Numerical modeling of two-phase underexpanded reactive CO2 into sodium jets in the frame of sodium nuclear fast reactors Supercritical CO2 (s CO2) Brayton cycles have gained interest in the frame of Sodium-cooled nuclear Fast Reactors (SFRs), as an alternative to the conventional water Rankine cyc...
For DAB (3,3′-diaminobenzidine) staining, several brain sections (~300 µm apart) were washed in PBS-T and incubated for 5 min in boiling antigen retrieval buffer (1× PBS, 0.1 M sodium citrate and 0.1 M citric acid) (Fisher Scientific, Fluka). Next, sections were washed...
Other metals, such as sodium and iron, are also found in quantities up to 100 and 60 ppm, respectively, though usually much lower. A number of methods are available for segregating metals from viscous feedstocks (especially heavy oil, extra heavy oil, and tar sand bitumen). For example, ...
the hydrogenation of the pyridine ring is easier than that of the benzene ring. Second, Kbzis stimulated by sodium benzoate, the primary component of preservatives, by increasing the concentration of benzoyl-CoA; however, Kinicis induced by INH, an anti-tuberculosis drug, which promotes the gener...
The chloroform layer (after 30 min standing) was filtered over anhydrous sodium sulfate and then concentrated under vacuum until dry using a rotary evaporator (IKA, RV10, Staufen, Germany). The dried crude extract was then dissolved in chloroform:hexane (1:1, v:v) and applied to column ...
Inactivation of SARS-CoV-2 in the liquid phase: Are aqueous hydrogen peroxide and sodium percarbonate efficient decontamination agents? ACS Chem. Health Saf. 2021, 28, 260–267. [Google Scholar] [CrossRef] [PubMed] Urban, M.V.; Rath, T.; Radtke, C. Hydrogen peroxide (H2O2): A review...
Mice and rats were anesthetized with sodium pentobarbital (150 mg/kg, i.p.) and perfused via the ascending aorta with 3.75% acrolein (Polyscience, Warrington, PA) and 2% paraformaldehyde in 0.1 mol/L of phosphate buffer (pH 7.4). Human brain biopsy tissue was rapidly immersion-fixed with ...
For the precipitation of proteins from cell culture supernatants, serum-free (OptiMEM) conditioned media of the overnight cultures were used. 10 µL (1/100 of vol.) of 2% sodium deoxycholate (NaDOC) was added to 1 mL sample and was shortly vortexed. After 30 min of incubation on ice...
Apart from these derivatives involving oxygen, chlorine and sulfur, sodium hypophosphite and red phosphorus play a role in respectively nickel electroplating and flame retardant compositions. Phosphine (PH3 derived) chemistry is very minor volume-wise but has a huge field of application in such diverse...
