Advancements in the Synthesis of Building Block Materials: Experimental Evidence and Modeled Interpretations of the Effect of Na and K on Imogolite Synthesis
(AMER CHEMICAL SOC, 2017)The effects of Na/K substitution during the synthesis of imogolite nanotubes (NTs) were studied using a combination of structural and surface analyses. These were complemented with molecular dynamics (MD) and DFT computational ... -
Macroscopic nonclassical-state preparation via postselection
(American Physical Society, 2017)Macroscopic quantum superposition states are fundamental to test the classical-quantum boundary and present suitable candidates for quantum technologies. Although the preparation of such states has already been realized, ... -
Stimulated Raman adiabatic control of a nuclear spin in diamond
(American Physical Society, 2017)Coherent manipulation of nuclear spins is a highly desirable tool for both quantum metrology and quantum computation. However, most of the current techniques to control nuclear spins lack fast speed, impairing their ... -
The power of a control qubit in weak measurements
(NATURE PUBLISHING GROUP, 2017)In the late 80 s, a curious effect suggested by Aharanov et al. was found to lead to an anomalous amplification based on quantum measurements of weakly coupled systems. In this paper, we investigate the quantum control of ... -
Draft genome of Chilean honeybee (Apis mellifera) gut strain Lactobacillus kunkeei MP2
(American Society for Microbiology, 2014)Here, we report the first draft genome sequence of Lactobacillus kunkeei strain MP2, isolated from a Chilean honeybee gut. The sequenced genome has a total size of 1.58 Mb distributed into 44 contigs and 1,356 protein-coding ... -
Remnants of native forests support carnivore diversity in the vineyard landscapes of central Chile
(Cambridge University Press, 2018-03)Carnivores play an important role in ecosystem functioning as apex predators. However, most carnivore species are threatened or have been extirpated in human-dominated landscapes. The Mediterranean region of central Chile ... -
On the proportional abundance of species: Integrating population genetics and community ecology
(Nature Publishing Group, 2017)The frequency of genes in interconnected populations and of species in interconnected communities are affected by similar processes, such as birth, death and immigration. The equilibrium distribution of gene frequencies ... -
Macroecological factors shape local-scale spatial patterns in agriculturalist settlements
(The Royal Society, 2017)Macro-scale patterns of human systems ranging from population distribution to linguistic diversity have attracted recent attention, giving rise to the suggestion that macroecological rules shape the assembly of human ... -
Inducing Porosity on Hollow Nanoparticles by Hypervelocity Impacts
(American Chemical Society, 2017)The large surface-to-volume ratio of hollow palladium nanoparticles (hNPs) offers room to improve their hydrogen storage capacity as well as their catalytic activity. However, a less explored possibility is to use, in ... -
