High-temperature laser sintering (HT-LS) is a very promising additive manufacturing process for the production of parts complex geometry highly demanding applications. Poly(aryl ether ketone) polymers such as poly(ether ketone), and ketone (PEKK) have attracted increasing interest during last decade use in HT-LS. Among them, PEKK offers advantage exhibiting tunable melting temperature crystalli...

Microwave assisted reactions have gained considerable attention, due to versatility and reduction ofsolvent and reaction time. The reaction of a nano-coconut shell and boron tri-fluoride in diethylether solvent resulted in preparation of nano-coconut shell-BF3 as a catalyst. The nano-coconutshell-BF3 catalyst has been characterized by fourier transform infrared spectroscopy (F...

Single-crystal X-ray analysis of the 5'-bromo-l',3'-xyly~-l8-crown-5* tert-butylammonium hexafluorophosphate complex shows that the complex is of the "nesting" type in which the cation and the aryl group are on the same face of the macroring and that the macroring has a (ag'a)(ag-a)lag'a)(ag-a)(ag'a)lag-a) eonformation. Among crown ethers with aryl-sub-units, 1' ,3'-xylyl crown ethers (1) have ...
