Largely Tunable Band Structures of Few-Layer InSe by Uniaxial Strain.

Because of the strong quantum confinement effect, few-layer γ-InSe exhibits a layer-dependent band gap, spanning the visible and near infrared regions, and thus recently has been drawing tremendous attention. As a two-dimensional material, the mechanical flexibility provides an additional tuning knob for the electronic structures. Here, for the first time, we engineer the band structures of few-layer and bulk-like InSe by uniaxial tensile strain and observe a salient shift of photoluminescence peaks.

Case report: dermatomyositis associated with lung cancer with heterogeneous morphology.

Dermatomyositis (DM) complicated with non-small cell lung cancer (NSCLC) is not rare, and could rapidly develop into severe lung cancer [performance-status score (PS) between 2 and 4]. Moreover, tumor has remarkable heterogeneity, and it is not possible to properly target treatments in cases of relapse without knowing pathological diagnosis. We retrospectively analyzed the diagnosis and treatment of a patient with DM complicated with NSCLC, which developed into severe lung cancer with heterogeneity of the tumor during chemotherapy.

OsJAZ1 Attenuates Drought Resistance by Regulating JA and ABA Signaling in Rice.

JAZ (JASMONATE ZIM-domain) proteins have been reported to play negative roles in JA signaling. However, direct evidence is still lacking that JAZ proteins regulate drought resistance.

Hierarchical Surface Patterns upon Evaporation of a ZnO Nanofluid Droplet: Effect of Particle Morphology.

Surface structures with tailored morphologies can be readily delivered by the evaporation-induced self-assembly process. It has been recently demonstrated that ZnO nanorods could undergo rapid chemical and morphological transformation into 3D complex structures of Zn(OH) nanofibers as a droplet of ZnO nanofluid dries on the substrate via a mechanism very different from that observed in the coffee ring effect. Here, we have investigated how the crystallinity and morphology of ZnO nanoparticles would affect the ultimate pattern formation.
