Effective yttrium based coating for steel interconnects of solid oxide cells: Corrosion evaluation in steam-hydrogen atmosphere
PublicationThis work describes manufacture, analysis and test of a new well conducting corrosion-protection coating that can be applied on steel types with high chromium content. Electrolytic deposition of yttrium salts is used to form thin (<100 nm) coatings on both flat steel sheets (material: Crofer 22 APU) and its properties are proven on woven wire-meshes (materials from two different sources: SUS316 and SUS316L). The oxide scale on...

Effect of the Catalytic Center on the Electron Transfer Dynamics in Hydrogen-Evolving Ruthenium-Based Photocatalysts Investigated by Theoretical Calculations
PublicationThe light-induced relaxation pathways in the molecular photocatalyst [(tbbpy)2Ru(tpphz)PtCl2]2+ are investigated with time-dependent density functional theory calculations together with the Marcus theory of electron transfer (ET). The calculations show that metal (Ru) to ligand (tpphz) charge transfer (MLCT) triplet states are populated following an excitation in the longer wavelength range of the absorption spectrum, but that an...

Deep learning for ultra-fast and high precision screening of energy materials
PublicationSemiconductor materials for energy storage are the core and foundation of modern information society and play important roles in photovoltaic system, integrated circuit, spacecraft technology, lighting applications, and other fields. Unfortunately, due to the long experiment period and high calculation cost, the high-precision band gap (the basic characteristic parameter) of semiconductor is difficult to obtain, which hinders the...

Structural and catalytic properties of ceria layers doped with transition metals for SOFCs fueled by biogas
PublicationThe aim of this paper was to investigate an influence of the nanocrystalline Ce0.8A0.2O2-δ (A = Mn, Fe, Co, Ni, Cu) materials on the direct internal reforming of biogas in SOFC. Structural analysis of fabricated compounds has been done. An in-situ analysis of a composition of outlet gases from operating SOFC was performed using FTIR spectroscopy with simultaneous electrical tests. It was found out, that type of dopant strongly...

Peptide conjugates of lactoferricin analogues and antimicrobials—Design, chemical synthesis, evaluation of antimicrobial activity and mammalian cytotoxicity
PublicationEight new peptide conjugates composed of modified bovine lactoferricin truncated analogues (LFcinB) and oneof the three antimicrobials — ciprofloxacin (CIP), levofloxacin (LVX), and fluconazole (FLC) — were synthesized. Four different linkers were applied to connect a peptide and an antimicrobial agent. The FLC-containing peptidic conjugates were synthesized using the “click chemistry” method. This novel approach is reported here...

Influence of the addition of citric acid on the physico-chemical properties of poly(sorbitol sebacate-co- butylene sebacate)
PublicationThe article presents the results of the physicochemical properties of poly(sorbitol sebacate- co-butylene sebacate) (PSBS) obtained with 0.25; 0.5; 0.75; 1 mol of citric acid (KC). It was shown that PSBS obtained with 0.25 and 0.5 mol KC is characterized by the most optimal mechanical and thermal properties. As a result of the study, it was found that the use of sorbitol and citric acid allows obtaining ester materials with...

Molecular and chemical monitoring of growth and Ochratoxin A biosynthesis of P. verrucosum in wheat stored at different moisture conditions
PublicationDoświadczenie polegało na obserwacji wzrostu P. verrucosum na ziarnach pszenicy, składowanej w różnych warunkach (wilgotność, temperatura) oraz zdolności do produkcji Ochratoksyny A (OTA) przez tę pleśń. Wzrost mierzony był w jednostkach tworzących kolonie (cfu colony forming units). Biosynteza OTA kontrolowana była przy pomocy HPLC, a ekspresja genu otapksPV syntetazy OTA mierzona w czasie przy pomocy odwrotnej transkryptazy...

Genetic inactivation and chemical inhibition of PARP-1 lead to increased cytotoxicity to antitumor triazoloacridone C-1305
PublicationOkreśliliśmy aktywność cytotoksyczną związku C-1305 wobec komórek z obniżoną aktywnością PARP-1 w wyniku działania inhibitora tego enzymu związku NU1025. Dane wskazują, że w zależności od rodzaju inhibitora topoizomerazy II obniżenie aktywności PARP-1 przez związek NU1025 prowadzi do zwiększenia bądź obniżenia cytotoksyczności tych leków. Działanie NU1025 prowadzi również do re-aktywacji szlaku p53 w komórkach HeLa, czego jak dotąd...
