We are heavily dependent on nature to meet our energy requirements and our ever increasing needs has raised many concerns!Use of self tinting Dynamic windows is an innovative approach to minimise our energy consumption without having to compromise on comfort.A group of chemists have now designed Dynamic Windows where the transparency of the window can be altered through reversible electroplating of Bi and Cu at the working electrode and Li+ insertion in a nickel oxide counter electrode.For more information - DOI: 10.1038/s41560-019-0332-3A conversation with Prof. Christopher Barile, Assistant ProfessorDepartment of ChemistryUniversity of Nevada, Reno
