Permafrost and methane hydrates are large, climate-sensitive old carbon reservoirs that have the potential to emit large quantities of methane, a potent greenhouse gas, as Earth continues warm. We present ice core isotopic measurements (Δ14C, δ13C, δD) from last deglaciation, which is partial analog for modern warming. Our results show emissions in response deglacial warming were small (<19 teragrams per year, 95% confidence interval) argue against similar future also indicate biomass...
Objectives The aim of this study was to investigate factors affecting ablative efficiency high intensity focused ultrasound (HIFU) for adenomyosis. Materials and methods In all, 245 patients with adenomyosis who underwent guided HIFU (USgHIFU) were retrospectively reviewed. All dynamic contrast-enhanced magnetic resonance imaging (MRI) before after treatment. non-perfused volume (NPV) ratio, energy factor (EEF) greyscale change set as dependent variables, while the possibly ablation...
Understanding how sediment transport and storage will delay, attenuate, even erase the erosional signal of tectonic climatic forcings has bearing on our ability to read interpret geologic record effectively. Here, we estimate transit times in Australia's largest river system, Murray-Darling basin, by measuring downstream changes cosmogenic 26Al/10Be/14C ratios modern sediment. Results show that sediments have experienced multiple episodes burial reexposure, with cumulative lag exceeding 1 Ma...
A novel Z-scheme TiO<sub>2</sub>-OV-BiOCl shows better and excellent photocatalytic degradation for imidacloprid than type-II TiO<sub>2</sub>/BiOCl.
We prepared antimony metal films via electrodeposition, followed by the synthesis of Sb2S3 through a chemical vapor phase reaction. Finally, an Sb2O3 film was deposited onto using bath method, successfully constructing heterojunction photocathode Sb2S3/Sb2O3; synthesized Sb2S3/Sb2O3 is classified as Type I heterostructure. The resulting exhibited photocurrent density −0.056 mA cm−2 at −0.15 V (vs. RHE), which 1.40 times higher than that alone under simulated solar illumination. Additionally,...
Tungsten trioxide (WO3) films doped with 0.25 atom% tellurium synthesised by a sol-gel route, show strong transient photocurrents under chopped sub-bandgap illumination (hnu=1.8 eV<Eg) at low bias potentials from 0.2 to 0.7 V; such effects are ascribed the presence of localized narrow band (NB) between VB and CB in this material.
Automobile shredder residue (ASR) pyrolysis produces solid, liquid, and gaseous products, particularly oil gas, which could be used as renewable alternative energy resources. Due to the primary reaction not being complete, yield of product is low. The tar comprises chemically unstable volatiles before condensing into liquid. Understanding characteristics volatile products will aid design improvement subsequent processes. In order accurately analyze chemical yields ASR pyrolysis,...
In this work, chlorine doped Bi–BiO<sub>2−x</sub> (Cl–Bi–BiO<sub>2−x</sub>) was prepared by a one-step solvothermal method using sodium bismuthate (NaBiO<sub>3</sub>·2H<sub>2</sub>O) as Bi source without the addition of surfactant.
We describe progress in developing a novel miniaturized laser-heated “microfurnace” aimed at preparing ultra-small (∼5 μg) graphite samples from CO 2 (Smith et al. 2006, 2007, 2010). Recent effort has focused on automation of the process using LabVIEW interface, which permitted feedback control catalyst temperature as reaction proceeds and logging parameters. trialed number different pure iron catalysts well Fe O 3 (which is reduced situ to iron) discuss rates. studied morphology by scanning...
Abstract. Cosmic rays entering the Earth's atmosphere produce showers of secondary particles such as protons, neutrons, and muons. The interaction these with oxygen-16 (16O) in minerals ice quartz can carbon-14 (14C). In glacial ice, 14C is also incorporated through trapping 14C-containing atmospheric gases (14CO2, 14CO, 14CH4). Understanding production rates situ cosmogenic important to deconvolve signals both which contain valuable paleoenvironmental information. Unfortunately, by muons...
Abstract. Measurements of carbon-14-containing carbon monoxide (14CO) in glacial ice are useful for studies the past oxidative capacity atmosphere as well reconstructing cosmic ray flux. The 14CO abundance represents combination trapped atmospheric and situ cosmogenic 14CO. systematics production retention not fully quantified, posing an obstacle to interpretation core measurements. Here we provide first comprehensive characterization at accumulation site (Summit, Greenland), including...
Abstract. Important uncertainties remain in our understanding of the spatial and temporal variability atmospheric hydroxyl radical concentration ([OH]). Carbon-14-containing carbon monoxide (14CO) is a useful tracer that can help characterization [OH] variability. Prior measurements 14CO ([14CO] are limited both their extent, partly due to very large air sample volumes have been required for (500–1000 L at standard temperature pressure, STP) difficulty expense associated with collection,...
Carbon-14 is produced in the atmosphere when neutrons from cosmic-ray air showers are captured by nitrogen nuclei. Atmospheric carbon-14 becomes trapped bubbles polar ice as compacted snow (firn) transforms into ice. also situ grains penetrating and muons. Recent core measurements indicate that carbon monoxide (CO) phase, dominated cosmogenic component at most coring sites. Thus, it should be possible to use ice-bound CO reconstruct historical flux of cosmic rays Earth, without transport...
