Superior membrane distillation by induction heating of 3D rGO/Nafion/Ni foam for water treatment

open access: yes, 2020
Membrane distillation (MD) is a promising green technology that can harness waste or solar heat to treat water. Since such heat sources suffer from temporal variations, a complementary, efficient means is necessary.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Removal of boron and arsenic by forward osmosis membrane: influence of membrane orientation and organic fouling

open access: yes, 2011
The potential application of forward osmosis (FO) membranes in water treatment and desalination requires an improved understanding of the factors that govern the rejection of trace contaminants.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Computational Sensitivity Analysis on a Mathematical Model of Epileptic Seizures

open access: yesBiomath, 2015
Temporal lobe epilepsy is a serious neurological disorder characterized by complex partial seizures, which are thought to originate in the hippocampus.В  Ordinary differential equation modeling has been used to describe changes in membrane potential of ...

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

The determination and origin of fibre clogging in membrane bioreactors [PDF]

open access: yes, 2011
Membrane channel clogging in membrane bioreactors (MBRs) has been largely unexplored by the research community, despite it being widely recognised as the main impediment to sustainable MBR operation by practitioners, and reflects the difficulty of ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Anaerobic membrane bioreactors for municipal wastewater treatment [PDF]

open access: yes, 2006
Anaerobic treatment has historically been considered unsuitable for the treatment of domestic wastewaters. The work presented in this thesis focuses on the incorporation of membranes into the anaerobic bioreactor to uncouple solid retention time and ...

Nonequivalence of membrane voltage and ion-gradient as driving forces for the bacterial flagellar motor at low load

open access: yes, 2007
Many bacterial species swim using. agella. The. flagellar motor couples ion. ow across the cytoplasmic membrane to rotation. Ion flow is driven by both a membrane potential (Vm) and a transmembrane concentration gradient. To investigate their relation to
