Synthesis and characterization of carboxyl and acetal latexes by emulsion polymerization. Application to the production of latex-protein complexes for detecting chagas disease [PDF]

open access: yes, 2012
Monodisperse polymer particles with carboxyl and acetal functionalities were synthesized through a two-step emulsion polymerization process. In the first step, latex particles were synthesized by batch emulsion polymerization of styrene (St); and in the ...

Microstructural Controls on Geothermal Reservoir Host Rock Responses to Elevated Pressures and Temperatures

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rock microstructure controls geothermal fluid flow within reservoirs hosted in active volcanic environments and as such it is necessary to constrain the microstructural evolution of rocks at elevated pressure and temperature conditions. Despite Andean geothermal systems hosting numerous high enthalpy geothermal plays, there remains a paucity ...

Experimental and Numerical Investigation of the Characteristic Length Governing Soil Evaporation in Layered Sands

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract In arid and semi‐arid regions, ecosystems exist with shallow water tables, where evaporation is a key component of the water balance. However, systematically addressing soil evaporation remains challenging due to differing interpretations of the mechanisms that control it.

Seed Traps Differ in Species Numbers, Seed Densities and Contamination but Mostly Do Not Reflect Grazing in a Pampa Grassland

open access: yesApplied Vegetation Science, Volume 29, Issue 2, April/June 2026.
Ground traps are more effective than adhesive traps in measuring seed rain species richness and density. They also allow to more closely resemble the seed production of the surrounding vegetation. Management‐driven differences in the vegetation were not reflected by the seed rain of any trap type, but the advantages and disadvantages of different trap ...

When Proximity Falls Short: Inequalities in Commuting and Accessibility by Public Transport in Santiago, Chile

open access: yesGeographical Analysis, Volume 58, Issue 2, April 2026.
ABSTRACT Traditional measures of urban accessibility often rely on static models or survey data. However, location information from mobile networks enables large‐scale, dynamic analyses of how people navigate cities. In this study, we employ eXtended Detail Records (XDRs) from mobile phone activity to analyze commuting patterns and accessibility ...

Computer simulation of platelet activation in a pulsatile ventricular assist device, through finite elements and a simplified geometry [PDF]

open access: yes, 2017
Ventricular assist devices are a technological solution for patients who suffer from cardiac insufficiency and await a transplant. In this work, a new design of an implantable pulsatile blood pump is analyzed in terms of blood damage, by means of finite ...

Effect of Hydrophobic Coating on Hagen-Poiseuille Flows

open access: yesJournal of Applied Fluid Mechanics, 2016
The effect of a hydrophobic coating on the flow through circular pipes with Newtonian fluids has been investigated. Velocity fields inside a pipe were experimentally determined by the particle image velocimetry (PIV) technique. The test fluid presented a
