Rare Metals, EarlyView.ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...

Rare Metals, EarlyView.ABSTRACT Converting CO2 to CH4 under mild conditions is a promising strategy for solving environmental and energy problems, but also a challenge. In this work, the low‐temperature CO2 hydrogenation process over Ni/CeO2 catalysts was significantly accelerated by optimizing the H2 dissociation ability of Ni through the size effect, thus A‐Ni/CeO2 with an

Rare Metals, EarlyView.ABSTRACT CsPbI3 quantum dots (QDs) have attracted considerable attention as promising candidates for light‐emitting diode (LED) applications. However, their intrinsic tendency to undergo a spontaneous phase transition to a nonperovskite structure significantly hampers their practical deployment. Considerable efforts have been devoted to stabilizing the

Rare Metals, EarlyView.ABSTRACT The covalent bonds at heterojunction interfaces enable more efficient charge carrier separation than traditional weakly coupled heterojunctions, with enhanced photocatalytic performance for organic wastewater purification. The interfacial covalent bonds drive energy band reorganization, rendering the conventional independent band edge ...

野生动物学报, 2009 2006年5月1日～7月18日,对哈尔滨北方森林动物园1对笼养灰鹤繁殖期行为进行观察,研究表明:笼养条件下,灰鹤静立（雄31.08%,雌35.81%）、理羽（雄19.81%,雌12.45%）、采食（雄13.23%,雌15.09%）行为比例较高,而繁殖行为占总行为时间比例雄鹤为2.49%、雌鹤为10.30%。灰鹤各行为日节律不明显;静立、理羽、休息和繁殖行为的发生受天气状况影响显著,尤其是静立和理羽差异极显著。灰鹤雌雄行为差异性在中期较显著,就整个繁殖期看,受天气状况的影响行为差异不显著。
