Herein, a new approach was proposed to produce reduced graphene oxide (rGO) from graphene oxide (GO) using various oil palm wastes: oil palm leaves (OPL), palm kernel shells (PKS) and empty fruit bunches (EFB). The effect of heating temperature on the formation of graphitic carbon and the yield was examined prior to the GO and rGO synthesis. Carbonization of the starting materials was conducted...

Within impounded sections of the rivers Rhine and Meuse, epibenthic macroinvertebrate communities are impoverished and dominated by non-native invasive species such as the zebra mussel (Dreissena polymorpha) and quagga mussel (Dreissena rostriformis bugensis). In the winter of 2012 management of the water-level resulted in a low-water event in the River Nederrijn, but not in the River Meuse. Lo...

The ‘Shelter’ is a fantastic example of circular plastic house with diameter 8 m that somehow comparable to the ‘Futuro’. It was conceived by Dutch interior architect Kor Aldershoff, who developed prototype in glass-reinforced polyester (GRP) shells held on metal frame (1971). This kind unique for Netherlands and therefore great importance. meant providing home refugees Africa. light could also...

background: marine pollution is a global environmental problem that its monitoring by ideal biomonitors is of great importance. marine organisms, especially mussels, have the ability to accumulate metals from the environment they can be considered as a biomonitoring agent. methods: in this study, concentrations of heavy metals were measured in saccostrea cucullata collected from seven sites on ...

this research was conducted to evaluate the possibility using peanut shells compost as a suitable medium in cultivating ornamental plants. effect of peanut shells composts on the growth of viola tricolor and marigold was investigated during seven months. peat + perlite (with a ratio of 2:1) used as control treatment and peat replaced by 25, 50, 75 and 100 % v/v of peanut shells compost. plant g...

The strength of top-down control by consumers is predicted to decrease with latitude, but most data confirming this assumption come from latitudes <60°, while empirical studies of predation in sub-arctic and arctic marine habitats are few. A barnacle Balanus crenatus is a native foundation species in the shallow subtidal of the White Sea (65° N), hosting a diverse (250+ species) assemblage of m...
