Abstract: Tribological coatings are mainly used to reduce adhesive wear, which often leads to the seizure or the formation of cold welds. The low coefficient of friction and good sliding properties make it ideal for applications with low lubrication or even dry running. [..] Read more

Abstract: In this study Sm2O3/ZnO and Eu2O3/ZnO nanostructures were prepared using microwave-assisted hydrothermal method. Effect of Sm2O3 and Eu2O3 content and calcination temperature was investigated. [..] Read more

Abstract: Nanoscale zero-valent iron (NZVI) is one of the most important nanostructure for degradative remediation of environmental contaminants. In our research, NZVI was for the first time functionalized with cyclodextrins (CD), recently considered as excellent, environmentally friendly and cheap absorbents of toxic pollutants.

Abstract: Present work is dedicated to the development of lithium-nickel oxide film – positive electrode for solid-state lithium-ion batteries. The formation of electrochemical phase was performed by а two-step process. [..] Read more

Abstract: The aim of this study was to evaluate the possibility of the metallurgical wastes (slags and fly ash) utilization as a support for photocatalyticaly active composites. Metallurgical slags (MS) represent large volume group of by-products originated during the metallurgical production processes. [..] Read more

Abstract: Cellulose, as the most abundant polymer in the world, and recently nanocellulose, have emerged as sustainable, biodegradable and recyclable substrates for flexible and printed electronics in applications that require rapid roll-to-roll manufacturing. However, the wetting and printability of any material surface are linked to its surface energy. [..] Read more

Abstract: The work is focused on the assessment of mutual influence of group of spinning electrodes placed in one plane in dependence on their mutual distance, during AC-electrospinning. From the results of the experiment it was found that the distance between the electrodes affects the stability of the nanofiber production process and the siding behavior while AC-electrospinning.

Abstract: The paper deals with simulations of the distribution of electric field on the collector surface during the DC-electrospinning process. The object of the simulations was to find out whether it is possible to achieve a uniform distribution of the electric field on the surface of the circular collector. [..] Read more

Abstract: The development of micro- and nanoscale power sources for micro size electronic devices such as wireless sensors, biomedical implants, and smart cards is an important task. In this work, the processes of synthesis uniform lithium oxide, cobalt oxide, and lithium cobalt oxide thin films using atomic layer deposition (ALD) method were studied. [..] Read more

Abstract: We have developed an inexpensive and efficient technology of hydrothermal growth of ZnO nanorods from zinc nitrate hexahydrate (Zn(NO3)2·6H2O), as a precursor and hexamethylenetetramine (HMTA) (C6H12N4), as a surfactant followed by plasma hydrogenation in a novel inductively coupled plasma (ICP) quartz reactor and equipped with the rotary sample holder to stir powder during plasma treatment. We have optimized the photoluminescence spectroscopy for measuring optical scattering samples with the high sensitivity, precise sample positioning and very low influence of the scattered excitation light.

Abstract: Semiconductor-based heterogeneous photocatalysis is a promising technology for water and air purification without using consumables and generating harmful by-products. Bismuth molybdate as one of the simplestAurivillius oxides with a narrow band gap of 2.7 eV has got wide attention due to its potential for photocatalytic applications. [..] Read more

Abstract: In this work, solution-processable graphene oxide (GO) dispersions were used for the simple preparation of thin GO layers (50 nm thickness), which were reduced by low-temperature hydrogen plasma. Hydrogen plasma reduction (ideal treatment time 8 sec) led to a decrease of oxygen-containing groups and consequently, in the transformation of sp3-carbon oxidized domains to preferable sp2-carbon aromatic domains in rGO layers (XPS). [..] Read more

Abstract: Cytostatic drugs are a broad group of chemotherapy compounds mainly applied for tumor, skin diseases and infections treatments. Anticancer pharmaceutics are exhibited carcinogenic, mutagenic and teratogenic activity and have been recognized as low biodegradable so their concentration would increase in the environment. [..] Read more

Abstract: The measurements of volatile organic compounds are becoming more important due to stringent environmental regulations and increasing health concerns. The human breath which includes many volatile organic compounds that can be used as biomarkers for different diseases as well. [..] Read more

Abstract: The use of nZVI is well known method for remediation of groundwater contaminated with chlorinated hydrocarbons. The present paper investigates the ability of traditional nZVI and S-nZVI modified with sulphide ion (HS-) to reduce CHC in real wastewater sample. [..] Read more

Abstract: The photocatalytic degradation of dangerous substances is widely studied topic and many scientific reports have been already published about this issue. Undoubtedly, titanium dioxide is the most often studied compound for photocatalysis in UV region, while graphitic carbon nitride is the most often studied photocatalyst in VIS region. [..] Read more

Abstract: Precleaning of float glass is an important step in manufacturing processes based on combining its surface with other materials. Cleanness, together with surface roughness and chemical activity affect adhesion properties of the substrate that are crucial for the quality of the final product. [..] Read more

Abstract: Two powdered wastes originating in building materials production (waste brick dust (WBD) from the production of ceramic blocks and concrete slurry waste (CSW) from prestressed poles production used also in Fe-modified form (CSWFe)) were studied as potential adsorbents of ecologically risk cations (Cd2+, Pb2+) and anions (AsV as AsO43- and CrVI as CrO42-) from contaminated waters. The WBD indicated very good adsorption selectivity for Cd2+, Pb2+ and AsV at a high adsorption efficiency (>90%), and worse parameters for CrVI adsorption (<30% adsorption efficiency).
