Reduction of Energy Consumption in Cement Industry Using Zinc Oxide Nanoparticles

Autor: Dalia Ahmed Mohammed Osman, Mustafa A. Mustafa, Omer Nur

The present study investigates the possibility of introducing zinc oxide nanoparticles into the cement raw mix so as to reduce the energy consumption and CO2 emissions during processing. Zinc oxide nanoparticles are prepared via a hydrothermal growth

Synthesis and biological evaluation of novel pyrimidines derived from 6-aryl-5-cyano-2-thiouracil

Autor: Asma Mohamed Mahran, Sherif Shaban Ragab, Dalia Ahmed A. Osman, Nasser A. Hassan, Allam Abdelhamid Hassan

Publikováno v: Zeitschrift fur Naturforschung. C, Journal of biosciences. 71(5-6)

Starting from 6-aryl-5-cyano-2-thiouracil derivative 1a–f, a series of novel thiazolo[3,2-a]pyrimidines 4a–f were synthesized. The mechanism and the regioselectivity of the studied reactions are discussed. In addition, a series of tetrahydro-4-H-
