerium- and terbium-doped gadolinium zinc magnesium pentaborate phosphor of the Gd(Zn,Mg)B5O10:Ce,Mn type, and, to generate light with as high a light yield as possible and with a color temperature of between 4000 and 5500 K, the phosphor coating additionally includes an antimony- and manganese-doped calcium halophosphate phosphor of the Ca10(PO4)6(F,Cl)2:Sb,Mn type. This novel phosphor coating allows the light yield to be increased by 10% if the proportion by weight of the individual phosphors is optimized.

Lipid compositions comprising specific mixtures of edible synthetic triglycerides are provided that are useful in formulating food products having highly desirable dietary benefits. The novel lipid compositions allow simultaneous access to highly desirable dietary benefits such as delivery of calorie reduction, weight management, health benefits, or any combination thereof, and they also may be formulated trans-fatty acid free.

A silver alloy etching solution comprises 1-60 weight portions of hydrogen peroxide, 1-60 wt. portions of sulfuric acid, nitric acid or organic acid, and 5-90 wt. portions of water. The other silver alloy etching liquid comprises 1-60 weight portions of ammonium, 1-60 weight portions of hydrogen peroxide, and 0-96 portions of water.

The invention discloses a solar cell gel electrolyte and a preparation method and application thereof. In the invention, the gel electrolyte is prepared by adding novel dendritic ionic liquid into liquid electrolyte of non-polymeric ionic liquid, additive and iodine monomer, hermetically stirring the mixture for 1 to 20 hours at the temperature of between 50 and 140 DEG C and uniformly dissolvingthe novel dendritic ionic liquid. The gel electrolyte is dropwise added or injected into the space between a photoanode dye titanium dioxide membrane and a Pt electrode while the gel electrolyte is hot; the gel electrolyte is further heated and subjected to evacuation, so that the gel electrolyte is completely impregnated into the titanium dioxide membrane serving as a porous membrane; and the components are packaged to prepare a quasi-solid fully ionic liquid gel solar cell. The gel electrolyte prepared in the invention does not comprise conventional toxic solvents and thus has the advantages of ready availability, easy package and high stability and high efficiency of the cell. The cell has a few assembly processes and low cost. When a xenon lamp is utilized to simulate the sunshine at the room temperature environment, the measured maximum photoelectric conversion efficiency of the cell is 6.0 percent under the condition that the light intensity is 100mW / cm<2>.
