Layer-by-layer (LbL) assembly is a versatile platform for applying coatings and studying the properties of promising compounds antifouling applications. Here, alginate-based LbL were fabricated by alternating deposition alginic acid chitosan or polyethylenimine to form multilayer coatings. Films prepared with either odd even bilayer numbers investigate if termination affects physicochemical pro...

Both the binder and solid–electrolyte interface play an important role in improving cycling stability of electrodes for Na-ion batteries. In this study, a novel tetrabutylammonium (TBA) alginate is used to prepare Na0.67MnO2 electrode sodium-ion batteries with improved electrochemical performance. The ageing characterized. TBA alginate-based are compared polyvinylidene fluoride- (PVDF) Na show ...

Hyaluronic acid (HA) has a number of potential biomedical applications in drug delivery and tissue engineering. For these applications, a prerequisite is to understand the characteristic of HA films directly immobilized to solid substrates. Here, we demonstrate that high molecular weight HA can be directly immobilized onto hydrophilic substrates without any chemical manipulation, allowing for t...

Several species of bacteria are known to utilize galacturonic and glucuronic acids (Thofern and Hollmann, 1956; Payne and Carlson, 1957; and McRorie, Williams, and Payne, 1959), but there have been no reports of utilization of mannuronic acid. DeLey (1953) and Starr, DeLey, and Kilgore (1957) observed that Aerobacter cloacae and Erwinia carotovora did not metabolize this acid. We have found (Pa...

Silicon was found to be a constituent of certain glycosaminoglycans and polyuronides, where it occurs firmly bound to the polysaccharide matrix. 330-554 ppm of bound Si were detected in purified hyaluronic acid from umbilical cord, chondroitin 4-sulfate, dermatan sulfate, and heparan sulfate. These amounts correspond to 1 atom of Si per 50,000-85,000 molecular weight or 130-280 repeating units....

It is desired to understand the effect of alginic acid sodium salt from brown algae (alginate) as a viscosity modifier on the behavior of blood in vitro using a micro-particle image velocimetry (µPIV) system. The effect of alginate on the shape of the velocity profile, the flow rate and the maximum velocity achieved in rectangular microchannels channels are measured. The channels were construct...
