The continuous advancement and miniaturization of modern electronics have increased challenges related to electromagnetic interference (EMI) and thermal management. Polymer materials are commonly used for thermal regulation and EMI shielding because of their low weight, cost-effectiveness, and ease of processing. However, achieving both high electromagnetic shielding effectiveness (SE) and superior thermal conductivity (TC) in polymeric systems remains a major scientific challenge.

Hierarchically structured polyether-ether-ketone-based composites are prepared in this study by in situ deposition and dip coating using a simple and scalable method. Magnetic cobalt nanoparticles derived from magnetic metal-organic frameworks are deposited on carbon fiber felt featuring a macroscopic continuous conductive network.

This study aims to assess the cost-effectiveness of population-based CKD screening strategies in both the general population and adults with diabetes in China.
Methods: A validated microsimulation model of CKD was developed to evaluate the costs and health consequences of population-based CKD screening strategies from a societal perspective.

Methods And Materials: Four ninety-four patients were divided into relatively-high-radioactive (rHR), relatively-medium-radioactive (rMR), and relatively-low-radioactive (rLR) groups for retrospective treatment response comparison. The short-term outcomes were evaluated using the 1-month /3-month follow-up results based on RECIST 1.
Objectives: This study aims to identify prognostic factors associated with metastatic recurrence-free survival of cervical carcinoma (CC) patients treated with radical radiotherapy and assess the cure probability of radical radiotherapy from metastatic recurrence.
Methods: Data were from 446 cervical carcinoma patients with radical radiotherapy for an average follow up of 3.96 years.

With the rapid rise of new technologies such as 5G and artificial intelligence, electronic products are becoming smaller and higher power, and there is an increasing demand for electromagnetic interference shielding and thermal conductivity of electronic devices. In this work, hydroxyphenolphthalein type polyetherketone grafted carboxy carbon nanotube (PEK-C-OH-g-MWCNTs-COOH) composites were prepared by esterification reaction. The composites exhibited good thermal conductivity, and compared with (MWCNTs-COOH/PEEK) with randomly distributed fillers, (PEK-C-OH-g-MWCNTs-COOH) composites showed a significant advantage, with the same carbon nanotube content, the thermal conductivity of PEK-C-OH-g-MWCNTs-COOH/PEEK (30 wt%) was 0.
