Insight to Cellulose–Polycarboxylic Acid Intermolecular Interactions Using TG and DSC Thermal Analysis Tools
نویسندگان
چکیده
Interactions between polycarboxylic acids and cellulose was evaluated by using thermogravimetric analysis (TGA) differential scanning calorimetry (DSC) profiles of their mixtures. TGA, DSC were recorded as baseline data peak shifts calculated subtracting the maximum values from that cellulose-polycarboxylic acid In DL-tartaric citric with mixtures showed largest positive +58 +23°C in derivative-TGA second peak. addition, smallest DTGA 1 area/peak 2 area ratios 0.50 1.58 respectively. dehydration +39 +21°C for acids. studied, one or more hydroxyl groups are strongly interacting solid state. The strong interactions these probably due to ability wrap round polysaccharide chains forming multiple hydrogen bonding –COOH –OH cellulose.

Comparative kinetic analysis on thermal degradation of some cephalosporins using TG and DSC data
BACKGROUND The thermal decomposition of cephalexine, cefadroxil and cefoperazone under non-isothermal conditions using the TG, respectively DSC methods, was studied. In case of TG, a hyphenated technique, including EGA, was used. RESULTS The kinetic analysis was performed using the TG and DSC data in air for the first step of cephalosporin's decomposition at four heating rates. The both TG an...
متن کاملEnergy decomposition analysis of covalent bonds and intermolecular interactions.
An energy decomposition analysis method is implemented for the analysis of both covalent bonds and intermolecular interactions on the basis of single-determinant Hartree-Fock (HF) (restricted closed shell HF, restricted open shell HF, and unrestricted open shell HF) wavefunctions and their density functional theory analogs. For HF methods, the total interaction energy from a supermolecule calcu...
متن کاملAn Old Insight Leads to New Tools
seems an unlikely person to help transform the statistical rigor of experiments in the vanguard of microarray analyses and proteomics. For one thing, he died almost 250 years ago in Tunbridge Wells, an English town that remains sleepy even today. And rather than being a scientist, Bayes was a nonconformist minister. Yet today's microarray and proteomic researchers increasingly use the statistic...
متن کاملFurther analysis and comparative study of intermolecular interactions using dimers from the S22 database.
Accurate MP2 and CCSD(T) complete basis set (CBS) interaction energy curves (14 points for each curve) have been obtained for 20 of the dimers reported in the S22 set and analytical Morse curves have been fitted that can be used in developing updated density functional theory (DFT) and force field models. The magnitude and the effect of the basis set superposition error (BSSE) were carefully in...
متن کاملBifurcation and Chaos in Size-Dependent NEMS Considering Surface Energy Effect and Intermolecular Interactions
The impetus of this study is to investigate the chaotic behavior of a size-dependent nano-beam with double-sided electrostatic actuation, incorporating surface energy effect and intermolecular interactions. The geometrically nonlinear beam model is based on Euler-Bernoulli beam assumption. The influence of the small-scale and the surface energy effect are modeled by implementing the consistent ...
