Evolution of mixing state of black carbon particles: Aircraft measurements over the western Pacific in March 2004 [PDF]

, 2007
We report the evolution of the mixing state of black carbon (BC) particles in urban plumes measured by an airborne single particle soot photometer. The aircraft observations were conducted over the ocean near the coast of Japan in March 2004.

Revisiting the pre-main-sequence evolution of stars II. Consequences of planet formation on stellar surface composition

, 2018
We want to investigate how planet formation is imprinted on stellar surface composition using up-to-date stellar evolution models. We simulate the evolution of pre-main-sequence stars as a function of the efficiency of heat injection during accretion ...

Coupling Nitrogenous Organic Wastewater Treatment and Biorefinery via N‐Cycling Bacterium

Advanced Science, Volume 13, Issue 7, 3 February 2026.
The vast reservoir of nitrogenous organic pollutants in industrial wastewaters can serve as untapped carbon‐nitrogen resources. This study employs the newly discovered Paracoccus sp. ZQW‐1 as a versatile chassis to simultaneously achieve N‐methylpyrrolidone (NMP) wastewater depuration and polyhydroxybutyrate (PHB) synthesis.

Methane Planets and their Mass-Radius Relation

, 2015
Knowledge of both the mass and radius of an exoplanet allows us to estimate its mean density, and therefore its composition. Exoplanets seem to fill a very large parameter space in terms of mass and composition, and unlike the solar-system's planets ...

Type II Hot Corrosion of Two Mo‐Si‐Ti Alloys and Mo‐Si‐B With a Salt Deposit of Mixed Na2SO4 and NiSO4

Materials and Corrosion, Volume 77, Issue 2, Page 177-187, February 2026.
Schematic drawings of the hot corrosion mechanisms of (a) Mo‐9Si‐8B (at.%), (b) Mo‐21Si‐34Ti (at.%) and (c) Mo‐20Si‐52.8Ti (at.%) with a NiSO4/Na2SO4 deposit at 700°C in a SO2‐containing atmosphere. ABSTRACT To enhance turbine efficiencies by increasing gas inlet temperatures, new materials must be developed which can withstand harsh corrosive ...

Composition of Ices in Low-Mass Extrasolar Planets

, 2008
We study the formation conditions of icy planetesimals in protoplanetary disks in order to determine the composition of ices in small and cold extrasolar planets. Assuming that ices are formed from hydrates, clathrates, and pure condensates, we calculate

Orbital Variability in Grazing Proportion: New Insights From Sedimentary Amino Acid δ15N Records of the Western Equatorial Pacific

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract The carbon sequestration capacity of the biological carbon pump (BCP) is determined by surface ocean carbon fixation and the transportation of fixed carbon to the ocean interior, which is closely linked to the trophic structure of planktonic ecosystem.

A gas‐tight bonding/sealing of different bulk ceramics for robust oxygen separation at ultra‐high temperatures

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
A gas‐tight bonding/sealing of different bulk ceramics allows the operation of membrane up to the maximum temperature permitted by the membrane materials and demonstrates excellent robustness and stability in long‐term and thermal cycling tests. Abstract Oxygen transport membrane (OTM) is an economic technology for oxygen separation and high‐purity ...

High‐Entropy Alloy Design Toward Cobalt Substitution for High Hardness and Low Wear Rate Using X–Cr–Fe–Mn–Ni System

Advanced Engineering Materials, Volume 28, Issue 2, January 21, 2026.
This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...
