To tackle the shortcomings of conventional nano-YSZ thermal-barrier coatings—infrared semitransparency, low nanoparticle retention, and the formation of partially melted agglomerates during plasma spraying—researchers have encased each YSZ nanoparticle in a sacrificial carbon shell that protects it from melting throughout the deposition process. Once burned off, the film leaves nano-pores that, together with the preserved nanoparticles, greatly boost infrared scattering and lower simulated metal temperatures by 111.2 K—offering a scalable route to thermal-barrier coatings with superior radiation blocking and long-term high-temperature stability.
A new study in Forest Ecosystems reveals how fire history, vegetation type, and soil features jointly influence carbon storage in boreal forests. Researchers in Norway compared pine and spruce forests across regions with different fire legacies, and they found that pine forests store nearly twice as much organic carbon as spruce forests, with charcoal carbon stocks varying by region due to fire frequency, terrain microtopography, and organic layer depth. The study highlights the importance of localized forest management strategies for sustaining carbon storage in the face of climate change.
Excessive Malassezia yeast colonization in lesional skin has been found to cause psoriasis exacerbations. This paper published in Mycology found that oxymatrine inhibits Malassezia biofilm formation and ameliorates Malassezia-associated psoriasis by modulating oxidative stress, inflammation, and apoptosis.
