High-temperature high-k polyolefin by rational molecular design.
Proc Natl Acad Sci U S A
December 2024
Article Synopsis
- - Polymer film dielectrics are preferred for energy storage because they offer advantages like high breakdown strength, low dielectric loss, and easy processing, while the move towards high-density renewables increases the demand for high-temperature, high-k polymers.
- - A new design method enhances high-temperature polyolefins' dielectric constant by integrating phenyl pendants into their structure, allowing for better dielectric properties while still maintaining high thermal stability.
- - The resulting polymer, m-PNB-BP, achieves a notable dielectric constant of 4 at 150 °C and a discharged density of 8.6 J/m at 660 MV/m, presenting a promising approach for developing polymers ideal for capacitive energy storage under harsh conditions.
Jonas Salk (October 28, 1914 - June 23, 1995) was an American medical researcher celebrated for his pioneering work in virology, particularly the development of the first successful polio vaccine. This review highlights Salk's multifaceted talent and contributions. His research on the poliovirus led to the creation of the inactivated polio vaccine, proving that it could prevent the disease.

This study focuses on the removal of selenium from an aqueous solution using iron-doped dolochar. SEM, EDX, BET, XRD, FTIR, and P were conducted to determine the surface characteristics of iron-doped dolochar (FeD).
