Dextran fouling of polyethersulfone ultrafiltration membranesâCauses, extent and consequences [PDF]

open access: yes, 2007
In a recent paper [Susanto, Ulbricht, J. Membr. Sci. 266 (2005) 132], we showed that dextran does foul polyethersulfone (PES) ultrafiltration (UF) membranes by contact of the solution with the membrane surface without flux through the membrane.

Brain and Liver Dual‐Targeting Oridonin Nanoparticles to Enhance Aβ Clearance for Alzheimer's Disease Therapy

open access: yesAdvanced Science, EarlyView.
We developed a nanoparticle named OAF, which simultaneously targeted to both the brain and liver via the transferrin receptor 1 (TfR1) receptor, promoting lipoprotein receptor‐related protein 1 (LRP1) expression to enhance amyloid‐beta (Aβ) clearance. In AD mice model, OAF significantly reduced Aβ deposition and cognitive impairment, while a mitigating

Application of x-ray fluorescence spectrometry in assesment of ultrafiltration membrane surface condition at water pre- treatment units of thermal power plants

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2019
The objects of the study were the Doy Chemical hollow-fiber ultrafiltration membranes which were use for preparation of make-up water for the Novocherkasskaya Regional Thermal Power Plant (RTPP).We tried out a possibility of applying the X-ray ...

About the limits of microfiltration for the purification of wastewaters [PDF]

open access: yes, 2017
In the past, microfiltration was widely used as a pretreatment step for wastewater stream purification purposes. Experiences performed during the last years shows that microfiltration fails to maintain its performances for longer period of times ...

Microglia‐Targeted Biomimetic Tetrahedral Framework Nucleic Acid Nanovesicles for Synergistic Treatment of Sepsis‐Associated Encephalopathy

open access: yesAdvanced Science, EarlyView.
Sepsis‐associated encephalopathy (SAE) lacks effective therapies. We developed ME@FDsi, a biomimetic nanodrug using a tetrahedral framework nucleic acid to deliver disulfiram and siTNFα. It crosses the blood‐brain barrier, targets M1 microglia, inhibits pyroptosis and inflammation, and scavenges ROS.

Composition and reversibility of fouling on low-pressure membranes in the filtration of coagulated water: insights into organic fractions behaviour [PDF]

open access: yes, 2016
The primary problem for the application of microfiltration (MF) and ultrafiltration (UF) membrane technology is membrane fouling. Such is the case that understanding membrane fouling has become one of the major factors driving MF and UF membrane ...

PEC‐DFM Hybrid‐Sensor Based on Nanoparticle‐Resolved Estimation for Sensitive and Reversible Glucose Monitoring

open access: yesAdvanced Science, EarlyView.
Abstract The accurate detection of glucose in wound exudate is critically important for monitoring chronic wound healing. While photoelectrochemical (PEC) sensors are widely used, they often suffer from material degradation caused by redox reactions during operation. Herein, we introduce a dark‐field microscopy (DFM) setup integrated with a PEC system,

Low fouling conditions in dead-end filtration: Evidence for a critical filtered volume and interpretation using critical osmotic pressure [PDF]

open access: yes, 2005
This paper presents experiments showing the existence of a critical filtered volume (CFV) when operating colloid dead-end filtration. The CFV is here defined as the filtered volume below which there is no irreversible (with respect to a break in the ...

G4‐Ligand‐Directed PROTACs Unveil DR1 as a Novel Ligand‐Co‐Binding G4‐Protein and Reshape G4‐Dependent Transcription

open access: yesAdvanced Science, EarlyView.
G4‐binding proteins (G4BPs) that specifically co‐bind G4s in the presence of small‐molecule ligands represent a critical but unexplored class of proteins. We introduce G4‐Ligand‐Directed PROTACs (G4L‐TACs), a chemical platform that couples G4 ligands (PDS) to E3 recruiters to selectively degrade these ligand‐co‐binding G4BPs.

Diffusion and permeation in binary solutions: Application to\ud protein ultrafiltration [PDF]

open access: yes, 2009
During the ultrafiltration of colloidal solutions the particles can form a porous medium (filter cake) or a diffuse boundary layer (concentration polarization) above the semipermeable membrane depending on the magnitude of the filtration pressure.
