Abstract: Methods of preparing a composition comprising non-ionic, radioactive gold nanoparticles (R-GNPs) are disclosed. The method comprises: a) providing an aqueous composition comprising gold (Au-197) ions in the absence of a template; and b) exposing the aqueous composition in the absence of the template to neutron irradiation to generate the composition comprising the non-ionic R-GNPs. Alternatively, the method comprises: a) providing an aqueous composition comprising gold (Au-197) nanoparticles (GNPs) in the absence of a template; and b) exposing the aqueous composition comprising the GNPs in the absence of the template to neutron irradiation and thereby generating the composition comprising the non-ionic R-GNPs. Compositions that comprises mesoporous silica nanoparticles (MSNs) and non-ionic R-GNPs encapsulated within pores and/or channels and further anchored to the surfaces of the MSNs, and methods of making the same are also disclosed.

Abstract: A windshield wiper blade assembly having a primary yoke on which is mounted a spoiler which is formed with a curved front side and a generally triangular rear side, the spoiler having one end provided with a first bracket and another end provided with a second bracket, a bottom of the first bracket having two clamping members formed with two opposite semi-cylindrical recesses configured to fit into a first elongated opening of the primary yoke, the second bracket having two curved arms at two ends thereof configured to fit into a second elongated opening of the primary yoke, whereby the spoiler will give a downward pressure to the windshield wiper to prevent the windshield wiper from lifting from the windshield when the driving speed is high.
