Edge contacts offer a significant advantage for enhancing the performance of semiconducting transition metal dichalcogenide (TMDC) devices by interfacing with the metallic contacts on the lateral side, which allows the encapsulation of all of the channel material. However, despite intense research, the fabrication of feasible electrical edge contacts to TMDCs to improve device performance remains a great challenge, as interfacial chemical characterization via conventional methods is lacking. A major bottleneck in explicitly understanding the chemical and electronic properties of the edge contact at the metal-two-dimensional (2D) semiconductor interface is the small cross section when characterizing nominally one-dimensional edge contacts.

Acenes are an important class of polycyclic aromatic hydrocarbons that have gained considerable attention from chemists, physicists, and material scientists, due to their exceptional potential for organic electronics. They serve as an ideal platform for studying the physical and chemical properties of sp carbon frameworks in the one-dimensional limit and also provide a fertile playground to explore magnetism in graphenic nanostructures due to their zigzag edge topology. While higher acenes up to tridecacene have been successfully generated by means of on-surface synthesis, it is imperative to extend their synthesis toward even longer homologues to comprehensively understand the evolution of their electronic ground state.

Hollandite-type α-MnO exhibits exceptional promise in current industrial applications and in advancing next-generation green energy technologies, such as multivalent (Mg, Ca, and Zn) ion battery cathodes and aerobic oxidation catalysts. Considering the slow diffusion of multivalent cations within α-MnO tunnels and the catalytic activity at edge surfaces, ultrasmall α-MnO particles with a lower aspect ratio are expected to unlock the full potential. In this study, ultrasmall α-MnO (<10 nm) with a low aspect ratio (c/a ≈ 2) is synthesized using a newly developed alcohol solution process.

-Armchair graphene nanoribbons (nAGNRs) are promising components for next-generation nanoelectronics due to their controllable band gap, which depends on their width and edge structure. Using non-metal surfaces for fabricating nAGNRs gives access to reliable information on their electronic properties. We investigated the influence of light and iron adatoms on the debromination of 4,4''-dibromo--terphenyl precursors affording poly(-phenylene) (PPP as the narrowest GNR) wires through the Ullmann coupling reaction on a rutile TiO(110) surface, which we studied by scanning tunneling microscopy and X-ray photoemission spectroscopy.

Aims And Objectives: Dynamic incursion of lumbrical muscle proximal to the distal edge of transverse carpal ligament (TCL) has been long debated for its role in causing median nerve compression in the carpal tunnel. This study aims to evaluate the pattern of lumbrical incursion into the carpal tunnel in various finger positions and determine their extent of presence and relationship with respect to the TCL and to each other in the carpal tunnel.
Materials & Methods: Dissection of 30 fresh frozen cadaveric hands was done to map the lumbrical muscles.
