Wavelength-shifter coated polystyrene as an easy-to-build and low-cost plastic scintillator detector

, 2023
We studied the light yield of a pure polystyrene slide coated with wavelength-shifter molecules, coupled to a photomultiplier, using beta particles from a 90-Sr source, as a possible easy-to-build, low-cost plastic scintillator detector.

Preparation and characterization of thermal neutron sensitive lithium doped polystyrene plastic scintillators

He jishu
BackgroundLithium-doped plastic scintillators possess the dual-mode detection capability for both fast and thermal neutrons, and combine the advantages of conventional plastic scintillators such as cost-effectiveness and the ability to fabricate in large

Simulating Arctic Greening: Microbial Responses in Thawing Yedoma Permafrost

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Arctic permafrost soils and sediments store vast amounts of organic carbon. With global warming intensifying, these soils are increasingly exposed to microbial decomposition. Further, Arctic warming and longer growing seasons drive regional greening, potentially accelerating the degradation of the previously frozen organic matter through ...

Scintillator manufacture at Fermilab [PDF]

, 1998
A decade of research into plastic scintillation materials at Fermilab is reviewed. Early work with plastic optical fiber fabrication is revisited and recent experiments with large-scale commercial methods for production of bulk scintillator are discussed.

An induction heating system for in situ X‐ray diffraction imaging: design, simulation and application to dislocation dynamics in semiconductors

Journal of Synchrotron Radiation, EarlyView.
This work presents a compact induction heating system for time‐resolved in situ X‐ray diffraction imaging. The system enables contact‐free volumetric heating up to approximately 1600°C and provides flexible operation in different operating modes. Its performance is demonstrated through representative diffraction imaging experiments.We present a compact

Characteristics of Plastic Scintillators Fabricated by a Polymerization Reaction

Nuclear Engineering and Technology, 2017
Three plastic scintillators of 4.5 cm diameter and 2.5-cm length were fabricated for comparison with commercial plastic scintillators using polymerization of the styrene monomer 2.5-diphenyloxazole (PPO) and 1,4-bis benzene (POPOP).

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

Insect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...
