Carboxymethyl cellulose (CMC) is one of the most promising cellulose derivatives. Due to its characteristic surface properties, mechanical strength, tunable hydrophilicity, viscous properties, availability and abundance of raw materials, low-cost synthesis process, and likewise many contrasting aspects, it is now widely used in various advanced application fields, for example, food, paper, textile, and pharmaceutical industries, biomedical engineering, wastewater treatment, energy production, and storage energy production, and storage and so on. Many research articles have been reported on CMC, depending on their sources and application fields. Thus, a comprehensive and well-organized review is in great demand that can provide an up-to-date and in-depth review on CMC. Herein, this review aims to provide compact information of the synthesis to the advanced applications of this material in various fields. Finally, this article covers the insights of future CMC research that could guide researchers working in this prominent field.

Recent Developments of Carboxymethyl Cellulose.

Cellulose nanocrystals isolated from water hyacinth fiber (WHF) have been studied as a reinforcement for polyvinyl alcohol (PVA)-gelatin nanocomposite. Central composite design was used to study and optimize effects of the PVA, gelatin and cellulose nanocrystal (CNC) concentration on tensile strength and elongation of formed films. The results of this study showed that WHF CNC had a diameter range of 20–50 nm produced films reaching 13.8 MPa tensile strength. Thermal stability of the films was improved from 380 ℃ to 385 ℃ in addition of CNCs and maximum storage modulus of 3 GPa were observed when 5 wt% CNC was incorporated. However, water absorption, water vapour permeability (WVP) and moisture uptake of the films decreased in addition of CNC to the PVA-gelatin blends. Moisture uptake decreased from 22.50% to 19.05% while the least WVP when 10 wt% CNC added was 1.64 × 10–6 g/(m•h•Pa). These results show possibility for industrial application of WHF CNC and PVA-gelatin blends in biodegradable films for on-the-go food wrappers.

Mild Steel is one of the major construction materials used in the industries. It has a young modulus of 200GNm -2 . This paper focuses on the experimental study of the corrosion behavior and mechanism for mild steel in five different media namely: 0.1M of Hydrochloric acid, Underground (soil), Atmosphere, Salt water, Fresh water. Mild steel of diameter 1.2cm and 8.5cm long was used for this experiment and studied for a period of five weeks interval weighing and re-immersing. The weight losses were tabulated and analyzed graphically. It was observed that mild steel corroded in the different environments with decreasing intensity in the order of 0.1M of Hydrochloric acid, Underground (soil), Atmosphere, Salt water, Fresh water. It was then concluded that the laboratory immersion test remains the best method of screening of metal, it remains the quickest and most economical means for providing a preliminary selection of best suited materials for engineering applications as there is no simple way to extrapolate the results obtained from this simple test to the predictions of systems service lifetime.
