Fabrication of Nano-Silver Composite Using Amomum longiligulare Fruit Polysaccharides and Their Biological Activities by Lian Y, Ma N, Cheng Q, Luo M, Xu Z, He F, Zhou X, Zhang Y, Jin D, Kong Y, Wang Y, Wei N

“…Finally, the in vitro antioxidant activity, antibacterial activity and anticancer activity of the nano-silver composite were evaluated.Results: Single-factor experiments identified the optimal synthesis conditions for ALP(D)-AgNPs as a reaction time of 180 min, a temperature of 100 °C, and a 10:1 volume ratio of silver nitrate to ALP-D. The free radical scavenging activity of ALP(D)-AgNPs against DPPH and ABTS was significantly enhanced compared with that of ALP-D. …”

Research on Performance and Mechanism of the NH3-SCR Reaction over Fly Ash-derived Mn-Ce/Zeolite X by Weijia Ren, Qi Xin, Zhesheng Hua, Zhong Zheng, Lifeng Xiao, Shaojun Liu, Chenghang Zheng, Yang Yang

“…When above 250°C, Langmuir-Hinshelwood mechanism plays a dominant role. The nitrates on the surface gradually convert to bidentate nitrates, impeding the SCR reaction, could be one of the reasons for reducing the high-temperature activity.…”

Assessment of Physicochemical Properties and Heavy Metals in Borehole Water Used For Drinking In Okada Town, Edo State, Nigeria by W.A. Raji, C.E. Anih, P.O. Obeta

“…Ten water samples labeled A-J were collected from boreholes at different locations in Okada community and subjected to laboratory test to determine the pH, biological oxygen demand (BOD), chemical oxygen demand (COD),  dissolved oxygen (DO), hardness, turbidity, total organic carbon, total dissolved solids, electrical conductivity, and concentration of phosphates, nitrates, lead, sodium, calcium and chloride. The pH in the water samples is an indication of acidity and the WHO standard for pH value is specified within the range of 6.5-8.5. …”

Impact of Municipal Solid Waste Leachate on Surface Water Quality: A Case Study on Kabuturumba Stream. by Rubarema, Paul

“…Different parameters such as COD and BOD levels were found to be extremely high than the environmental standards but later on the hypofiltration or the cleansing capacity of the wetland around the stream helped on reducing them down the stream and almost reached the environmental standards, nutrient levels such as phosphates and Nitrates were also above the recommended values, bacteriological status was extremely higher and later on reduced downstream. …”

Assessment of Variability in Physicochemical Water Parameters of Lake Nyabihoko, Western Uganda. by Abraham, Atuhaire

“…The mean values for the measured parameters of DO, EC, turbidity, TDS, chloride, and phosphates significantly differed between sampling seasons except for temperature, pH, hardness, alkalinity, calcium, magnesium, and nitrates. The lake’s Water Quality Index (WQI) values ranged from 82.9 to 88.8, with an overall mean value of 86.1, which belongs to the “very poor” class of drinking water quality based on the WQI classification. …”
