1997年6月10日 · The synthesis, characterization, and reactivity of a series of neutral and cationic Zr alkyls supported by DAC (deprotonated 4,13-diaza-18-crown-6) ligation are reported. Reaction of H2DAC with Zr(CH2Ph)4 affords a 1:4 mixture of cis- and trans-Zr(DAC)(CH2Ph)2 (cis-/trans-1a). The pure isomers undergo slow cis−trans isomerization in solution to regenerate the 1:4 cis:trans equilibrium ...

The DAC experiment was performed with Zr metal foils sandwiched between Au foils and compressed up to ~68 GPa. The Au foils protect the compressing diamonds and serves as a quasi-PTM, namely the Zr metal sample is compressed as if no PTM exists in the DAC, similar to the Stavrou et al. [3] experiment.

2024年6月5日 · 然而，随着速度和带宽的增加，DAC的传输距离受到了一定的限制。对于112G PAM4的单信道速率，具有CDR功能的重定时器（包括基于DSP的重定时器）是必要的。然而，需要注意的是，与Redrivers相比，复杂的重定时器可能会增加延迟并产生更高的成本。
