Clouds, airplanes, trucks and people: carrying radioisotopes to and across Mexico [PDF]

open access: yes, 2015
The aim of this paper is to describe the early stages of Mexican nuclearization that took place in contact with radioisotopes. This history requires a multilayered narrative with an emphasis in North-South asymmetric relations, and in the value of ...

Clustering of phosphorus atoms in silicon [PDF]

open access: yesNonlinear Phenom. Complex Syst.. Vol.11, No.3, (2008) 316-386, 2006
To explain the effect of electron density saturation at high phosphorus concentrations the model of negatively charged phosphorus clusters was compared with the experimental data. A number of negatively charged clusters incorporating a point defect and phosphorus atoms were investigated at temperatures of 920 and 1000 Celsius degrees.

A basin‐wide carbon‐related proxy dataset in arid China

open access: yesGeoscience Data Journal, Volume 12, Issue 1, January 2025.
Here we present a dataset of carbon‐related proxy for the Shiyang River Basin, which involves profile sediment, surface sediment, and groundwater samples, including age, TOC, TN, C/N, IC, δ13Corg, δ13Ccarb, and δ18O indicators. We have learned that the terminal lakes in the Shiyang River Basin have generated important inorganic carbon sinks and some ...

Strongly Modulated Ambipolar Characteristics of Few-layer Black Phosphorus in Oxygen [PDF]

open access: yesarXiv, 2016
Two-dimensional black phosphorus has been configured as field-effect transistors, showing an intrinsic symmetric ambipolar transport characteristic. Here, we demonstrate the strongly modulated ambipolar characteristics of few-layer black phosphorus in oxygen.

Genetic variation and phenotypic plasticity of nutrient re-allocation and increased fine root production as putative tolerance mechanisms inducible by methyl jasmonate in pine trees [PDF]

open access: yes, 2014
1. Plant plastic responses to herbivore damage may include rapid, active reallocation of plant resources to reduce the impact of herbivory on future plant fitness. However, whether these inducible tolerance responses can be extended to pine trees and how
