A photoelectrolytic cell (photoelectrochemical cell), on the other hand, refers either to a type of photovoltaic cell (like that developed by Edmond Becquerel and modern dye-sensitized solar cells), or to a device that splits water directly into hydrogen and oxygen using only solar illumination.esearchers at UCLA more recently developed an analogous polymer solar cell, following the same approach, that is 70% transparent and has a 4% power conversion efficiency. These lightweight, flexible cells can be produced in bulk at a low cost and could be used to create power generating windows.
What is a Bear Hug? A Bear Hug is a customized experience that brightens the life of a child going through cancer. Every Bear Hug is different because every child is different. We work with the child and their family to design a Bear Hug that meets their unique needs and interests.
The mention of a koala bear often conjures up an image of an adorable spoon-nosed creature cocking its head to one side while clinging to a tree. Now, scientists have figured out why the iconic Australian marsupials hug trees: The trunks help the koala bears keep cool, according to a new study. It can be a really useful way of getting rid of heat on a hot day, said study co-author Michael Kearney, an ecologist at the University of Melbourne in Australia. Tree huggers
