In the conditions of outer space vacuum, metal parts can spontaneously bond together without heating due to the destruction of their protective oxide layer. This phenomenon poses serious challenges for spacecraft and requires special protective measures.
В вакууме космоса металлические детали могут самопроизвольно свариваться без нагрева, что представляет угрозу для космической техники. Для предотвращения этого инженеры используют специальные покрытия и смазки.
A new study has shown that the stingers and pincers of scorpions contain certain metals that strengthen their structure. The distribution of these elements is linked to the specific hunting and defense strategies of different species.
Researchers have developed new carbon materials with precisely controlled placement of nitrogen groups, enabling more efficient capture and easy release of CO₂ at low temperatures. This approach paves the way for creating more cost-effective and efficient technologies to reduce greenhouse gas emissions.
The asteroid Psyche, the largest metallic object in the belt between Mars and Jupiter, may be a fragment of a planetary core. A NASA mission launched in 2023 will help uncover its origin and structural features.
Scientists have developed an innovative method for extracting lithium from used batteries, which has proven to be significantly cheaper and more environmentally friendly than traditional techniques. This new approach could make lithium recycling a commercially viable and sustainable alternative to mining.
Chinese scientists have discovered that the fern Blechnum orientale can accumulate and crystallize rare earth elements, offering an environmentally friendly alternative to traditional mining. This breakthrough could reduce environmental harm and provide new ways to obtain valuable metals for modern technologies.
