Humans are not unique: difficult birth is common in placental mammals
Biological Reviews, EarlyView.ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain
Chemistry – A European Journal, EarlyView.Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

Lithium Metal Anode Fabrication: Methods, Challenges, and Strategies
EcoEnergy, EarlyView.Schematic illustration of four representative fabrication techniques for thin lithium metal anodes: extrusion, molten lithium infusion, electroplating, and physical vapor deposition (PVD). ABSTRACT The pursuit of ultra‐high energy‐dense lithium‐metal batteries (LMBs) has reignited the drive to fabricate ultrathin high‐quality lithium metal anodes. This
