3.Ion Drift 离子偏移 The ions are then deflected by a magnetic field into a curved path. The radius of their path is dependant on the charge and mass of the ion. 这些离子被磁场偏转成一条弯曲的路径。它们的半径取决于离子的电荷和质量。 4. Detection 检测 When the positive ions hit the neg...
Chinese (本大题共 1 个小题,共 25 分) 7.At equilibrium, these two rate are equal; cupric ion is still reacting with ammonia molecules to form the complex, and the complex is still decomposing, but just as much cupric ammonia complex is being decomposed in unit time as is being formed....
The distance between the two atoms is 2.08 angstrom. This interaction reduces the charge on the imidazole motif in the zwitterion form. However, the positive charge on the imidazole ring is partially compensated with a benzene ring (the two rings are parallel). This is the reason why the O ...
The δ65Cu of the Kohistan hornblendites show a significant positive correlation with Al2O3 (Fig. 12B), suggesting that partial melting was a causal factor in Cu isotope fractionation. Partial melting of the Kohistan and Gandgese lower crust is supported by geological evidence, where some ...
3a–c). We then tested whether the capsaicin-induced increase in phagocytic capacity of tolerant microglia might reduce the level of phosphorylated α-synuclein in MAP2-positive primary cortical neurons. The levels of p-α-syn (Ser129) induced by PFF in primary cortical neurons were significantly...
The need for efficient ammonia synthesis is as urgent as ever. Over the past two decades, many attempts to find new catalysts for ammonia synthesis at mild conditions have been reported and, in particular, many new promoters of the catalytic rate have been introduced beyond the traditional K an...
1笔记 共1个版本 摘要原文 Abstract Metal additive manufacturing (AM), also known as 3D printing, is a disruptive manufacturing technology in which complex engineering parts are produced in a layer-by-layer manner, using a high-energy heating source and powder, wire or sheet as feeding material....
Guided by gut sensory cues, humans and animals prefer nutritive sugars over non-caloric sweeteners, but how the gut steers such preferences remains unknown. In the intestine, neuropod cells synapse with vagal neurons to convey sugar stimuli to the brain
Short-chain fatty acids (SCFAs), which have anti-inflammatory characteristics and can enhance gut barrier function, can also be produced by prebiotics106. Prebiotics’ interaction with the gut microbiota is one of the molecular processes behind the positive benefits of prebiotics127. Prebiotics can ...
