Brazilian scientists reveal method of converting methane gas into liquid methanol - Chemie.de
Publicado em 08 de agosto de 2022
A group of researchers has succeeded in converting methane into methanol using light and dispersed transition metals such as copper in a process known as photo-oxidation. The reaction was the best obtained to date for conversion of methane gas into liquid fuel under ambient conditions of temperature and pressure (25 °C and 1 bar respectively).
The term bar as a unit of pressure derives from the Greek word for weight (baros). One bar is equivalent to 100,000 Pascals (100 kPa), which is [...]

Tube-dwelling anemone toxins have pharmacological potential, mapping study shows
Publicado em 30 outubro 2020Researchers based in Brazil and the United States have completed the first-ever mapping exercise to profile the toxins produced by tube-dwelling anemones, or cerianthids, a family of marine animals belonging to the same phylum (Cnidaria) as sea anemones, jellyfish and corals. The analysis revealed that the toxins that can act on the nervous system, cardiovascular system, and cell walls, among other functions, paving the way to the discovery of novel medications. "Tube anemones and sea [...]ver notícia -
