Approximately 42 per cent of the European Union (EU) land area is devoted to agriculture, supporting the EU in being the world’s largest exporter of agri-food products4,8. Policies are being developed to promote sustainable crop production, which requires up-to-date and accurate maps to prov...
Apart from that, Kiev and the international community must recognize the new “territorial reality” on the ground, Galuzin stressed, apparently referring to the incorporation of the four former Ukrainian regions of Kherson and Zaporozhye, as well as of the Donetsk and Lugansk People’s Republics...
Bifunctional nanomaterials that possess desirable properties in a single entity have been the focus of cutting edge science in recent years1–5. For instance, nanomaterials with bifunctional properties such as luminescence, mag- netism and high contrast bioimaging with magnetic resonance imaging (MRI) ...

So whether we get a half dozen seven-oh's this year with huge loss of life or a series of 8's and larger is really outside the scope of this project. Not much anyone can do about it, except have food, water, seeds and a mindset that will allow you to start over and prosper un...

This is mainly because defects are easily created in these hosts due to the charge compensation and cation disorder mechanisms [24]; in addition, they exhibit wide band gaps, allowing deep traps to be created and further increasing the persistent lifetime [26,27]. As for the dopants, ...
