Journal of Sustainable Construction Materials and Technologies

In this study, theophylline (1) compounds were synthesized with addition of 2-bromoetha-nol, 2-bromoacetamide and methyl-2-bromoacetate to attain symmetric connections to NHCs (2a–c). New complexes containing the symmetric N-heterocyclic carbene (NHC) ligands were synthesized using azolium salts in dimethyl formamide (DMF). After the NHC predecessor compounds reacted with Ag O, Ag(I)-NHC complexes were synthesized in the following: 7,9-di-(2-hydroxyethyl)-8,9-dihydro-1,3-dimethyl-1H-purine-2,6(3H,7H)-dionedium silver(I)bromide (3a), 7,9-di(acetamide)-8,9-dihydro-1,3-dimethyl-1H-purine-2,6(3H,7H)-di-ondium silver(I)bromide (3b) and 7,9-di(methylacetate)-8,9-dihydro-1,3-dimethyl-1H-pu-rine-2,6(3H,7H)-diondiumsilver(I)bromide (3c). Both synthesized NHC predecessors (2a-c) and Ag(I)-NHC complexes (3a-c) were described by FTIR, 1H-NMR, 13C-NMR, liquid and solid-state conductivity values, TGA analysis, melting point analysis and XRD spectroscopy.

Plaster Of Paris Containing Zero Valent Iron Particles: Designing A Permeable Reactive Barrier, Used For Remediation Of 4-Nitroaniline Pollution, Saliha Boudıa, Farida Fernane, Patrick Sharrock, Marina Fiallo

Journal of Sustainable Construction Materials and Technologies

Permeable reactive barrier (PRB) containing zero valent iron (ZVI), plaster and additives to make a porous composite structure, was tested to remove an organic nitro compound as model pollutant. An aqueous solution of 4-nitroaniline (PNA) was passed through a porous plaster column and chemical degradation quantified by UV-Vis spectroscopy. PNA was reduced to p-phenylenediamine and the rate of the reduction was strongly related to ZVI amount, pollutant volume, and the contact rate with the metal particles. The PBR could be controlled by design and operation. Test columns were made to evaluate the materials for making precast plaster blocks containing ZVI. …

Effect Of Opening Layout And Sheathing On Lateral Load Bearing Capacity In Wooden Shear Walls, Erdem Kazım Demirkıran, Nabi Volkan Gür Apr 2025

Effect Of Opening Layout And Sheathing On Lateral Load Bearing Capacity In Wooden Shear Walls, Erdem Kazım Demirkıran, Nabi Volkan Gür

Journal of Sustainable Construction Materials and Technologies

Wood is preferred as building material in earthquake zones thanks to its light-weight. In countries with high seismic activity, wooden construction systems are required to be resistant to lateral and vertical loads. In traditional architecture, lateral load resistance is ensured with filled and unfilled walls which are strengthened with braces. In present day lateral load resistance is ensured with wooden shear walls formed by sheathings covered on the wall frame. Wooden shear walls may contain openings such as windows, doors and service channels. These types of openings reduce rigidity in wooden shear walls. The opening ratio, opening location, sheathing thickness …
