Chemically robust functionalized covalent organic framework for the highly efficient and selective separation of bromine.

Effective sequestration of bromine holds great promise for the chemical industry's safe expansion, environmental preservation, and public health. However, attaining this goal is still challenging due to the serious drawbacks of existing adsorbents such as limited capacity, low retention efficiency, and sluggish uptake kinetics. Herein, we report a strategy-driven systematic study aimed at significantly enhancing multiple host-guest interactions to obtain functionalized covalent-organic frameworks for the efficient sequestration of bromine.

The spontaneous prelabour rupture of anunscarred uterus at 34 weeks of pregnancy.

Uterine rupture is an obstetric emergency needs immediate surgery and is associated with poor fetal & maternal outcome. Usually uterine rupture occurs at the lower segment (weakest part) if there is no history of uterine surgery. We hereby are reporting a case of spontaneous uterine rupture at fundus, at 34 weeks of gestation in a patient who has never had uterine surgery.
