A trio of researchers at the University of British Columbia has found that froghoppers have cibarial pumps capable of sucking the xylem from plants by producing negative pressure exceeding 1 megapascal. In their paper published ...
In solar cells, about two third of the energy of sunlight is lost. Half of this loss is due to a process called 'hot carrier cooling' where high energy photons lose their excess energy in the form of heat before being converted ...
