In the rare-earth ion-doped solid-state lasers, the laser-active 4f electron is shielded from the surrounding lattice by the higher lying electrons which form a closed xenon shell with the 5s25p6 configuration. This screening greatly reduces electron–phonon coupling resulting in a very weak ...
Electronic configuration General electronic configuration of any element is written according to the given formula: {eq}\text{[Noble Gas]} \ ns^{1-2} \ np^{1-6} \ (n-1) d^{1-10} \ (n-2)f^{1-14} {/eq} Where n is the principa...
The electrode offered high sensitivity, high stability, high microporosity, the hydrophilicity of membranes and simple, compact configuration at micron range (Zhiheng et al., 2015). The high microporosity and hydrophilicity of membranes suggest the distinct advantages of short acclimation period and ...
be thus considered natural nanolaminates with a panoply of design possibilities, according to the choice of A+and M3+cations [85]. They can be divided into two groups, depending on the electronic configuration of A+cation (a noble metal from group X or XI), characterized by a closed-shell ...

(O2), the MnPc and FePc sheets will be dominantly covered by CO if the 1:1 CO/O2mixture is injected with a constant gas flow rate. In this condition, the MnPc and FePc sheets adsorbed with CO will not suffer from the poisoning effect only when it is exothermic for those CO-...

Consecutively, each Ti specimen was degreased by sonication in acetone and methanol for 30 min, followed by soaking into DI water and drying with nitrogen gas stream. The anodization process was implemented in a Teflon cell (40 mL) with a two-electrode configuration linked to DC voltage source...
In addition, the lattice mismatch between both elements implies that segregation would be more favorable than alloy formation, acting in favor of a core@shell configuration. Previous studies have reporteAdpptl.hNeansoe2g02r0e,g1,aFtOioRnPEdEuRrRiEnVgIEtWhe gas-phase synthesis of NPs of ...
Figure 10 illustrates the configuration of the micro-channel reactor. The adhesion between the catalyst and surface of the substrates were tested using a drop test [20]. Both ends of the micro-channel reactor were connected with 1/8-inch stainless steel tubes by welding. To ensure there was ...
