چکیده

A practical procedure for synthesizing cellulose nanospheres with sizes ranging from 60 to over 570 nm was developed. This methodology provides a near linear relationship between cellulose nanoparticle size and treatment time. The hydrolyzed nanocelluloses are predominantly cellulose II polymorphic crystalline structure and relatively uniform in particle size. 2007 Elsevier Ltd. All rights reserved.

Synthesis and Characterization of ‎Carboxymethyl Cellulose/Polystyrene ‎Core-Shell Nanoparticles by Miniemulsion ‎Polymerization

The first stage to have access to a reservoir is the drilling operation. The proper development of this operation plays a major role in increasing productivity. It must be pointed out that the drilling fluid (mud) is pivotal in achieving this objective. Among these fluids, water-based fluids are the most common ones, which have been utilized to drill approximately 80% of all wells and are m...
