this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....

Several studies have been performed to understand the influence of titanium dioxide nanoparticles (TiO2-NPs) on cell function; however the effects of nanoparticle exposure on the plasma membrane have not been addressed so far. Since this interaction may alter cell metabolism and integrity, it is of importance to understand the modifications of the cell membrane, in particular of epithelial cell...

Malaria parasites conceal themselves within host erythrocytes and establish a necessary logistics system through the three-membrane layered structures of these cells. To this system, lipid metabolism is needed for de novo synthesis lipids recycling extracellular erythrocyte components. Cholesterol supply depends on its uptake from environment cytoplasm, but phospholipids can be synthesized thei...

Microalgae have attracted great interest for biofuel production, wastewater treatment, and CO2 capture from dilute sources, but its broad implementation is limited by the high energy consumption of algae dewatering. Membrane technology has emerged as a key process dewatering, performance restrained fouling organic matter in solutions, resulting low water permeance. This review presents state-of...

Parasitization by malaria-inducing Plasmodium falciparum leads to structural, biochemical, and mechanical modifications to the host red blood cells (RBCs). To study these modifications, we investigate two intrinsic indicators: the refractive index and membrane fluctuations in P. falciparum-invaded human RBCs (Pf-RBCs). We report experimental connections between these intrinsic indicators and pa...

We have studied a number of contemporary and novel membrane probes, selected for their structural similarity to membrane raft components, in order to properly anchor themselves within a sphingolipid/cholesterol rich region. A QM/MM approach was adopted in order to understand the structural and electrostatic influences of fluorescence emission shifts of the probes in different lipid and solvatio...
