Methylammonium-free, high-performance, and stable perovskite solar cells on a planar architecture
Science, 2018Staying in the black phase Hybrid perovskite solar cells often use the more thermally stable formamidinium (FA) cation rather than methylammonium, but its larger size can create lattice distortion that results in an inactive yellow phase.

An embedding of a space Y into the 3-sphere S 3 is said to be strictly achiral if its image is pointwise fixed by an orientation reversing homeomorphism of S 3 . A space Y is said to be abstractly planar if it can be embedded into the 2-sphere S

Recent developments in planar electrochromatography (PEC) in both the normal-phase and the reversed-phase modes, and at both atmospheric and elevated pressure, are reviewed. Other forced-flow techniques in planar chromatography are also briefly covered.

A finite partially ordered set (poset) P is customarily represented by drawing a small circle for each point, with a lower than b whenever a < b in P, and drawing a straight line segment from a to b whenever a is covered by b in P (see, for example, G. Birkhoff [2, p. 4]). A poset P is planar if such a diagram can be drawn for P in which none of the

PlaneNet: Piece-Wise Planar Reconstruction from a Single RGB Image
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018This paper proposes a deep neural network (DNN) for piece-wise planar depthmap reconstruction from a single RGB image. While DNNs have brought remarkable progress to single-image depth prediction, piece-wise planar depthmap reconstruction requires a ...
