Synthesis of Nanoparticles Using Green Chemistry

Green Synthesis

By: Farid Badria,Mohamed AbouHabieb,Fatma Abdel Bar

Document from the year 2017 in the subject Chemistry - Bio-chemistry, Mansoura University, language: English, abstract: Forty-two medicinal plants were collected depending on their availability on Egypt. These plant were extracted and screened for their activity towards green synthesis of AgNPs. A new modified method was used in order to screen large number of extracts in short time (high throughput screening). In this method, the synthesized nanoparticles were evaluated in using 96-well plate which is transparent to facilitate the color monitoring and easy to be read spectrophotometrically using microplate reader. The green synthesis activity by the different plant extracts was monitored and evaluated by color change and UV-Vis absorption at time intervals. Out of these 42 plants, only 3 plants viz.,Pyllanthusemblicafruits, Psidium guajava leaves and Lawsoniainermisleaves, showed high AgNPs synthetic activity. The most active plant extracts were further partitioned with ethyl acetate. The results showed that the EtOAc fraction of the three active plants showed superior AgNPs green synthesis over their remaining aqueous. Thus, chromatographic columns were used to isolate the active compounds from the EtOAc fraction of each plant. Metal nanoparticles synthesis is a leading topic of research in modern material science owing to their distinctive potential applications in the field of electronic, optoelectronic, information storage and Health care. Among the all noble metal nanoparticles, silver nanoparticles are one the main products in the field of nanotechnology which has acquired limitless attention due to their unique properties such as chemical stability, good conductivity, catalytic and most important antibacterial, antiviral and antifungal activities. Nevertheless, there is still need for economic commercially viable as well as environmentally clean synthesis route to synthesize the silver nanoparticles.

Statistics, 3E

By: Robert A. Donnelly Jr. Ph.D.,Fatma Abdel-Raouf, Ph.D.

Statistics is a class that is required in many college majors, and it’s an increasingly popular Advanced Placement (AP) high school course. In addition to math and technical students, many business and liberal arts students are required to take it as a fundamental component of their majors. A knowledge of statistical interpretation is vital for many careers. Idiot’s Guides®: Statistics explains the fundamental tenets in language anyone can understand. Content includes: - Calculating descriptive statistics. - Measures of central tendency: mean, median, and mode. - Probability. - Variance analysis. - Inferential statistics. - Hypothesis testing. - Organizing data into statistical charts and tables.

Cytokines Modulators in Plants. Chemical and Therapeutics Studies

By: Farid Badria,Diaaeldin M. Elimam,Fatma M. Abdel Bar,Hosam M. Zaghloul

Master's Thesis from the year 2016 in the subject Medicine - Pharmacology, Pharmacy, , language: English, abstract: The aim of the present study is (1) the screening group of plants that are traditionally used as immune-enhancers in an attempt to find the major fractions that are responsible for the activity of these plants and correlating them with already published studies. (2) The Modification of structure of the most active immunomodulatory component through semisynthetic derivatization reactions. The modifications will be made in pursuance of gaining a deeper insight of the structural requirements for immunomodulatory activity. (3) Testing the immunomodulatory activities of both natural and semisynthetic compounds. And (4) studying the mechanism of action of the active compounds as antioxidantand anti-proliferative. Immunity is the body ability to identify and resist harmful pathogen. Metaphorically, the immunity is the body’s army that enables prevention as well as fighting of infectious diseasestoprotect self-tissues and organs from damage. The immune system has a multi-layered construction with multiple defense stages. The skin is considered the first barrier of immunity. Then, physiological barriers take place, which are body physical conditions for examplepH and temperature that affordunsuitableenvironments for pathogens to live. Then, if a pathogen has escaped the first barriers and entered the body, it deals with innate immunity as well as acquired and/or adaptive immunity. Both systems consist of number of molecules and cells that interact in a complex manner to detect and eliminate any threat. Detection as well as elimination relay on bonding of immune cellular surface receptors as well as chemical binding to pathogens to trigger complex interaction of signaling of immune response.

Palestinian Women

Narrative Histories and Gendered Memory

By: Fatma Kassem

Palestinian Women is the first book to examine and document the experiences and the historical narrative of ordinary Palestinian women who witnessed the events of 1948 and became involuntary citizens of the State of Israel. Told in their own words, the women's experiences serve as a window for examining the complex intersections of gender, nationalism and citizenship in a situation of ongoing violent political conflict. Known in Palestinian discourse as the 'Nakbeh', or the 'Catastrophe', these events of 60 years ago still have a powerful resonance in contemporary Palestinian-Jewish relations in the State of Israel and in the act of narrating these stories, the author argues that the realm of memory is a site of commemoration and resistance.
