The combined and single effect of salinity and copper stress on growth and quality of Mentha spicata plants
(2019)Copper is essential for plant growth, but in excess may cause adverse effects on plant physiology. Harmful effects are also caused by plant exposure to salinity (NaCl) due to the excessive use of fertilizers, soil degradation ... -
Copper foams in water treatment technology: Removal of hexavalent chromium
(2015)Open-cell copper foams were prepared using a space holder technique and tested as filter-beds for the uptake and reduction of Cr(VI) in drinking water. The use of raw cane sugar as a space holder provides an environmentally ... -
Electrocatalytic production of hydrogen over highly efficient ultrathin carbon encapsulated S, P co-existence copper nanorods composite
(2020)Electrocatalysis plays a key role in energy conversion processes (such as hydrogen evolution reaction-HER) to several renewable energy technologies developed to reduce our dependence on fossil fuels. It is of great importance ... -
Electronic modulation of cobalt phosphide nanosheet arrays via copper doping for highly efficient neutral-pH overall water splitting
(2020)We report here, an effective strategy to optimize the electronic structure of CoP using copper doping, for greatly enhancing the intrinsic activity and conductivity of CoP in neutral-pH water splitting. As a result, the ... -
Enhanced Ultrasonic-Assisted Heterogeneous Fenton Degradation of Organic Pollutants over a New Copper Magnetite (Cu-Fe3O4/Cu/C) Nanohybrid Catalyst
(2020)A copper magnetite nanohybrid catalyst (Cu-Fe3O4/Cu/C), abundant of Schottky interfaces and structural defects, with ultrathin encapsulation of graphitic carbon, was synthesized and tested. The catalyst shows enhanced ... -
Evaluation of toxic and interactive toxic effects of three agrochemicals and copper using a battery of microbiotests
(2009)Three commonly used test organisms of different trophic levels (Vibrio fischeri, Pseudokirchneriella subcapitata and Daphnia magna) were exposed to selected agrochemicals (fosthiazate, metalaxyl-M, imidacloprid) and copper, ... -
Finite elements analysis of cylindrical copper shelled SLA electrodes
(2010)A cylindrical copper shelled SLA electrode was modelled and analysed using the finite element method. The thickness of the silver paint is assumed to be uniform and constant around the SLA epoxy core with a value of 15 ... -
Fish farming and anti-fouling paints: a potential source of Cu and Zn in farmed fish
(2014)The accumulation of copper and zinc, the basic components of anti-fouling paints, was examined in cultured sea bass Dicentrarchus labrax and sea bream Sparus aurata. Samplings were carried out at 4 eastern Mediterranean ... -
Geo- and nano-materials affect the mono-metal and competitive sorption of Cd, Cu, Ni, and Zn in a sewage sludge-treated alkaline soil
(2019)We evaluated the effect of geomaterials (modified zeolite and bentonite using CaCl2) and nanoparticles (ZnO and MgO) on the mono-metal and competitive sorption of cadmium (Cd), copper (Cu), nickel (Ni), and zinc (Zn) in ... -
Herbal plants- and rice straw-derived biochars reduced metal mobilization in fishpond sediments and improved their potential as fertilizers
(2022)Fishpond sediments are rich in organic carbon and nutrients; thus, they can be used as potential fertilizers and soil conditioners. However, sediments can be contaminated with toxic elements (TEs), which have to be immobilized ... -
Influence of Zeolite and Posidonia oceanica (L.) in the Reduction of Heavy Metal Uptake by Tobacco (Nicotiana tabacum) Plants of Central Greece
(2017)In two soils from Central Greece, a pot experiment was conducted with the addition of mixture at various ratios of zeolite and compost (based on Posidonia oceanica (L.) leaves) applied at a rate of 5% w/w (calculated on a ... -
Interface charges redistribution enhanced monolithic etched copper foam-based Cu2O layer/TiO2 nanodots heterojunction with high hydrogen evolution electrocatalytic activity
(2019)Semiconducting materials are considered as excellent electrocatalysts for electrochemical water splitting; however, there is still a lack of relevant design and understanding of semiconducting composite electrodes. Here, ... -
