Characterization of Internal Oxidation in Alloy 690 [PDF]

, 2018
The oxidation behavior of Alloy 690 was investigated after exposure in hydrogenated steam at 480 °C. The alloy underwent internal oxidation intragranularly, resulting in the expulsion of Ni to the surface. Protective external Cr-rich oxides formed around

Potential‐Controlled Ammonium‐Assisted Reversible Electrodeposition of Polyoxometalates for Hybrid Redox Flow Batteries

Advanced Science, EarlyView.
Potential‐controlled NH4+‐assisted reversible electrodeposition of molecular metal oxide clusters enables dynamic solution‐to‐solid electron storage. Leveraging this deposition/dissolution reaction chemistry, polyoxometalate‐based hybrid flow batteries are demonstrated as a new platform for deposition‐based electrochemical energy storage.

Water‐Soluble Luminescent Trityl Radical for Fluorescence/Magnetic Resonance Dual‐Modal Imaging Probe

Advanced Science, EarlyView.
Stable water‐soluble luminescent tris(2,4,6‐trichlorophenyl)methyl (TTM) radicals, TTM‐trisTP3B and TTM‐trisTP9B, were designed and successfully synthesized. They exhibited deep‐red emissions and high photostability in water. TTM‐trisTP3B exhibited dual functionality as a fluorescence imaging (FI) probe and a magnetic resonance imaging (MRI) contrast ...

Dynamic Shear Characteristic and Fracture Feature of Inconel 690 Alloy under Different High Strain Rates and Temperatures

Advances in Materials Science and Engineering, 2013
The high strain shear rate behaviour of Inconel 690 alloy was investigated by using the split Hopkinson torsional bar. The shear strain rates were tested at 900 s−1, 1900 s−1, and 2600 s−1 and at temperatures of −100°C, 25°C, and 300°C, respectively.

Embrittlement of Hydrogen-Charged Alloy 690 Single Crystal.

Journal of Society of Materials Engineering for Resources of Japan, 1995
The effects of charging temperature and time on the embrittlement of cathodically hydrogen-charged specimens were investigated by tensile test and scanning electron microscopic studies on Alloy 690 single crystals with ‹100› tensile axis. Many cracks on the specimen surface were observed along {100} traces.

Coordinated Electronic‐Transport Regulation and Multiscale Phonon Scattering in Sb–La Co‐Doped GeTe

Advanced Science, EarlyView.
Synergistic Sb–La co‐doping simultaneously regulates hole concentration and creates strain‐field fluctuations and multiscale structural disorder in GeTe. Electrical transport is preserved, while electronic and lattice thermal conductivities are strongly suppressed.

Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression

Advanced Science, EarlyView.
A synergistic phosphor‐sensitization strategy (PSS) significantly enhances ternary OSCs performance. By integrating an Ir‐3 complex as a triplet energy mediator within a pyrazine‐based (N2) ternary blend (PM6:N2: L8‐BO) doped with 1 wt.% of Ir‐3 complex, and a PCE of 18.6% is achieved through efficient triplet‐triplet energy transfer (TTET), suppressed
