Supported liquid membranes (SLMs) have demonstrated all along the years every high selectivity in facilitated transport of metal ions, however, they have some well known limitations, such as the gradual loss of the organic ...

Production of hydrogen using aluminum and aluminum alloys with aqueous alkaline solutions is studied. This process is based on aluminum corrosion, consuming only water and aluminum which are cheaper raw materials than other ...

Activated composite membranes (ACM) have been made based on a polysulfone layer over a non-woven support with a dense layer of aromatic polyamide, and deposited on the polysulfone using interfacial polymerisation by a ...

La particular estructura química de la matriz perfluorosulfónica del Nafion, con dominios hidrofílicos e hidrofóbicos segregados formando canales nanoscópicos, ha dado pie a su uso como modelo de estructura para la fabricación ...

The physical and chemical properties of metal nanoparticles (MNPs) are distinct from those of both bulk metal and isolated atoms. The main drawback of MNP is their instability and high trend for aggregation. Without ...

The particular chemical structure of Nafion with nanostructured and segregated hydrophilic and hydrophobic domains enables its use as a model structure for the manufacture of polymer–Metal nanocomposites. Among such ...

Chicken feathers (CFs) are a waste material generated from poultry industry in large quantities. A composite material constituted of poly lactide and CFs is proposed in order to prepare a biodegradable composite with low ...

New hybrid membranes for metal ion transport were synthesized with the aim of improving mechanical and chemical stabilities, mean lifetime and loss of carrier. Hybrid organic–inorganic materials present several advantages ...

Metal nanoparticles (MNPs) have unique physico-chemical properties advantageous for catalytic applications which differ from bulk material. However, the main drawback of MNPs is their insufficient stability due to a high ...
