Magnetic properties and magnetocaloric effect of NdMn2−xTixSi2compounds

“…where B 0 is the isothermal bulk modulus, B′ 0 is its pressure derivative , and (Table 2). If we assume that the rare earth moment does not change with Ti content, it can be derived that the substitution of Ti atoms for Mn leads to a decrease of around -4.6 µ B per Ti atom (from linear fitting), which is much faster than that expected with a simple dilution model (in which the Ti atoms do not carry magnetic moment [34] compounds.…”

The Influence of Melting on Catalysis in Propane Oxidation

“…Phase diagram of K 2 CO 3 and V 2 O 5 ; The area marked in green indicates the applied reaction temperature range in the oxidative dehydrogenation of propane while the red dashed line indicates the studied K/V ratio (K/V = 0.6); Constructed with the combined data from literature. [41][42] Structural and chemical properties are summarized in Table S1 in the Supporting Information. A total metal oxide loading of 8.4 wt % was achieved, of which 6.4 wt % was accounted for V 2 O 5 .…”

Hollow Nanospheres with Fluorous Interiors for Transport of Molecular Oxygen in Water

“…The vials were then opened to air, and the evolution of dissolved oxygen concentration was followed using an Inlab 605 immersion probe (Mettler Toledo) (Figure 4). [6][7] The addition of a small droplet of perfluorodecalin to water did not improve the O 2 transport behavior, as the SFC droplet has a small surface area and both gas uptake and release from these droplets are slow processes. Addition of the hollow nanospheres, either fluorocarbon-or hydrocarbon-lined, also did not produce any significant change in gas sorption properties.…”

“…Liquid SFCs exhibit an impressive ability to dissolve significant amounts of gases, including xenon, nitrogen, carbon dioxide, and oxygen, [1][2][3][4] and impressively have been found to dissolve and transport higher concentrations of respiratory gases than blood. [5] SFC liquids, polymers, and emulsions have found applications in catalysis of aerobic oxidations, [6][7] in oxygenation of submerged aerobic cultures, [8] as blood substitutes [3,9] and as media for liquid ventilation [3,10] and oxygenation in lung injury treatment [11] .Although the ultra-hydrophobic nature of SFCs often benefits their application, [3,[12][13] it also makes direct incorporation of fluorous compounds into water-based systems impossible. A wide range of compatibilizing agents/systems have been proposed for suspending SFCs in water, including lipids, [14] block copolymers, [7,15] and proteins [16] .…”
