Chapter 31. Preparation of silver doped titanium dioxide nanoparticles in microemulsion system
PublicationNanocząstki TiO2 domieszkowanego srebrem przygotowano w mikroemulsji woda-AOT-cykloheksan. Zbadano wpływ zawartości srebra (od 1,5 do 8,5% mol.) na aktywność fotokatalityczą oraz właściwości bakterio- i grzybobójcze. Stwierdzono, że TiO2 modyfikowany za 6,5% mol. Ag wykazuje najwyższą aktywność w reakcji degradacji fenolu oraz najwyższą aktywność mikrobiologiczną. Aktywność mikrobiologiczną wyznaczano jako minimalne stężenie hamujące...

Characterization of TiO2 Modified with Bimetallic Ag/Au Nanoparticles Obtained in Microemulsion System
PublicationFotokatalizatory TiO2 modyfikowane nanocząstkami bimetalicznymi Ag/Au przygotowano metodą mikroemulsyjną w układzie woda/surfaktant/cykloheksan. Aktywność fotokatalityczna próbek Ag/Au-TiO2 oszacowano przez wyznaczenie stopnia degradacji fenolu pod wpływem światła VIS. Fenol został użyty jako model zanieczyszczeń, ponieważ jest substancją niebezpieczną dla środowiska. Najwyższą aktywność w zakresie światła widzialnego wykazała...

Enhancement of photocatalytic-based processes by mono- and bimetallic (CuPd) rutile loaded nanoparticles for antibiotic resistance genes and facultative pathogenic bacteria removal
PublicationThe aim of the study was the strong reduction of facultative pathogenic bacteria (FPB), and clinically relevant antibiotic resistance genes (ARGs) from secondary effluent. To evaluate the ARGs removal efficiency comparative study of individual unit processes and combined AOPs has been performed. The present work investigated: i) removal of selected ARGs, namely blaTEM, ermB, qnrS, tetM, five FPB as well as 16S rDNA and the integrase...

Monometallic nanoparticles decorated and rare earth ions doped KTaO3/K2Ta2O6 photocatalysts with enhanced pollutant decomposition and improved H2 generation
PublicationNew, monometallic nanoparticles (MNPs) decorated surface and rare earth (RE) ions doped lattice of perovskite-type (KTaO3)/pyrochlore-type (K2Ta2O6) photocatalysts were successfully prepared by facile hydrothermal incorporation of RE ions into KTaO3/K2Ta2O6 lattices followed by photodeposition of MNPs. The impact of noble metal type (MNPs = Au, Pt, Rh) and rare earth dopant type (RE = Er, Pr) on the physicochemical properties correlated...

The Synergistic Microbiological Effects of Industrial Produced Packaging Polyethylene Films Incorporated with Zinc Nanoparticles
PublicationZinc compounds in polyolefin films regulate the transmission of UV-VIS radiation, affect mechanical properties and antimicrobial activity. According to hypothesis, the use of zinc- containing masterbatches in polyethylene films (PE) with different chemical nature—hydrophilic zinc oxide (ZO) and hydrophobic zinc stearate (ZS)—can cause a synergistic effect, especially due to their antimicrobial properties. PE films obtained on an...

Preparation of Ag/Cu-doped titanium (IV) oxide nanoparticles in W/O microemulsion
PublicationNanocząstki Cu-TiO2 oraz Ag/Cu-TiO2 otrzymano w mikroemulsji W/O. Właściwości fotokatalityczne zbadano w procesie degradacji fenolu (0,21mM) w zakresie światła widzialnego. Właściwości biobójcze zbadano poprzez wyznaczenie minimalnego stężenia zahamowania wzrostu (MIC) na szczepach bakterii E. coli, St. aureus oraz grzybów S. Cerevisiae i z rodziny Candida. Dla otrzymanych fotokatalizatorów określono wpływ stężenia domieszki metali...

Practical Approach to Large-Scale Electronic Structure Calculations in Electrolyte Solutions via Continuum-Embedded Linear-Scaling Density Functional Theory
PublicationWe present the implementation of a hybrid continuum-atomistic model for including the effects of a surrounding electrolyte in large-scale density functional theory (DFT) calculations within the Order-N Electronic Total Energy Package (ONETEP) linear-scaling DFT code, which allows the simulation of large complex systems such as electrochemical interfaces. The model represents the electrolyte ions as a scalar field and the solvent...
