TL;DR: In this article, an effective approach to attenuate random and coherent linear noise in a 3D data set from a carbonate environment is discussed, where the authors demonstrate a seismic inline section from a noisy 3D seismic cube.
Abstract: This paper discusses an effective approach to attenuate random and coherent linear noise in a 3D data set from a carbonate environment. Figure 1 illustrates a seismic inline section from a noisy 3D seismic cube. Clearly, the section in Figure 1 is corrupted by undesirable random noise and coherent noise that are linear and vertically dipping in nature

TL;DR: In this paper, a facile synthesis of polyhedral PdPt alloy NPs via coreduction of Pd(acac)2 (acac = acetylacetonate) and Pt(acAC)2 with morpholine borane in oleylamine at 90 and 180 °C was reported.
Abstract: PdPt alloy nanoparticles (NPs) are promising catalysts for various chemical reactions because of the presence of powerful catalytic components of Pt and Pd on the surface of one nanostructure. In this paper, we report a facile synthesis of polyhedral PdPt alloy NPs via coreduction of Pd(acac)2 (acac = acetylacetonate) and Pt(acac)2 with morpholine borane in oleylamine at 90 and 180 °C. In the synthesis, the molar ratio of the two metal precursors added in the reaction mixture was carried over to the final PdPt NP product, and compositions of the PdPt NPs were readily tuned from Pd88Pt12 to Pd34Pt66. These PdPt NPs show the composition-dependent catalytic activity for methanol oxidation, with NPs in 40–60 atomic % Pt exhibiting the superior activity and durability.

TL;DR: In this paper, a decene-1 was studied in the presence of the fluorous-soluble P[CH2CH2(CF2)5CF3]3 modified rhodium catalyst at 100 °C and 1.1 MPa of CO/H2 (1:1) in a 50/50 vol % toluene/C6F11CF3 solvent mixture.
Abstract: The hydroformylation of decene-1 was studied in the presence of the fluorous-soluble P[CH2CH2(CF2)5CF3]3 modified rhodium catalyst at 100 °C and 1.1 MPa of CO/H2 (1:1) in a 50/50 vol % toluene/C6F11CF3 solvent mixture, which forms a homogeneous liquid phase at and above 100 °C. P[CH2CH2(CF2)5CF3]3 was selected on the basis of a semiempirical calculation of the electronic properties of P[(CH2)x(CF2)yCF3]3 (x = 0, y = 2, 4 and x = 0−5, y = 2) and prepared by the reaction of PH3 with CH2CH(CF2)5CF3. The solution structure of HRh(CO){P[CH2CH2(CF2)5CF3]3}3 (1) in C6F11CF3 is similar to that of HRh(CO)(PPh3)3 (2) in toluene and HRh(CO){P(m-C6H4SO3Na)3}3 (3) in water. High-pressure NMR of 1 under 2.1−8.3 MPa of CO/H2 (1:1) revealed that 1 is in equilibrium with HRh(CO)2{P[CH2CH2(CF2)5CF3]3}2 (4). Kinetic studies show that the reaction is first order in both rhodium and decene-1. While the reaction is inhibited by P[CH2CH2(CF2)5CF3]3, the normal/iso (n/i) ratio of the aldehyde increases with increasing phosphine ...

TL;DR: In this paper, a thermal method for recovering normally immobile oil from a tar sand deposit is described, where two wells are operated such that heated mobilized oil and steam flow without substantially mixing.
Abstract: A thermal method is disclosed for recovering normally immobile oil from a tar sand deposit. Two wells are drilled into the deposit, one for injection of heated fluid and one for production of liquids. Thermal communication is established between the wells. The wells are operated such that heated mobilized oil and steam flow without substantially mixing. Oil drains continuously by gravity to the production well where it is recovered.
