Abstract: Electrospun nanofiber seems interesting in the filter domain area due to its highly porous structure, narrow pore size, and high specific surface area. In this work, polyamide 6 (PA6), polyvinylidene fluoride (PVDF), and polyacrylonitrile (PAN) nanofibers were prepared as hybrid membranes. [..] Read more

Abstract: Zinc sulfide (ZnS) is a well-known semiconductor with the wide band gap ~3.6 eV. Since the ZnS exhibits excellent transmission properties, high electron mobility, non-toxicity, water insolubility, and it is relatively inexpensive, it has been considered as an important photocatalyst for water and wastewater treatment.

Abstract: The increasing emphasis on human health and safety presupposes, among other things, the development of new safety technologies and aids that should protect people in high-risk occupations, such as firefighters, soldiers, paramedics, chemical plant workers or researchers themselves. One of the most common type of protective equipment is protective clothing. [..] Read more

Abstract: Titanium nitride (TiN) is largely applied as protective nanolayer of medical titanium implants due to its significant positive influence on the surface properties such as friction and corrosion resistance. During the process of its phase formation, occurrence of the point defects is probable and can potentially affect various material properties, e.g. [..] Read more

Abstract: Zinc sulfide (ZnS) nanocrystals were prepared at a large-scale via precipitation of Zn2+ ions water solution with gaseous hydrogen sulfide, H2S. The effect of annealing time on the ZnS phase structure, morphology, and optical properties was investigated in detail by XRD, SEM, UV-vis, and photoluminescence (PL) spectroscopy. [..] Read more

Abstract: In this work substrates able to efficiently perform so-called photo-electrochemical process are proposed. The hybrid substrates consist of a plasmon-active gold structure and a certain number of TiO2 layers deposited by the atomic layer deposition (ALD) method. [..] Read more

Abstract: The ever-increasing population has aroused demand for contraceptive chemicals which pollute the water reservoirs through industrial effluents. This has caused a severe threat to marine life and high concern about the availability of fresh drinkable water for people all over the world. [..] Read more

Abstract: The main goal of this work is to create a highly sensitive optical sensor based on the principle of plasmon surface resonance (SPR) for inorganic salts. The experimental concept includes the creation of optical fiber probe with anion capturing agent(ACA) through the diazonium chemistry for selective-entrapping of targeted compounds and their trace amounts detection.

Abstract: Covalent organic frameworks (COFs) are an emerging class of crystalline networks that are covalently built from organic components and featured by merits of low density, well-defined pore aperture, large surface area, inherent porosity, facilely tailored functionality, and ordered channel structure. Among other applications, COF compounds can be utilized for CO2 detection. [..] Read more

Abstract: Principles, design and pilot use of a new probe for zero-valent iron nanoparticles (nZVI) concentration measurement in a micro-borehole are described in the paper. Effect of nZVI on coil inductance is known and used for such measurement before; the presented improvements relate to smaller dimensions, configuration, and electric circuit data accuracy, so that the probe can detect nZVI in small volume of suspension in a narrow fracture.

Abstract: Thin-film transition metal oxides can be applied as transparent conductive coatings, photocatalysts, thermoelectric generators, and battery electrodes. In power sources application binary transition metal oxides are attractive due to high theoretical capacities. [..] Read more

Abstract: Thin-film solid-state lithium-ion batteries can provide autonomous operation of miniature devices (biosensors, smartwatches, medical devices, etc.). In this work, we investigated the processes of obtaining thin films of manganese oxide by atomic layer deposition (ALD), and their electrochemical activity as an anode of a lithium-ion battery (LIBs).

Abstract: In this work, TiO2 electron transport layers (ETL) of printed perovskite solar cells with back carbon electrode (C-PSCs) were prepared on uncleaned, chemically cleaned, and plasma-treated FTO substrates. The effect of cleaning procedure type on the quality of TiO2 ETL has been characterised by XPS and SEM. [..] Read more

Abstract: Flexible ultra-thin glass is used as a substrate or packaging material in microelectronics engineering, where the level of cleanliness determines the quality of the final product. Surface properties of glass are governed by a surface nano-layer. [..] Read more

Abstract: Energy density is one of the essential characteristics of thin-film power sources which provides the duration of the autonomous performance of sensors, energy harvesters, IoT devices, etc. The Atomic layer deposition (ALD) allows the growth of conformal coatings with a controlled composition on high aspect ratio substrates and can be used to manufacture some components of thin-film batteries.

Abstract: In the research of the alternative vibration sensing systems, the major potential is attributed to piezoelectric materials that can generate the electrical output from the waste vibration sources of the industrial machines. Poly(vinylidene fluoride) (PVDF), mostly in the electroactive β-phase, is a great option due to its excellent piezoelectric properties and good flexibility. [..] Read more

Abstract: Nanoscale zero-valent iron (nZVI) particles represent a strong reducing agent which makes them highly promising in the process of degradation of organic compounds such as persistent chlorinated compounds (e.g. chlorinated ethylenes) as well as immobilisation of inorganic pollutants (e.g. hazardous elements).
