INFLUENCE OF ELECTROMAGNETIC RADIATION ON THE PERMEABILITY OF ERYTHROCYTE MEMBRANES
The purpose of the survey is to experimentally study the influence of electromagnetic radiation from the decimeter range on the permeability of erythrocyte membranes. The object of the study was the blood of 80 white rats, 60 of them for three months were under the influence of electromagnetic radiation of the decimeter range. 20 animals of the control

A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami
A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.
