Autor: Ghada A. Attia, Adel S. Bediwy, Radwa M. Ashour

Publikováno v: The Egyptian Journal of Bronchology, Vol 11, Iss 3, Pp 224-230 (2017)

Abstract Background Hypoxemia is the most serious threat to organ function. Therefore, the goal is to reverse tissue hypoxia. The aim of this study was to compare heated and humidified high-flow nasal cannula (HFNC) with conventional low-flow nasal c

Green Synthesis of Metal-Organic Framework Bacterial Cellulose Nanocomposites for Separation Applications

Autor: Radwa M, Ashour, Ahmed F, Abdel-Magied, Qiong, Wu, Richard T, Olsson, Kerstin, Forsberg

Publikováno v: Polymers

Metal organic frameworks (MOFs) are porous crystalline materials that can be designed to act as selective adsorbents. Due to their high porosity they can possess very high adsorption capacities. However, overcoming the brittleness of these crystallin

Importance of the surface chemistry of nanoparticles on peroxidase-like activity

Autor: Wenyi Zheng, Radwa M. Ashour, Ramy El-Sayed, Heba Asem, Fei Ye, Mamoun Muhammed, Moustapha Hassan

Publikováno v: Biochemical and Biophysical Research Communications. 491:15-18

We report the studies on origin of peroxidase-like activity for gold nanoparticles, as well as the impact from morphology and surface charge of nanoparticles. For this purpose, we have synthesized hollow gold nanospheres (HAuNS) and gold nanorods (Au
