- ItemA poly(3-hydroxybutyrate)-chitosan polymer conjugate for the synthesis of safer gold nanoparticles and their applications(Royal Society of Chemistry, 2018) Silvestri Daniele; Waclawek Stanislaw Witold; Sobel Bartłomiej; Torres Mendieta Rafael Omar; Novotný Vít; Nguyen Nhung Anh Huynh; Ševců Alena; Vellora Thekkae Padil Vinod; Müllerová Jana; Stuchlík Martin; Petrangeli Papini Marco; Černík Miroslav; Varma RajendraA facile and eco-friendly approach is developed for the synthesis of a poly(3-hydroxybutyrate)–chitosan (PHB–chit) polymer conjugate, which is an ideal material for the synthesis of safer gold nanoparticles (nAu). The synthesized products are characterized by various electron-based, optical and spectroscopic techniques including the catalytic activity and the stability/toxicity of nAu. In contrast to the conventional synthesis approaches, the use of PHB–chit results in generation of a highly stable and size-controlled nAu material that exhibits important catalytic activity towards the reduction of 4-nitrophenol (4-NP) to 4-aminophenol, and at the same time shows no toxicity against living bacterial systems such as Escherichia coli or Staphylococcus aureus. The synthesis route reported herein would inspire future developments that circumvent toxicity issues of relevance to living systems while performing common catalytic experimentation.

- ItemActivation process of air stable nanoscale zero-valent iron particles(ELSEVIER SCIENCE SA, 2017) Černík Miroslav; Ribas David; Benito Jóse; Filip Jan; Marti VicensNanoscale Zero Valent Iron (nZVI) represents a promising material for subsurface water remediation technology. However, dry, bare nZVI particles are highly reactive, being pyrophoric when they are in contact with air. The current trends of nZVI manufacturing lead to the surface passivation of dry nZVI particles with a thin oxide layer, which entails a decrease in their reactivity. In this work an activation procedure to recover the reactivity of air-stable nZVI particles is presented. The method consists of exposing nZVI to water for 36 h just before the reaction with the pollutants. To assess the increase in nZVI reactivity based on the activation procedure, three types of nZVI particles with different oxide shell thicknesses have been tested for Cr(VI) removal. The two types of air-stable nZVI particles with an oxide shell thickness of around 3.4 and 6.5 nm increased their reactivity by a factor of 4.7 and 3.4 after activation, respectively. However, the pyrophoric nZVI particles displayed no significant improvement in reactivity. The improvement in reactivity is related mainly to the degradation of the oxide shell, which enhances electron transfer and leads secondarily to an increase in the specific surface area of the nZVI after the activation process. In order to validate the activation process, additional tests with selected chlorinated compounds demonstrated an increase in the degradation rate by activated nZVI particles.
