In the recent era, utmost attention is paid towards exploring the alternative source of energies, being more specific green energies. In modern days, when growing energy scarcity is a hot topic and considered as a global threat, in that context a green technology capable of sustainably addressing...

The identification of PM sources and their contribution to measured PM concentrations is crucial for the environmental policy making since the findings be able to conduce to the development of relevant legislation in order to achieve effective air quality manage. In this study, the sources of PM10...

Metallurgy and recovery of gold in electronic waste sometimes involve the reduction of tetrachloroaurate ion (AuCl4-) to elemental gold form. Currently, for the reduction of tetrachloroaurate ion, people use reducing agents such as hydroquinone and sodium borohydride. Photocatalysts of Fe3O4/SiO2...

In this study, an investigation was carried out in order to determine the potential of ordered mesoporous carbon including high ratio sucrose in its composition as a CO2 adsorbent. Structural characterizations of silica and carbon material were determined by using a scanning electron microscope (SEM...

Recent studies have indicated that PAEs (phthalic acid esters) are significant environmental pollutants with carcinogenic, teratogenic, and mutagenic effects. Urban soils can act as both a source and sink for city contaminants. This paper takes Changji, Xinjiang in Northwest China as the study area...

The present study simulates the flow and temperature fields in a street canyon caused by solar heating of road and building surfaces, in either calm and weak wind conditions. Six scenarios, formed by changing the sources of heat fluxes, the wind speed (0, 1 and 3 m s^-1) and direction (±), are...

Population growth, urbanization and anthropogenic activities are becoming a serious problem for water resources in Turkey, which necessitates their monitoring and maintenance of water quality. In this study, water quality was implemented in the Porsuk Stream in Inner Anatolia, Turkey. Water samples...

Due to the intermittent and fluctuating nature of wind and other renewable energy sources, their integration into electricity systems requires large-scale and flexible storage systems to ensure uninterrupted power supply and to reduce the percentage of produced energy that is discarded or curtailed...

Organic solvent extracts of three cyanobacterial species (Anabaena oryzae, Oscillatoria sp. and Stigonema ocellatum) were tested for antimicrobial activity against human pathogenic fungal and bacterial strains as well as for antioxidant and cytotoxic activity against human breast adenocarcinoma (MCF...

Presence of sulfide in the environment represents huge concerns to biological life. The high costs and low safety of chemical and physical removal strategies lead to finding alternative strategies. Sulfur-oxidizing bacteria (SOB) are consider a promising alternative strategy, where they play a...

Odour emissions from industrial plants affect air quality and are consequently cause of a growing number of public complaints. The control of odour represents a key issue in plant management. The starting point for an effective odour control is their objective measurement. The electronic nose...

In recent years, n-hexadecane, a component of diesel petroleum hydrocarbons, is frequently detected as the contaminant in many soils and water resources. The main aims of this study were focused on the feasibility of using the biodegradation for the removal of n-hexadecane from the soil-slurry...

The growing expectations of the population and the increasingly stringent regulations about air pollution have resulted in the need to minimize and conveniently treat the waste gas from different emission sources. The emissions from a large variety of plants, including waste and wastewater treatment...

Biological treatment is one of the most preferable strategies to complete and safe removal of pollutants. Pyrene (PY) is the first member of high molecular weight polycyclic aromatic hydrocarbons (HMW-PAHs) that represents various concerns to biological life and human health. In this study, two...

Recently, the exploration of new alternatives to common organic solvents in combination with non-conventional energy sources is a subject of intense research and development as tools for green extraction of plant-derived natural products. This paper deals with the use of low frequency ultrasound...

The school buildings in and around the city of Patras in the prefecture of Achaia, Greece, are classified on the basis of the prevailing environmental conditions and the existing human activities in the surrounding area. School buildings in urban and rural environment are investigated. The type and...

Due to the pressing necessity of switching to alternative sources of energy, fuel cells (FC) for household applications have emerged as an alternative for decentralized energy supply. Despite the advancement on technological developments, concerns on the availability of critical raw materials...

Honey is one of the most valuable foods in terms of its antioxidant nature and antioxidant activity. In this study, their botanic origins, total flavonoid content, total phenol content, the hydrogen peroxide scavenging activity (HPSA) (in terms of SC50 (µg mL-1)), ferric reducing antioxidant power...

This study investigates the usability of sewage sludge, waste from a waste water treatment facility, at the stable thermophilic temperature and different pH conditions in the biohydrogen production by dark fermentation. Without the addition of a pure hydrogen producer and nutrient source, the effect...

Biomining is the common term used to define processes that utilize biological systems to facilitate the extraction of metals from ores.
