Cosmic-ray neutron transport at a forest field site: the sensitivity to various environmental conditions with focus on biomass and canopy interception [PDF]

Hydrology and Earth System Sciences, 2017
Cosmic-ray neutron intensity is inversely correlated to all hydrogen present in the upper decimeters of the subsurface and the first few hectometers of the atmosphere above the ground surface.

Chemical Composition of Hydrothermal Pyrite as an Indicator for Deciphering Ore-Forming Processes: A Case Study from the Mamuniyeh Copper Deposit, UDMA

Journal of Economic Geology
The major and trace element content in hydrothermal pyrite was analyzed, as the most abundant sulfide mineral associated with quartz veins, to reveal ore-forming processes in the Mamuniyeh deposite, central Urumieh-Dokhtar Magmatic Arc.

Epithermal Neutron Diffractometer EXCED

hamon, 2004
A new epithermal neutron diffractormeter EXCED has been in operation at KENS neutronfacility in order to investigate the materials containing highly neutron absorbing atoms suchas gadolinium, boron, cadmium, silver and so forth.The pulsed neutrons combined with Time-Of-Flight (TOF) technique demonstrated reasonable diffractions with good Q resolutions ...

Epithermal neutron instrumentation at ISIS [PDF]

Journal of Physics: Conference Series, 2014
The advent of pulsed neutron sources makes available high epithermal neutron fluxes (in the energy range between 500 meV and 100 eV). New dedicated instrumentation, such as Resonance Detectors, was developed at ISIS spallation neutron source in the last years to apply the specific properties of this kind of neutron beam to the study of condensed matter.

Biomimetic Macrophage Cell Membrane‐Based Nanoparticles for Effective Treatment of Glioblastoma Through Boron Neutron Capture Therapy Combined With Immunotherapy

Advanced Science, EarlyView.
ABSTRACT Glioblastoma multiforme (GBM) remains largely incurable due to the blood‐brain barrier (BBB) and immunosuppressive microenvironment. While boron neutron capture therapy (BNCT) selectively eradicates tumor cells via 10B(n, α)‐7Li reactions, its clinical potential in GBM is unrealized because of the suboptimal pharmacokinetics of conventional ...

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...
