Biodegradable RF Metamaterial Perfect Absorber for Wireless Soil pH Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
This study proposes a wireless soil pH sensor using a sheet‐type perfect absorber metamaterial. This sensor has a uniform water‐soluble Mg film at the bottom coated with hydroxyapatite that degrades depending on the pH, and a periodic square split ring resonator metamaterial structure made on top of a lossy dielectric plate.

Aerosol Jet Printing of Superhydrophobic Surfaces

open access: yesAdvanced Materials Technologies, EarlyView.
A novel method for creating spatially programmable superhydrophobic surfaces using an aerosol jet printer is presented. This technique allows precise deposition of micrometer‐sized polymer solution droplets onto a substrate, with control over surface morphology, microstructure, and wettability through solvent evaporation modulation.

Extraction of Human DNA from Soil: Protocol Adaptations [PDF]

open access: yesarXiv
PCR-based analysis of DNA is utilized in a wide variety of fields, including Forensic Science. Aside from the more common ample sources, material analyzed here can refer to specimen excavated from a soil environment, or a sampling of the soil itself to recover DNA leached into the soil from decomposing human remains or from body fluids intermingled ...
