Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption

Advanced Optical Materials, EarlyView.
ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Studies on the surface properties of CuO supported on CeO2 and γ-Al2O3 and its reaction properties for NO+CO reaction(CuO在CeO2和γ-Al2O3上的表面性质及对NO+CO反应性能的研究)

Zhejiang Daxue xuebao. Lixue ban, 2003
在色谱-微反实验装置上考察了CuO/CeO2、CuO/γ-Al2O3及CeO2改性的催化剂对NO+CO的反应性能,并用TPR、XRD、XPS、BET和NO-TPD等技术对上述催化剂进行了表征.结果表明催化剂活性的提高与铜物种在两种载体(CeO2和γ-Al2O3)上的价态(Cu2+和Cu+)、分散状态和吸附特性有关.TPR实验显示CuO在CeO2上存在两种还原物种,而在γ-Al2O3上只有一种还原物种.XPS检测表明CuO/CeO2的Cu2p3/2结合能值与Cu2+和Cu+的标准结合能基本吻合,而CuO ...
