Experimental absorption corrections for highly absorbing europium compounds in powder neutron diffraction

Journal of Applied Crystallography, EarlyView.
An experimental method for absorption correction of powder samples containing highly neutron absorbing elements is reported.For materials with strong neutron absorption, such as europium (Eu), the absorption correction method is important but difficult to manage. This is because Eu has a strong isotope dependence. The energy dependence of absorption is

Examining the role of freebase nicotine in the harm reduction potential of oral nicotine pouches versus moist snuff: A randomized crossover trial

Addiction, EarlyView.
Abstract Background and aims Oral nicotine pouches (ONPs) contain varying proportions of freebase nicotine (FBN), with higher FBN expected to increase nicotine delivery across the oral mucosa. Because ONPs contain fewer toxicants than moist snuff and may serve as a reduced harm alternative for smokeless tobacco, we compared how the FBN in ONPs affects ...

Nicotine pouches and clinical outcomes related to smoking cessation: A systematic review of randomized trials

Addiction, EarlyView.
Abstract Background and aims Tobacco‐free nicotine pouches (NPs) are oral nicotine products promoted by manufacturers and some researchers as tools that may reduce nicotine cravings and support smoking reduction or cessation. However, evidence regarding their actual clinical impact remains limited.

Quality from Kent: Preliminary results from the analysis of fifth‐ to seventh‐century silver alloys

Archaeometry, EarlyView.
Abstract This paper explores early results from the chemical and lead isotope analysis of 30 silver‐alloy objects from southeast England dating between the fifth and seventh centuries CE, presenting limited aspects of the three main analyses that were conducted. First, a comparison of the results gained from surface x‐ray fluorescence (pXRF) values and

Production of arsenical bronze using speiss on the Elephantine Island (Aswan, Egypt) during the Middle Kingdom (Middle Bronze Age) (c.2000–1650 BCE)

Archaeometry, EarlyView.
Abstract This paper presents the first direct evidence of the slags produced during the cementation alloying process of Cu with speiss inside ceramic crucibles, thus representing Cu alloying with As in Middle Kingdom Egypt. The settlement deposits from the Middle Bronze Age were excavated on Elephantine Island, within modern Aswan.
