Low environmental stability of ZnO nanostructures in hydrophilic systems is a crucial factor limiting their practical applications. nanomaterials need surface passivation with different water-insoluble compounds. This study describes one-step process polycrystalline films ZnS as facile method coating. A simple sulfidation reaction was carried out gas-phase H2S and it resulted formation thin layer on the surface. The not only inhibited dissolving water but additionally improved its mechanical...
Although number of stimuli-responsive drug delivery systems based on mesoporous silica nanoparticles (MSNs) have been developed, the simultaneous real-time monitoring carrier in order to guarantee proper targeting still remains as a challenge. GQDs-MSNs nanocomposite composed graphene quantum dots (GQDs) and MSNs are proposed efficient doxorubicin fluorescent imaging agent, allowing monitor intracellular localization diffusion route from carrier. Graphene (average diameter 3.65 ± 0.81 nm)...
The aim of the study is to assess effect multi-walled carbon nanotubes (MWCNTs) on wear behavior MWCNT-doped epoxy resin. In this study, a laminating resin system designed meet standards for motor planes was modified with MWCNTs at mass fractions from 0.0 wt.% 2.0 wt.%. properties were determined in Raman spectroscopy and HR-TEM. An examination conducted linear abraser visual inspection an optical microscope SEM imaging, loss measurement, evaluation volume profilometer. Moreover, mechanical...
Composites of commercial graphene and polymer-derived nanoporous carbons were activated with KOH CO2 to increase the porosity. The materials are characterized using adsorption nitrogen, SEM/EDX, potentiometric titration. Their electrochemical performance was measured in two three electrode cells H2SO4 as an electrolyte. Activation results a significant capacitance owing development porosity surface oxygen content. To account for beneficial effect volume pores smaller than 0.7 nm on double...
Abstract The modern food industry requires new analytical methods for high-demand supplements, personalized diets, or bioactive foods development. One of the main goals is to discover ways fortification. This applies products supplements human and animal diets. In our research, we focused on solid particles AproTHEM (dried porcine hemoglobin), which approved feeding as a meat product additive, AproFER 1000 (heme iron polypeptides), still being investigated. study showed possible application...
The article discusses the release process of doxorubicin hydrochloride (DOX) from multi-wall carbon nanotubes (MWCNTs). studies described a probable mechanism and actions between surface functionalized MWCNTs anticancer drugs. (CNTs) has been modified via treatment in nitric acid to optimize adsorption process. modification efficiency physicochemical properties MWCNTs+DOX system were analyzed by using SEM, TEM, EDS, FTIR, Raman Spectroscopy UV-Vis methods. Based on computer simulations at pH...
The capability of a phthalocyanine-based voltammetric electronic tongue to analyze strong alcoholic beverages has been evaluated and compared with the performance spectroscopic techniques coupled chemometrics. Nalewka Polish liqueurs prepared from five apple varieties have used as model liqueurs. Principal Component Analysis demonstrated that best discrimination between different is achieved using e-tongue UV-Vis spectroscopy. Raman spectra chemometrics not efficient in discriminating...
Abstract It is already known that cells respond strongly to topography and chemistry of 2D surfaces. In this work we study cell–material interactions; in particular, investigated the attachment alignment SH‐SY5Y neuronal origin on grooved‐patterns made from Silicon (Si) Gold (Au). The Au–Si groove‐pattern stimulated 93% differentiate into neuroblast‐like type (N‐type) 2 days outgrown neurites exhibited strong anisotropy along grooves with 90% having one or two neurites. comparison, random...
Composite coatings provide a promising way of in vitro cell behavior screening. Previous efforts included fabrication single-walled carbon nanotubes (SWCNTs)-polymer materials, however this work, for the first time we combined two polymers different hydrophobic character: poly(maleic-alt-1-octadecene) and polyvinylpyrrolidone with multi-walled (MWCNTs) to produce composite varied hydrophobicity. Prior their incorporation, MWCNTs were characterized using Raman spectroscopy during ball-milling...
Currently, the technology of imparting necessary reflective properties to a surface is becoming increasingly important. Darkening and matting it helps diffuse reflected beam prevent glare. The surface’s are determined by its microstructure. Modern pico- femtosecond lasers make possible obtain surfaces with high precision create various LIPSS (laser-induced periodic structure) types. In this article, we describe process formation complex two-periodic microstructure on AISI 321 stainless steel...
