Reversibility of the treatment Comparison of the difference between the initial mass of the sample and its mass after soaking and drying enabled to indicate the compounds which are susceptible to leaching thereby giving the possibility to reverse the treatment, and those which allow permanent wood pro...
Recently, Heiz and coworkers have applied MB techniques in order to perform kinetic measurements on mass-distributed [325] (CO oxidation) and subsequently on mass-selected (CO–NO reaction) [178] Pd clusters on MgO(1 0 0)/Mo(1 0 0). An interesting complementary approach from a catalytic ...

The sense organs consist of a mass of calcium carbonate crystals (otoconia) that overlie a membrane that is innervated with hair cells. Motion of the crystals relative to the hair cells bends the hair cells, and this bending modifies their firing rates and so provides information on linear ...
The molecular mass of glucose is 180 g/mole. How will you make a 0.25 M glucose solution?MolarityMolarity (M) is a commonly used unit of measurement for calculating the concentration of a solution. Molarity is measured in moles per liter (moles/L) and indicates th...
BOSTON, Mass. -- By Lee Han-soo/Korea Biomedical Review correspondent -- Bayer Pharmaceuticals has recently made a significant shift in its strategic focus by placing a strong emphasis on oncology research and development.Recognizing the urgent need for
Tensor additive calculations of the molar Kerr constants (mKcalc) were performed using the data of [27, 32]. Ab initio quantum-chemical calculations were performed with the aid of the GAUSSIAN-98 software. The IR spectra were recorded in KBr on a Philips PU-9804FTIR spectrometer. The ...
About 15 mg of the sample was dissolved in CDCl3 and DMSO-d632. The ES-MS spectra were recorded on an ion trap LCQ Advantage Max mass spectrometer (Thermo Electron Corporation)33. The melting point apparatus (Stuart SMP10) was used to determine the melting points of the synthesized ...
1b. As can be seen, the first peak observed at 2θ = 1.0–2.5° is a relatively sharp peak attributed to the semi-long-range ordered hexagonally arranged mesostructure of the silica15,28. Convenience in accessibility of adsorption sites can lead to overcome the mass transfer problems ...
