In 0.1 mol L−1 KOH, the Ptc/Ni(OH)2 has an onset overpotential of ~0 mV vs. RHE, and a significantly low overpotential of 32 mV at a current density of 10 mA cm−2, lower than that of the commercial 20% Pt/C (58 mV). The mass current density data illustrated ...
During this process, some Te NWs were anchored at the edge of the half Cu grid. W tips were prepared by electrochemically etching with NaOH solution (2 M) under a voltage of 2 V. All the W tips were cleaned by plasma cleaning for 60 s before use. The W tips were then ...

Ce(NO3)3·6H2O (1.5 g) and NaOH (15.4 g) are dissolved in 5 and 35 mL of deionized water, respectively. Then these two solutions are mixed and keep stirring for 30 min with the formation of a milky slurry. Subsequently, this mixture is transferred into a 50-mL Teflon ...
Commonly utilized routes for size-selection of clusters are electrostatic quadrupole mass filters49, radiofrequency quadrupole mass filters50, and time of flight51. To prevent the cluster fragmentation and substrate damage, researchers developed the landing technique from “hard landing” to “soft ...
Since nuclear latent tracks have diameters in the range of 10 to 1000 nm, they can be visualized by AFM with a slight chemical etching (6 min in 6 n NaOH solution at 70 掳C). These tracks are significant for the energy, momentum and the mass of the incoming particles. In our study,...
was done by either heating for 1 h at 56 °C or acid treatment, which was done by addition of 1 volume 0.1 M NaH2PO4(pH < 5) to 146S particles, incubation at room temperature for 15 min, and neutralization to pH 7.4 by ad...
