The narrowest armchair graphene nanoribbon (AGNR) with five carbons across the width of the GNR (5-AGNR) was synthesized on Au(111) surfaces via sequential dehalogenation processes in a mild condition by using 1,4,5,8-tetrabromonaphthalene as the molecular precursor. Gold-organic hybrids were observed by using high-resolution scanning tunneling microscopy(More)
The controlled imprinting of surfaces with specified patterns is important in the development of nanoscale devices. Previously, such patterns were created using self-assembled physisorbed adsorbate molecules that can be stabilized on the surface by subsequent chemical bonding. Here we show a first step towards use of the bonding within a surface to(More)
PURPOSE Tracheal diverticulum (TD) is a rare, nonspecific symptom that is commonly associated with other malformations in clinical presentation and appearance on imaging. The case presented and the literature review performed highlight the importance of combining 3 D reconstruction technology and computerized Tomography (CT) results to better characterize(More)
The recoil of adsorbates away (desorption) and towards (reaction) surfaces is well known. Here, we describe the long-range recoil of adsorbates in the plane of a surface, and accordingly the novel phenomenon of reactions occurring at a substantial distance from the originating event. Three thermal and three electron-induced surface reactions are shown by(More)
A robust model-based lane detection and tracking algorithm has been studied. Initially, Dynamic programming (DP) and Hough transform are employed to detect lane boundaries. The Dynamic programming is known to be a powerful algorithm for optimal path finding on a cost field. Utilizing the intensities of edge image as costs of the DP, most likely road(More)
In this paper, the authors present a system structure for FPGA-based SOPC (system on programmable chip) design which uses an embedded processor to do scheduling to the HDL modules as its hard tasks. This kind of structure is implemented on the NIOS-II system offered by ALTERA and uses muC/OS-II as a real-time kernel in the embedded soft processor. The(More)
Organic-inorganic perovskite is a promising class of materials for photovoltaic applications and light emitting diodes. However, so far commercialization is still impeded by several drawbacks. Atomic-scale effects have been suggested to be possible causes, but an unequivocal experimental view at the atomic level is missing. Here, we present a(More)
The demand for catalyst with higher activity and higher selectivity is still a central issue in current material science community. On the basis of first-principles calculations, we demonstrate that the catalytic performance of the Pd-TiO2 hybrid nanostructures can be selectively promoted or depressed by choosing the suitable shaped Pd and TiO2(More)
The formation of additional phenyl rings on surfaces is of particular interest because it allows for the building-up of surface covalent organic frameworks. In this work, we show for the first time that the cyclotrimerization of acetyls to aromatics provides a promising approach to 2D conjugated covalent networks on surfaces under ultrahigh vacuum. With the(More)
One of the most charming and challenging topics in organic chemistry is the selective C-H bond activation. The difficulty arises not only from the relatively large bond-dissociation enthalpy, but also from the poor reaction selectivity. In this work, Au(111) and Ag(111) surfaces were used to address ortho C-H functionalization and ortho-ortho couplings of(More)
