Abstract: Recently discovered two-dimensional (2D) transition metal carbides and nitrides (MXenes) have received tremendous attention because of their unique electrical, optical and chemical properties. These exceptional properties make them a suitable candidate for a variety of applications including multimodal tumor therapy by photothermal effect. [..] Read more

Abstract: Bioartificial heart valves and vascular grafts prepared from decellularized tissues could be recellularized with bone marrow-derived mesenchymal stem cells (MSCs) that are able to differentiate into both smooth muscle cells and endothelial cells. MSCs differentiation is facilitated by sustained release of growth factors. [..] Read more

Abstract: Nanotechnology is a scientific field for the characterization, production, and application of nanoscale particles of 1-100 nm size. Due to their large surface area and small size, nanoparticles have different properties compared to bulk materials such as mechanical, electrical, magnetic, and chemical properties. [..] Read more

Abstract: Nanoparticles are widely used in industry as well as biomedicine. An interesting group are aluminium oxide nanaoparticles (alumina nanoparticles) belonging to the family of metal oxide nanoparticles, which can be prepared by various methods (the sol-gel, precipitation, micro-emulsion and hydrothermal methods).

Abstract: Insulin is a peptide hormone produced by beta cells of pancreatic islets. In type 1 diabetes mellitus, these islets are destroyed by the body’s own immune system, no insulin is produced and the blood glucose level is increased. [..] Read more

Abstract: The prevalence of chronic wounds is increasing due to the population ageing and specific illnesses like diabetes mellitus and vascular diseases. Nanofibrous membranes fabricated using synthetic polymers are promising materials to enhance skin wound healing. [..] Read more

Abstract: Motivated by our experimental research related to silver nanoparticles with various morphologies, we have employed quantum-mechanical calculations to provide our experiments with theoretical insight. We have computed properties of a 181-atom decahedral silver nanoparticle and two types of internal extended defects, 𝛴5(210) grain boundaries (GBs) and quadruple junctions (QJs) of these GBs.

Abstract: Nanoparticles are present in everyday life including industry, and this article focuses mainly on their occurrence in the work environment. We measured the concentration of nanoparticles in anthropogenic activity, where nanoparticles are generated as unwanted waste. [..] Read more

Abstract: For additive production, where the material is prepared by applying thin layers, a simplified designation 3D printing has been used. During this production volatile organic compounds and ultrafine particles are emitted into the air. [..] Read more

Abstract: Knowledge of behaviour of pharmaceuticals as contaminants in nature is essential for their mobility and toxicity in the soils and surface- and ground-water environments. Their migration ability and toxicity can be affected by their interactions with organic matter. [..] Read more

Abstract: Domestic boilers are generally characterized by higher emissions of airborne dust. A commonly used secondary method of reducing emissions in the energy sector is a cyclone. [..] Read more

Abstract: Metal oxide nanoparticles are increasingly being produced and will inevitably and up in the aquatic environment. In this work, we focus on the metal oxide nanoparticles CuO. [..] Read more

Abstract: Diffraction and refraction optically variable image elements are basic building blocks of planar structures for advanced security of documents and valuables. A sampler formed by an array of 36 diffraction structures - binary, tertiary, quaternary and blazed gratings (period range 400 nm - 20,000 nm) - represents a cross-section throughout technological steps - mastering, galvanic replication and embossing.

Abstract: This contribution is focused on utilization of a sequential chemical fractionation method for determination of organic matter content, its distribution in biochar and the possible use of biochar as a soil conditioner in agriculture. For these purposes the optimized chemical fractionation procedure was used to reveal the content of organic matter in different biochar samples with different properties (samples with European biochar certification for usage in agriculture) which depend significantly on the temperature used during a pyrolysis of biomass residues in the process of biochar production.

Abstract: It is already known, that porphyrin–bases are offering better protection against steel corrosion than metalloporphyrins due to their ability to form very stable metallic complexes by linking in their inner core the iron contained in different steels. In this respect, 5-(4-carboxy-phenyl)-10,15,20-tris-(4-phenoxy-phenyl)-porphyrin was synthesized by multicomponent Adler-Longo synthesis, using two different aldehydes and pyrrole, characterized to certify the structure and further used for formulating double thin layers in all possible combinations with MnTa2O6.

Abstract: Plasma hydrogenation of hydrothermally grown ZnO nanorods was done at 13.56 MHz in inductively coupled plasma (ICP) with H2/Ar gas mixture. Plasma was monitored by optical emission spectroscopy (OES) and by measuring self-bias potential of the stainless-steel sample holder isolated from the ground by a capacitor. [..] Read more

Abstract: An overwhelming majority of applications of nanofibrous webs requires sufficiently smooth character of nanofibres surface. This character is apart other parameters strongly influenced by a concentration of chosen polymeric material in the solvents. [..] Read more

Abstract: Light scattering techniques represent a group of methods providing the absolute information on the molecular weight, particle size, conformation, polydispersity and the stability of analyzed dispersion systems. These techniques are primarily used for the characterization of biopolymers, synthetic polymers and nanoparticles. [..] Read more

Abstract: In recent years the study of mechanical properties using atomic force microscopy (AFM) has become very popular. As it uses much lower forces than nanoindentation methods it allows to focus on smaller volumes which makes it an excellent tool for the study of thin films and the creation of high-resolution maps.

Abstract: Shear thickening fluid (STF) - often referred to as dilatant fluid - is a non-Newtonian suspension of a solid component in a liquid carrier, with an unique ability to dissipate the impact energy. The viscosity of STFs increases abruptly with a growing shear rate. [..] Read more
