Few materials can match zirconium's corrosion resistance in hot, concentrated hydrochloric acid environments. However, even with zirconium's superior corrosion resistance, it can be susceptible to stress corrosion cracking (SCC) and intergranular attack (IGA) when ferric ions are present. When proper ...
THEo-nitrophenylsulphenyl (NPS) residue has recently been introduced as an amine-protecting group for amino-acids and peptides during peptide synthesis by Zervaset al.1. It is readily cleaved by mild acidolysis using 2–3 equivalents of hydrochloric acid in ether. Although this treatment allows ...
Ye and co-workers synthesized pH-responsive RTCDs using p-phenylenediamine, o-phenylenediamine, and dopamine as ingredients and hydrochloric acid as the solvent42. These RTCDs show a linear pH response in the range of 3.5–6.5, with fluorescence decreasing with increasing pH. The pH-responsive be...
Specifically, the culture pH was significantly reduced to pH 3 (utilizing a 5 M hydrochloric acid (HCl) solution) for a duration of 10 min or elevated to pH 12 (using a 5 M NaOH solution) for an equivalent 10-min interval, following an alternating pattern, as necessitated by the ...
Adsorption behavior and mechanism of pentachlorophenol on reed biochars: pH effect, pyrolysis temperature, hydrochloric acid treatment and isotherms. Ecol Eng 90:225–233. https://doi.org/10.1016/j.ecoleng.2016.01.039 Article Google Scholar Ponnusamy VK, Nagappan S, Bhosale RR, Lay C-H, Duc ...
the mixture is diluted with distilled water, pH value of the mixture is adjusted to 6.5 to 7.5 with dilute hydrochloric acid, the mixture is filtered, produced sediment is collected and is recrystallized with acetonitrile, so that the fluorescence probe N-(2-(1H-benzimidazolyl)phenyl)-2-(2-...
Moreover, etching of Ti3C2Tx can be achieved in a polar organic solvent with the assistance of NH4HF2 [29]. In addition, HF acid can be produced in-situ via the combination of fluoride salts and hydrochloric acid (HCl), which also can be used to etch MAX phases. As revealed by Ghi...
9). The chemical stability of NKCOF-10 was examined via treating with boiling water, sodium hydroxide (NaOH, 10 M), and hydrochloric acid (HCl, 12 M), respectively. The crystallinity and skeletal structures can be retained, as verified by FT-IR and PXRD (Supplementary Fig. 10). The...
Pepsin is the proteolytic enzyme of pepsinogen and is activated by hydrochloric acid, which has a hydrolytic effect on proteins. It is released solely by gastric chief cells and participate in the development of reflux-related disorders. It can be detected in saliva when gastroesophageal reflux or...
