The three-dimensional porous Fe3O4@Cu2−xS–MoS2 framework is reported for the first time. Such a hybrid framework exhibits excellent NIR-light photocatalytic activity and stable cycling for the direct arylation of heteroaromatics at room temperature.

ABSTRACT We explore the induction of circular polarization (CP) of near-infrared light in star-forming regions using three-dimensional radiative transfer calculations. The simulations trace the change of Stokes parameters at each scattering/absorption process in a dusty gas slab composed of aligned grains. We find that the CP degree enlarges significantly according as the size of dust grains increases and exceeds ∼20 per cent for micron-sized grains. Therefore, if micron-sized grains are dominant in a dusty gas slab, the high CP observed around luminous young stellar objects can be accounted for. The distributions of CP show the asymmetric quadrupole patterns regardless of the grain sizes. Also, we find that the CP degree depends on the relative position of a dusty gas slab. If a dusty gas slab is located behind a star-forming region, the CP reaches ∼60 per cent in the case of 1.0 µm dust grains. Hence, we suggest that the observed variety of CP maps can be explained by different size distributions of dust grains and the configuration of aligned grains.

Abstract We developed a micro-manipulation technique performed under optical microscope observation, which enabled accurate fabrication of three-dimensional photonic crystals for near-infrared light. Thin GaAs plates having an in-plane pattern were picked up with a fine needle and were mechanically stacked one-by-one by using vertical posts as guides. In spite of the limited spatial resolution in the optical microscope images, the mechanical resolution of the micro-manipulator and the precisely fabricated vertical posts enabled a stacking error as small as 20 nm. Photoluminescence measurement of a nanocavity in the three-dimensional photonic crystals showed a cavity-mode peak in the near-infrared region.
