Abstract: Few-walled carbon nanotubes (FWNTs) can be synthesized in a simple chemical vapor deposition (CVD) system using a mixture of methanol and ethanol as the carbon source. In preferred embodiments, the present invention uses an ethanol/methanol mixture as the carbon source so that few walled nanotubes (FWNTs) with high purity can be prepared following a simplified purification process. Under the growth conditions of the present invention, ethanol is believed to act as the carbon source while methanol is believed to act as a “carbonaceous impurity remover” to remove the impurities deposited on a support (e.g., MgO) and thereby hinder the formation of such impurities.

Abstract: A method of measuring a hemoglobin parameter of a test sample of blood comprises diluting and lysing a test sample. Then, a temperature corresponding to the test sample is obtained. The diluted and lysed test sample is then delivered to a cuvette, and a spectrophotometer determines the absorbance and/or transmittance of the sample in the cuvette. With the absorbance and/or transmittance of the test sample, a first measurement of the hemoglobin parameter of the test sample is obtained. After a first measurement of the hemoglobin parameter is obtained, a processor determines a corrected measurement of the hemoglobin parameter of the test sample. The corrected measurement is a function of the measured temperature that corresponds to the test sample and the first measurement of the hemoglobin parameter. The method of measuring a hemoglobin parameter is valid over a range of test sample temperatures.
