A New Approach for Fairness Increment of Consensus-Driven Group Recommender Systems Based on Choquet Integral
It has been witnessed in recent years for the rising of Group recommender systems (GRSs) in most e-commerce and tourism applications like Booking.com, Traveloka.com, Amazon, etc. One of the most concerned problems in GRSs is to...

Linking the Cu(II/I) and the Ni(IV/II) Potentials to Subsequent Passive Film Breakdown for a Cu-Ni Alloy in Aqueous 0.5 M NaCl
Copper and copper-nickel alloys are known to form partially passive films in marine conditions, both naturally and under positive potential bias. Here, the anodic passivation behaviour of copper and of constantan (Cu54Ni45Mn1)...

Structural diversity and electronic properties of Cu(2)SnX(3) (X = S, Se)
The ternary semiconductors Cu(2)SnX(3) (X = S, Se) are found frequently as secondary phases in synthesized Cu(2)ZnSnS(4) and Cu(2)ZnSnSe(4) samples, but previous reports on their crystal structures and electronic band gaps are...
Putting High-Index Cu on the Map for High-Yield, Dry-Transferred CVD Graphene.
Oliver J Burton, Zachary Winter, Kenji Watanabe, Takashi Taniguchi, Bernd Beschoten, Christoph Stampfer, Stephan Hofmann
Feb 02, 2023
Reliable, clean transfer and interfacing of 2D material layers are technologically as important as their growth. Bringing both together remains a challenge due to the vast, interconnected parameter space. We introduce a...

Aug 21, 2018
Well-defined Cu2O nanocubes with tunable dimensions and physicochemical properties have been prepared using a simple one-pot reaction. Reduction of Cu(II) salts by ascorbic acid in the presence of PEG as a...
Abundance of Cu<sub>Zn</sub> + Sn<sub>Zn</sub> and 2Cu<sub>Zn</sub> + Sn<sub>Zn</sub> defect clusters in kesterite solar cells
Kesterite solar cells show the highest efficiency when the absorber layers (Cu ZnSnS [CZTS], Cu ZnSnSe [CZTSe] and their alloys) are non-stoichiometric with Cu / (Zn + Sn) ≈ 0.8 and Zn / Sn ≈ 1.2. The fundamental cause is so far...
