The distribution and amount of carbon in the largest peatland complex in Amazonia [PDF]

open access: yes, 2014
This work was funded by NERC grants NE/I021217/1 and NE/J50001X/1.Peatlands in Amazonian Peru are known to store large quantities of carbon, but there is high uncertainty in the spatial extent and total carbon stocks of these ecosystems.

Preserving Proton Resolution Under Cryogenic Dynamic Nuclear Polarization for Biomolecular Solid‐State NMR

open access: yesAngewandte Chemie, EarlyView.
High‐resolution proton detection is preserved under cryogenic dynamic nuclear polarization (DNP) by combining fast MAS, extensive deuteration and selective methyl protonation. This strategy enables proton‐detected structural studies of biomolecular solids with enhanced sensitivity under DNP conditions.

Medium Spatial Resolution Satellite Imagery to Estimate Gross Primary Production in an Urban Area

open access: yesRemote Sensing, 2010
Remote sensing data with medium spatial resolution can provide useful information about Gross Primary Production (GPP), especially on the scale of urban areas. Most models of ecosystem carbon exchange that are based on remote sensing use some form of the

COMPARISON OF THE USE OF SENTINEL-1 SAR AND ALOS-2 PALSAR-2 IN MANGROVE ABOVEGROUND BIOMASS ESTIMATION IN SAN JUAN, BATANGAS, PHILIPPINES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
This study compares the potential of Sentinel-1 and ALOS-2 PALSAR-2 in estimating mangrove aboveground biomass (AGB) in San Juan, Batangas, Philippines. Mangrove forests are essential coastal ecosystems that are facing growing threats.

La mortalidad de párvulos y la mortalidad infantil en Cataluña (1700-1860)

open access: yesPoblación y Salud en Mesoamérica, 2023
Hay muy pocos trabajos sobre la mortalidad infantil en Cataluña. Por ello, se pretende estudiar la mortalidad de párvulos (infantes menores de 12 años) y la mortalidad infantil (infantes menores de 1 año) a partir de una recopilación sistemática de los ...

Out‐of‐Plane Strain‐Decoupled Architecture for High‐Fill‐Factor Stretchable OLED Displays

open access: yesAdvanced Functional Materials, EarlyView.
A vertically decoupled multilayer SOLED architecture separates emissive pixel islands from deformable interconnects, allowing low‐modulus elastomeric layers to accommodate applied strain and suppress strain transfer to the OLED region. This design, combined with transparent hybrid encapsulation, enables a high fill factor (∼75%), stretchability ...

From Pores to Pavement: Advanced Modeling of Aluminosilicates for Scalable Carbon Capture in Concrete

open access: yesAdvanced Science, EarlyView.
This study presents a transferable modeling framework for carbon capture using aluminosilicates, integrating Universal Isotherm Modeling with experimental data. It reveals how ultramicropores, alumina content, and amine functionalization influence CO2 adsorption energetics.
