Euler's Flycatcher - eBird
Medium-sized flycatcher found in the understory and borders of humid forests. Note two conspicuous buffy wingbars framed with black and contrasting with a brown back, a gray-brown breast, and a buff belly. The lower mandible is paler than the upper. Similar to Fuscous Flycatcher, but without a prominent eyebrow.
Euclid, the Crow - Scienticity
The fiercely intelligent-looking bird is a crow by the name of "Euclid Cornwallis vanderKroew", or simply "Euclid" for short. More specifically, he is an American Crow, Corvus brachyrhynchos. The American Crow is distinctly North American. Distinctively, it is entirely black, from its iridescent black feathers to its black legs, feet, and bill.

氯化铕 - 百度百科
三氯化铕是一种有机物,化学式为EuCl3,为黄色的固体,溶于水和乙醇。 它有强烈的吸水性,无水物暴露在潮湿的空气中时会迅速吸水转变为白色结晶六水合物(EuCl3‧6H2O)。 [3] 1.性状:六方针状晶体。 2. 密度(g/mL,25℃):4.89。 4. 熔点(ºC):623。 5. 溶解性:溶于水 [1]。 可溶于水,溶液对甲基橙显中性,对石蕊显酸性。 高温下分解生成EuCl2和Cl2。 将氧化铕在含有S2Cl2的Cl2气流中加热,或将氧化铕溶解于浓盐酸中,将其水溶液在水浴上蒸发、浓缩,冷 …
<br>在 EuCl2 化合物中发现创纪录的低温磁热效应 ... - X-MOL
2024年12月4日 · 在这里,我们报道了正交 EuCl2 中的巨型 MCE,其中通过将从头开始计算与布里渊函数分析和磁性测量相结合,证明了具有优异的 Eu2+ 单离子行为和自由自旋的铁磁基态。 因此,创纪录的 −ΔSM ∼ 74.6 J·kg–1·实验实现了 5 T 时的 K–1 (1.8 K),接近理论极限的 96% (77.5 J·kg–1·K-1)。 在 1 T 的较低磁场下,EuCl2 还达到了 −ΔSM ∼ 36.8 J·kg–1·K-1.此外,直接的准绝热退磁测量表明,其较大的 −ΔSM 使 EuCl2 能够在亚开尔文温度 (∼346 mK) 下 …
