(I): in which: n is an integer which represents the number of amide units such that the number of ester groups present in said at least one polyamide polymer ranges from 10% to 50% of the total number of all ester groups and all amide groups comprised in said at least one polyamide ...
As shown in Figure 6b, under strong alkaline conditions (pH = 13.7), the pyrolysis product of FG has two absorption peaks (272 nm, 350 nm) and F has only one absorption peak (334 nm). The significant difference between the absorption spectra of the two indicated that the glycoside bond ...
(HGXPRT) fromThermus thermophilusHB8 was covalently immobilized onto glutaraldehyde-activated MagReSyn®Amine magnetic iron oxide porous microparticles (MTtHGXPRT). In this context, two different strategies were followed: (a) an enzyme immobilization through its N-terminus residues at pH 8.5 (...
The mixture was made alkaline with 10% potassium hydroxide and filtered and then residue was further washed with aqueous-dioxane mixture. The filtrate and washings were combined and the dioxane was evaporated under reduced pressure. The aqueous layer was extracted with ethylacetate (15 mLx 2) to...
The alkaline solution was subjected to solvent extraction with an equal volume of dichloromethane (DCM). The DCM layer containing the alkaloids was collected in a beaker and concentrated using a rotary evaporator. The concentrated solution was then dried using a water bath at 40 °C until it ...
The biocompatibility of materials is of great importance for developing new biomedical applications; among the bio-nanocomposites developed for bone tissue engineering applications are those made from chitosan, silk fibroin and magnetite [3]. Chitosan is a cationic polysaccharide obtained by alkaline deacet...
The species was the second most widespread Diploneis in the material, though generally sparse specimens were found, showing a wide range of water chemistry values, including nutrients, mostly in circumneutral and slightly alkaline running waters. In Poland, it is known from several localities of ...
A mixture of N-[(S)-(-)-methylbenzyl]-4-piperidone 7 (2 mmol) and aromatic aldehydes 8 (4 mmol) in alkaline medium (30 mL NaOH (30%)) was stirred at room temperature for 30 min. The obtained solid was filtered and crystallized from methanol to give dipolarohiles 1a–e in excell...
3.6.1. Polarisation Curves in Alkaline Medium The OER and HER polarisation curves recorded in 1 M KOH solution on the electrodes modified with the free-base porphyrin are presented in Figure 16a,b. The GP1-BN electrode was the most catalytically active for both reactions, an observation indicati...
