Abstract: Soil bacterium Pseudomonas putida and green alga Raphidocelis subcapitata are often used in ecotoxicology studies, including assessment of nanomaterials. Exposure of these microorganisms to reactive nZVI, however, reduce the quality of extracted RNA for further transcriptomic analysis. [..] Read more

Abstract: This contribution is focused on utilization of a sequential chemical fractionation method for determination of organic matter content and its distribution in soil. Subsequently, this fractionation procedure was used to characterize the possible use of lignite as a soil conditioner in agriculture. [..] Read more

Abstract: Topological and edge defects and misalignment of graphene layers in few-layer graphene strongly influence its chemical reactivity and thermal stability. Scanning and transmission electron microscopy and image analysis was used to determine alignment, degree of rotation, between layers in few-layer graphene prepared by decomposition of ethanol in microwave plasma torch at atmospheric pressure.

Abstract: Nanospray transfers liquid into an aerosol via electrostatic forces created between an emitter and a counter electrode. Herein, we present compact laboratory-made instrumentation for nanospray-processing of silver colloid. [..] Read more

Abstract: PVA hydrogels can be formed via physical crosslinking (e.g. by cyclic freezing/thawing of aqueous polyvinyl alcohol solutions) or with a chemical cross-linker. [..] Read more

Abstract: The family of MAX phases and their derivative MXenes are continuously growing in terms of both crystalline and composition varieties. MXenes are a new family of two-dimensional (2D) transition metal carbides, carbonitrides and nitrides, with a general formula Mn+1AXn, where n = 1–3, M denotes a transition metal, A is an element such as aluminum or silicon, and X is either carbon or nitrogen.

Abstract: ZnO is a material that is biocompatible, biodegradable, and has low toxicity. Recently it has emerged as an interesting material for use in biomedicine, cosmetics and agriculture. [..] Read more

Abstract: Nowadays, the scientific and technological field is at a very high level, which is related, among other things, to the large production of various products, and this unfortunately brings a high degree of environmental threat. For example, highly hazardous gases might be released into the environment accidentally, therefore a solution to these dangerous situations needs to be found. [..] Read more

Abstract: Thin solid films based on organosilicon monomers are perspective in many branches of industry as well as for bioapplications. In the present study, plasma of RF capacitively coupled glow discharge in gaseous mixture of trimethylsilyl acetate (TMSA) monomer and methane was used to create SiOxCyHz coatings. [..] Read more

Abstract: We present a simple and portable setup for basic characterization of force sensors in nanoindentation instruments. The device can provide traceability to mass standards in the milli- and centinewton range. [..] Read more

Abstract: Nanocomposite polymer coatings combine attractive functionalities from the combination of organic matrix coatings and inorganic nanoparticles which allows to acquire unique properties. They can be tailored for specific needs by modifying optical, mechanical, electronic, magnetic and other properties, which may differ significantly from the properties of the bulk form.In order to study the role of the incorporated nanoparticles, topography is of fundamental importance.

Abstract: In this work, thermal stability and mechanical properties of Ti/Ni multilayer thin films were studied. The multilayer thin films were synthesised by alternately depositing Ti and Ni layers using magnetron sputtering. [..] Read more

Abstract: The hydrothermally grown ZnO micropods have been placed on grounded stainless-steel holder and exposed to an inductively coupled plasma (ICP) monitored in-situ by optical emission spectroscopy (OES). OES shows the immediate release of oxygen during Ar ion bombardment. [..] Read more

Abstract: The present study is focused on the preparation of thin films by plasma enhanced chemical vapor deposition (PEDCV) in capacitively coupled plasma (CCP). Thin films were deposited from a mixture of oxygen and hexamethyldisiloxane (HMDSO) or hexamethyldisilazane (HMDSZ). [..] Read more

Abstract: The crystallization features of nodular cast iron alloyed with 19-25% Al have been investigated. Using the Thermo-Calc computer program, polythermal sections of the phase diagrams of the quaternary Fe-Al-C-Si system were obtained on an aluminum scale from 0 to 40% with varying carbon and silicon contents between 1.5–2.5 and 1.0–2.0%, respectively. [..] Read more

Abstract: The work analyzes the influence of some pollutant elements due to metallurgical plants (defined as “metallurgical systems”) on the environment. The noise is an important pollutant factor. [..] Read more

Abstract: Top-gas dedusting at blast furnaces (BF) is usually done with venturi scrubbers. However, in recent years, the total dry dedusting of BF top-gas has become a common technology. [..] Read more

Abstract: Activation energy at hot deformation represents a valuable physical quantity which finds its application e.g. in the case of a hot flow stress description. [..] Read more

Abstract: The research examined the influence of different kinds of graphite inoculants when casting nodular cast iron on the structure and mechanical properties of the castings. The test alloy was a nodular cast iron corresponding with the ČSN EN GJS 450 standard. [..] Read more

Abstract: Three model alloys based on FeCCrNi were studied. Alloys contained 0.34  0.36 wt. [..] Read more
