Thermochemical processing methods such as pyrolysis are of growing interest as a means of converting biomass into fuels and commodity chemicals in a sustainable manner. Macroalgae, or seaweed, represent a novel class of feedstock for pyrolysis that, owing to...

Local Structure of Ca.

Gels (Basel, Switzerland)

Yamamoto K, Yuguchi Y, Stokke BT, Sikorski P, Bassett DC.
PMID: 30678140

The effects of varying percentage loadings of morpholine pre-treated cellulose nanofibrils (MCNF) and carboxymethylated cellulose nanofibrils (CMCNF) on the aqueous swelling, compressive modulus and viscoelastic properties of calcium-ion-crosslinked alginate hydrogels were investigated. In addition, the pore structures of hydrogels...

Proton pump inhibitor-refractory gastroesophageal reflux disease: challenges and solutions.

Clinical and experimental gastroenterology

Mermelstein J, Chait Mermelstein A, Chait MM.
PMID: 29606884
Clin Exp Gastroenterol. 2018 Mar 21;11:119-134. doi: 10.2147/CEG.S121056. eCollection 2018.

A significant percentage of patients with gastroesophageal reflux disease (GERD) will not respond to proton pump inhibitor (PPI) therapy. The causes of PPI-refractory GERD are numerous and diverse, and include adherence, persistent acid, functional disorders, nonacid reflux, and PPI...

Modification of pH Conferring Virucidal Activity on Dental Alginates.

Materials (Basel, Switzerland)

Nallamuthu N, Braden M, Oxford J, Williams D, Patel M.
PMID: 28788042
Materials (Basel). 2015 Apr 21;8(4):1966-1975. doi: 10.3390/ma8041966.

To formulate an alginate dental impression material with virucidal properties, experimental alginate dental impression materials were developed and the formulations adjusted in order to study the effect on pH profiles during setting. Commercially available materials served as a comparison....

Biotechnol Rep (Amst). 2020 Feb 20;26:e00436. doi: 10.1016/j.btre.2020.e00436. eCollection 2020 Jun.

Alginates are polysaccharides that are of interest in various industrial applications. This is due to the viscosifying properties of alginates, which depends on the weight-average molecular weight. The aim of the present study was to evaluate the changes in...

Mechanical Properties of Composite Hydrogels of Alginate and Cellulose Nanofibrils.

Polymers

Aarstad O, Heggset EB, Pedersen IS, Bjørnøy SH, Syverud K, Strand BL.
PMID: 30971055
Polymers (Basel). 2017 Aug 19;9(8). doi: 10.3390/polym9080378.

Alginate and cellulose nanofibrils (CNF) are attractive materials for tissue engineering and regenerative medicine. CNF gels are generally weaker and more brittle than alginate gels, while alginate gels are elastic and have high rupture strength. Alginate properties depend on...
