Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction

steel research international, EarlyView.
Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Impact of combined oral contraceptives and progestin‐only pills on psychological and sexual well‐being of women with endometriosis: A systematic review

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Hormonal treatments for endometriosis (combined oral contraceptives/progestin‐only pills) do not show increased psychological or sexual risks compared with placebo. When pain is effectively controlled, these therapies appear well tolerated and may improve overall well‐being.
