A nano-sandwich construct was built by combining two-dimensional graphene nanosheets (GNSs) and one-dimensional carbon nanotubes (CNTs) to improve the mechanical properties of hydroxyapatite–polyetheretherketone (HAP–PEEK) scaffolds for bone tissue engineering. In this nano-sandwich construct, the long tubular CNTs penetrated the interlayers of graphene and prevented their aggregation, increasing the effective contact area between the construct and matrix. The combination of GNSs and CNTs in a weight ratio of 2:8 facilitated the dispersion of each other and provided a synergetic effect in enhancing the mechanical properties. The compressive strength and modulus of the scaffolds were increased by 63.58% and 56.54% at this time compared with those of HAP–PEEK scaffolds, respectively. The carbon-based fillers, pulling out and bridging, were also clearly observed in the matrix. Moreover, the dangling of CNTs and their entangling with GNSs further reinforced the mechanical properties. Furthermore, apatite layer formed on the scaffold surface after immersing in simulated body fluid, and the cells attached and spread well on the surface of the scaffolds and displayed good viability, proliferation, and differentiation. These evidence indicate that the HAP–PEEK scaffolds enhanced by GNSs and CNTs are a promising alternative for bone tissue engineering.

“…The pencil scratch hardness of 3a, 3b and 3c were 3H, 6H, and over 6H, respectively. The hardness of the film from cellul ose esters having oxirane groups (3) was improved, compared with those of cellulose esters having unsaturated groups (2). For quantitative evaluation of the film properties, a micro hardness tester was used ( Table 1).…”

This study deals with synthesis and curing of cellulose esters from renewable resources. Cellulose esters bearing unsaturated groups were prepared from cellulose and fatty acid in LiCl/N,N-dimethylacetamide solution. The subsequent epoxidation produced cellulose esters with oxirane groups in the side chain. The resulting cellulose esters were cured by thermal treatment to give transparent films with gloss surface. FT-IR spectrum revealed that reactive groups in the side chains reacted with each other during the reaction to produce cross linked network structure. The universal hardness and Young's modulus of the cross linked cellulose esters increased as a function of the number of reactive groups. The crosslinked cellulose esters also exhibited high glass transition and thermal decomposition temperatures. The development of the bio-based material from cellulose and plant oil-based fatty acid would be highly expected to contribute to global sustainability.

The uricase gold nanoparticles (AuNPs) composite nanomaterial was covalently immobilized on a biofilm, eggshell membrane. The uric acid biosensor was constructed by positioning the immobilized biofilm on the surface of a Clark dissolved oxygen electrode. The scanning electron micrograph revealed that the uricase AuNPs composite nanomaterial was successfully immobilized. The effects of enzyme loading, pH, concentration of phosphate buffer and temperature on the biosensor response have been stud ied in detail. The results showed that response time of the biosensor was 60 s, the linear range for the detec tion of uric acid varied from 1.0 µM to ~1.0 mM with a detection limit of 0.8 µM (S/N = 3) and relative standard deviation of 2.6% for 0.1 mM uric acid (n = 6). Some common potential interferents in samples demonstrated no interferences. The biosensor has been successfully applied to determine the uric acid level in urine and serum samples.
