Cement production, responsible for 7.5% of global CO₂ emissions, faces decarbonization challenges. A novel strategy uses methane to co-produce syngas and clinker via a steel waste-derived iron-based catalyst, mimicking cement's inherent components. This approach slashes emissions by about 80% versus conventional methods and eliminates catalyst separation. Future integration with green power promises further reductions, positioning industrial waste as a potential player in sustainable cement manufacturing.
A metasurface-based approach is proposed for single-shot optical imaging that simultaneously captures all the three parameters of optical fields with arbitrary intensity, phase, and polarization distributions.
The study, the result of a collaboration between the Sant'Anna School of Advanced Studies in Pisa, Graz University of Technology, CSGI and the University of Florence, opens up new scenarios in the field of electronics. “Using simple and low-cost materials, we can develop innovative applications such as physical, chemical or environmental sensors on any surface,” says Francesco Greco, associate professor of bioengineering
Enhancing wheat plants’ sugar signalling ability could deliver increased yields of up to 12%, according to researchers from Rothamsted, Oxford University and the Rosalind Franklin Institute in a study published today in the journal Nature Biotechnology. That is an order of magnitude greater than annual yield increases currently being achieved through breeding.
