  • In this paper, Fe3O4-ZnO heterostructure multifunctional nanoparticles (NPs) were successfully prepared in aqueous solution by ultrasound assisted thermolysis. First, iron oxide (Fe3O4) magnetic NPs were prepared by co-precipitation method. The Fe3O4 NPs were modified by 3-aminopropyltriethoxysilane (APTES) to have free amine (-NH2) groups on their surface, then, Zn2+ ions were added and stirred to adsorb onto the surface of Fe3O4-NH2 NPs in alkaline solution at a pH of 11.

  • As Bill Lubanovic and I were putting the final touches on this book, I overheard a conversation between two coworkers in our Cisco lab discussing Linux. The senior networking guru of the two made an interesting remark. He said that despite all his knowledge, he felt incomplete as a professional because he had never learned Linux. A moment later he and the other gentleman turned to me and looked me square in the eyes. I smiled and went on working. That evening, our director of Information Technology made an offhand remark to me during a conference that struck me as unusual.

  • The major producers were developing new products that utilized digital copying technology as opposed to light/lens technology. Some analysts expected that market growth in the nineties would be driven by "smart" multifunction devices that combined copying, faxing, scanning, and electronic printing functions. Competitors with direct sales forces would have an advantage because the complexity and pricing of these machines was too high for effective dealer distribution. Color copying represented another potential growth area.

  • Despite worldwide evidence of the low levels of female participation in social, educational, economic and political spheres, there is still a tendency to see it as a real problem only in a limited number of countries. Yet, as noted above, the reality is that no country in the world, no matter how advanced, has achieved true gender equality, as measured by comparable decision- making power, equal opportunity for education and advancement, and equal participation and status in all walks of human endeavour.
