It is increasingly recognized that material surface topography able to evoke specific cellular responses, endowing materials with instructive properties were formerly reserved for growth factors. This opens the window improve upon, in a cost-effective manner, biological performance of any used human body. Unfortunately, interplay between topographies and cell behavior complex still incompletely understood. Rational approaches search bioactive surfaces will therefore omit previously...
Reverse electrodialysis (RED) is a nonpolluting sustainable technology that converts the free energy of mixing two solutions with different salinity directly into electrical energy. Although theoretical potential high, practical power output obtained limited yet due to concentration polarization phenomena and spacer shadow effects. In this work we combine calculations direct current alternating experimental stack characterization methods quantify contribution phenomena, effects resistance in...
We present a visualization of the predicted instability in ionic conduction from binary electrolyte into charge selective solid. This develops when voltage greater than critical is applied to thin layer copper sulfate flanked by anode and cation membrane. The current-voltage dependence exhibits saturation at limiting current. With further increase voltage, current increases, marking transition overlimiting conductance. mediated appearing vortical flow that increases with voltage.
The present study investigates the possibility of inducing monovalent ion permselectivity on standard cation exchange membranes, by layer-by-layer (LbL) assembly poly(ethyleneimine) (PEI)/poly(styrenesulfonate) (PSS) polyelectrolyte multilayers. Coating (PEI/PSS)N LbL multilayers CMX membrane caused only moderate variation ohmic resistance systems. Nonetheless, had a substantial influence membranes. Permselectivity comparable to that commercial monovalent-ion-permselective was obtained with...
A sacrificial templating process using lithographically printed minimal surface structures allows complex de novo geometries of delicate hydrogel materials. The scaffolds based on cellulose and chitin nanofibrils show differences in terms attachment human mesenchymal stem cells, allow their differentiation into osteogenic outcomes. approach here serves as a first example toward designer viable for biomimetic tissue engineering. As service to our authors readers, this journal provides...
Enabling the electrification of chemical industry is crucial for sector's transition toward zero emissions and a sustainable future. Approximately 2% globally used energy dedicated to fertilizer production, including urea. The electrochemical synthesis urea from nitrogen source CO2 based on renewable can contribute reaching ambitious goal production with close emissions. However, current state technology remains at low readiness level small scale. majority studies in field employ electrode...
Abstract Foam formation is a massive challenge in submerged aerated bioprocesses, e.g., beer fermentation. While the use of antifoam may easily overcome foaming at laboratory scale, it often an unattractive solution since remains future upscaling, as reduced mass transfer and extra steps product purification analytics result increased costs. Interestingly, number studies tackling this relatively low, although literature suggests range alternatives, from avoiding to means controlling or even...
Abstract This work describes the fabrication of a novel electroconductive membrane made Ti 3 C 2 T x (MXene) nanosheet coating through one‐step pressure‐assisted technique. ‐MXene is firmly attached over polyamide–imide (PAI) microfilter by employing binder composed carboxymethyl cellulose (CMC)/glutaraldehyde (GA). Through proper amount multilayer ‐MXene, electrical conductivity 174 ± 0.16 S m −1 achieved. The rejection rates reactive red 120 (RR120), black (RB), and methyl orange (MO)...
When placed on rough hydrophobic surfaces, water droplets of diameter larger than a few millimeters can easily form pearls, as they are in the Cassie-Baxter state with air pockets trapped underneath droplet. Intriguingly, natural evaporating process drive such Fakir drop into completely wetting (Wenzel) state. Our microscopic observations simultaneous side and bottom views upon transparent microstructures elucidate water-filling dynamics suggest mechanism this evaporation-triggered...
In electrodialysis desalination processes, the operating current density is limited by concentration polarization. contrast to other membrane processes such as ultrafiltration, in electrodialysis, transport above limiting possible. this work, origin of overlimiting at cation-exchange polymers investigated. We show that, under certain experimental conditions, electroconvection conductance. The theory concerning predicts a shortening plateau length membranes with increased conductive or...
