Fouling with aerobic granule membrane bioreactor

open access: yesWater Science and Technology, 2011
Aerobic granulation (AG) and membrane bioreactor (MBR) are two promising, novel environmental biotechnological processes that draw interest of researchers working in the area of biological wastewater treatment. Membrane fouling in the combined aerobic granular membrane bioreactor (AGMBR) process and the conventional MBR process was investigated in this

Porcupine‐Quill‐Inspired Shape‐Morphing Biointerfaces Disassemble Biofilms

open access: yesAdvanced Science, EarlyView.
A porcupine‐spine‐inspired dynamic offensive bio‐interface is developed for active biofilm disassembly. By coupling electrically driven nano‐dagger penetration with light‐triggered ROS generation, the surface overcomes the passive limitations of conventional mechano‐bactericidal topographies, achieving near‐complete biofilm eradication, strong ...

Correlating the hydrodynamics of fluidized granular activated carbon (GAC) with membrane-fouling mitigation

open access: yes, 2016
The mechanical scouring of membranes induced by fluidized particles is a promising method for mitigating membrane fouling. In order to further improve this technique in terms of scouring efficiency and energy requirement, the goal of the current study is

Distributions of critical flux: modelling, experimental analysis and consequences for cross-flow membrane filtration [PDF]

open access: yes, 2005
This paper discusses the distribution of critical flux (DCF) in cross flow filtration. These distributions are described here by a normal function with a mean critical flux and its standard deviation.

Synergistic Charge Scavenging in Pt/C‐Polyoxometalate Systems for Scalable Biomass Power Generation via Super‐Reduced Electrolytes

open access: yesAdvanced Science, EarlyView.
Synergistic charge scavenging between Pt/C and liquid polyoxometalate mediators effectively dismantles the inherent biological recalcitrance of raw biowaste. This dynamic interfacial electron transfer unlocks a multi‐electron super‐reduced state (>4 electrons). By overcoming traditional electron‐harvesting ceilings, this approach enables scalable, high‐

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

open access: yesAngewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

Deciphering Electrochemical Generation, Transport, and Reactivity of Hydrogen Species in the Electrochemical Palladium Membrane Reactor

open access: yesAdvanced Science, EarlyView.
This study elucidates hydrogen transport and reaction mechanisms in ePMR using 1‐hexyne hydrogenation as a model reaction. Hydrogen transport operates via dual pathways involving hydrogen atom permeation and H2‐mediated re‐dissociation on secondary metal layers.
