Summary: A cure kinetics investigation was conducted on a high temperature-resistant phenol novolac cyanate ester toughened with polyether sulfone blend, using non-isothermal differential scanning calorimetry. Thin ply carbon fiber prepreg based on this blend was fabricated, and plates for in-situ cure monitoring were manufactured using automated fiber placement. Online monitoring of curing behavior was carried out using Optimold sensors and Online Resin State software.

Summary: The study found that blending a small amount of HB-PED230 can effectively reduce the curing temperature of CE resin, while improving the bending strength and impact strength. Additionally, it was observed that as the amount of HB-PED230 increased, the flexural strength and flexural modulus of the copolymers were improved.

Summary: This study focuses on investigating the cure kinetics modeling of a vinyl ester pultrusion resin. By comparing 16 kinetic models, a model based on the n th-order autocatalytic reaction was found to have the best performance, with a proposed method to reduce errors resulting from simultaneous melting of additives. The research also demonstrates the significant influence of resin composition on the manufacturing process of composite materials.

Summary: In this study, a nonmetallic catalyst, 4-(4-aminophenoxy) phthalonitrile (PN-NH2), was used to reduce the curing temperature and time of cyanate ester (CE) resin. The addition of PN-NH2 significantly decreased the characteristic curing temperatures and activation energy of the CE resin. The cured resins with PN-NH2 showed superior mechanical and dielectric properties while maintaining reduced curing temperatures.

Summary: This study investigated the effects of two peroxide-based initiators and multi-walled carbon nanotubes on the cure behavior and kinetics of vinyl ester resin. The results showed that the molecular size of the initiators and the concentration of MWCNT significantly influenced the curing behavior of the resin, and MWCNT simplified the cure mechanism and reduced the activation energy.

Summary: This study aimed to investigate the effects of hypertension on silica nanoparticles (SiNPs) induced hemolysis and the underlying pathophysiological mechanism. SiNPs caused dose-dependent hemolysis, erythrocyte deformity, and increased susceptibility to lipid peroxidation. The concentration of intracellular Ca2+, annexin V, and calpain activity were also increased by SiNPs. Importantly, all these effects were potentiated in erythrocytes from hypertensive rats.

Summary: This study investigated the removal of bisphenol-A (BPA) from water using ozone microbubbles (OMBs). The results showed that the removal efficiency of BPA significantly increased from 41% to 98% when the initial pH of the medium was adjusted from 3 to 7. By employing OMBs, a high ozone utilization efficiency was achieved, resulting in the complete removal of BPA.

Summary: The curing kinetics and properties of three epoxy thermosets were investigated, with TMPK/DCPD showing the lowest reaction activation energy and highest T-g value, as well as superior dielectric and water resistance properties. This is attributed to the absence of secondary alcohol generated after curing and the hydrophobic tetramethyl-substituted biphenyl structure in TMPK/DCPD, making it a potential high-performance epoxy thermoset for applications in electronic packaging fields.

Summary: This paper describes a method to calculate the loss modulus of a viscoelastic polymer material at high frequencies based on vibrothermography. By measuring the surface temperature of the polymer coating and by solving the heat transfer equation, the heat intensity dissipated at the polymer is estimated. The measurement method is demonstrated with two different polymer materials at several frequencies and compared with results from dynamic mechanical analysis experiments.

Summary: Liquid crystalline elastomers exhibit unique shape memory behavior due to the combination of liquid crystalline orientation and rubber elasticity. Multiscale structural characterization upon deformation is crucial to understanding the structure-property relationships of these materials. Selective deuteration enables an improved neutron scattering contrast between different domains in the LCE, revealing the presence of highly aligned amorphous domains and the formation of structures in the micrometer scale.
