High-Flux Ultrafiltration Membranes Combining Artificial Water Channels and Covalent Organic Frameworks

open access: yesMembranes, 2022
Artificial water channels (AWCs) have been well investigated, and the imidazole-quartet water channel is one of the representative channels. In this work, covalent organic frameworks (COFs) composite membranes were fabricated through assembling COF ...

Ordered Domain (Raft) Formation in Asymmetric Vesicles and Its Induction upon Loss of Lipid Asymmetry in Artificial and Natural Membranes

open access: yesMembranes, 2022
Lipid asymmetry, the difference in the lipid composition in the inner and outer lipid monolayers (leaflets) of a membrane, is an important feature of eukaryotic plasma membranes.

The impact of thickness of resorbable membrane of human origin on the ossification of bone defects: A pathohistologic study [PDF]

open access: yesVojnosanitetski Pregled, 2012
Background/Aim. A wide range of resorbable and nonresorbable membranes have been investigated over the last two decades. The barrier membrane protects the defect from ingrowth of soft tissue cells and allows bone progenitor cells to develop bone ...

Applying a Hydrophilic Modified Hollow Fiber Membrane to Reduce Fouling in Artificial Lungs

open access: yesSeparations, 2021
Membranes for use in high gas exchange lung applications are riddled with fouling. The goal of this research is to create a membrane that can function in an artificial lung until the actual lung becomes available for the patient.

Multi-scale membrane process optimization with high-fidelity ion transport models through machine learning [PDF]

open access: yesJournal of Membrane Science, Volume 608, 1 August 2020, 118208, 2022
Innovative membrane technologies optimally integrated into large separation process plants are essential for economical water treatment and disposal. However, the mass transport through membranes is commonly described by nonlinear differential-algebraic mechanistic models at the nano-scale, while the process and its economics range up to large-scale ...

Pattern formation, localized and running pulsation on active spherical membranes [PDF]

open access: yesSoft Matter 17, 10614 (2021), 2021
Active force generation by actin-myosin cortex coupled to the cell membrane allows the cell to deform, respond to the environment, and mediate cell motility and division. Several membrane-bound activator proteins move along it and couple to the membrane curvature. Besides, they can act as nucleating sites for the growth of filamentous actin.

The concept of an artificial tympanic membrane [PDF]

open access: yesClinical Otolaryngology, 1984
A review is given of the development of the concept of an artificial tympanic membrane. Starting with homologous tympanic membranes we compared biodegradable collagen materials (homologous and heterologous) and biodegradable synthetic materials, poly-glycolic acid, poly-lactic acid and poly-alpha-amino acids.
