In general, increase concentration of blood procalcitonin (PCT) is associated with severe bacterial infection. PCT with an optimal cutoff level of 0.5 ng/mL seems to be the most helpful biochemical parameter in detecting severe infections, mainly bloodstream infection, in patients with hematological cancers. In all clinical situations, the elevated level of PCT should be carefully analyzed, always with a thorough physical examination and an appropriate microbiological assessment. Keywords: procalcitonin, cancer, infection

Abstract

The oxygen reduction reaction was investigated at 10 monolayers (MLs) of Pt electrodeposited on (Nb–Ti)2AlC substrate. Following the discussion of detailed kinetics and electrodeposition optimisation in the authors' previous paper, the focus of this research was on stability testing. Previously performed optimisation results showed the best activity shown by 10 monolayers of Pt. Catalyst characterisation was performed by scanning electron microscopy, X-ray photoelectron spectroscopy and transmission electron microscopy. SEM, EDS and XPS analysis showed that the surface was covered with a homogeneous layer of Pt. TEM analysis of a cross-section confirmed the presence of Pt layer of thickness ∼3.5 nm, corresponding to the 10 MLs of Pt. Although the mass activity for the ORR at 0.8 V vs. RHE of 37.4 A g−1 was comparable with the best one for the Pt/C benchmark, US Department of Energy Protocols revealed excellent catalyst stability – the loss of electrochemically active surface area (EASA) was found to be only 9.3%.

Abstract

Catalysts can be successfully prepared by a simple electrochemical process. Their surface composition distinguishes catalytic activity toward hydrogen and oxygen evolution reactions. In this work, uniform Co-Ni cones were synthesized using the onestep method from an electrolyte containing a crystal modifier. Electrodeposited layers were oxidized and/or reduced in the furnace at 100°C. Freshly electrodeposited coating was stored in air atmosphere for seven days. This results in an oxide layer forming on the surface of the catalyst. Changes in the surface composition, confirmed by the XPS method, strongly influenced the wettability, catalytic performance, and size of evolved hydrogen bubbles. The conical Co-Ni surface oxidized in a controlled way possesses the best catalytic activity towards hydrogen and oxygen evolution. Conversely, the spontaneously formed oxide layer decreases the catalytic performance in mentioned reactions compared with the fresh sample. The proper storage of synthesized samples is essential due to their desired catalytic applications. Proposed controlled oxidation can be an accessible way to increase nanomaterials catalytic performance.

Abstract

Melt spun Ni70Ga30, Ni70Sn30 and Ni70In30 show different oxidation behaviour following heat treatment at 900°C in air. The Ni70Ga30 ribbon develops a continuous layer of Ga2O3 oxide, which passivates the surface and prevents further oxidation of the Ni3Ga bulk phase. On the contrary, the Ni70Sn30 and Ni70In30 ribbons undergo considerable segregation and decomposition and aside from the Ni and NiO and the primary Ni3Sn and Ni3In also comprise SnO2 and In2O3 phases. Results are conformed from XRD, TEM and XPS analysis. The oxidation behaviour especially in the case of the Ni70Sn30 ribbon is promising with view for development of fine Ni particles on the Ni3Sn support. [ABSTRACT FROM AUTHOR]

Abstract

In this paper, the crystallographic, magnetic, thermomagnetic, and magnetocaloric properties of the quenched NiMn₁₋xCrxGe (x = 0.04, 0.18 and 0.25) half-Heusler alloys have been studied by x-ray diffraction, differential scanning calorimetry and magnetization measurements. An influence of partial substitution of Cr for Mn and quenching of the samples on the character of structural and magnetic phase transitions is presented. Quenching of the alloys results in the formation of two phase (orthorhombic and hexagonal) crystal structure. The magnetic properties were investigated by means of magnetization measurements over a wide temperature (5–400 K) and magnetic field (up to 60 kOe) ranges. The experimental data indicate that at quenching and with increasing Cr content the magnetic order changes from antiferromagnetic to ferromagnetic. Hardened compounds exhibit a thermal hysteresis in the vicinity of the magnetic phase transition, what is characteristic for a first-order magnetic phase transition. The magnetic phase transition temperatures are decreased as a result of quenching of the samples. The magnetic entropy changes were calculated using the field dependences of isothermal magnetization in terms of the thermodynamic Maxwell relation. The magnetic entropy changes, |ΔSMmax|, obtained for the hardened alloys with x = 0.25 have the maximum value equal to 23 J/(kg·K) near the magnetic phase transition for a field change of ΔH = 0–60 kOe. Досліджено кристалографічні, магнітні, термомагнітні та магнітокалоричні властивості загартованих half-Heusler сплавів NiMn₁₋xCrxGe (x = 0,04, 0,18 та 0,25) за допомогою рентгенівської дифракції, диференціальної скануючої калориметрії та вимірювань намагніченості. Вивчено вплив часткової заміни Cr на Mn та гартування зразків на характер структурних та магнітних фазових переходів. Гартування сплавів призводить до утворення двофазної (ромбічної й гексагональної) кристалічної структури. Магнітні властивості досліджувалися за допомогою вимірювань намагніченості в широкому діапазоні температур (5–400 К) і магнітного поля (до 60 кЕ). Експериментальні дані показують, що при гартуванні та збільшенні вмісту Cr магнітне впорядкування змінюється від антиферомагнітного до феромагнітного. Загартовані сполуки виявляють тепловий гістерезис поблизу магнітного фазового переходу, що характерно для магнітного фазового переходу першого роду. Температури магнітного фазового переходу зменшуються в результаті загартування зразків. Зміни магнітної ентропії розраховано з використанням польових залежностей ізотермічної намагніченості в термінах термодинамічного співвідношення Максвелла. Зміна магнітної ентропії, |ΔSM max|, отримана для зміцнених сплавів з x = 0,25, має максимальне значення 23 Дж/(кг·К) поблизу магнітного фазового переходу при зміні поля ΔH = 0–60 кЕ.
