Problem-based learning on cell biology and ecophysiology using integrated laboratory and computational activities

open access: yesMultidisciplinary Journal for Education, Social and Technological Sciences, 2016
Since all the known biological systems require water for their basic biochemical processes, one can find several osmoregulation mechanisms on living organisms for adaptation to related environmental challenges.

Adsorption and Separation by Flexible MOFs

open access: yesAdvanced Materials, EarlyView.
Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,

Remarks on osmosis, quantum mechanics, and gravity [PDF]

open access: yes, 2011
Some relations of the quantum potential to Weyl geometry are indicated with applications to the Friedmann equations for a toy quantum cosmology. Osmotic velocity and pressure are briefly discussed in terms of quantum mechanics and superfluids with connections to gravity.

Heterogeneous Nanopore Arrays – Selective Modification of Nanopores Embedded in a Membrane

open access: yesAdvanced Materials, EarlyView.
Biological processes rely on the concerted action of channels with different functionalities embedded in the same membrane. Inspired by nature, heterogeneous nanopore arrays are prepared where two nanopores are connected in parallel and function as two different elements of an ionic circuit: a diode and a resistor.

Comparison of the performance of two reverse osmosis membranes for the final purification of olive mill wastewater [PDF]

open access: yes, 2015
Two quite different reverse osmosis (RO) polymeric membranes were examined for the final purification of olive mill wastewater from two-phase olive mills (OMW2): the first one is a thin-film composite (TFC) membrane consisting of polyamide active layer ...
