Biodegradable nanocomposites were prepared by adding ZnO nanoparticles to bacterial polyester poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) via solution casting technique. The morphology, thermal, mechanical, antibacterial, barrier, and migration properties of the analyzed. uniformly dispersed within PHBV without aid coupling agents, acted effectively as nucleating raising crystallization temperature level crystallinity matrix while decreasing its crystallite size. A gradual rise in...

The dispersed within the biopolymer without need for surfactants or coupling agents. morphology, thermal, mechanical, barrier, migration and antibacterial properties nanocomposites investigated. acted as nucleating agents, increasing crystallization temperature degree crystallinity matrix, mass transport barriers, hindering diffusion...
Castor oil (CO), which is a readily available, relatively inexpensive, and environmentally benign nonedible oil, has been successfully used as matrix material to prepare biocompatible biodegradable nanocomposite films filled with chitosan (CS)-modified ZnO nanoparticles. The biocomposites were synthesized via simple versatile solution mixing casting method. morphology, structure, thermal stability, water absorption, biodegradability, cytocompatibility, barrier, mechanical, viscoelastic,...
The performance of chemical sensors based on polymer nanocomposites with CNTs and graphene is revised, highlighting the role polymeric material.
Poly(propylene fumarate) (PPF)-based nanocomposites incorporating different amounts of polyethylene glycol-functionalized graphene oxide (PEG-GO) have been prepared via sonication and thermal curing, their surface morphology, structure, stability, hydrophilicity, water absorption, biodegradation, cytotoxicity, mechanical, viscoelastic antibacterial properties investigated. SEM TEM images corroborated that the noncovalent functionalization with PEG caused exfoliation GO into thinner flakes....
Carbon nanotubes (CNTs), the one-dimensional allotropes of carbon, have attracted noteworthy research interest since their discovery in 1991 owing to large aspect ratio, low mass density, and unique chemical, physical, electronic properties that provide exciting possibilities for nanoscale applications. Nonetheless, two major issues should be considered when working with this sort nanomaterial: strong agglomerating tendency, they are typically present as bundles or ropes nanotubes, metallic...
Breast cancer refers to a very common deadly class of malignant tumors, especially in women worldwide. In the present study, promising methodology has been developed simultaneously improve drug loading performance and achieve sustained release 5-fluorouracil (5-FU) as model for breast cancer. For this purpose, pH-sensitive biocompatible hydrogel chitosan/agarose/graphene oxide (CS/AG/GO) was first synthesized with glyoxal cross-linker. 5-FU-loaded nanocomposites (NCs) CS/AG/GO were then...
A pH-sensitive nanocomposite based on halloysite nanotubes (HNT) coated with polyacrylic acid (PAA)/carboxymethyl cellulose (CMC) hydrogel was synthesized for controlled delivery of curcumin (CUR) to MCF-7 cancer cells. Hazelnut oil added minimize the size and increase its uniformity via water/oil/water (W/O/W) double emulsion method. Likewise, Span 80 surfactant incorporated produce a nanoniosomal that increased stability retention CUR as an anticancer drug. The molecular interactions...
Machine learning (ML) models provide fast and accurate predictions of material properties at a low computational cost.
