We investigated the optical properties of colloidal-synthesized ZnO spherical nanoparticles prepared from 1-octadecene (OD), a mixture of trioctylamine (TOA) and OD (1:10), and a mixture of trioctylphosphine oxide (TOPO) and OD (1:12). It is found that the green photoluminescence (PL) of samples from the mixture of TOA/ OD and TOPO/OD is largely suppressed compared with that from pure OD. Moreo...

Platinum and ruthenium can be simultaneously extracted from hydrochloric acid solution by high molecular weight amines (trioctylamine (TOA) or diantipyrylmethane (DAM) in 1,2-dichloroethane) after preliminary conversion into the complexes with SnCl3 ligands. The determination of both metals in the presence of each other in organic solutions of the formed ion-pairs can be accomplished by applyin...

Value-added compounds were obtained from pine wood bio-oil, converting it into a renewable source for several chemicals: acids (acetic acid), sugars (levoglucosan), furan derivatives (furfural) and phenolics (catechol, phenol, 4-propylguaiacol, vanillin). To achieve this, firstly comparison of direct pyrolysis at 500 °C versus two-staged (300 °C) was made. It determined that ensue in the obtain...

In the following study, extraction of three pharmaceutical compounds: Diclofenac (DCF), ibuprofen (IBP), and carbamazepine (CBZ) by liquid-liquid their transport supported liquid membrane (SLM) using different commercial extractants (Cyanex 923 (Cy923), trioctylamine (TOA), tributylphosphate (TBP), Versatic Acid 10 (neodecanoic acid)) were evaluated. Cy923 was demonstrated to be an efficient ex...

Volatile fatty acids (VFAs) can be readily produced from many anaerobic microbes and subsequently utilized as precursors to renewable biofuels and biochemicals. Megasphaera elsdenii represents a promising host for production of VFAs, butyric acid (BA) and hexanoic acid (HA). However, due to the toxicity of these acids, product removal via an extractive fermentation system is required to achieve...
