Abstract
Let $R$ be a ring with identity and let $\mathcal{M}_R$ be the category of right $R$-modules. In this article, we study some relations between torsion theories and cotorsion theories in $\mathcal{M}_R$. As applications, we give some new characterizations of IF rings with essential flat envelopes.
