2022年12月30日 · The chemical compositions of the optimized sample (i.e., HfB 2 -1PEG2000) are determined via X-ray photoelectron spectroscopy (XPS) and the corresponding results are …

Here, we highlight the synthesis and electrocatalytic properties of HfB2-based electrocatalysts as Hf1-xTMxB2 (TM = Ni and Co; x = 0.1, 0.2, and 0.3) for both hydrogen and oxygen evolution...

2022年5月1日 · Reinforced by a novel pre-annealing strategy, the SSA embraces a high solar absorptance of 93.2% and suppressed thermal emittance of 8.9%, as well as a direction …

Hafnium diboride (HfB2) is a kind of transition metal boride, which has a high melting temperature, high heat resistance, and electrical conductivity.6,7 Most importantly, HfB2 has also been …

2000年10月1日 · X-ray photoelectron spectra of a clean, well-ordered HfB 2 (0001) single crystal surface are reported. A survey spectrum covering a binding energy range of 0 to 1000 eV is …

An ordered surface structure formed after exposure of the HfB2 (0001) surface at 800 °C to SiH4 (g) followed by annealing at 900 °C has been characterized experimentally with low-energy …

For HfB2 single crystals grown at NIRIM [30], a bulk oxygen impurity of 120 ppm was found. Clear evidence that the residual oxygen signals observed with XPS are not due to oxygen …
