Hot bubbles of planetary nebulae with hydrogen-deficient winds I. Heat conduction in a chemically stratified plasma

, 2015
Heat conduction has been found a plausible solution to explain discrepancies between expected and measured temperatures in hot bubbles of planetary nebulae (PNe).

A Computational Workflow for Cell Line Profiling by Imaging Mass Cytometry

Cytometry Part A, EarlyView.
ABSTRACT In single‐cell spatial phenotyping biology, imaging mass cytometry (IMC) stands out as a cutting‐edge, highly multiplexed technology driving discoveries across various disease areas. In vitro profiling relies on tumor‐derived cancer cell lines, known for their diverse morphologies and phenotypes.

Grain orientation and temperature dependences of bubbles at tungsten surfaces upon helium plasma exposure

Nuclear Materials and Energy
The impact of grain orientation and surface temperature on helium bubble growth at tungsten surfaces exposed to low-pressure helium plasmas was investigated by analyzing the nanoholes formed at the surface.

Sonoluminescence: Nature's Smallest BlackBody

, 2000
The Spectrum of the light emitted by a sonoluminescing bubble is extremely well fit by the spectrum of a blackbody. Furthermore the radius of emission can be smaller than the wavelength of the light.

Origins of the Pangkaimen Au Deposit in the Northern Great Xing'an Range, China: Evidence From Geochronological, Geochemical, Fluid Inclusion, and H–O–S–Pb Isotope Data

Geological Journal, EarlyView.
The Pangkaimen Au–Ag deposits belong to the epithermal Au deposits, which are of great significance for guiding the research and development of this type of gold deposit. Metallogenic model diagram of Pangkaimen Au–Ag deposit. ABSTRACT The gold (Au) metallogenic belt in the northern Great Xing'an Range is characterised by the wide occurrence of the ...

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

X-rays and hard UV radiation From the First Galaxies: Ionization Bubbles and 21 cm Observations

, 2011
The first stars and quasars are known sources of hard ionizing radiation in the first billion years of the Universe. We examine the joint effects of X-rays and hard UV radiation from such first-light sources on the hydrogen and helium reionization of the

Distinguishing Terpene Structural Isomers With Dielectric Barrier Discharge Ionization (DBDI)‐Mass Spectrometry

Helvetica Chimica Acta, EarlyView.
DBDI enables real‐time analysis of volatile terpenes and generates atmosphere‐dependent reagent ions that produce structure‐specific spectral patterns. By tuning humidity or dopant gases, DBDI‐MS differentiates terpene isomers that appear identical by EI.

Probing Strongly Coupled Chameleons with Slow Neutrons

, 2013
We consider different methods to probe chameleons with slow neutrons. Chameleon modify the potential of bouncing neutrons over a flat mirror in the terrestrial gravitational field.
