Mitigating Strain Accumulation in LiRuO via Fluorine Doping.

Lithium ruthenium oxide (LiRuO) is an archetypal lithium rich cathode material (LRCM) with both cation and anion redox reactions (ARRs). Commonly, the instability of oxygen redox activities has been regarded as the root cause of its performance degradation in long-term operation. However, we find that not triggering ARRs does not improve and even worsens its cyclability due to the detrimental strain accumulation induced by Ru redox activities.

Who Is Centered in the Humanitarian Response to Gender-Based Violence? A Critical Discourse Analysis of the Survivor-Centered Approach.

Since the 1990s, the international humanitarian system has developed approaches, tools, and standards for addressing gender-based violence (GBV) in emergencies premised on the survivor-centered approach (SCA). Utilizing critical discourse analysis, we explore how articulation of SCA within humanitarian discourse aligns with its stated intent to return control to survivors. The analysis reveals that humanitarian system power dynamics distort the application of SCA, leaving humanitarian service providers in charge of assessing the best course of action or severely limiting survivors' choices.

Lithium-nitrogen-hydrogen systems for ammonia synthesis: exploring a more efficient pathway using lithium nitride-hydride.

Ammonia synthesis chemistry with lithium-nitrogen-hydrogen materials is largely confined to pathways involving lithium hydride and lithium imide. Herein, we explore an alternate pathway featuring lithium nitride-hydride that shows more favorable characteristics from an activity, synthesis and cyclability perspective.

Facilitating green ammonia manufacture under milder conditions: what do heterogeneous catalyst formulations have to offer?

Ammonia production is one of the largest industrial processes, and is currently responsible for over 1.5% of global greenhouse gas emissions. Decarbonising this process, yielding 'green ammonia', is critical not only for sustainable fertilizer production, but also to unlocking ammonia's potential as a zero-carbon fuel and hydrogen store.
