Title: A urea multi-walled carbon nanotubes fertilizer (uf-mwnts)
Inventor: AZIZAH SHAABAN
Filed: 2015-12-31
Abstract: Abstract A urea multi-walled carbon nanotubes fertilizer (UF-MWNTs) (100) comprising multi-walled carbon nanotubes (MWNTs) (102) and a urea fertilizer (UF) (104). The multi-walled carbon nanotubes (MWNTs) (102) are refluxed with nitric acid to obtain functionalized multi-walled carbon nanotubes (fMWNTs). Further, the functionalized multi-walled carbon nanotubes (fMWNTs) are reacted with the urea fertilizer (UF) (104) resulting in covalent interactions between the functionalized multi-walled carbon nanotubes (fMWNTs) and the urea fertilizer (UF) (104) to obtain the urea multi-walled carbon nanotubes fertilizer (UF-MWNTs) (100).

Abstract: In the case of a profile 1, in particular an extruded profile, for producing glazing arrangements, glass structures or the like, the profile 1 has three essentially parallel channels 2, 3 which, on their outer surface, have mutually parallel through-passages, in particular slots 5, 6 which are bounded by inwardly projecting borders 27, 28, the through-passages or the slot 5 of the central channel 2 being located at a greater distance from the base surface 4 of the profile 1 than the through-passages or slots 6 of the lateral channels 3. The clamping devices for glass panes 8 are formed by sealing profiles 7, 9, 10 which can be latched in a releasable manner to the through-passages or slots 5, 6 in the longitudinal direction of the profiles 1, it being the case that the width of the sealing profile 7, which can be connected to the through-passages or slots 5 of the central channel 3, is greater than the width of the central channel 2, in order thus, by over-engagement, to retain glass panes 8 or covering or edge elements in a sealing manner. <IMAGE>
