Concentration of ¹⁴C in liquid scintillator

, 2016
The main background hindering low-energy (≲ 200 keV) neutrino measurements with liquid scintillators comes from the minute remanence of the cosmogenic ¹⁴C (T₁/₂ ≃ 5700 a) present in the organic oil constituting the bulk of the scintillator.

High‐flux, moderate‐bandwidth, high‐energy X‐rays from lapped Si(111) crystals in a double‐crystal monochromator

Journal of Synchrotron Radiation, EarlyView.
Lapped Si(111) crystals in a double‐crystal monochromator provide high‐flux, spectrally pure, and moderate‐bandwidth X‐ray beams at 100 keV, offering a robust and cost‐effective alternative to perfect‐crystal and multilayer optics.Lapping the surfaces of Si(111) crystals in a double‐crystal monochromator significantly increases the intensity of high ...

Evaluation of illicit drug contaminants in seized cannabis in Arizona and California, 2023–2024

Journal of Forensic Sciences, EarlyView.
Abstract Despite public health concerns, fentanyl, cocaine, and other illicit drug contaminants remain largely understudied in unregulated cannabis. Here, we developed an analytical method to quantify a panel of common illicit drugs in cannabis and tested the law enforcement seizures in Arizona and California in evaluation of the illicit drug ...

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

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 ...
