Abstract To tackle the problem of climate change, Swiss energy strategies aim to reach carbon neutrality by 2050. However, this challenge cannot simply be solved focusing on operational performance and instead, a lifecycle evaluation. Thus, in order reduce sector’s footprint, building stakeholders need consider embodied GHG emissions construction materials. In study, parametric method was devel...
As a result of the EU policy to strengthen the European Union by encouraging free trade of building products between member countries, product standards for almost hundred building product groups were created over the past 20 years. The product standard for EPS in Civil Engineering Applications (EN 14933) came into force in March 2009. This presentation will focus first on the results of the im...
Plasma polymerisation is of great interest for modifying the surface properties of biomedical devices in order to control, for example, protein adsorption and cell attachment. In this paper we present results for plasma-polymerised acetonitrile deposited onto silicon or polystyrene substrates. The chemistry of films deposited under a range of experimental conditions was studied by X-ray photoel...
X-ray photoelectron spectroscopy (XPS) depth profiling with C60(+) sputtering was used to resolve the lithium-ion distribution in the nanometer-scale domain structures of block polymer electrolyte thin films. The electrolytes of interest are mixtures of lithium trifluoromethanesulfonate and lamellar-forming polystyrene-poly(oligo(oxyethylene)methacrylate) (PS-POEM) copolymer. XPS depth profilin...
Hexabromocyclododecane (HBCD, C12H18Br6) is the most widely used of the cycloaliphatic BFRs. In 1999, the global demand for HBCD (~16 kilotons) was more than double that of the penta-bromodiphenyl ether (~8.5 kilotons) mixture [1]. HBCD is used as thermal insulation in the building industry, and is the principal flame retardant in extruded (XEPS) and expanded (EPS) polystyrene foams [2]. Second...
Rammed earth (RE) is a low-tech recyclable building material with good heat storage and moisture absorption performance that can better maintain the stability of indoor thermal environment improve comfort. With innovations in development new technology, field rammed construction technology gradually expanding. However, deficiencies insulation traditional structures make it impossible for them t...
Rehabilitation of facades may be carried out with the application External Thermal Insulation Systems (ETICS). Their main contribution is increase energy efficiency buildings. In literature, hygrothermal, impact and fire performance studies have been on several systems different insulation materials, such as expanded polystyrene, mineral wool extruded polystyrene foam insulation. Due to growing...
The main goal of this study was to prepare and characterize ion exchangers on nanofibrous polystyrene matrix. Starting nanofibers were sulfonated and crosslinked at the same time by sulfuric acid. Strongly acidic cation exchanger was obtained in such a way. Anion exchanger was prepared by reaction of ethylene diamine with sulfochlorides on nanofibers acquired from sulfogroups. The polymer matri...
