Application of hydrogen for rare-earth gadolinium purification and thermodynamic simulation of system

Plasma Transforming Ni(OH)2 Nanosheets into Porous Nickel Nitride Sheets for Alkaline Hydrogen Evolution

“…40−43 Emission peaks of hydrogen H β and H α spectra at 486.0 and 656.27 nm can be detected notably in the N 2 −H 2 plasma optical emission spectra, which demonstrate that ionized and activated H + are involved in the plasma. 43,44 Moreover, when H 2 is introduced into the plasma atmosphere, the intensity at 336.0 nm is significantly increased compared with that at 336.5 nm (Figure 5 and Figure S7), which proves the existence of the NH radical in plasma. 42,44 Formation of the NH radical will enhance the nitridation activity.…”

“…Figure shows the OES spectra of N 2 –H 2 and pure N 2 plasma. Emission lines corresponding to N 2 molecular ionization (280–490 and 500–750 nm) can be identified in both the spectra. − Emission peaks of hydrogen H β and H α spectra at 486.0 and 656.27 nm can be detected notably in the N 2 –H 2 plasma optical emission spectra, which demonstrate that ionized and activated H + are involved in the plasma. , Moreover, when H 2 is introduced into the plasma atmosphere, the intensity at 336.0 nm is significantly increased compared with that at 336.5 nm (Figure and Figure S7), which proves the existence of the NH radical in plasma. , Formation of the NH radical will enhance the nitridation activity. We further simulate the magnetic potential of the radio frequency plasma and calculate the corresponding axial velocity, N + density, and H + density (Figure , the calculationS equations are in the Supported Information).…”

A rare earth hydride supported ruthenium catalyst for the hydrogenation ofN-heterocycles: boosting the activityviaa new hydrogen transfer path and controlling the stereoselectivity

“…However, this property may be helpful in other application domains. 27,40,41 The conversion temperature between YH 3 and YH 2 is as high as 642 K at 101 325 Pa hydrogen pressure. 42 In spite of this, some hydrogen can be released under the conditions of hydrogenation reaction according to the pressure-composition isotherm (PCI) curves of Y-H systems.…”

Study on friction behavior of fabric–silicone rubber composites under dry/wet sliding environment

“…[ 1, 2 ] With a wider and deeper understanding of applications, the improvement in the performance of silicone rubber has become one of the most promising research hotspots. [ 3, 4 ] Researches on the sealing of components, [ 5, 6 ] high‐temperature resistance, [ 7 ] electrical conductivity, [ 8, 9 ] and flame retardant [ 10 ] have made remarkable achievements and have been successfully applied to production and life. However, due to its poor wear resistance, other excellent properties of silicone rubber are severely limited in complex application environments.…”
