Abstract: The last few years have witnessed rapid development of biological and medical applications of graphene-based materials in drug delivery, biosensing, and bioimaging. Graphene acid is a novel graphene-based material with many interesting properties, including colloidal stability and biocompatibility [1]. [..] Read more

Abstract: Copper oxide nanoparticles (CuO NPs) are used in numerous applications including antimicrobial agents, semiconductors, chemical sensors, catalysts and others. However, their high toxic potential and growing industrial production increases the concern for health and environmental risks. [..] Read more

Abstract: Montmorillonite is one of the most important groups of phyllosilicates and is an excellent sorbent. For the facilitation of the post-sorption sorbent separation from the medium (e.g.) waste water, it is convenient to use its magnetically modified form. [..] Read more

Abstract: Nanotechnologies represent new promising approach for conservation and preservation of cultural heritage. Nanomaterials (NMs) have been shown to improve efficacy, durability and quality of the restoration due to their unique properties that can be achieved and tuned by controlling particle physico-chemical characteristics.

Abstract: Among the other elements dispersed silver holds a special place because of its protective biocidal effect and specific physicochemical characteristics depending on the particle size and shape. Absorption spectra of silver hydrosols` were monitored in processes of Ag nanoparticles (Ag-NPs) formation due to reducing reaction of Ag+ ions by tannin with AgNO3 or Ag2SO4 as precursor.

Abstract: Phase transformation during hydrogen sorption was investigated in ten chosen magnesium-based hydrogen storage (HS) materials. Chemical composition of the materials consisted of Mg, as a principal hydrogen-binding element, additive X and amorphous carbon (CB), as an anti-sticking component. [..] Read more

Abstract: In recent years, nanoparticles have high importance in various areas such as biomedical, environmental or pharmaceutical applications due to their chemical and physical properties. In all these applications, maintaining control over the particle size and shape is of high significance due to their size and shape-dependent properties. [..] Read more

Abstract: Monitoring and counting of the fine particles released during the temperature rise of the resorcinol-formaldehyde polymer suitable for conversion to carbon aerogel are discussed in the poster. Carbon aerogel is produced by heat treatment under inert atmosphere. [..] Read more

Abstract: Ion track-etched membranes are porous systems obtained by etching of the latent ion tracks using a suitable etchant solution. In this work, control of the pores’ spatial profiles and dimensions in PET polymers was achieved by varying etching temperature and etching time. [..] Read more

Abstract: Synthesis of nanoparticles was possible employing a Nd:YAG pulsed laser at fundamental harmonic. The production of nanoparticles in water depends mainly on the laser parameters (pulse duration, energy, wavelength), the irradiation conditions (focal spot, repetition rate, irradiation time) and the medium where the ablation occurs (solid target, water, solution concentration).

Abstract: For many years the applications of ion track etch materials have increased considerably, like charged particles detection, molecular identification with nanopores, ion track filters, magnetic studies with nanowires and so on. Over the materials generally used as track detector, the Poly-Allyl-Diglycol Carbonate (PADC), offers many advantages, like its nearly 100% detection efficiency for charged particle, a high resistance to harsh environment, the lowest detection threshold, a high abrasion resistance and a low production costs.

Abstract: Concrete waste after further processing can be used in the form of a micronized powder in which the non-hydrated portions are reactivated. For this purpose, nanoindentation and scanning electron microscopy with X-ray spectroscopy (SEM-EDS) are combined to determine properties of the concrete sample. [..] Read more

Abstract: The influence of lower temperature on size and polydispersity of silver nanoparticles prepared by reduction of the silver(I) diamine complex cation by sodium borohydride was studied. The preparation was carried out in ethylene glycol and ethanol in the presence of stabilizing agents. [..] Read more

Abstract: Polymer-based colloid lithography represents the very effective approach for creation of a large-scale template for subsequent surface modification. Utilization of this approach, however, is significantly restricted by the ability of used micro/nanospheres to create only limited number of symmetrical structures. [..] Read more

Abstract: There are many methods that allow detection of complex analytes such as soil contaminants and explosives, which can be dispersed in the various of liquid and solid. Nevertheless, it remains a challenge to create a lab-on-a-chip (LoC) platform for on-line detection of small analytes volumes (below the few femtoliters), with high sensitivity, specificity and reliability.

Abstract: Sub-nanosecond electrical breakdown in dielectric liquids is of vital interest for applications, e.g. in high-voltage insulation, high-current switching and electric field-cell interactions. [..] Read more

Abstract: Humic substances represent a wide range of organic compounds generated by gradual decomposition of plant residues and dead organisms in our ecosystems. They are among the most widespread compounds in the world that contain a huge amount of carbon in its structure. [..] Read more

Abstract: Quantitative STEM imaging together with Monte Carlo simulations of electron scattering in solids can bring interesting results about properties of many thin samples. It is possible to determine thickness of a sample, to calculate mass of particles and measure mass per length/area. [..] Read more

Abstract: In this study, milife fabrics (polyester nonwoven fabrics) were used. Three common silanes including octyltriethoxysilane, phenyltriethoxysilane and tetraethoxysilane have been prepared by sol-gel technique to treat the milife fabrics with and without copper coating. [..] Read more

Abstract: Nano-sized materials become irreplaceable component of a number of devices for every aspect of human life. The development of new materials and deepening of the current knowledge require a set of specialized techniques – deposition methods for preparation/modification of the materials and analytical tools for proper understanding of their properties.
