Electrocoagulation (EC) of synthetic groundwater was conducted using a sacrificial aluminum electrode in flow-through EC reactor with short retention times (<1 min) under varying hydrodynamic and electrochemical conditions. The treated water allowed to settle for 24 h achieved silicate removal up 50 ± 4%, hardness 11 1%. Physical, chemical, characterization performed explore changes surface morphology composition. Electrochemical impedance spectroscopy (EIS) showed that chemical reactions at...
The anti-soiling (AS) performance of highly reflective, superhydrophilic (SPH, 0° water contact angle) coated mirrors was characterized and compared with that superhydrophobic (SP, >165° mirrors. A simple one-step nanotextured silica nanoparticle coating on a mirror exhibited SPH properties associated hydrophilic rough surfaces. Another surface post-functionalized low-surface-energy ligand molecules displayed SP behavior. Both mirrors, no solar reflectance loss, demonstrated excellent AS...
Elemental Cu nanoparticles in aqueous solution were synthesized by a biological process using anaerobic metal-reducing bacteria and chelator capping molecules.
We evaluate the effectiveness of an aluminum-based electrocoagulation pretreatment system to remove dissolved silica and hardness. Silica hardness limit water recovery during membrane-based desalination applications when exceed solubility generate scale on membrane surface. show that simultaneous removal nearly all (95 ± 4%) a significant amount (40–60%) occurs with hydraulic residence time 2 h charge loading between 0 1200 C/L. Increasing maximized (58 8%) via formation larger flocs, which...
Iron electrocoagulation (Fe-EC) performance often declines with time, producing lower contaminant removal efficiencies and higher energy requirements due to formation of a fouling layer on the electrodes. Here, we investigate effectiveness polarity reversal restore Fe-EC performance. A thin, porous iron oxide initially forms anode, thickening into dense, over 150-μm thick crystalline after extended operation. This restricts dissolution diffusion Fe ions bulk solution, thus increasing anode...
Volatile organic compounds (VOCs) in biological samples originate both from exogenous and endogenous sources. Recent studies have highlighted their potential as cancer biomarkers, emphasizing the need for accurate detection methods clinical settings. However, analysis of VOCs whole blood (WB) remains challenging due to complex matrix effects caused by protein-VOCs binding phenomenon lack standardized sample preparation protocols. Therefore, this study suggests a method advanced VOC WB...
An aluminum (Al)-based electrocoagulation (EC) system can effectively remove dissolved silica and hardness in groundwater. The effectiveness of Al-EC terms pollutant removal, Faradaic efficiency, energy consumption depends on the interfacial electrolysis or passivation electrode water. Thus, understanding reaction at liquid/electrode interface during operation is important for sustainable EC deployment. A continuous flow-through was tested with various groundwater simulants, i.e., chloride...
Atmospheric pressure plasma (AP) treatment, using an open-air jet of ionized CO2, N2, or air, was applied to AZ91D Mg alloy surfaces investigate its effects on primer coating adhesion and corrosion resistance. The CO2 air AP treatments formed O- C-rich surface layer (Mg-O-C) consisting agglomerated nanoparticles pits with a depth few microns increasing the roughness by 6–8 times compared reference 600 grit-finished surface. Then, three commercial primers, zinc phosphate (ZnP),...
Highly transparent, superhydrophobic nanoparticle-textured coatings with engineered surface roughness significantly decrease the adhesion force of dust particles on surface, resulting in soil and repellent performance.
Abstract Solar‐thermal driven desalination based on porous carbon materials has promise for fresh water production. Exploration of high‐efficiency solar devices not solved issues practical application, namely complicated fabrication, cost‐effectiveness, and scalability.

Mg alloy corrosion susceptibility is a major issue that limits its wide industrial application in transport, energy and medical sectors. A corrosion-resistant layer containing crystalline MgCO3 was formed on the surface of AZ91D by Li salt loading thermal CO2 treatment. Compared to uncoated surface, exhibited up ∼15-fold increase resistance according electrochemical results 3.5 wt% NaCl solution ∼32% decrease wear rate compared untreated AZ91D. The improved attributed formation <10 μm thick...
Phosphoric acid sludge contains (∼54% P2O5) and solid precipitates including rare earth elements (REEs) at concentrations of ∼2200 ppm. Low-cost recovery valuable P2O5 simultaneous separation could be an economically feasible approach to recovering REEs while increasing the production phosphoric acid. The sludge, however, is a complicated stream that cannot separated by traditional technologies because high viscosity large content (30–40%). Guided force balance model, efficient solid/liquid...
