Fabrication of Low-Molecular-Weight Hyaluronic Acid–Carboxymethyl Cellulose Hybrid to Promote Bone Growth in Guided Bone Regeneration Surgery: An Animal Study

Bone regeneration surgery is a common dental procedure used to regenerate enough bone to properly heal dental implants. When this process is used on maxilla sinuses, hyaluronic acid can be used as an auxiliary material to raise the graft material handling characteristics. Using dental pulp stem cell cells, the proliferation of a manufactured L-HLA was investigated. New bone formation in rabbit calvaria defects treated with L-HLA/CMC at four weeks was almost two times higher than in defects filled with HLA/CMC at 8 weeks, according to HE-stained images. With these findings, it is safe to say that L-HLA helps with bone healing more than H-HLA, and that the L-HLA/CMC developed in this report is a potential candidate for increasing bone healing success in the case of guided bone regeneration surgery.

Preparation and some Physical Characterization of Rice Starch - Carboxymethyl Cellulose as Hemostatic Film

Rice starch and carboxymethyl cellulose are natural polymers that can be widely used for several biomedical applications, such as hydrogels, capsules, drug delivery system, wound dressing. This paper was designed to prepare and investigate the correct weight ratio of RS/CMC blend films by solution casting technique. The final results revealed that the optimal ratio of RS/CMC blend film to be used was 60/40. In addition, the cross-sectional SEM photographs of mixed films demonstrated the miscibility of RS and CMC. According to this report, the RS/CMC mixed film can be used as a hemostatic film.

Synthesis of Carboxymethyl Cellulose/Bentonite/N-P-K Composite as Slow-Release Fertilizer Model Using Twin-Screw Extruder

At 1:0. 5, the weight ratio of CMC to N-P-K was adjusted. The composites' mechanical properties were determined by tensile and compressive strength, water absorption capacity, and a stability test in water. The increased natural bentonite content in the composite reduced the tensile and compressive strength, but increased water absorption capacity and stability, according to the author. From CMC/Bentonite/N-P-K's kinetic release model of pseudo-second-order, the N-P-K was released.

Influence of hydroxyethyl and carboxymethyl celluloses on the rheology, water retention and surface tension of water-suspended microfibrillated cellulose

Abstract Water-soluble polymers have been shown to increase the flow stability and water retention capability of highly branched and polydisperse MFC, as well as changing and monitoring their rheological behavior. The pure MFC suspension demonstrated high visibility at lower shear stress and shear-thinning behavior at higher rates, with two yield zones showing a secondary deflocculation of smaller and more rigid fibril structures and their alignment/alignment in the direction of flow. Increasing the MFC suspension gel-strength, improving its flow and viscoelastic performance, as well as recovery after deformation, according to the carboxylic groups at CMC, who also decreased the interactions between the fibrils and subsequent smaller aggregates with their integrations.

Facile Synthesis and Characterization of CeO2-Nanoparticle-Loaded Carboxymethyl Cellulose as Efficient Protective Films for Mild Steel: A Comparative Study of Experiential and Computational Findings

EOCP-time, EIS, and PDP tools investigated the corrosion resistance of uncoated and coated mild steel in 1. 0 million HCl solutions. In addition, DFT analysis and MC simulation demonstrated the connection between coating films' structure and their corrosion resistance. The prepared CeO2-CMC-coated films demonstrated excellent corrosion resistance, according to the researchers' findings. DFT calculation and MC simulation established the effect of coated film manufacturing on its durability capacity, which was in accordance with the experimental findings.

Characteristic and mechanism analysis of sludge polymer by adding carboxymethyl cellulose-g-acrylic acid for sludge utilization

Experimental results show that when CMC:AA= 1:12 and CMC-g-AA gel content is 50%, sludge polymer has improved water absorption and retention results, and the water retention time is extended for u223 days. In addition, an analysis of variance and multiple comparisons shows that sludge polymer's particle size and water absorption times have significant effects on the water absorption and retention properties of sludge polymer.

Enhanced functional properties of biodegradable Polyvinyl alcohol /carboxymethyl cellulose (PVA/CMC) composite films reinforced with L-alanine surface modified CuO nanorods

Abstract We're back in this paper we've introduced a novel biogenic preparation of the CuO nanorods and its surface modification with L-alanine amino acid initiated by microwave irradiation. Different characterization methods were used to investigate the effects of surface functionalized CuO nanorods on the polyvinyl alcohol/carboxymethyl cellulose film physico-mechanical properties. PVC/CMC matrices filled with 8 wt% CuO-L-alanine, increased from 28. 58 MPa to 43. 40 u00b1 0. 83 MPa, UV shielding capability, and barrier to the water vapors were all greatly enhanced, with a significant increase in tensile stability, from 28. 58 u00b1 0. 73 MPa, UV shielding ability, and barrier to the water vapors. In these circumstances, the newly manufactured nanocomposite films can be used as an effective food packaging material.

Controlled Dispersion and Setting of Cellulose Nanofibril (CNF) - Carboxymethyl Cellulose (CMC) Pastes

This work investigated the redispersion and setting of highly loaded cellulose nanofibril pastes with carboxymethyl cellulose. With a CMC degree of substitution of 0. 9, the adsorption of CMC onto the CNF fibrils was determined by zeta potential and titration, resulting in a surface charge decrease of 61 percent from 36. 8 mmol/g COOH to -58. 1 mmol/g COOH for CNF+CMC with a surface charge increase of 61 percent. Dried CNF with adsorbed CMC was discovered to be completely redispersible in water and re-extruded back into a cord without any difficulties, and without any difficulties. Both water and a solid alkaline solution was used to measure the degree of redispersion or setting obtained by the untreated and chemically treated CNF+CMC. Both turbidity and FTIR results were consistent with water uptake of the differently treated and dried CNF+CMC materials.
