Students investigate the polarity of the water molecule and design tests to compare water to less polar liquids for evaporation rate, surface tension, and ability to dissolve certain substances.

Now, Chan and colleagues describe a previously unrecognized late phase of cell polarity in some CD4 + T cells that is controlled by CRTAM (MHC-class-I-restricted T-cell-associated molecule ...

It was confirmed, for the first time, that a hydrogen bond is formed between the material used for the electron-supply layer in the OLED and the base molecule, and that the resulting polarization ...
