Scavenging of nickel and chromium toxicity in Aulosira fertilissima by immobilization:: Effect on nitrogen assimilating enzymes
(Pontificia Universidad Católica de Valparaíso, 2004)
Immobilized microbial nanoparticles for biosorption
(2020-07-03)
Biosorption processes emerge as an economical and eco-friendly alternative technology for the removal of pollutants present in the environment. One biosorption process application is found in the immobilization of microbial ...
Enzyme Immobilization on Maghemite Nanoparticles with Improved Catalytic Activity: An Electrochemical Study for Xanthine
(Mdpi, 2020-04-01)
Generally, enzyme immobilization on nanoparticles leads to nano-conjugates presenting partially preserved, or even absent, biological properties. Notwithstanding, recent research demonstrated that the coupling to nanomaterials ...
Small angle X-ray scattering and IR spectroscopy study of metal carbonyl complexes immobilized on a silica gel surface chemically modified with piperazine
(Elsevier B.V., 1996-01-01)
The carbonyl complexes [WCl(CO)(3)(bipy) (HgCl)] (1), [Fe(CO)(4)(HgCl)(2)] (2) and W(CO)(6)] (3) were immobilized on a silica gel surface organofunctionalized with piperazine groups. The products obtained were studied by ...

Bioremediation of Heavy Metals by Cells or Metabolites Microbial Immobilized
(CRC Press - Taylor & Francis Group, 2018)
Heavy metals concentrations in the environment increases alarmingly. Heavy metals profoundly affect biological systems either positively because they are essential in low concentrations or negatively because they are toxic. ...
Immobilization and stabilization of papain on chelating sepharose: a metal chelate regenerable carrier

Effectiveness of nanoscale zero-valent iron for the immobilization of Cu and/or Ni in water and soil samples
(Nature, 2020-12)
In the last few years, the effectiveness of nanoscale zero-valent iron (nZVI) as a treatment for polluted waters and soils has been widely studied. However, little data are available on its efficacy for metal immobilization ...
