In this paper, we use Polyethylene Oxide (PEO) particles to control the morphology of Formamidinium (FA)-rich perovskite films and achieve large grains with improved optoelectronic properties. Consequently, a planar perovskite solar cell (PSC) is fabricated with additions of 5 wt% of PEO, and ...
vention relates to LAS and bleach containing laundry bar compositions comprising a low moisture content of no more than about 3.5 % in the finished product composition and the addition of an effective amount of divalent metal sulfates, which delivers significant improvement in bar physical properties....

chlorine has the potential to affect physical and chemical properties of microplastics, potentially breaking existing bonds and introducing new ones. Introduction of chlorine-carbon bonds would be of particular concern, as substitution of hydrogen with chlorine atoms in organic compounds tends to increase...
