Researchers at Leipzig University have developed a new process for reversing the polarity of chemical compounds, also known as umpolung, for the precise synthesis of pharmaceuticals. "This ...

This is what causes atoms to bond and what holds a molecule together. Electrons can be shared unequally in a molecule, creating a polar molecule. Opposite polar ends of molecules attract and hold one ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

Alcohol has one O–H bond which is polar, but a large portion of the molecule is made up of C–H bonds which are nonpolar. Alcohol molecules do not attract each other as strongly as water molecules and ...

When a charged object such as a rubber balloon is brought close to a fine stream of a polar liquid, the stream is attracted toward the electrical charge. If the same charged object is brought close to ...

Frizzled (Fz)/planar cell polarity (PCP) signalling is a conserved mechanism regulating the polarity of cells along the axes of a tissue. Fz/PCP regulates a diverse array of processes including ...
