| 1 | Superlubricity of epitaxial monolayer WS2 on graphene显示文摘We report the superlubric sliding of monolayer tungsten disulfide (WS2) onepitaxial graphene (EG) grown on silicon carbide (SIC). Single-crystalline WS2flakes with lateral size of hundreds of nanometers are obtained via chemicalvapor deposition (CVD) on EG. Microscopic and diffraction analyses indicatethat the WS2/EG stack is predominantly aligned with zero azimuthal rotation.The present experiments show that, when perturbed by a scanning probemicroscopy (SPM) tip, the WS2 flakes are prone to slide over the graphenesurfaces at room temperature. Atomistic force field-based molecular dynamicssimulations indicate that, through local physical deformation of the WS2 flake,the scanning tip releases enough energy to the flake to overcome the motionactivation barrier and trigger an ultralow-friction rototranslational displacement,that is superlubric. Experimental observations show that, after sliding, the WS2flakes come to rest with a rotation of nn/3 with respect to graphene. Moreover,atomically resolved measurements show that the interface is atomically sharpand the WS2 lattice is strain-free. These results help to shed light on nano-tribological phenomena in van der Waals (vdW) heterostacks, and suggest thatthe applicative potential of the WS2/graphene heterostructure can be extendedby novel mechanical prospects. | Holger Buch Antonio Rossi Stiven Forti Domenica Convertino Valentina Tozzini Camilla Coletti | 2018 | Nano Research2018，11，11： | 3 |
| 2 | Hepato-splenic lymphoma:a rare entity mimicking acute hepatitis:A case report显示文摘We reported a case of non-Hodgkin's lymphoma where liver involvement was the predominant clinical manifestation. A 27-year old man presented wiht markedly elevated serum aspartate aminotrasferase, alanine aminotransferase and lactate dehydrogenase, reduced prothrombin activity, thrombocytopenic purpura and hepato-splenomegaly without adenopathy. Viral, toxic,autoimmune and metabolic liver diseases were excluded.Bone marrow biopsy showed an intracapillary infiltration of T-lymphocytes with no evidence of lipid storage disease.Because of a progressive spleen enlargement, splenectomy was performed. Histological examination showed lymphomatous intrasinuses invasion of the spleen.Immunohistochemical investigation revealed the T phenotype of the neoplastic cells: CD45+, CD45RO+,CD3+, CD4-, CD8-, TIA1-. About 50 % of the lymphoid cells expressed CD56 antigen. The diagnosis of hepatosplenic T cell lymphoma was done. The patient was treated with chemotherapy, which induced a complete remission. Eighteen months later, he had a first relapse with increased aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase,thrombocytopenic purpura and blast in the peripheral blood.In spite of autologous bone marrow transplantation, he died twenty months after the diagnosis. Even in the absence of a mass lesion or lymphoadenopathy, hepatosplenic Tcell lymphoma should be considered in the differential diagnosis of a patient whose clinical course is atypical for acute hepatic dysfunction. | Federico Perfetto Roberto Tarquini Francesco Mancuso Simonetta di Lollo Silvia Tozzini Giampiero Bellesi Giacomo Laffi | 2003 | World Journal of Gastroenterology2003，9，6： | 2 |
