Introduction
Nisreen Alhaj is currently an assistant professor at An- Najah National University. She did her PhD at Bordeaux university- France, and her project was related to the synthesis of Organosilanes for SAMs formation and biomolecules immobilization. While her master research was about the extraction of cellulose from olive industry solid waste.

Article
Functionalization of silica surfaces with silane-based self-assembled monolayers (SAMs) is widely used in material sciences to tune surface properties and introduce terminal functional groups enabling subsequent chemical surface reactions and immobilization of (bio)molecules. Here, we report on the synthesis of four organotrimethoxysilanes with var...
Article
Effective surface functionalization plays a critical role in the selectivity and sensitivity of sensing devices. While chalcogenide glasses (ChG) have received a lot of attention as promising optical materials for mid-IR biosensors, there have been just a few reported instances of their successful (bio)functionalization. In the present work, we exp...
Article
Click chemistry is widely used in materials and surface science for its high efficiency, ease of use and high yields. Azide-terminated SAMs have been prepared successfully by using three different deposition methods (post-functionalization and direct grafting by immersion as well as spin coating). Strikingly, our study shows that the reactivity of...

Olive industry solid waste (OISW) is a by-product generated in the process of olive oil extraction. It is a lignocellulosic material consisting of cellulose, hemicelluloses, lignin and other extractives. In this work, a process for hydrolyzing the OISW into its monomers glucose, the precursor of bioethanol was developed. The hydrolysis process invo...

Abstract In the present work cellulose powder was extracted from olive industry solid waste and then converted into cellulose acetate. The cellulose powder was extracted from olive industry solid waste by kraft pulping process and multistep bleaching p sequences. An elemental chlorine-free chemical bleaching sequence chlorine dioxide (D)-cold caust...
Thesis
Full-text available
In the present work a method for extracting cellulose from olive industry solid waste (OISW) has been developed. The method involves subjecting solid waste (about 0.5 Kg) to extraction with organic solvent ethylacetate, then to kraft pulping, followed by multistep bleaching processes. After bleaching an average cellulose yield of about 35% has...

In the present work, a method for extracting cellulose from olive industry solid waste has been developed. The method involves subjecting solid olive waste to kraft pulping, followed by multistep bleaching processes. The totally free chlorine chemical bleaching sequence APEP was the most effective and gave an average cellulose yield of about 35%. T...
