The dual-defective SnS2 monolayers: promising 2D photocatalysts for overall water splitting

Photocatalytic water splitting on the dual-defective SnS2 monolayer is a promising way to produce hydrogen fuel from solar energy.

Dual-defective strategy directing in situ assembly for effective interfacial contacts in MoS2 cocatalyst/In2S3 light harvester layered photocatalysts

Directed by a novel strategy of dual-defective construction, both enhanced reactivity and considerable photostability are achieved in layered MoS2/In2S3 photocatalysts with intimate interfacial contact and rich active sites.

Varieties with quadratic entry locus, II

We continue the study, begun in [F. Russo, Varieties with quadratic entry locus. I, Preprint (2006), math. AG/0701889] , of secant defective manifolds having ‘simple entry loci’. We prove that such manifolds are rational and describe them in terms of tangential projections. Using also the work of [P. Ionescu and F. Russo, Conic-connected manifolds, Preprint (2006), math. AG/0701885], their classification is reduced to the case of Fano manifolds of high index, whose Picard group is generated by the hyperplane section class. Conjecturally, the former should be linear sections of rational homogeneous manifolds. We also provide evidence that the classification of linearly normal dual defective manifolds with Picard group generated by the hyperplane section should follow along the same lines.
