Synthesis of eosin modified TiO2 film with co-exposed {001} and {101} facets for photocatalytic degradation of para-aminobenzoic acid and solar H2 production
PublicationOwing to the increasing photosensitivity and DNA damage properties of para-aminobenzoic acid (PABA), concerns have been raised over the exposure of humans to PABA. Solar light-driven photocatalysis (SPC) provides a promising solution for the effective removal of organic pollutants especially when directed towards sulfate radical (SO4−) production. Herein, we have developed a sulfite-enhanced SPC using Eosin-Y sensitized TiO2/Ti...

Reaction of aniline with ammonium persulphate and concentrated hydrochloric acid: Experimental and DFT studies
PublicationIn this paper, the reaction of aniline with ammonium persulphate and concentrated HCl was studied. As a result of our experimental studies, 2,4,6-trichlorophenylamine was identified as the main product. This shows that a high concentration of HCl does not favour oxidative polymerisation of phenylamine, even though the ammonium persulphate/HCl system is widely used in polyaniline synthesis. On the basis of the experimental data...

Effect of sodium acetate on citric acid production from glucose by Yarrowia lipolytica
PublicationZbadano wpływ octanu sodu na produkcję kwasu cytrynowego z glukozy w hodowli wgłębnej przez nie utylizującego octanu mutanta (oct-) Yarrowia lipolytica A-101.1.31. Octan będący ko-substratem glukozy w pożywce zwiększał produktywność i plon kwasu cytrynowego w ciągu pierwszych 24 godzin procesu. Największy pozytywny wpływ na biosyntezę kwasu cytrynowego przez Y. lipolytica A-101.1.31 miał dodatek 2g/L octanu sodu (przy zbadanych...

Novel “acid tuned” deep eutectic solvents based on protonated L-proline
PublicationThe paper presents new types of deep eutectic solvents (DESs) based on L-proline protonated using three different acids (hydrochloric, sulfuric and phosphoric)and playing the role of a hydrogen bond acceptor(HBA). Glucose and xylitol were used as hydrogen bond donors (HBD). A series of deep eutectic solvents with various mole ratios were obtained for the systems L-proline: glucose and L-proline: xylitol. Density, melting point,...

In vitro biological evaluation of a novel folic acid-targeted receptor quantum dot−β−cyclodextrin carrier for C-2028 unsymmetrical bisacridine in the treatment of human lung and prostate cancers
PublicationTraditional small-molecule chemotherapeutics usually do not distinguish tumors from healthy tissues. However, nanotechnology creates nanocarriers that selectively deliver drugs to their site of action. This work is the next step in the development of the quantum dot−β−cyclodextrin−folic acid (QD−β−CD−FA) platform for targeted and selected delivery of C−2028 unsymmetrical bisacridine in cancer therapy.Herein, we report an initial...

PublicationA short series of novel ester derivatives of N3-4-methoxyfumaroyl-(S)-2,3-diaminopropanoic acid (FMDP) containing amido or keto functions have been designed and synthesized. Their antifungal activity and inhibitory properties toward fungal glucosamine-6-phosphate synthase has also been evaluated. The obtained compounds 11-13 and 15-17 demonstrated good antifunga activity against Candida albicans. Compounds 11-13 displayed also...
