Intangible drivers of tolerance shape human–elephant coexistence in Southwest China
People and Nature, Volume 8, Issue 8, Page 2763-2780, August 2026.Abstract Southwest China is home to a small but rapidly expanding population of Asian elephants (Elephas maximus), whose growth has intensified conflicts with people living in shared landscapes. These conflicts result in substantial economic losses and occasional human casualties. This coexistence paradox—where conservation success leads to significant

Insights Into the Temperature‐Dependent Oxidation Mechanism of Metallic Cerium in H2O‐N2 Atmospheres
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Metallic cerium (Ce), a widely used surrogate for actinide metals, enables mechanistic studies of reactions in complex gas environments under controlled and safer laboratory conditions. Here, the oxidation behavior of Ce in H2O‐N2 mixed atmospheres was investigated from 200°C to 350°C using in situ thermogravimetry–mass spectrometry, in situ X‐

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.
