Crude flake graphite powder (45 um, 99%), sulfuric acid (H2SO4, 98.08%), sodium nitrate (NaNO3), potassium permanganate (KMnO4), hydrogen peroxide (H2O2 30%), hexadecyl trimethyl ammonium bromide (CTAB), sodium dodecyl benzene sulfonate (SDBS
), ascorbic acid, manganese(II) sulfate monohydrate (MnSO4.H2O, 99%), and hydrochloric acid (HCL 36 %), were obtained from Tianjin Kemiou Chemical Reagent Co., Ltd.
A total of 10 g of temperature-responsive PU and 1 g of SDBS
were dispersed in 90 g deionized water in a three-neck flask equipped with a mechanical stirrer and a thermometer.
'In the next few weeks, two more newly built 35 meter SDBs
from France would be injected into the NN fleet.
Load-deflection curves were observed, and the ultimate shear load-carrying capacities of controlled beams (DBs and SDBs
) were worked out by applying single-point load "P" at two different shear-span ratios (a/d) = 1.0 and 3.0, respectively, where "a" denotes the shear span of the beam and "d = 198 mm" denotes the effective depth of the beam.
The typical procedure is as follows: 0.25 g [Fe.sub.3][O.sub.4] was dispersed in 100 ml deionized water with the help of SDBS
(25 mg) and mechanical agitation.
For the task, SDS, CTAB, SDBS
, and Triton X-100 surfactants were tested and the anionic surfactant SDS was chosen because of its low critical micellar concentration (cmc of 0.0082 mol x [L.sup.-1] in water), which permits to use lower surfactant concentration.
The as-prepared samples are referred to a (without surfactant), b (with CTAB as surfactant), c (with SDBS
as surfactant), and d (with DEA as surfactant), respectively.
For manufactured products, including manufactured, processed and preserved foodstuffs (such as bread, butter, cheese, bacon and ham), production data (in US dollar terms) have been collected at the 4-digit level of ISIC Revision 4 (ISIC4) from the OECD Structural and Demographic Business Statistics (SDBS
) database and the UNIDO INDSTAT4 database.
The specimen also was rubbed, polished and etched with the solution of picric acid and sodium dodecyl benzene sulfonate (SDBS
) when the DSC experiment was completed.
Also, this dividend is payable to those holders of SDBs
(ISIN SE0001134529) (SDRs) who on the record date of 31 March 2017 are entered on the SDR register kept by Euroclear Sweden as holders of SDRs or holders of rights.
The analysis of SMO IR-spectrums, demonstrating maximum (Lonzest) and lowered (SP-80, Experse) interphase activity, has shown that these products have the identical maxima of absorption, corresponding to reference data ("Spectral Database for Organic Compounds SDBS
