Plastics that can metabolize in oceans are highly sought for a sustainable future. In this work, we report the noncovalent synthesis of unprecedented plastics that are mechanically strong yet metabolizable under biologically relevant conditions owing to their dissociative nature with electrolytes. Salt-bridging sodium hexametaphosphate with di- or tritopic guanidinium sulfate in water forms a cross-linked supramolecular network, which is stable unless electrolytes are resupplied.

Aim: Our aim was to evaluate the effect of conventional ICSI and Piezo-ICSI with bull or human sperm on bovine oocyte activation and embryo development and to assess its relationship with the phospholipase C zeta (PLCɀ) activity of both species.
An 80-year-old woman had developed a slight fever and loss of appetite since October 20XX. In November of the same year, the patient visited our hospital. Peripheral blood tests revealed the presence of atypical lymphocytes and a significant increase in sIL-2R.
View Article and Find Full Text PDFFluorinated cycloparaphenylenes (FCPPs) have attracted attention as electron-accepting CPPs as well as strained fluoroarenes. Herein, we report the synthesis and properties of novel FCPPs; F[8]CPP and F[6]CPP. Furthermore, the derivatization of F[8]CPP afforded a new carbon nanoring where sixteen pyrrole rings are densely substituted on the CPP framework.
