TL;DR: The theoretical model revealed that the reconstruction of Cr2Te3 could result in anomalous thickness-dependent Tc and this dimension tuning method opens up a new avenue for manipulation of ferromagnetism.
Abstract: The manipulation of magnetism provides a unique opportunity for the development of data storage and spintronic applications. Until now, electrical control, pressure tuning, stacking structure dependence, and nanoscale engineering have been realized. However, as the dimensions are decreased, the decrease of the ferromagnetism phase transition temperature (Tc) is a universal trend in ferromagnets. Here, we make a breakthrough to realize the synthesis of 1 and 2 unit cell (UC) Cr2Te3 and discover a room-temperature ferromagnetism in two-dimensional Cr2Te3. The newly observed Tc increases strongly from 160 K in the thick flake (40.3 nm) to 280 K in 6 UC Cr2Te3 (7.1 nm). The magnetization and anomalous Hall effect measurements provided unambiguous evidence for the existence of spontaneous magnetization at room temperature. The theoretical model revealed that the reconstruction of Cr2Te3 could result in anomalous thickness-dependent Tc. This dimension tuning method opens up a new avenue for manipulation of ferromagnetism.

TL;DR: In this paper, the performance of hexagonal WO3 nanosheets with and without dominant (0 0 1) facets (Cu2O/WO3-001 and Cu2O /WO 3-3) was evaluated in the presence of H2O vapour under visible light irradiation.
Abstract: Systematical design and controllable assembly of nanostructured photocatalysts have received much attention in the field of CO2 reduction. The Cu2O decroted hexagonal WO3 nanosheets with and without dominant (0 0 1) facets (Cu2O/WO3-001 and Cu2O/WO3) were synthesized vertically on the surface of fluorine-doped stannic oxide (FTO) substrate and their photocatalytic performance for CO2 reduction were evaluated in the presence of H2O vapour under visible light irradiation (λ > 400 nm). The Cu2O/WO3-001 catalyst exhibited higher photocatalytic activity than those of Cu2O, WO3-001 and Cu2O/WO3. The maximal product yields of CO, O2 and H2 for Cu2O/WO3-001 after 24 h illumination reached 11.7, 5.7 and 0.7 μmol, respectively, and good cycling ability was discovered after 4 cycles. The (0 0 1) facet of hexagonal phase WO3 nanosheet was in favor of the H2O oxidation in the CO2 reduction process. Additionally, the Z-scheme charge transfer mode of Cu2O/WO3 heterojunction could promote photoinduced charge separation and enhance redox ability of the separated electrons and holes, leading to excellent photocatalytic CO2 reduction performance. The study may provide some insights into the coherent design of specific nanosheet photocatalysts with Z-scheme charge transfer for CO2 reduction.

TL;DR: The inelastic tunneling probe (itProbe) is used to acquire real-space imaging of intermolecular-bonding structures in the two-dimensional self-assembly of halogenbenzene molecules on a metal surface to provide a hitherto missing understanding of the nature of the halogen bond.
Abstract: Halogens are among the most electronegative elements, and the variations in size and polarizability of halogens require different descriptions of the intermolecular bonds they form. Here we use the inelastic tunneling probe (itProbe) to acquire real-space imaging of intermolecular-bonding structures in the two-dimensional self-assembly of halogenbenzene molecules on a metal surface. Direct visualization is obtained for the intermolecular attraction and the “windmill” pattern of bonding among the fully halogenated molecules. Our results provide a hitherto missing understanding of the nature of the halogen bond.

TL;DR: It is shown that every principal sub-tensor of such a structured Tensor is still a structured tensor in the same class, with a lower dimension, and the potential links of such structured tensors with optimization, nonlinear equations, non linear complementarity problems, variational inequalities and the non-negative tensor theory are discussed.
Abstract: In this paper, we extend some classes of structured matrices to higher order tensors. We discuss their relationships with positive semi-definite tensors and some other structured tensors. We show that every principal sub-tensor of such a structured tensor is still a structured tensor in the same class, with a lower dimension. The potential links of such structured tensors with optimization, nonlinear equations, nonlinear complementarity problems, variational inequalities and the nonnegative tensor theory are also discussed.
