In this study, the absorption properties of CO2 in seven different solid amine absorbents were measured. The specific characteristics, such as capacity, absorption/desorption rate, cyclic cycle decay effect, temperature reaction absorber, and optimal conditions for process This occurred at two temperatures—either 296.15 or 313.15 K—while desorption was raised to 348.15 K. amines (TEPAN E-100AN) demonstrated higher capacity than others under these conditions. Our testing showed high...
New acrylic PSAs with a high flexibility were synthesized using 2-(2-ethoxyethoxy)ethyl acrylate (EEA), an ethylene glycol-based acrylate. Compared to based on 2-ethylhexyl (EHA) and octyl (OA), PSA EEA was found form physical crosslinking due improved chain entanglement increased secondary bonding by the glycol hydroxyl groups. These properties showed behaviors similar those caused crosslinking, which elasticity of resulted in fast recovery rate characteristics more than 70%. In addition,...
The physical solubility and diffusivity of N2O CO2 in aqueous sodium glycinate (SG) solutions various concentrations (1.0−3.5 kmol/m3) temperatures (303.15−323.15 K) were reported. kinetics the reaction between SG has been studied using absorption data measured by a wetted-wall column apparatus at concentrations. second-order rate constant with was determined to be k2(m3 kmol-1 s-1) = 1.95 × 1013 exp(−7670/T), where T is absolute temperature (given Kelvin). activation energy for calculated...
Our previous findings have demonstrated that bee venom (BV) has anti-cancer activity in several cancer cells. However, the effects of BV on lung cell growth not been reported. Cell viability was determined with trypan blue uptake, soft agar formation as well DAPI and TUNEL assay. death related protein expression Western blotting. An EMSA used for nuclear factor kappaB (NF-κB) (1–5 μg/mL) inhibited cells by induction apoptosis a dose dependent manner lines A549 NCI-H460. Consistent apoptotic...
The density, viscosity, and heat capacity of aqueous potassium serinate solutions were measured over the temperature range from (298.15 to 353.15) K in mass fraction (7.2 57.3) %. Each physical property was correlated with fraction, by regression analysis, corresponding coefficients for each are presented here. surface tension solution also % at 298.15 K. In addition, solubility carbon dioxide a 14.3 (313.15, 343.15, 373.15) partial pressures CO2 ranging (0.1 400) kPa. It shown that could be...
Kinetic studies of carbon dioxide absorption into aqueous potassium alaninate (PA) solutions were performed using a stirred-cell reactor at concentrations ranging from 1.0 to 3.0 M and temperatures 293.15 313.15 K. In the present work, salt alanine was suggested as an energy-efficient absorbent for CO2 capture. Densities viscosities PA solution physical solubilities in also measured evaluate reaction rate constant. The determined following...
ABSTRACT The effect of the polymeric crosslink density on thermal conductivity an epoxy nanocomposite was investigated by adding two different diamine‐functionalized multiwalled carbon nanotubes (diamine‐MWNTs) to resin as co‐curing agents and conducting fillers. Tetramethylenediamine (TMDA)‐MWNTs resulted in with a higher than octamethylenediamine (OMDA)‐MWNTs. Interestingly, epoxy/TMDA‐MWNT nanocomposites under 1.5 wt % nanotube concentration, showed epoxy/OMDA‐MWNT same concentration...
The physicochemical properties of aqueous sodium glycinate solution such as density, viscosity, surface tension, alkalinity, and pH were measured over a wide range mass fraction (0.1 to 0.5) at T = (303.15 353.15) K. data correlated with standard equations, parameters reported along average absolute deviations.
In this study, nucleation and growth of bone-like hydroxyapatite (HAp) mineral in modified simulated body fluids (m-SBF) were induced on chitosan (CS) substrates, which prepared by spin coating Ti substrate.The m-SBF showed a two fold increase the concentrations calcium phosphate ions compared to SBF, post-NaOH treatment provided stabilization coatings.The phosphate/chitosan composite homogeneous distribution approximately 350 nm-sized spherical clusters composed octacalcium (OCP; Ca 8 H 2...
To evaluate the effects of water velocity and artificial substratum characteristics on growth rate biomass accumulation periphyton, an stream mesocosm experiment was conducted using alternative sources collected from Mangwall Stream (MW), Han River (HR), bank filtration (BFW) in Republic Korea.
