Abstract: rGO-CeO2 nanocomposite has been employed and significantly improved electrochemical sensors in terms of facility, sensitivity, and accuracy. Additionally, since synthesis procedures play an important role in the structure and properties of nanomaterials, it is necessary to investigate the effect of synthesis procedures to maximize the electrochemical performance of the sensor using rGO-CeO2.

Abstract: The combination of PECVD - plasma enhanced chemical vapor deposition and VE - vacuum evaporation at one vacuum chamber is in situ method how to integrate semiconductor (Ge) and metallic (Sn) nanoparticles into amorphous hydrogenated thin films and their structures on the base of a-Si:H or a-SiC:H. In this work we focus our effort to deposit a-SiC:H thin films from monomethylsilane (MMS = SiH3-CH3) diluted by hydrogen in the ratio 2/100 sccm. [..] Read more

Abstract: This study presents a novel approach for fabricating self-standing diamond films with tailorable cavities, eliminating the need for reactive ion etching (RIE). We employed selective area deposition on SiO2/Si substrates in a microwave plasma CVD system at high temperatures (1000°C). [..] Read more

Abstract: Actually, Boron Nitride nanotubes (BNNT) have received great interest as material dedicated to many applications such as electronic and thermoelectrical devices. This work is a theoretical study of the structural, electronic and thermic transport properties of pure and iron (Fe) doped Boron Nitride nanotubes (BNNT) in its hexagonal phase (h-BN).

Abstract: MAX phase materials are nano-layered, hexagonal, metal carbides, and nitrides, where M is a transition metal, A is an element of the A-group (mostly groups 13 and 14), and X is C and/or N. These phases exhibit a unique combination of properties of both metallic and ceramic materials. [..] Read more

Abstract: Fe-Ni-based nanoparticles are promising materials for the production of high-performance permanent magnets. The research explores the preparation of Fe-Ni alloys using iron-nickel oxalate precursors, which were synthesized via the coprecipitation method and subsequently reduced in a hydrogen atmosphere.

Abstract: The rutile phase of TiO2 can generally be obtained by high-temperature calcination of anatase nanoparticles. However, calcination undoubtedly leads to agglomeration and growth, hence increasing particle size. [..] Read more

Abstract: Plasma polymerization, commonly considered a type of plasma-enhanced chemical vapour deposition (PECVD), is a popular method for depositing organic thin films. However, it often produces films with limited molecular complexity due to the necessity to use relatively low molar mass precursors that can be vaporized. [..] Read more

Abstract: Textile material, which has always been perceived as a protective layer against weather conditions, nowadays plays a vital role in wearable electronics (smart textile-based devices/ electronic textiles), contributing to the areas of energy harvesting, energy storage, sensors, real-time monitoring of healthcare, personal thermal management, etc. Thus, the main aim of the presented research was to synthesise Ti3C2Tx nanosheets with proper structure, flake size and high capacitance using a top-down synthesis approach utilising a large-size MAX (Ti3AlC2) phase precursor (100 m) for further electroconductive functionalisation of cellulose fabric.

Abstract: The incorporation of electroconductive compounds onto the textiles' surfaces leads to the fabrication of flexible electronic textiles (e-textiles) for numerous application fields, i.e., sport, medical, protective, fashion, military, etc. Their long-term functionality during daily usage depends on the sufficient durability of applied electroconductive compounds against washing, which can be significantly improved by the employment of protective layers.

Abstract: While all traditional photovoltaic materials are covalent compounds with coordination number 4, currently the most progressive materials - hybrid halide perovskites - have coordination number 6 and are ionic. This can be the key to success, especially regarding surface electronic properties, which are essential for polycrystalline semiconductors. [..] Read more

Abstract: Polymer nanocomposites, reinforced with nanoparticles such as SiO2, are gaining attention due to their improved mechanical properties. However, the impact of SiO2 nanoparticle content on machining processes, particularly tool wear and surface quality, remains insufficiently explored. [..] Read more

Abstract: Allyl isothiocyanate (AITC) has been recognized for its potent antibacterial and antioxidant properties, positioning it as a promising agent for food preservation. However, its practical application in the food industry is significantly hindered by its high volatility and strong, unpleasant odor. [..] Read more

Abstract: The removal of pollutants, especially those with long half-lives, from water remains a current challenge. Commercial bentonite and waste materials - ladle furnace slags - were selected as suitable sorbents for Sr2+. [..] Read more

Abstract: Electrical and optical properties of zinc oxide, in particular the relatively wide direct band gap of ~3.3 eV predetermines ZnO as a photocatalytic material at room temperature. ZnO itself is non-toxic and the hydrothermal growth method we use to prepare its nanostructures is environmentally friendly. [..] Read more

Abstract: The surface contamination or bulk impurities in the matrix of soda-lime glass can significantly alter glass properties and via leaching influenced the alternative glass waste utilization as a partial replacement for sand or binder in concrete-based materials for sustainable construction applications. Therefore, in this work, we perform wet chemistry (different pH) treatment of the recycled glass particles obtained from the commercial source. [..] Read more
