Photoluminescence Enhancement in Erbium Nanoparticles via Controlled Phase Transformation
Small, EarlyView.Er‐NPs synthesized by PLAL were thermally treated from 200°C to 1000°C. Annealing at 600°C produced a full transition to the cubic Er2O3 phase and removed non‐radiative surface species. This led to a fivefold increase in PL. The results show how oxidation and phase purity control the optical performance of Er‐NPs.

Journal of the Royal Anthropological Institute, EarlyView.This article analyses a new wealth tax (the IGF) in Bolivia against the backdrop of the 2019 ousting of former president Evo Morales. In doing so, it engages calls for ‘a return to politics’ in anthropology by proposing the notion of a ‘fiscal grievance politics’ as animating elite opposition to the tax in lowland Santa Cruz department. I show that the

The Gender of Fossil Fuels: Oil and Domestic Perils in Mandate Palestine
Gender &History, EarlyView.ABSTRACT This article explores the gender dynamics behind the rise of kerosene – an oil derivative – as the main domestic fuel in Mandate Palestine. It argues that these dynamics were constitutive in determining who began to use oil, where and for what purposes, in turn demonstrating that women in Palestine were the promoters and targets of a campaign ...

Meteoritics &Planetary Science, EarlyView.Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.
