Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Experimental and theoretical investigation of three Alloy 690 mockup components: Base metal and welding induced changes [PDF]

, 2014
The stress corrosion cracking (SCC) resistance of cold deformed thermally treated (TT) Alloy 690 has been questioned in recent years. As a step towards understanding its relevancy for weld deformed Alloy 690 in operating plants, Alloy 690 base metal and ...

Controllable Topological Domain Arrays in Periodically Wrinkle‐Patterned Pb(Zr0.2,Ti0.8)O3 Thin Films

Information &Functional Materials, EarlyView.
We demonstrate reversible mechanical and electrical control of ordered center‐type topological domains in wrinkled PZT films, with high‐conductivity channels at domain cores, enabling multifield manipulation for future topological devices. ABSTRACT Ferroelectric topological domain textures hold promise as key building blocks for next‐generation ...

Mechanical Behavior of Vibration-Arc-Welded Alloy 690

Materials Transactions, JIM, 1999
To evaluate mechanical properties after stress relief, nickel base superalloy 690 was welded while subjected to synchronous mechanical vibration. In the vibrated specimen, the weld metal was seen to have fine microstructures, and low residual stress levels were measured in specimens subjected to vibration.

PTQ10‐based organic photodetectors for visible light detection and their tolerance to impurities

Polymer International, EarlyView.
PTQ10‐based organic photodetectors were found to be very sensitive to the presence of Pd(PPh3)4 catalyst traces, impacting the transport properties and light detection capacities. Abstract PTQ10 donor polymer has attracted a lot of interest in organic optoelectronics, particularly in the field of organic photovoltaics, owing to its ease of synthesis ...

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor

Progress in Photovoltaics: Research and Applications, EarlyView.
A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.
