We report on low-temperature scanning tunneling spectroscopy measurements on epitaxial graphene flakes on Au(111). We show that using quasiparticle interference (QPI) mapping, we can discriminate between the electronic systems of graphene and Au(111). Beyond the scattering vectors, which can be ascribed to the elastic scattering within each of the systems, we observe QPI features related to the...

UNLABELLED Our objective was to evaluate the toxicity of the anti-CD33 monoclonal antibody HuM195 modified with peptides (CGYGPKKKRKVGG) harboring the nuclear localizing sequence (NLS; underlined) of simian virus 40 large T antigen and labeled with (111)In against acute myeloid leukemia (AML) cells. METHODS HuM195 was derivatized with sulfosuccinimidyl-4-(N-maleimidomethyl)-cyclohexane-1-carb...

Abstract AIMS To report a six-year experience with computerized neuro-navigation assistance in our neuro-oncology surgeries and services. METHOD Retrospective review of all consecutive cases involving computer-assisted diagnostic resective brain tumour operation over period (January 2016-December 2021). Main study parameters: Clinical procedures, operations, histological diagnosis, adjuvant tre...

Peierls distortion path was proved experimentally for dense ZnO nanoparticles prepared by static compression. Electron irradiation caused rock salt (R) to wurtzite (W) transition, following preferential (111)(R)//(0111)(W); [011](R)//[1213](W) and then transformation strain induced (111)(R)//(1011)(W); [011](R)//[0111](W). The two relationships can be rationalized by specified extent of chair- ...

The current state of understanding of the structure of the metal/thiolate interface of n-alkylthiolate 'self-assembled monolayers' (SAMs) on Cu(111), Ag(111) and Au(111) is reviewed. On Cu(111) and Ag(111) there is now clear evidence that adsorbate-induced reconstruction of the outermost metal layer occurs to a less atomically-dense structure, with the S head-group atom bonded to four-fold and ...

We study the structure and formation energy of kinks in 1/2a<111> screw dislocations in metallic Tantalum using molecular dynamics with a first principles based many-body interatomic potential. In our study, four a/3<112> kinks are in a quadrupole arrangement in the simulation cell. We impose periodic boundary conditions in the directions perpendicular to [111] and fixed boundaries in the [111]...

We present a first principle density functional study of phenylalanine interacting with three different classes of surfaces, namely a purely repulsive hard wall, mildly interacting close packed surfaces of group 11 metals (Cu(111), Ag(111), and Au(111)), and strongly interacting close packed surfaces of group 10 metals (Ni(111), Pd(111), and Pt(111)). In particular, we characterize, by changing...

Using ab initio methods, we have investigated the structures and stabilities of Si(N) clusters (N ≤ 24) on Ag(111) surface as the initial stage of silicene growth. Unlike the dome-shaped graphene clusters, Si clusters prefer nearly flat structures with low buckling, more stable than directly deposition of the 3D freestanding Si clusters on Ag surface. The p-d hybridization between Ag and Si is ...
