Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

open access: yesArchaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Progress in Fast and Red Plastic Scintillators

open access: yesChemosensors, 2022
Radiological detection where Cherenkov residual background can be prominent requires scintillators with increased emission wavelength. Cherenkov residual background precludes the use of UV-emitting sensors such as plastic scintillators.

Study on the Characteristics of a Scintillator for Beta-ray Detection using Epoxy Resin

open access: yesEPJ Web of Conferences, 2017
A thin plate of a plastic scintillator for detecting a beta-ray was developed. The plastic scintillator was made using epoxy resin and organic scintillators such as 2.5-diphenyloxazole (PPO) and 1,4-bis [5-phenyl-2-oxazole] benzene (POPOP).

Optimization for energy response characteristics of plastic scintillators based on genetic algorithm

open access: yesAIP Advances, 2022
To address the problem that the energy response of the plastic scintillator detector is very low in the low energy range, this paper proposes a method to optimize the energy response characteristics by combining the CaWO4 energy compensation layer and ...
