Antibacterial properties of Ag and Ag/AgCl nanoparticles from radish and tea extracts for water treatment applications

Silver nanoparticles (AgNPs) have antibacterial properties and are widely used for water disinfection. This technology is commercially applied in point-of-use water treatment as a post-treatment for filtrate water. However, the current process of synthesizing AgNPs has several disadvantages including the use of hazardous chemicals, consumption of a large amount of energy and the formation of ...

Chronic gamma-irradiation effect on Drosophila melanogaster lifespan in generations of wild-type isogenic and heterogenic strains

The dynamics of lifespan in 14 successive generations after chronic ͏-irradiation in heterogenic (Canton-S) and isogenic (Oregon-R spa) Drosophila wild-type strains were investigated. The γ-source was 226Ra at a dose rate of 60 cGy per generation. After chronic irradiation in the heterogenic line Canton-S, the cyclic lifespan oscillations disappeared after the fifth generation, and the values of ...

The regularity of wind-induced sediment resuspension in Meiliang Bay of Lake Taihu

Contaminants released by wind-induced sediment resuspension could influence the water quality in shallow lakes. This study aims to reveal the quantitative relationship between wind speed (v) and sediment resuspension rate (r) in Meiliang Bay of Lake Taihu. The study was conducted in three steps. First, the in situ wind speed and current velocity were measured over a period of 2 days in Meiliang ...

Battling the waste sector´s common enemy: moisture content

Moisture content has always been a barrier to maximizing profit from many waste streams. The problematic moisture content is mainly contained in the cell structure of organic materials. Conventional mechanical and thermal dryers like belt, drum, and liquidized bed dryers can’t open the cell structures of organic material and remove the moisture inside. Any dryer with mechanical pulverizing ...

Comparing the Performance of Recirculating Cyclones Applied to the Dry Scrubbing of Gaseous HCI with Hydrated Lime

Recirculating cyclone systems, combining a numerically optimized reverse ﬂow gas cyclone (RS_VHE geometry) with a straight-through cyclone concentrator, were employed as reaction chambers for the dry scrubbing of gaseous hydrogen chloride with solid hydrated lime particles. The performance of this technology was tested at laboratory scale with two differently sized RS_VHE cyclones (0.020 ...
