Here, the authors report results of their study on key characteristics microscale periodic Ni-Mg-Ni-Mg film structures as metal-hydride hydrogen accumulators, namely, microstructure, phase state, operation temperatures and rate sorption/desorption processes, complete reversible mass content hydrogen, enthalpy metal hydrides’ phase-formation. The has shown that hydride-formation films can be sat...

Trace metal (Cu, Zn, Pb, Mn, Fe and Cd) levels were determined in water and sediment from the Sakumo II and Muni lagoons and the Mamahuma and Gbagbla Ankonu feeder streams, which feed the Sakumo II lagoon over a 1-year period, and their occurrences compared. Some physical parameters (temperature, pH and electrical conductivity) were also investigated. The aim of the study was to establish the p...

In this work, a Mg-5Nb metal–metal composite was reinforced with nano SiC (SiCn) ceramic reinforcement of varying volume fractions, using the disintegrated melt deposition technique. The extruded Mg-5Nb-SiCn composites were characterized for their microstructure and mechanical properties. Based on the results obtained, it was observed that the volume fraction of nano-SiC reinforcement played an...

Reducing anthropogenic carbon emission is a problem that requires immediate attention. Metal-organic frameworks (MOFs) have emerged as a promising new materials platform for carbon capture, of which Mg-MOF-74 offers chemospecific affinity toward CO2 because of the open Mg sites. Here we tune the binding affinity of CO2 for M-MOF-74 by metal substitution (M = Mg, Ca, and the first transition met...

Previous studies have shown that alfalfa shoot biomass has the ability to bind a significant amount of various individual metals from aqueous solutions. Since most heavy metal-contaminated waters contain more than one heavy metal, it was necessary to determine the binding abilities of the alfalfa biomass with multi-metal solutions. Multi-metal binding capacity experiments resulted in the follow...

algae have been proven efficient biological vectors for heavy metal uptake. in order to further study their biosorption potential, two strains spirogyra sp. and spirulina sp. have been studied under different initial metal concentrations. in recent years, the biosorption processes have been studied extensively using microbial biomass as biosorbent for heavy metal ions removal. in these studies,...
