Water absorption

Public parks in cities, with most of their area being green areas, play an important role not only in balancing the living environment, but also in contributing to the minimisation of flood risks through absorption and the storing of water. This creates the motivation to restore, maintain and develop green areas in inner cities, especially in centralised areas, which have a high level of urbanisation potentially associated with a shortage of such green-lands.

In porous aquifers, the central-to-sea cross-section highlights meteoric water dominance from rain and surface sources. Groundwater undergoes exchange-absorption with silicate minerals, enriching Ca2+ and Mg2+ (reducing Na+). Seaward, dissolution and leaching of salts in marine-origin sediments (mQ2, mQ13, mQ12-3, and mN22) prevail. The results of this paper provide necessary information for the effective management of groundwater quality.

Wastes generated from healthcare practices are a serious problem for humans as well as for the environment. In this study, an attempt was made to use mixed solid medical waste (WPN) which consisted of shredded waste plastic and chopped waste needles for partial replacement of natural fine aggregate (sand) in concrete mixes at 0%, 2%, 4%, 6%, 8% and 10% by weight.

With Beech veneers being treated with 10% solid content of the chemicals from paper (Alkyl ketene dimer, AKD), wood (N-methylol melamine, NMM-1) and textile industry (fatty acid modified N-methylol melamine, mNMM-2), the results showed that the treatments with these chemicals considerably increased the water repellence effectiveness (WRE) of veneers in the initial submersion phases. In this paper, veneers treated with Nmethylol melamine and AKD chemicals were investigated on water/moisture related properties and their stability after cyclic tests.

The distinctive properties of bentonite, including hydration, swelling, water absorption, ion adsorption, high viscosity, and thixotropy make it a valuable material for many applications in geotechnical engineering such as hydraulic barriers, drilling slurry, and landfill liners. This study introduces gellan gum as a friendly environmental additive that improves bentonite slurry stability when bentonite is used for soil stabilization during excavation in emergency response.

The silver nanoparticles are synthesized by the green method using Salix semi-solid extract. Fresh leaves are prepared in a semi-solid extract form that retains active substances and can be preserved for a long time. The parameters of the synthesis process are optimized by examining the effects of pH, Salix semi-solid extract concentrations of extract and AgNO3 concentrations through the UV-Vis absorption spectrum of synthetic particulate solutions.
