Background: The intake of sodium, chloride, and potassium is considered important to healthy nutrition and cardiovascular disease risk. Estimating the intake of these electrolytes is difficult and usu...
Brassinosteroids are a class of plant polyhydroxysteroids with a diverse of functions in plant growth and development, while ethylene is a gaseous hormone involved in regulation of numerous physiologi...
The rare earth element (REE) partition coefficients between calcite and aqueous solution were obtained experimentally under the conditions of pH, ionic strength and REE concentration level in the par...
An analytical system using continuous-flow isotope ratio mass spectrometry (CF-IRMS) was developed to determine the stable chlorine isotope ratios (δ37Cl) for CH3Cl. By using appropriate devices for ...
Collagen/cellulose films were made by the blend solutions of collagen, cellulose in this paper. To begin with, collagen and cellulose was dissolved in 1-allyl-3-methylimidazolium chloride ([Amim]Cl). ...
The sol-gel transition of methylcellulose (MC) solution in the presence of NaCl and hexade-cyltrimethylammonium bromide (HTAB), together with MC/NaCl solution in the presence of HTAB and MC/HATB solut...
The 1H-pyrazole-3-carboxylic acid 2 was converted via reactions of its acid chloride 3 with various hydroxylamine 4a-f and carbazate derivatives 8a-c into the corresponding novel N-substituted-4-benzo...
The 1H-pyrazole-3-carboxylic acid 2 was converted via reactions of its acid chloride 3 with various hydroxylamine 4a-f and carbazate derivatives 8a-c into the corresponding novel N-substituted-4-benzo...
A simple and convenient procedure for reductive amination of aldehydes and ketones using sodium borohydride in the presence of silica chloride as an active, inexpensive, recoverable, and recyclable ca...
The effect of this correction can best be appreciated by defining the non-dimensional variablesB*5BaandT*5(T(B)2Th)/(Te2Th) and plotting these as a function ofm(Fig. 2). Values ofB*from Eqs. 2 and 3 c...
The study presented in this paper concerns the extractability of rutin into an aqueous 1-butyl-3-methylimidazolium chloride (BMIM-Cl) solution. The effects of the concentrations of BMIM-Cl, amounts of...
Prussian blue (PB) was deposited on multi-walled carbon nanotubes (MWCNT) in an aqueous solution. Multi-layer composites of the MWCNT-PB hybride material were obtained by layer-by-layer assembly with...
The heterogeneous reaction of N2O5 on mixed organic-inorganic aerosol particles was investigated using an entrained aerosol flow tube coupled to a custom-built chemical ionization mass spectrometer. L...
Breakthrough curves of C1 and 3 ~ 2we0re o btained during steady unsaturated flow in five lysimeters containing an undisturbed coarse sand (Orthic Haplohumod). The experimental data were analyzed in...
A pedon scale study was conducted to investigate the degree of chloride leaching from a de-watered saline soil profile in the non-irrigated wheatbelt region of south-western Australia. Within the surf...
