Spirals in protoplanetary disks from photon travel time [PDF]
, 2016 Spiral structures are a common feature in scattered-light images of protoplanetary disks, and of great interest as possible tracers of the presence of planets.

Advanced Functional Materials, EarlyView.It is elucidated that phase engineering of cobalt modulates the interfacial potential gradients of cobalt–carbon electrocatalysts, enhancing the intrinsic electrocatalytic performance. Modulating the dominant crystalline phase of cobalt from a hexagonal close‐packed to a face‐centered cubic enriches the electron density of carbon shells, thereby ...

Advanced Functional Materials, EarlyView.Hydrocarbon membranes are a greener alternative to PFSA in PEM fuel cells, but degrade rapidly from radical attack. We present a novel strategy using poly(vinylphosphonic acid) (PVPA) as a local radical scavenger. Incorporated as an interfacial barrier, PVPA enhances chemical stability and significantly extends membrane lifetime under accelerated ...

Toward a mathematical analysis for a model of suspension flowing down an inclined plane [PDF]
, 2017 We consider the Riemann problem of the dilute approximation equations with spatiotemporally dependent volume fractions from the full model of suspension, in which the particles settle to the solid substrate and the clear liquid film flows over the ...

Advanced Functional Materials, EarlyView.The use of continuous drop‐based force and energy probing methods is introduced to evaluate in situ chemical degradation of super liquid‐repellent surfaces by caustic liquids. By tracking the velocity of rolling drops and energy dissipation of impacting drops, degradation dynamics are resolved under high spatio‐temporal precision. Using this technique,

ANALYSIS AND STUDY OF ROLLING PARAMETERS OF COILS ON AN INCLINED PLANE
Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie ŚrodowiskaIn the article, the patterns of movement of rolls of long-fiber plant crops on an inclined plane are investigated. Experimental data on determining the rolling time of rolls on an inclined plane with angles of inclination of 25° and 10° to the horizon ...

Planet Formation In Highly Inclined Binary Systems I. Planetesimals Jump Inwards And Pile Up
, 2011 Most detected planet-bearing binaries are in wide orbits, for which a high inclination, $i_B$, between the binary orbital plane and the plane of the planetary disk around the primary is likely to be common.

Similarity solutions for unsteady shear-stress-driven flow of Newtonian and power-law fluids : slender rivulets and dry patches [PDF]
, 2012 Unsteady flow of a thin film of a Newtonian fluid or a non-Newtonian power-law fluid with power-law index N driven by a constant shear stress applied at the free surface, on a plane inclined at an angle α to the horizontal, is considered.

Advanced Functional Materials, EarlyView.A circular route, involving upcycling of waste surgical masks, affords a Mn‐based layered carbide with porosity, redox activity and low work function. These features enable its effective operation as positive supercapacitor electrode in an aqueous asymmetric supercapacitor delivering 213 Wh L−1 energy density.
