Artemis III core stage receives a thermal protective coating
A team at NASA’s Mikudo Assembly Facility in New Orleans will move a liquid hydrogen tank for the agency’s SLS (space launch system) rocket to the factory’s final assembly area on April 22, 2025. The propellant tank is one of the five main components that make up the 212-foot tall rocket stage. Credit: NASA/STEVEN SEIPEL NASA has completed another step…

Infrared spectroscopy with machine learning detects early wood coating degradation
Improve the sustainability of wooden buildings. Credit: (Kyoto/Whitney Havel) From Japanese cypress to ponderosa pine, wood has been used in construction for thousands of years. Materials such as steel and concrete have taken over the construction of large-scale buildings, but timber has been revived and is increasingly being used in public and multiple buildings due to environmental benefits. Of course,…

The material acts as a biomimetic of teak wood and creates an environmental barrier coating.
The multiscale layered structure of teak wood provides excellent mechanical properties and environmental stability, which has inspired the biomimetic design of environmental barrier coatings. In this study, a multiscale nano Yb2Si2O7-Yb2SiO5 composite EBC with a layered structure similar to teak wood was realized by a new vapor/liquid phase alternating deposition method in plasma spray-physical vapor deposition (PS-PVD). In this process,…

Experiments show that coating rice seedlings with durian-derived nanoscale carbon dots helps rice grow in saline soils
Rice seedlings sprayed with a carbon dot mixture derived from durian skin (far right) are stronger than untreated seedlings (second from left) and have acquired genes that improve salt tolerance and photosynthesis without genetic modification. It has manifested. Credit: Adapted from ACS Nano 2024, DOI: 10.1021/acsnano.4c09001 Abnormal weather and pollution have increased salinity in some soils, making growing conditions harsher…
