Thermalisation time and specific heat of neutron stars crust
, 2009 We discuss the thermalisation process of the neutron stars crust described by solving the heat transport equation with a microscopic input for the specific heat of baryonic matter.

The Crust of the Moon as Seen by GRAIL
Science, 2012 The Holy GRAIL? The gravity field of a planet provides a view of its interior and thermal history by revealing areas of different density. GRAIL, a pair of satellites that act as a highly sensitive gravimeter, began mapping the Moon's gravity in early ...

Advanced Energy Materials, EarlyView.Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...

The Diverse Modes of Oxygen Reactivity in Life & Chemistry
ChemSusChem, Volume 15, Issue 24, December 20, 2022., 2022 Breath of life: Oxygen is the quintessential molecule of life on our planet. Three molecular oxygen species dominate natural and artificial oxygenation reactions: the singlet and triplet spin states of dioxygen and ozone. This Review summarizes key applications of these molecular oxygen species in biology, medicine, technologies, and laboratories ...

Soil crusting in Western Samoa. Part II - Experimental investigation of factors influencing crust formation [PDF]
, 1971 The Alafua Penetrometer was used to measure relative differences in soil crust strength. Crust strength and thickness were shown to increase with increases in rainfall amount, drying time, droplet size, kinetic energy and soil clay and silt content.

Advanced Energy Materials, EarlyView.Structural evolution of magnetron‐sputtered Ir‐Ru alloys in PEM‐WE is studied using operando WAXS and ex situ techniques. After potential application, an Ir‐Ru@IrOx core‐shell forms, with the strained IrOx shell exhibiting higher catalytic activity and stability than pure Ir. The presence of strain is crucial for the stability as demonstrated on stable

Photoexcited Transition‐Metal Catalyzed Carbon‐Halogen Bond Formation
Angewandte Chemie, EarlyView.The recent surge of photoinitiated transition‐metal catalysis has provided a novel gateway to access carbo‐heteroatom bonds and molecular space that was not been previously attainable. Through the use of photoexcited species, the formation of C−X bonds has sought out new mechanistic pathways, finding alternatives to high reaction temperatures and ...

Resonant Shattering of Neutron Star Crusts [PDF]
, 2011 The resonant excitation of neutron star (NS) modes by tides is investigated as a source of short gamma-ray burst (sGRB) precursors. We find that the driving of a crust-core interface mode can lead to shattering of the NS crust, liberating ~10^46-10^47 ...
