Channel Network Control on Seasonal Lake Area Dynamics in Arctic Deltas
Published 2020“…We find that monthly shrinkage rates have a pronounced structured variability around the channel network with the shrinkage rate systematically decreasing farther away from the channels. This pattern of shrinkage is predominantly attributed to a deeper active layer enhancing near-surface connectivity and storage and greater vegetation density closer to the channels leading to increased evapotranspiration rates. …”

Application of Fe<sub>3</sub>O<sub>4</sub> magnetite nanoparticles grafted in silica (SiO<sub>2</sub>) for oil recovery from oil in water emulsions
Published 2021“…Using an MD<sub>dose</sub> as low as 10 mg/L attained a %<sub>hdem</sub> in the range of 93% - 4.3% for O/W mixtures with C<sub>oil</sub> < 2000 mg/L, which slightly decreased to ~90% for higher concentrations. The reported %R<sub>oil </sub>(p-value <0.05) was >90 ± 0.1 for tests carried out with pH 7 and C<sub>sur </sub>0.1 g/L and declined at higher pH and Csur to % 86.5 due to the increase in emulsion stability. …”

Graphite and metal nitrate-infused HDPE composites for enhanced thermal performance in energy-efficient building envelopes
Published 2025“…Analysis such as Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), and dielectric spectroscopy analyses further revealed extensive interaction between filler matrices, a decrease in phonon scattering, and a positive increase in crystallinity which led to the improved thermal performance.The TGA results showed that the composite exhibited greater thermal stability, and the residue mass after the decomposition process was 9%, indicating increased carbonization and structural integrity. …”
