This course is for graduates and professionals looking for greater knowledge and expertise in sustainable agricultural development. You’ll gain a strong understanding of the fundamentals of crop production, such as adaptation to climate and other environmental changes. You then explore how this expertise can help to design effective food production systems without placing unsustainable demands on the environment. The emphasis is on agriculture in tropical or developing countries, but the approaches can be used globally.
A high-performance version of the zinc-ion battery will enable stationary energy storage that promises to be cheaper, safer and more environmentally friendly than lithium-ion batteries. Until now, zinc-ion batteries have been severely hampered by their rapid degradation during use. Now, a KAUST team has developed a new electrolyte and electrode combination that improved several aspects of zinc-ion battery performance, particularly the stability over multiple charge and discharge cycles. To combat these issues, the team developed a water electrolyte with a very high salt concentration. The more salt ions present in the solution to bind surrounding water molecules, the fewer free water molecules are available to damage the electrodes.
