In this study, a symmetric supercapacitor has been fabricated by adopting the nanostructured iron oxide (Fe3O4)-activated carbon (AC) composite as the core electrode materials. The composite electrodes were prepared via a facile mechanical mixing process and PTFE polymeric solution has been used as the electrode material binder. Structural analysis of the nanocomposite electrodes were character...

We used thermochemical equilibrium calculations in the O–S– Na–K–Cl–H system to model the speciation of volcanic gases emitted from high-temperature (1000–2000 K) silicate magmas on Io. The effects of temperature, pressure, and bulk composition of the gases are explored. The bulk compositions are based on atomic ratios observed in Io’s plasma torus and extended atmosphere, and from chondritic a...

This work investigates the sulfate and chloride resistance of cement composites (mortar concrete) manufactured using electrolyzed water. Control water-based were prepared distilled water 30 min water, respectively. These exposed to 5% Na2SO4, 3.5% NaCl, a combined mixture Na2SO4 NaCl solution for 200 days. Additionally, rebar reinforced control samples ambient air 180 days, their corrosion pote...

The two-step synthesis of sodium (2,3,5,6-tetrafluorophenoxy) diethane sulfonate (Na-TFP) is reported, starting from 2,3,5,6-tetrafluorohydroquinone as the precursor. Compared with conventional aqueous electrolytes such 0.5 m NaClO4 and Na2SO4, solution Na-TFP provides higher ionic conductivity over a wide range temperature (e.g., >60 mS cm−1 at 20 °C >70 30 °C) wider electrochemical stability ...

In this paper, chitosan was grafted with acrylic acid and positively charged elements, a series of reinforced nanofiltration membranes were prepared by coating modified polymer polysulfone ultrafiltration membrane as support. The structure derivatives polymers characterized infrared spectrum, the scanning electron microscope atomic force microscope. performance composite closely related to elec...

Polyelectrolyte multilayers (PEMs) are highly promising materials as selective separation layers on the inside of hollow fiber membranes. We investigate forward osmosis (FO) performance poly(4-styrene sulfonate) (PSS)/poly(allylamine) (PAH)- and PSS/poly(ethylene imine)-based PEM membranes apply different draw solutions. The show properties, demonstrated by their retention behavior under nanofi...

Concern has been raised about green discoloration of injection-site lesions in chuck muscles in modified-atmosphere packages. Objectives were: 1) to recreate green lesions, 2) to compare the severity of discoloration of injection-site lesions in chucks from carcasses of control or vitamin E-supplemented steers, and 3) to identify pigment(s) responsible for discoloration via in vitro color react...

The original composition of Laguocuo Salt Lake was found in the mirabilite area 15 °C isothermal phase diagrams Li+, Na+, K+//Cl−, SO42−-H2O system. Four phases comprise evaporation procedure. first stage is unsaturated except for carbonate. second made up sodium chloride, mirabilite, and borax precipitate simultaneously, where halogenation rate 31.58%, water loss 68.32%. penultimate step lithi...

To 80 ml 37% aqueous formaldehyde and 80 ml concentrated HCl solution, di-tertbutyl(chloro)phosphane (8.2 ml, 43.0 mol) was added and the mixture was heated to 100 ̊C and stirred overnight. The solution was allowed to cool, then neutralized with NaOH (14 g) and NaHCO3 (7.0 g), extracted with CHCl3 (200 x 3 ml), washed with brine (100 ml), dried with Na2SO4 and the solvent was removed under reduc...
