Bioplastics aim to substitute conventional plastics in most applications, a critical one being the collection of organic wastes for composting or anaerobic degradation. The biodegradability six commercial bags composed PBAT PLA/PBAT blends and certified as compostable [[1]EN 13432. Requirements Packaging Recoverable through Composting Biodegradation. Test Scheme Evaluation Criteria Final Acceptance Packaging.Google Scholar] was studied using 1H NMR ATR-FTIR techniques. This study aims...
The ecophysiologic role of fog in the evergreen heath-laurel 'laurisilva' cloud forests Canary Islands has not been unequivocally demonstrated, although it is generally assumed that water important for survival and distribution this relict paleoecosystem North Atlantic Macaronesian archipelagos. To determine ecosystem, we combined direct transpiration measurements tree species, obtained with Granier's heat dissipation probes, micrometeorological artificial collection carried out a 43.7-ha...
Abstract Fog precipitation has long been assumed as an additional water source in the relic laurel ecosystems of Canary Islands, located at 500–1400 m MSL. However, to what extent fog can contribute forest balance is not yet clear. Combining data from artificial catchers and a physically based impaction model, authors evaluated potential contribution captured by needle-leafed Erica arborea L. trees selected watershed Garajonay National Park (La Gomera Island) for 2-yr period (February...
Abstract Plasma polymer coatings with embedded Ag nanoparticles were deposited in a low pressure RF plasma reactor using an asymmetrical setup electrode. The was from reactive gas/monomer mixture of CO 2 /C H 4 yielding functional hydrocarbon matrix. In addition, Ar simultaneously used to sputter atoms the electrode, forming within growing influence power input, gas ratio and coating thickness on both, content nanoparticle morphology, as well distribution matrix investigated. It found that...
Close inspection of the pre-edge in oxygen near-edge x-ray absorption fine structure spectra single step, gas phase synthesized titanium oxynitride photocatalysts with 20 nm particle size reveals an additional eg resonance VB that went unnoticed previous TiO2 anion doping studies. The relative spectral weight this Ti(3d)-O(2p) hybridized state respect to and located between readily established t2g resonances scales qualitatively photocatalytic decomposition power, suggesting extra bears...
Functionalized medium-chain-length polyhydroxyalkanoates (mclPHAs) have gained much interest in research on biopolymers because of their ease chemical modification. Tailored olefinic mclPHA production from mixtures octanoic acid and 10-undecenoic was investigated batch dual (C,N) nutrient limited chemostat cultures Pseudomonas putida GPo1 (ATCC 29347). In a culture, where P. grown mixture (58 mol%) (42 mol%), it found that the fraction aliphatic monomers slightly lower produced during...
Soil water repellency varies nonlinearly with soil moisture, describing a versus content curve. Despite this dependence, is usually characterized by indexes measured at fixed content. We provide statistically robust yet simple method to determine range of contents, proposing alternative water‐dependent parameters derived from the molarity an ethanol droplet (MED) test. Useful correlations are found between some these proposed parameters, such case integrated area below curve, which be...
White lead (2PbCO3·Pb(OH)2), a common component in 17c. artists' painting materials, was singled out to investigate the potential of isotope abundance ratios field authentication and origin assignment. Paintings by Peter Paul Rubens, Anthony van Dyck other Old Masters Northern Southern schools were chosen for this study. An interdisciplinary approach using both analytical instrumental methods, art technological historical knowledge. Minute samples taken from paintings selected collections...
Abstract South Florida's Miami‐Dade agricultural area is located between two protected natural areas, the Biscayne and Everglades National Parks, subject to costliest environmental restoration project in history. Agriculture, an important economic activity region, competes for land water resources with efforts Miami's urban sprawl. The objective of this study, understanding quality interactions use shallow regional aquifer, critical reduction agriculture's potentially negative impacts. A...
Among different alternatives, dielectric capacitance sensors may provide simultaneous readings of the volumetric water content and soil solution electrical conductivity in same sample volume at low cost. Reliability capacitive be questioned, however, due to signal frequency which they work, also because effects on estimation. In this study we evaluated commercial WET Sensor (Delta‐T Devices Ltd., Burwell, UK) compared with time domain reflectometry (TDR) three volcanic soils textures....
Abstract Polycrystalline tungsten-doped titanium dioxide nanopowders within a dopant concentration of 0-1 at.% were prepared by one-step flame spray synthesis (FSS). Mixtures tetra-isopropoxide dissolved in ethanol and tungsten hexacarbonyl solubilized tetrahydrofuran used as precursors. The specific surface area (SSA) the powders was between 40 130 m
Research oriented toward understanding the hydrologic functioning of relict “laurisilva” evergreen forests is scarce. This study focused on analysis temporal changes in soil water status under such humid subtropical stands and explored to what extent fluxes may explain topsoil dynamics. Hydrologic (potential evapotranspiration, canopy fog dripping, rainwater below canopy) were computed for a 2‐yr period using situ micrometeorological measurements Garajonay National Park cloud forest (Canary...
Understanding the hydrological functioning of tidally influenced floodplain forests is essential for advancing ecosystem protection and restoration goals in impacted systems. However, finding direct relationships between basic inputs hydrology hindered by complex interactions surface water, groundwater, atmospheric fluxes a variably saturated matrix with heterogeneous soils, vegetation, topography. Thus, an explanatory method identifying common trends causal factors required. Dynamic factor...
We present the results of fog water collection obtained with cylindrical gauges at three locations on northern side Tenerife island (Spain): La Esperanza (1093 m a.s.l.), Taborno (1015 and El Gaitero (1747 a.s.l.). Concomitant meteorological variables were also measured. show that precipitation was more frequent than rainfall. However, volumes frequency daily varied among studied sites, usually not exceeding 10–40 L d−1/m2 collecting surface. In Esperanza, harvesting occurred frequently, but...
