Article Synopsis
- - The proliferation of electronic devices has increased their susceptibility to corrosion, especially in copper traces of printed circuit boards (PCBs), highlighting limitations in traditional protective methods like conformal coatings.
- - This study explores using cold atmospheric plasma (CAP) to apply ultrathin silicon oxide (SiO) coatings onto copper surfaces, focusing on how scanning speed affects film quality and corrosion resistance.
- - Results showed that a scanning speed of 45 mm/s yielded a 140 nm thick coating with 30-fold better corrosion resistance than uncoated copper, demonstrating the potential of CAP coatings over traditional methods in protecting electronic components like LEDs and PCBs used in agriculture.
Wearable electronics have become integral for monitoring physiological parameters in diverse applications, particularly in medical and military fields. e-Textiles, featuring integrated conductive threads or fabrics, offer seamless integration and comfort for prolonged contact with the body. Despite their potential, the biofouling of textile-based electrode systems by skin microbes remains a significant challenge, limiting their operational lifespan.

However, post-operative mesh infection remains a significant complication, elevating hernia recurrence risks from 3.6% to 10%, depending on the procedure type.

Despite their wide range of applications, many challenges remain primarily with respect to the complex synthesis and time-consuming manufacturing steps that are often required in the fabrication process of various devices with conductive polymers. Here, we demonstrate the novel use of cold atmospheric plasma (CAP)-assisted deposition technologies as a solvent-free and scalable approach for in situ polymerization and direct deposition of conductive polypyrrole-silver (PPy-Ag) nanocomposites onto the desired substrates under atmospheric conditions.

- The colon has a diverse microbial community crucial for metabolism, nutrition, and immune function, and changes in this microbiota can lead to metabolic diseases like obesity and colorectal cancer.
- Existing methods to study microbiota-diet interactions are often invasive or limited to fecal samples, making it difficult to get accurate spatial information.
- A new electronic-free smart capsule has been developed to allow targeted sampling of gut microbiota in the proximal colon, using a special pH-sensitive coating to ensure it only collects data from that specific region.
