“…[Image: see text] We have conducted nonlocal periodic density functional theory (DFT) calculations of N-heterocyclic carbenes (NHCs) adsorbed to Pd/Cu(100), Pt/Cu(100), Pd/Ag(100), and Pt/Ag(100) single atom alloys (SAAs) utilizing the nonlocal optPBE-vdW functional. NHCs with electron donating groups (EDGs) are predicted to bind more strongly to the SAA surface compared to NHCs functionalized with electron withdrawing groups (EWGs). …”

“…In alkaline electrolytes, the HOR/HER involve the activation of interfacial water by donating or abstracting protons. The structural diffusion mechanism of protons in aqueous electrolytes enables water molecules and cations located at a distance from the electrode to influence surface-mediated reactions. …”

“…In the plant-mycorrhizal fungi symbiosis, a single mycorrhizal network may interact with many plants, providing the opportunity for individual plants to cheat by obtaining nutrients from the fungi without donating carbon. Here we determine whether kin selection may favour plant investment in the mycorrhizal network, reducing the incentive to cheat when relatives interact with a single network. …”

“…The case studies focus on, among other issues, how sperm donors in Denmark, despite being subjugated to medical surveillance, experience the act of donating sperm as liberating; how sex workers in Indonesia turn to psychoactive painkillers to feel confident when approaching clients; why some anorexic patients in the United States resist prescribed antidepressant drugs; and how adolescent sex education workshops in Ecuador are appropriated by mothers to monitor their daughters and shame their ‘lying husbands’. …”
