To investigate the interaction between the total ionizing dose (TID) effect and displacement damage, this paper presents the experiment results of several CMOS integrated circuits’ radiation effect in a mixed neutron and gamma ray environment. The electrical and functional tests were made in four irradiation environments: 1. neutron (high neutron/gamma ratio); 2. gamma ray; 3. combined irradiation of neutron and gamma ray (low neutron/gamma ratio); 4. TID test after neutron irradiation. All the parameters were tested online. Compared with the single radiation environments, results show that the mixed neutron and gamma irradiation can induce a synergistic effect on the samples. In the neutron and gamma synergistic irradiation, the devices exhibit considerably severer degradation. The synergistic effect occurs while neutron and gamma exist synchronously. Where the percentage of gamma is comparable or larger than neutron at the levels of concern, one can expect synergistic effects will occur in the CMOS devices, and the TID effects should not be decoupled from nonionizing or displacement damage.

Aqueous suspensions of cellulose nanocrystals can be obtained by acid hydrolysis of lignocellulosic fibers. Cellulose nanocrystals correspond to defect-free rod-like nanoparticles that present remarkable properties such as light weight, low cost, availability of raw material, renewability, nanoscale dimension, and unique morphology. Because of these properties, cellulose nanocrystals have been largely applied as reinforcing fillers in nanocomposites materials. This paper discusses the preparation, morphological features, and physical properties of cellulose nanocrystals, as well as their incorporation in nanocomposite materials.

The development of carbon-based nanomaterials has extensively facilitated new discoveries in various fields. Carbon nanotube-based nanocomposites (CNT-based nanocomposites) have lately recognized as promising biomaterials for a wide range of biomedical applications due to their unique electronic, mechanical, and biological properties. Nanocomposite materials such as silver nanoparticles, polymers, biomolecules, enzymes, and peptides have been reported in many studies, possess a broad range of antibacterial activity when incorporated with carbon nanotubes (CNTs). It is crucial to understand the mechanism which governs the antimicrobial activity of these CNT-based nanocomposite materials, including the decoupling individual and synergistic effects on the cells. In this review, the interaction behavior between microorganisms and different types of CNT-based nanocomposites is summarized to understand the respective antimicrobial performance in different conditions. Besides, the current development stage of CNT-based nanocomposite materials, the technical challenges faced, and the exceptional prospect of implementing potential antimicrobial CNT-based nanocomposite materials are also discussed.
