There were obvious Cu-rich, Ti-poor, and Zr-poor areas inside the pits, and the element distribution was not homogeneous, so the passive film formed on the surface was relatively weak and prone to corrosion. For the TCN and TN samples, the pits mainly showed a long and narrow shape ...
NaCl is a neutral compound as it has a pH value of 7. It is neither acidic nor basic in nature. NaCl is neutral as it is formed by the neutralization reaction of HCl (strong acid) and NaOH (strong base). The strong acid and strong base in the aqueous solution neutralize each other ...
though the concentration of several ions, acids/bases, etc. may change slightly during the reaction, the buffer maintains the pH by countering these effects. Buffers can be obtained in acidic conditions (pH < 7) or basic conditions (pH > 7) depending on the composition o...
LiCl, NaCl and/or KCl and (b) (1) salts of weak inorganic bases with strong inorganic acids, in particular AlCl 3 , FeCl 3 , TiCl 4 , SbCl 5 , CaCl 2 , FeCl 2 , CuCl 2 , ZnCl 2 and/or MoCl 5 (2) and/or the ... K Sirinyan,HJ Laue,R Merten,... - US 被引量: 16...
The Raman wavenumber of the symmetric stretching vibration of carbonate ion (ν1-CO32−) was measured in three aqueous solutions containing 2.0 mol·L−1 Na2CO3 and 0.20, 0.42, or 0.92 mol·L−1 NaCl, respectively, from 122 to 1538 MPa at
A buffer solution is described as an aqueous solution composed of a weak base and its conjugate acid, or vice versa. This is used to maintain the pH range of a solution upon the addition of small amounts of acid or ...
When the bias voltage is low, the energy of sputtering ions is weak, and the thermal effect that is created by the deposition process is minimal as well. In addition, the film is deposited at a fast pace, and the surface diffusion is not adequate to relieve the rapid buildup of local ...

To analyze these spectral changes, the Raman OH stretching bands are fitted with two sub-bands, denoted as (HB)s and (HB)w, representing strong (around 3220 cm−1) and weak hydrogen-bonded (around 3450 cm−1) structural components, respectively (Figure 2). Although a larger number of...
However, as revealed above by SKPFM, the micro-galvanic corrosion between the Mg2Ge phase and the α-Mg matrix should be weak. Herein, caution should be paid because SKPFM measurement was carried out in air, while the corrosion test was performed in aqueous solution. Moreover, the potential ...
