Kantavien teräsrakenteiden palosuojaus: Palosuojamaalaamalla paloluokissa R30-R120

, 2023
In this thesis, the fire protection of load-bearing steel structures and their costs are investigated. Steel is a non-combustible material, but when the temperature rises, it loses its material properties significantly. Because of this, load-bearing steel structures often need to be fireproofed.

METAL-SEMICONDUCTOR FLUCTUATION IN THE SN ADATOMS IN THE SI(111)-SN AND GE(111)-SN (ROOT-3X-ROOT-3)R30-DEGREES RECONSTRUCTIONS

, 1995
The two components of the Sn 4d core level in the Si(111)-Sn and Ge(111)-Sn. (root 3 X root 3)R30 degrees structures are proposed to arise from semiconductor-metal fluctuations in the Sn adatom layer.

The atomic structure of the Si(111) (2 root 3x2 root 3)R30 degrees-Sn reconstruction

, 1996
We have studied the atomic structure of the (2 root 3x2 root)R30 degrees reconstruction induced by adsorption of about 1.1 monolayers of Sn on Si(lll) using surface X-ray diffraction (SXRD) and scanning tunnelling microscopy (STM).

Structural and electronic properties of the Sn/Si(111)-(2 root 3x2 root 3)R30 degrees surface revised

, 2004
The Sn/Si(111)-(2root3 x 2root3)R30 degrees surface has been reinvestigated with low temperature STM/STS and high resolution core level and valence band photoemission using synchrotron radiation.

A photoelectron diffraction study of the Pd{111}(√3 × √3)R30°-CO chemisorption phase

, 1997
Using scanned-energy mode photoelectron diffraction we show that in the Pd{111} (√3 ×√3)R30°-CO phase fee hollow sites are occupied with a carbon-Pd layer spacing of 1.27 (±0.05) Å.

A low-energy electron diffraction analysis of the R30° structure of molecular nitrogen adsorbed on Ru(0001)

, 1994
The structural parameters of the R30° overlayer formed by N2 adsorption on Ru(0001) have been determined by a LEED IV analysis. The N2 molecules are coordinated to the surface at on-top sites with the interatomic axis perpendicular to the surface.

Electronic Structure of the Conjugate Honeycomb-Chained-Trimer Model for the Au/Si(111)-(root 3 x root 3)R30 degrees Surface

, 2019
Based on density-functional theory calculations, we have examined the electronic structure of the conjugate honeycomb-chained-trimer model previously proposed for the Au/Si(111)-(root 3 x root 3)R30 degrees surface, For the optimized atomic structure, we

Structure determination of Ag(111)(root 3X root 3)R30 degrees-Sb by low-energy electron diffraction

A quantitative structure determination of the Ag(111)(root 3 x root 3)R30 degrees-Sb surface has been performed using low energy electron diffraction. Six possible structural models were tested: Sb overlayers with four different adsorption sites and a ...
