Congratulations to Bobin, Zhenbin, and company! Their paper, “Relative Mechanical Strengths of Weak Bonds in Sonochemical Polymer Mechanochemistry,” has been published at J. Am. Chem. Soc. The paper provides new sonochemical methods for quantifying the mechanical force necessary to break covalent bonds, and applies it to a series of putative weak bonds along polymer backbones.
