Nanoscale zero-valent iron (nZVI) particles have excellent capacity for in situ remediation of groundwater resources contaminated by a range organic and inorganic contaminants. Chlorinated solvents are far the most treated compounds. Studies at column, pilot, field scales reported successful decrease contaminant concentration upon injection nZVI suspensions zones. However, application is from optimized, particularly treatments at—or close to—the source, presence residual nonaqueous liquid...
More sustainable technologies in agriculture are important not only for increasing crop yields, but also reducing the use of agrochemicals and improving energy efficiency. Recent advances rely on computer vision systems that differentiate between crops, weeds, soil. However, manual dataset capture annotation is labor-intensive, expensive, time-consuming. Agricultural robots provide many benefits effectively performing repetitive tasks faster more accurately than humans, despite advantages...
Commonly used methods to visualize the biological structure of brain tissues at subcellular resolution are confocal microscopy and two-photon microscopy. Both require slicing sample into sections a few tens micrometers. The recent developments in X-ray microtomography enable three-dimensional imaging sub-micrometer isotropic with larger samples. In this work, we developed compared original staining protocols improve contrast for vitro mouse neuron imaging. Using Golgi's method stain neurons...
X-ray computed tomography (CT) is an imaging technique intended to obtain the internal structure and three-dimensional representation of a sample. In general, parallel-beam CT reconstruction algorithms require precise angular alignment knowledge exact axis rotation position. Highly brilliant sources with ever-increasing data-acquisition rates demand optimized techniques avoid compromising in situ data analysis. This paper presents method automatically align orientation linear position setup,...
Time-resolved X-ray microtomography is a cutting-edge techinque that enables the study of dynamic events, such as sample deformation, mineral reaction and fluid migration through real samples. For first time, it now possible to identify quantify pore scale in correlate them macroscales behaviours system. The goal this work provide illustrative examples what achievable with technique applied flow porous media, more specifically, groundwater remediation. This already available at Imaging...
Abstract Due to recent developments on synchrotron sources, time-resolved experiments are favored by fourth-generation machines. In particular, X-ray tomography beamlines can now perform complete in less than one second. MOGNO, the nano and microtomography beamline at Sirius, is designed for situ operando experiments. The first tested environmental cell a injection system porous media materials. This composed flow with fluid control pressure feedback. be used pore up 750 PSI. To increase...
Abstract MOGNO is the micro and nano tomography dedicated beamline at Sirius, operating three specific energies: 21.5, 39.0, 67.7 keV. Its optics composed by a set of mirrors (pre-KB + KB set), delivering 3 mrad cone beam, coming from 100x100 nm 2 main source. The pre-KB mirror must be aligned to produce secondary source 0.3 x 800.0 µm , however, such an alignment challenging, as deviations it adverse effects on beamline’s source, enlarging it. Moreover, evaluate nanofocus novel strategy...
