Low-cost performance-driven modelling of compact microwave components with two-layer surrogates and gradient kriging
PublikacjaUtilization of electromagnetic (EM) simulation tools has become indispensable for reliable evaluation of microwave components. As the cost of an individual analysis may already be considerable, the computational overhead associated with EM-driven tasks that require massive simulations (e.g., optimization) may turn prohibitive. One of mitigation methods is the employment of equivalent network models. Yet, they are incapable of accounting...

Comprehensive analysis of low-temperature methods for reclaiming of ground tire rubber
PublikacjaManagement of waste tires has become an important topic for decades. The lack of an effective method to manage the materials as mentioned above leads to illegal landfills. This problematic waste can be divided into two main categories depending on the physical condition of the waste: (i) partially used tires; (ii) end-of-life tires. While the first group can be reused or retreaded, the second group requires special measures to...

Dehydration converts DsbG crystal diffraction from low to high resolution
PublikacjaDiffraction quality crystals are essential for crystallographic studies of protein structure, and the production of poorly diffracting crystals is often regarded as a dead end in the process. Here we show a dramatic improvement of poorly diffracting DsbG crystals allowing high-resolution diffraction data measurement. Before dehydration, the crystals are fragile and the diffraction pattern is streaky, extending to 10 Å resolution....

Boron-Doped Diamond/GaN Heterojunction—The Influence of the Low-Temperature Deposition
PublikacjaWe report a method of growing a boron-doped diamond film by plasma-assisted chemical vapour deposition utilizing a pre-treatment of GaN substrate to give a high density of nucleation. CVD diamond was deposited on GaN substrate grown epitaxially via the molecular-beam epitaxy process. To obtain a continuous diamond film with the presence of well-developed grains, the GaN substrates are exposed to hydrogen plasma prior to deposition....

Reactions in nanofilms of trifluoroacetic acid (CF3COOH) driven by low energy electrons
PublikacjaBadano modyfikacje chemiczne indukowane przez niskoenergetyczne elektrony (0-20eV) w cienkich warstwach skondensowanych molekuł CF3COOH. Do badań zastosowano dwie metody: desorpcję jonów w wyniku bombardowania elektronami (ESD - Electron Stimulated Desorption) oraz termiczną desorpcję jonów (TDS - Thermal Desorption Spectroscopy).

Shaping of coherence function of sources used in low-coherent measurement techniques
PublikacjaW artykule przedstawiono zależność pomiędzy charakterystyką widmową źródła i ekwiwalentną długością drogi koherencji źródła. Wyniki analizy teoretycznej i symulacji komputerowych wykazały, że użycie źródła syntezowanego wpływa na zmniejszenie wartości ekwiwalentnej długości drogi koherencji. Dodatkowo wykazano, że zmniejszenie ekwiwalentnej długości drogi koherencji można otrzymać poprzez odpowiednie kształtowanie funkcji koherencji...

High temperature corrosion of evaporator tubes in low-emission steam boilers
PublikacjaW artykule opisano zjawisko korozji wysokotemperaturowej rur ekranowych kotłów parowych niskoemisyjnych. Przeprowadzono badania rur po eksploatacji. Wykonano badania składu chemicznego zgorzelin. Stwierdzono, że główną przyczyną pocienienia rur na wyższych poziomach jest korozja siarkowa, natomiast na poziomach niższych oddziaływanie stopionych soli.

Low-dimensional bound entanglement with one-way distillable cryptographic key
PublikacjaIn this paper, we provide a class of bound entangled states that have positive distillable secure key rate. The smallest state of this kind is 4 circle times 4, which shows that peculiar security contained in bound entangled states does not need high-dimensional systems. We show that for these states a positive key rate can be obtained by one-way Devetak-Winter (DW) protocol. Subsequently, the volume of bound entangled key-distillable...

PublikacjaIn the present research the tool of broadband dielectric spectroscopy was utilized to characterize dielectric behavior of Bi6Fe2Ti3O18 (BFTO) Aurivillius-type multiferroic ceramics. Dielectric response of BFTO ceramics was studied in the frequency domain (Δν=0.1Hz – 10MHz) within the temperature range ΔT=-100°C – 200°C. The Kramers-Kronig data validation test was employed to validate the impedance data measurements and it was found...
