To further improve heterogeneous catalysts, it is required to analyze the complex processes on their surfaces, where the active sites are located. Scientists of Karlsruhe Institute of Technology (KIT), together with colleagues from Spain and Argentina, have now reached decisive progress: As reported in Physical Review Letters, they use calculation methods with so-called hybrid functionals for the reliable interpretation of experimental data. (DOI: 10.1103/PhysRevLett.125.256101). Many important technologies, such as processes for energy conversion, emission reduction, or the production of chemicals, work with suitable catalysts only. For this reason, highly efficient materials for heterogeneous catalysis are gaining importance. In heterogeneous

No-meat Diet Everywhere Will Not Solve Climate Change

No-meat Diet Everywhere Will Not Solve Climate Change by Iswarya on  December 17, 2020 at 12:38 PM People in developed countries like the US or Europe are urged to consume less meat as part of adopting a healthier and low emissions diet. But that is not a universal solution as livestock are critical to diets and incomes in low or middle-income countries, according to a new study. The findings of the study are published in the journal Environmental Research Letters. Conclusions drawn in widely publicized reports argue that the main solution to the climate and human health crisis globally is to eat no or little meat but they are biased towards industrialized, Western systems, said Birthe Paul, the lead author and environmental scientist at the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT).
