Or should we all take a deep breath give it a second chance? That all depends on the purpose you're using it for. First, let's discover more about what borax actually is. It is another name for a naturally occurring compound mined in southern and central California called sodium ...
mixture is concentrated under reduced pressure with heating and stirring. The distillation headis replaced by a water-cooled reflux condenser, and the residue is dissolved in 1 L of 6 Msodium hydroxide and refluxed for 4 hr. The mixture is saturated with potassium carbonate(ca. 400 g); cooled...
An aqueous composition for the protection of metal surfaces against corrosion includes, as an emulsion in water at least one overbased compound which is a water-insoluble salt. The overbased compound has a basic neutralization number of more than 40. In addition to the overbased compound, the ...
Plant roots integrate environmental signals with development using exquisite spatiotemporal control. This is apparent in the deposition of suberin, an apoplastic diffusion barrier, which regulates flow of water, solutes and gases, and is environmentally
The active substance of this mixture was purified and the structure elucidated [13]. The compound is an acylphloroglucinol and was named rhodomyrtone (Rom). Rom and its isomer, rhodomyrtosone B, could be chemically synthesized; both isomers showed similarly high antimicrobial activity [14]. Rom...

Finally, the same microalgae were exposed to a medium containing a mixture of antibiotics, including macrolides, fluoroquinolones, sulfonamides, and trimethoprim, and H. pluvialis showed the highest overall removal with a median of 93 %. At the lowest concentration (20 μg·L−1), all drugs ...
Using 10 μL of the eluted fractions, the caseinolytic activity was measured from their reaction with a buffered casein solution (375 μL, 3.3 mg/mL casein, 83 mM Tris–HCl, pH 7.5)39. The mixture was incubated for 30 min at 30 °C. After the reaction was stopped by adding 125 μ...
