An evaluation of the efficiency of cultural plants to remove heavy metals from growing mediu
Plant, Soil and Environment, 2005 Contamination of heavy metals in the environment is one of major concern because of their toxicity and threat to human life and the environment. Phytoextraction, using plants to extract heavy metals from contaminated soils is an emerging technology.

A Comparative Analysis of Satellite‐Derived CO Retrievals During the 2020 Wildfires in North America
Journal of Geophysical Research: Atmospheres, Volume 129, Issue 22, 28 November 2024.Abstract In September 2020, the Western United States experienced anomalously severe wildfires that resulted in carbon monoxide (CO) emissions almost three times the 2001–2019 average. In this study, we investigate the influence of wildfires on atmospheric carbon monoxide (CO) variability through a comparative analysis of observations from the ...

ACM Computing Surveys, 2018 Modeling and simulation techniques are today extensively used both in industry and science. Parts of larger systems are, however, typically modeled and simulated by different techniques, tools, and algorithms. In addition, experts from different disciplines use various modeling and simulation techniques.

ChemSusChem, Volume 17, Issue 20, October 21, 2024.The effect of the pressure (P) and current density (j) on the performances of the pressurized CO2 electrochemical conversion in 0.1 M KHCO3 was explored using Ag cathode. A plot Faradaic efficiency vs P with a maximum was observed. Both the P and j strongly affect the selectivity of the process: the increase of P and the decrease of j favor the CO ...

Electrocatalytic Properties of meso‐ Perfluorinated Metallo Corroles for the Reduction of CO2
European Journal of Inorganic Chemistry, Volume 27, Issue 28, October 1, 2024.We have designed an electron deficient A2B corrole holding two −CF3 groups and a cyanobenzene in the meso positions and its cobalt complex. Our results clearly show that the catalyst when adsorbed on a carbon electrode, shows the most favourable catalytic performance for CO production, achieving an efficiency of 85 % with a current density of −1.5 mA ...

THE CO-ADSORPTION OF BENZENE AND CO ON Co(0001)
Surface Review and Letters, 2009 The co-adsorption of carbon monoxide and benzene on Co(0001) has been studied using density functional calculations. We used the ordered $(\sqrt 7 \times \sqrt 7\/)\ R19^{\circ}$ surface unit cell. A comparison of the co-adsorption with CO and benzene two-dimensional networks is also given. The electronic structure reveals that the CO orbitals interact

ChemistrySelect, Volume 9, Issue 36, September 25, 2024.Cathode active materials were separated from the Al foil at 400°C, and oxalates of Mn, Co, and Ni were obtained at a ratio of 1.5:1.0:2.5 by precipitation with oxalic acid after metal leaching with lactic acid. Abstract In this study, the cathode active material was first separated from the aluminum foil through a heat treatment at 500 °C.
