It is generally accepted that the different SLM processing parameters lead to a certain extent different in relative density, microstructure, and comprehensive performance of the fabricated parts. Various parameters (such as scanning velocity, laser power, etc.) are adjusted to obtain suitable laser en...
These relative weights computed from the chemical equation are sometimes called equation weights.Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance....
Therefore, the relative Si-O bond length must necessarily increase with increasing coordination as the bonding polyhedra's size expands to fill the space, a general phenomenon that is well-represented by a recently proposed coordinated hard sphere highly mixture model18. The same situation is also ...
between the alloy and the solution; CPE2 represents the EDL capacitance at the EDL interface; L1 is an inductive component that is used to simulate the changes caused by the expansion of the active anode region; R3 represents the resistance relative to the local environmental changes near the ...
Of note, the decrease in QY when Mg-doped QDs are capped by oleic acid is consistent with the hypothesis of the role of OH groups in visible emission. The number of OH surface groups is expected to decrease if they react with oleic acid. The difference in relative intensities of the two...
The chemical compositions of the specimens were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES), and the data indicated that the relative deviation of the content of each element was less than ±5%. The alloys were heat-treated at 603 K for 16 h, held at 693 ...
针对这些样品,本研究检测了 Cr对 Mg同位素测试的干扰程度,评估了 实验室流程中 Cr和 Mg的 分离 效果,探讨了 Cr在淋洗过程中的行为.实验采用 1 mol/LHNO3 及 2 3 mLAG50W X8型阳离子树脂,仅通过一次分离纯化 便能将 Mg与 Cr等其他基质元素有效分离,且 Mg的回收率可达 99 8%,测试结果可靠.此外,Cr在...
The Fast Fourier Transformation (FFT) of the areas marked with T, M and L are inserted in Fig. 3b, which suggests that the basal plane of the T-SFs locally rotated about 3.6° relative to that of the upper and lower part in the twin. It should be noted that there is a ...
(LPSO) structures play an important role in tuning the mechanical properties of an Mg-alloy. Here, we report deformation twinning induces decomposition of lamellar LPSO structures and their re-precipitation in an Mg-Zn-Y alloy. Using atomic resolution scanning transmission electron microscopy (STEM)...
