Evaluation of Barkhausen Noise and Magnetoacoustic Emission Signals Properties for Plastically Deformed Armco Iron
PublikacjaArtykuł prezentuje wyniki badania wpływu różnych rodzajów deformacji plastycznej na właściwości magnetoakustyczne żelaza Armco. Badane były dwie serie próbek - pierwsza składała się ze wstępnie wyżarzonych próbek, które następnie były walcowane na zimno, w skład drugiej wchodziły natomiast próbki wycięte z komercyjnie dostępnej blachy wykonanej z żelaza Armco a następnie poddane obciążeniom rozciągającym. Walcowanie na zimno prowadzi...

Mechanical Properties of Twisted Carbon Nanotube Bundles with Carbon Linkers from Molecular Dynamics Simulations
PublikacjaThe manufacturing of high-modulus, high-strength fibers is of paramount importance for real-world, high-end applications. In this respect, carbon nanotubes represent the ideal candidates for realizing such fibers. However, their remarkable mechanical performance is difficult to bring up to the macroscale, due to the low load transfer within the fiber. A strategy to increase such load transfer is the introduction of chemical linkers...

The effect of PEDOT morphology on hexavalent chromium reduction over 2D TiO2/PEDOT photocatalyst under UV–vis light
PublikacjaThe present study represents an approach to apply organic-inorganic hybrid materials for photocatalytic removal of heavy metals from the aqueous environment. The photocatalytic activity of the semiconductor modified with the conjugated polymer may depends on the conjugated polymer type, its amount and morphology. Therefore, in the present study the effect of poly (3, 4-ethylenedioxythiophene) (PEDOT) morphology on adsorption and photoreduction...

Experimental analysis of wear resistance of compacts of fine-dispersed iron powder and tungsten monocarbide nanopowder produced by impulse pressing
PublikacjaThe paper presents the results of studying the structure and wear resistance of compacts produced from fine dispersed reduced iron powder (average particle size 3–mu m) with the addition of tungsten carbide (WC) nanopowder with the average particle size of 25–30 nm. The mass fraction of tungsten carbide (wolfram carbide) in the powder composition was 5% and 10% of the total mass. Impulse pressing was conducted using the modified...

Experimental study and numerical simulation of the dynamic penetration into dry clay
PublikacjaTests of dry clay were carried out in a uniaxial stress state using the experimental setup which implements the split Hopkinson pressure bar method. Based on the results of these experiments, the compressive strength of clay was determined as an important element of S.S. Grigoryan’s model of the soil medium. In addition, the parameters of this model are determined from the results of experiments using the modified Kolsky method...

New domino reaction. One pot synthesis of 4,7-dihydroxythioaurone derivatives from benzaldehydes and 4-acetyl-2-oxo-benz[1,3]oxathiole
PublikacjaDogodna metoda syntezy pochodnych 4,7-dihydroksytioauronów poprzez rekcję typu ''one pot'' aldehydu benzoesowego z 4-acetylo-2-oxo-benz[1,3]oxatiolem i octanem piperydyny w środowisku DMSO. Strukturę związku udowodniono metodami NMR. Układ tioauronowy powstaje w wyniku trzech kolejnych reakcji: otwarcia pierścienia oksatiolonowego, utleniania powstałego ugrupowania merkaptanowego i kondensacji z aldehydem benzoesowym.

MSP for port areas – To what extent should we interfere with governance of ports’ waters? Case study of Polish seaports
PublikacjaThe EU MSP Directive imposed the requirement to develop plans for all water areas under the jurisdiction of an EU country by the end of March 2021. Poland is the only country in the Baltic Sea Region whose maritime administration has decided to elaborate detailed maritime spatial plans for port waters. The aim of the paper is to draw conclusions from the work carried out so far on the MSP for Polish port water areas. For this purpose,...

Fast dynamics in the optical storage with Langmuira-Blodgett films of a diazocrown ether molecule
PublikacjaMolekuły z resztą azobenzenu badano z punktu widzenia licznych aplikacji wykorzystujących cykle fotoizomeryzacji trans-cis-trans, wiodących do uporządkowania cząsteczek, a nawet do transportu masy w mikroskali. Ważnym ograniczeniem dla tych materiałów jest powolna dynamika procesu porządkowania, wymagającego molekularnych przekształceń. W tej pracy informujemy o filmach Langmuira-Blodgett (LB) pochodnej eteru azokoronowego (29-membered...

Magnetic switching of Kerker scattering in spherical microresonators
PublikacjaMagneto-optical materials have become a key tool in functional nanophotonics, mainly due to their ability to offer active tuning between two different operational states in subwavelength structures. In the long-wavelength limit, such states may be considered as the directional forward- and back-scattering operations, due to the interplay between magnetic and electric dipolar modes, which act as equivalent Huygens sources. In this...

Unusual behaviour of (Np,Pu)B2C
PublikacjaTwo transuranium metal boron carbides, NpB2C and PuB2C have been synthesized by argon arc melting. The crystal structures of the {Np,Pu}B2C compounds were determined from single-crystal X-ray data to be isotypic with the ThB2C-type (space group R3m, a = 0.6532(2) nm; c = 1.0769(3) nm for NpB2C and a = 0.6509(2) nm; c = 1.0818(3) nm for PuB2C; Z = 9). Physical properties have been derived from polycrystalline bulk material in the...

Topological extraordinary optical transmission
PublikacjaΤhe incumbent technology for bringing light to the nanoscale, the near-field scanning optical microscope, has notoriously small throughput efficiencies of the order of 10^4-10^5 or less. We report on a broadband, topological, unidirectionally guiding structure, not requiring adiabatic tapering and, in principle, enabling near-perfect (∼100%) optical transmission through an unstructured single arbitrarily subdiffraction slit at...
