Poly (ether-ether-ketone) (PEEK) is one of the most promising engineering plastics in aerospace engineering because of their reliable mechanical properties under various conditions. However, next-generation engineering plastics also call for more comprehensive outputs, such as higher thermal conductivity and antiwear performances. Boron Nitride Nanotubes (BNNT) have been proven to have outstanding physical properties as additives to the resin of the composites. In this article, the influence of BNNT additives on the PEEK resin is studied to provide a more insightful understanding of the development of BNNT-reinforced engineering plastics in the future. It has been found that the interfacial shear strength (IFSS) between BNNT and PEEK is 151% higher than carbon nanotube reinforcements., and amino groups (–NH2) modified BNNT can further improve the IFSS value by 14%. This mechanical improvement is further evaluated, and the molecular mechanisms are explained with an atomistic resolution.

Clay platelets/cellulose nanofibril nanocomposites are recyclable engineering materials of interest for sustainable development. There is substantial experimental data for mechanical properties, but modeling efforts are scarce. Here, a conceptual unit cell with voids was used in finite element modeling. Predictions for the in-plane modulus taking voids into account were more accurate than the classical rule of mixtures. Simulations also reveal that the cellulosic matrix undergoes shear and tensile deformation with inclined fracture located near the end of platelets for low clay content while predicting brittle tensile failure for high clay content. The results from the unit cell approach provide improved understanding of experimental observations, supporting the strive to better understand mechanisms of deformation and fracture.

The blood-brain barrier (BBB) is a multicellular neurovascular unit that serves as a highly impermeable cellular barrier to regulate brain homeostasis, protect the central nervous system, and respond to different physiological and pathological states. Recently, new drugs have been discovered to treat neuropathology. However, because BBB blocks the delivery of drugs to the central nervous system (CNS), it is still difficult to translate the treatment of CNS diseases into clinical results. Therefore, overcoming the BBB and realizing efficient delivery of therapeutic drugs is of great significance for the diagnosis and treatment of various neurological diseases such as Alzheimer’s disease, Parkinson’s disease and glioblastoma. Nano drug delivery system (NDDS) has the characteristics of high biocompatibility, high drug load, improving pharmacokinetic behavior of drugs in vivo, achieving targeted drug delivery, controlled drug release, etc. Therefore, in the field of trans-BBB drug delivery, It has broad application prospect for the diagnosis and treatment of various neurological diseases. This paper reviews the latest research on NDDS crossing BBB at home and abroad, providing new ideas for the diagnosis and treatment of CNS diseases.

Polymeric composites with the hybrid filler network for high-performance electromagnetic interference (EMI) shielding brought increasing interest. Herein, UHMWPE/ground tire rubber (GTR)/conductive carbon black (CCB) (UGC) composites with a hybrid segregated structural CCB-GTR were constructed by solid-phase shear milling (S3M), mechanical blending, and compacted molding processes. The percolation behavior of electrical conductivity and EMI shielding effectiveness (SE) of composites was described using Sigmoidal/Growth models, and its EMI shielding mechanism was discussed. Results showed that the EMI SE of U30G70C20, U50G50C20, and U70G30C20 composites were found to be 37.5, 41.7, and 43.8 dB, respectively, due to constructing a hybrid network. The attenuation rate of microwave radiation is above 99.99%, and the shielding mechanism is mainly electrical loss. Moreover, the relationship between electrical conductivity and EMI SE is consistent with Sigmoidal/Growth models, indicating that Sigmoidal/Growth models can successfully predict the percolation threshold of the EMI SE of UGC composites.

Ti3C2Tx (MXene) is prone to surface oxidation because of the presence of oxygen surface terminals in its surfaces. In this work, the effect of oxygen surface terminals has been reduced by replacing it with other surface terminals or thin layers of heteroatom at the interlayers. These resulted in increasing the interlayer spacing from 9.3 Å up to 12.5 Å with better flexibility properties, thereby facilitating electron/mass transports by exposing enough active surface areas. The carbon nanoplated MXene showed enhanced specific capacitance of 110 F/g at 2 mV/s in LiOH electrolytes for superior supercapacitor applications.
