The interaction of borazine (NsB,H,) with a Re(0001) surface has been studied by low energy electron diffraction (LEED), thermal desorption spectroscopy (TDS), Auger electron spectroscopy (AES) and electron energy loss spectroscopy (ELS). Two LEED patterns have been observed following borazine adsorption and annealing. One is the 2 X 2 structure, assigned to arise from atomic nitrogen. The othe...

We present the design and fabrication of a micrometer-scale electron gun for the implementation of ultrafast low-energy electron diffraction from surfaces. A multi-step process involving photolithography and focused-ion-beam nanostructuring is used to assemble and electrically contact the photoelectron gun, which consists of a nanotip photocathode in a Schottky geometry and an einzel lens for b...

Ultrathin crystalline silica layers grown on a Mo~112! substrate have been shown to be a useful silica model oxide support in surface science model catalyst studies. As the oxide support material plays an important role in the catalytic process, a multitechnique surface science study is presented to characterize the morphological and electronic properties of the heteroepitaxial system SiO2 /Mo(...

Few studies focus on researching the potential of sustainable buildings to promote sustainability their occupants. Therefore, this study aims at analyzing use LEED credits, with intention promoting pro-environmental behaviors. The methodology is exploratory in nature, a descriptive logic, and comparatively analyzes LEED-certified office [Argentina (n = 351); Chile 494); Colombia 432); Peru 282)...

Sustainability as a predominant paradigm of 21st century adopted as the best approach to tackle the issues which threat the environment and people’s well-being. As cities in the world are places in which most of the population in the world settles, the best way of ensuring sustainability would be by observing a set of rules and regulations. There are various sets of urban regulations, rating sy...
