The dextran oxidation by the sodium periodate is a catalysis-free aqueous reaction which yields a polyaldehyde dextran that can serve as a macromolecular cross-linker for amino group bearing polymers to form hydrogel. The functional groups of dextran and Odex were identified by FTIR spectra. The broad peak at the region of 3500 cm−1 corresponded to the OH stretching vibration of the polysaccharide in both the spectra. However, a decrease in the intensity of OH in the Odex spectra might be attributed to the conversion of OH group into CHO group during oxidation reaction. Similarly, the peak at 2920 cm−1 was assigned to C–H stretching vibrations of dextran and Odex. The sharp peak appears at 1003 cm−1 and shoulder peak at 1143 cm−1 were the characteristic band of asymmetrical C–O–C vibrations. Small shoulder peaks at 816 and 920 cm−1 confirmed the presence of (1→3)-α-d-glucan, a ring structure of glucose molecules. The information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones
