Publication number: 20220197122Abstract: Disclosed is a non-coaxial projection light source system including a light source, a fluorescent wheel, and a converging shaping lens group located between the light source and the fluorescent wheel. Excitation light emitted by the light source is emitted to the converging shaping lens group in an optical axis direction inclined to the converging shaping lens group and then is emitted to the fluorescent wheel. Radiating fluorescent light generated by excitation on the fluorescent wheel is emitted to the converging shaping lens group and then is converged to a light path direction different from the excitation light to be output.Type: ApplicationFiled: March 10, 2020Publication date: June 23, 2022Inventors: Bo ZHONG, Shi XIAO, Lei YIN

Patent number: 7880053Abstract: Methods of using genetically-transformed plants in the phytoremediation of lead are described. Unlike many organisms in which only 10-kDa ACBPs have been identified, there exists a family of six ACBPs in the model plant Arabidopsis. Other than a function in mediating the transfer of acyl-CoA esters in plant lipid metabolism, all six Arabidopsis ACBPs can bind the heavy metal lead and are therefore applicable for phytoremediation. These methods of phytoremediation will provide a cheap, simple and efficient method in the removal of contaminating lead from soil/water/environment by the growth of the ACBP-overexpressing genetically-transformed plants in the contaminated environment. There is also provided a method to remove lead from contaminated water.Type: GrantFiled: April 3, 2008Date of Patent: February 1, 2011Assignee: The University of Hong KongInventors: Mee Len Chye, Shi Xiao, Wei Gao
