In situ tensile tests and crystal plasticity finite element modeling (CPFEM) were used to study the deformation cracking behaviors of Cr-coated Zr-4 alloys for accident tolerant fuel claddings under tension. Based on experimental results, vertical cracks in coating generally initiated from interface between substrate, expanded top surface coating. addition, large deformation, also resulted inte...

Tribological coatings of yttria stabilized zirconia (YSZ), gold, diamond like carbon (DLC) and MoS2 were synthesized using magnetron assisted pulsed laser deposition (MSPLD). The coatings were synthesized in four-component and three-component combinations that included YSZ/Au/DLC/MoS2, YSZ/Au/MoS2, and YSZ/Au/DLC. A range of coating compositions was studied to explore coating optimization for l...

We have employed attenuated total reflection Fourier transforms infrared spectroscopy sATR-FTIRSd to monitor the profile evolution of patterned mesoporous, low-dielectric-constant SiO2 films in situ and in real time during plasma etching. A stack of patterned photoresist, anti-reflective coating, and mesoporous SiO2 is etched in an inductively coupled plasma reactor, using CHF3 and Ar. During e...

In this work it is proposed a novel antibacterial surface composed of an organicinorganic hybrid matrix of tetraethoxysilane (TEOS) and a weak polyelectrolyte like Poly(acrylic acid sodium salt) (PAA) which are deposited on glass slides by sol-gel method using the dip-coating technique [1]. This work is focused in the in situ synthesis of Ag nanoparticles (NPs) which are responsible of the anti...

[1] High‐silica materials have been observed on Mars, both from orbit by the CRISM spectrometer and in situ by the Spirit rover at Gusev Crater. These observations potentially imply a wet, geologically active Martian surface. To understand silica formation on Mars, it is useful to study analogous terrestrial silica deposits. We studied silica coatings that occur on the 1974 Kilauea flow in the ...

We investigated in situ the growth of a sputter-deposited gold film (sputtering rate R = 3.2 nm/min) on top of a pre-structured colloidal polymer template using grazing incidence small-angle X-ray scattering (GISAXS [5]). The underlying colloidal polymer template was deposited by using the novel technique of airbrush-spray coating, allowing for the installation of stripe-like trapezoidal patter...
