Description générale

Crystals of sodium chloride belong to the cubic crystal system. It is widely employed preservative for meat, vegetable and fish products. Its effect on the growth of salmonellae (mixed inoculum of Salmonella thompson, S. stanley and S. infantis) has been investigated in laboratory medium.

Application

Sodium chloride was used in the dissolution of polymers such as poly(allylamine hydrochloride), sodium poly(styrenesulfonate) and poly(acrylic acid).

Conditionnement

Hyaluronan is an essential physiological bio macromolecule with different functions. One prominent area is the synovial fluid which exhibits remarkable lubrication properties. However, the synovial fluid is a multi-component system where different macromolecules interact in a synergetic fashion. Within this

The "layer-by-layer" (LbL) technology has been widely investigated for the coating of flat substrates and capsules with polyelectrolytes. In this study, LbL polyelectrolyte coatings applied at the surface of digitally encoded microcarriers were evaluated for the quantitative, sensitive, and simultaneous

How septin architecture is remodeled from an hourglass to a double ring during cytokinesis in fungal and animal cells remains unknown. Here, we show that during the hourglass-to-double-ring transition in budding yeast, septins acquire a "zonal architecture" in which paired

Microfluidic devices fabricated via soft lithography have demonstrated compelling applications such as lab-on-a-chip diagnostics, DNA microarrays, and cell-based assays. These technologies could be further developed by directly integrating microfluidics with electronic sensors and curvilinear substrates as well as improved automation
