Daylight in classrooms is a critical factor in school design, in terms of its impact on students’ health, learning and visual performance. Providing adequate amount of evenly distributed daylight and glare prevention are important challenges in classroom design. Window configuration significantly affects the intensity and uniformity of daylight. This paper aims to investigate the effect o...

The LEED pattern of clean (101) surfaces of Au show a characteristic (1 X 2) superstructure. The diffuseness of reflections in the reciprocal [OlO] direction is caused by onedimensional disorder of chains, strictly ordered into spatial [lo]] direction. There is a transition from this disordered superstructure to the normal (1 X 1) structure at 420 r 15°C. The angular profiles of the (04) and (0...

We present a combined angle-resolved photoemission spectroscopy and low-energy electron diffraction (LEED) study of the prominent transition metal dichalcogenide ${\mathrm{IrTe}}_{2}$ upon potassium (K) deposition on its surface. Pristine undergoes series charge-ordered phase transitions below room temperature that are characterized by formation stripes Ir dimers different periodicities. Suppor...

Direct growth of graphene on Co(3)O(4)(111) at 1000 K was achieved by molecular beam epitaxy from a graphite source. Auger spectroscopy shows a characteristic sp(2) carbon lineshape, at average carbon coverages from 0.4 to 3 ML. Low energy electron diffraction (LEED) indicates (111) ordering of the sp(2) carbon film with a lattice constant of 2.5(±0.1) Å characteristic of graphene. Sixfold symm...

The interaction of nitrogen with a Re(OOO1) 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 upon adsorption of nitrogen on Re(OOO1). One, identified as the 4 x 1, is induced by N, exposure at 115 K and is related to the or...

This study aimed to assess the impact of a four-point bonus system on recertification in Leadership Energy and Environmental Design for Existing Buildings (LEED-EB) 2009 office space projects four metropolitan cities: Washington, DC, Chicago, New York, San Francisco. We analyzed 123 paired LEED-EB where each pair (i.e., certification–recertification) was used same building. The percentage avera...

Reaction fronts in the O2+H2 reaction on a Rh(110) surface predosed with potassium have been shown to be associated with a redistribution of the potassium from the oxygen freed to the still oxygen covered parts of the surface. As stable final state a stationary pattern results under reaction conditions formed by K+O coadsorption islands of macroscopic size. Here low energy electron microscopy (...

The adsorption of ammonia on a monolayer of Pd on Mo(110), Pd1ML/Mo(110), and multilayer Pd(111)/Mo(110) surfaces has been studied using low-energy electron diffraction (LEED), temperature-programmed desorption (TPD), and high-resolution electron energy loss spectroscopy (HREELS). A diffuse (2 × 2) LEED pattern has been observed for ammonia on the Pd1ML/Mo(110) surface. TPD measurements indicat...
