The invention relates to a process for manufacturing a laminated material (S) comprising a fibrillated cellulose layer, characterized in that it comprises the following steps: (a) depositing a suspension (1) of fibrillated cellulose on a filtration membrane (2) and draining the suspension through that membrane so as to form a wet layer of fibrillated cellulose (A) having a dryness, that is to say a ratio between the mass of dry matter and the total mass of the fibrillated cellulose layer, of between 5% and 18%; (b) transferring the wet layer (A) under pressure to an at least partially hydrophilic surface of a substrate (B), so as to form the laminated material (S); (c) drying the laminated material. The invention also relates to a device for implementing the process.

Capture membranes for lanthanide metal ions can be made from fusion proteins having at least one lanthanide metal binding sequence (SEQ ID NO: 1-4) covalently bound to a silk-elastin-like polymer (SELP). Capture membranes can be made from silk nanofibrils that are surface-modified with a lanthanide metal binding molecule. The capture membranes can have a layered structure or can contained cross-linked peptides in a hydrogel.

Electrically conductive membranes (ECMs) have been demonstrated in the literature as a promising tool to enhance the performance of membrane-based water/wastewater treatment technologies. Membrane surface functionalization with active conductive materials is a direct and effective approach to obtain membranes with electrically conductive properties. However, a general strategy that could be utilized to fabricate ECMs using any types of commercial membrane (e.g., reverse osmosis, nanofiltration, ultrafiltration, and microfiltration) as a support or any type of conductive material as active material is not available yet. To address this need, the subject matter described herein is a facile and low-cost polyethyleneimine/glutaraldehayde-based method for synthesis of electrically conductive membranes starting from a broad range of commercial membranes (i.e., SWC4+, ESPA3, NF 270, PSf 20 KDa, and 0.1 m PVDF membranes) by using graphite or other conductive materials, including but not limited to, carbon nanotubes, activated charcoal, reduced graphene oxide, and silver nanoparticles.
