text: "ABSTRACT\r\n \r\n Additive
manufacturing by laser powder bed fusion enables complex AlSi10Mg components but
produces a heterogeneous microstructure prone to localized corrosion. In this
study, hydrophobic polydimethylsiloxane (PDMS) ultrathin films, with and without
an SiO\r\n ₓ\r\n interlayer
attached by chemical vapor deposition (CVD), were applied for corrosion mitigation.
Surface modifications were characterized by X‐ray photoelectron spectroscopy (XPS),
polarization modulation–infrared reflection–absorption spectroscopy (PM‐IRRAS)
and water contact angle (WCA) measurements. Electrochemical behavior was evaluated
by electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV),
and chronoamperometry by a droplet‐cell approach. Atmospheric corrosion processes
simulating marine corrosion were monitored by optical microscopy. Spectroscopic
analyses confirm successful PDMS attachment. Electrochemical measurements reveal
reduced corrosion current densities by one magnitude, suppressed pitting activity,
and anodic shifts of the pitting potential. The SiO\r\n ₓ\r\n
\ ‐CVD + PDMS bilayer exhibits the highest resistance to atmospheric
corrosion.\r\n "

text: Calcium-Silicate-Hydrates (C-S-H) are the main binding phases in most concrete
which is the primarily used composite construction material in the world. However,
a big lack is cleaving between the actual knowledge about C-S-H, compared to what
could be reached using state-of-the-art technologies of modern research. In this
article, the formation of a C-S-H phase on a native oxide covered silicon wafer
is investigated by means of in-situ attenuated total reflection infrared (ATR-IR)
and ex-situ surface-enhanced Raman spectroscopy (SERS). The total thickness of
the C-S-H phase is determined by X-ray photoelectron spectroscopy (XPS) to be
3 nm. The formation appears to be reversible depending on the environment pH value
and can be performed at room temperature. Based on density functional theory (DFT)
calculations, it is shown that the C-S-H phase in the presence of water will change
its chemical composition in order to reach the thermodynamic ground state of the
system. This change is achieved by a metal-proton exchange reaction. The stoichiometry
of these metal-proton exchange reactions is nearly independent of the environment
pH value. Electrokinetic measurements yield isoelectric points of 2.0 and 2.6
for the native oxide covered silicon wafer (SiO2) and the C-S-H phase. This is
consistent with a predominance of Si-O sites at the C-S-H/water interface. (C)
