Ultrafiltration (UF) polyethersulfone (PES) membranes were prepared by wet phase inversion method. Commercial halloysite nanotubes (HNTs) in the amount of 0.5-4 wt % vs PES (15 %) introduced into casting solution containing polymer and N,N-dimethylformamide as a solvent. The morphology, physicochemical properties performance characterized scanning electron microscopy (SEM) atomic force (AFM), zeta potential, porosity contact angle analyses, well permeability measurements. Moreover,...
Series of AgNPs/TiO2-loaded carbon fiber cloth (CFC) composites were prepared by incorporation pristine TiO2 and three AgNPs-modified additives onto the surface four commercial CFCs. AgNPs/TiO2 photocatalysts synthesized wet impregnation method, including NaBH4 reduction silver ions. The content in modified photocatalyst was assessed inductively coupled plasma optical emission spectrometry (ICP‐OES) as well XRD analysis. It can be indicated that successfully reduced to Ag nanoparticles what...
Nanoporous carbons loaded with both MgO and CaO were prepared by a simple heating of mixtures consisting poly(ethylene terephthalate) natural dolomite. Preparations carried out at temperatures ranging from 850 to 1,000 °C that ensured complete thermal decomposition the dolomite contained in oxides. An influence PET/dolomite weight ratio temperature preparation process on porosity obtained composite products crystallite sizes are discussed using results nitrogen adsorption/desorption 77 K...
Porous carbons loaded with CaO and MgO were prepared through a one-step process from mixtures of poly(ethylene terephthalate) dolomite mineral. Obtained hybrid materials examined as sorbents for CO2 gas contained in air. The influence pore structure, loadings the oxides, moisture, temperature on efficiency removal is presented discussed. Performance during capture was confirmed to be influenced by all mentioned factors. As rule, increased along loading oxides. uptake also moisture content...
We performed simultaneous, multispectral CRDS measurements that for the first time use Supercontinuum light source. called this approach Cavity Ring-Down Spectrography (SC CRDSpectrography) and successfully applied it to measuring absorption spectrum of NO2 gas at a concentration 2 ppm. The extrapolated sensitivity our setup was much greater, about 5 ppb. ppb level is comparable obtainable with single wavelength dye-lasers based systems. It is, therefore, feasible construct extremely...
Abstract BACKGROUND One of the main drawbacks membrane processes is (bio)fouling. Recent attempts to overcome these phenomena focus on incorporation nanoparticles into polymeric matrices. This paper presents an investigation influence modification polyethersulfone (PES) ultrafiltration membranes with Ag/titanate nanotubes (Ag/TNTs) physicochemical characteristics, water permeability and antifouling antibacterial properties. RESULTS The modified were prepared via a wet phase inversion method...
In this study, a series of TiO2/rGO photocatalysts were obtained with two-step procedure: solvothermal method and calcination at 300–900 °C in an argon atmosphere. It was noted that the presence rGO had important role changes crystallite size specific surface area. samples, different functional groups, such as C−Cgraph, C−Caliph, C−OH, C=O, CO(O), found. observed modification suppressed anatase-to-rutile phase transformation. The photocatalytic activity nanomaterials investigated through...
The article is dedicated to measuring the thickness of step height standards using author’s version variable wavelength interferometer (VAWI) in reflected-light mode, where interference pattern created by combination two Wollaston prisms. element novelty consists replacing traditional search for coincidence fringes object and background with a continuous measurement their periods phases relative zero-order fringe. resulting system sinusoids then analyzed methods: classical one second...
Abstract The conducted studies were focused on the development of gypsum material exhibiting self-cleaning properties. To this end, raw was mixed with unique TiO 2 -based photocatalysts, previously modified by nitrogen and/ or carbon doping. photocatalytic activity obtained plasters evaluated trough degradation model organic compound (Reactive Red 198) under UV-vis irradiation. impact photocatalysts presence physicochemical properties evaluated. Furthermore, role non-metals determined. It...
The new glass as well Co2+:MgAl2O4 saturable absorber synthesis, especially developed for thermal bonding, was described. procedure of bonding presented. Generation parameters continuous wave operation at 1.5 µm wavelength were shown. threshold below 180 mW and slop efficiency over 10 % reached. Pulse generation in thermally bonded unbonded monolithic Er3+, Yb3+:glass/Co2+:MgAl2O4 microchip lasers compered. peak power above kW with pulse energy 32 µJ width 3.2 ns achieved.
The possibility of promoting the self-cleaning properties cement materials was verified by implementing obtained nitrogen and carbon co-modified titania-based (TiO2/N,C) photocatalysts into plates. Additionally, unmodified TiO2 (Grupa Azoty Zakłady Chemiczne POLICE S.A., Poland) a commercial photocatalyst P25 (Evonik Industries AG, Germany) were used as reference materials. impact treatment temperature on physicochemical TiO2/N,C additives discussed. photocatalytic activity prepared plates...
