A minicomputer controlled inelastic and total intensity light scattering spectrometer for polymer characterization
نویسندگان
چکیده
2014 A self contained apparatus has been described that allows both static and dynamic properties of polymers in solution to be measured by total intensity and quasi-elastic light scattering. Details of the testing and calibration have been given both as a function of scattering angle (0 = 20 ~ 140°) and temperature. The dynamic measurements are carried out on line using a PDP 11/34 minicomputer and spectral analysis using fast Fourier Transformation has been carried out up to 50 kHz for polystyrene latex spheres and polystyrene/benzene solutions. For the latter random coil samples comparison has been made between the static and dynamic results and these have been compared with recent theoretical predictions. Revue Phys. Appl. 15 (1980) 1399-1408 AOÛT 1980,

First inelastic neutron scattering studies on thin free standing polymer films.
Glass transition studies in free standing polymer films have revealed values of the transition temperature, T(g), which were substantially reduced below the bulk for sufficiently thin films. Here we report on the preparation of two stacks of free standing polystyrene films: 70 films with a thickness of h approximately 107 nm and 140 films with h approximately 55 nm with equivalent total sample ...
متن کاملA minicomputer-automated array spectrometer for liquid-chromatographic detection of metabolites.
A third-generation multiwavelength array spectrometer was developed as a detector for the high-resolution liquid-chromatographic characterization of metabolites. Components include a PDP-8/e minicomputer, matched pair of linear photodiode arrays, holographically-ruled gratings, fiber optics, flow cells, and high intensity xenon light source. The wavelength range is 256 nm differential with 1-nm...
متن کاملIncorporation of a differential refractometer into a laser light-scattering spectrometer
A new differential refractometer, which mainly consists of a laser light source, a position-sensitive detector, and a temperature-controlled refractometer cuvette has recently been developed. In comparison with a conventional differential refractometer, it has a different optical design so that the effect of laser beam drift can be greatly reduced. In our design, a very small pinhole is illumin...

Nanoparticles of coordination polymer [Co2(pydc)2(H2O)6]n.2n H2O [H2pydc = pyridine-2,5-dicarboxylic acid] have been synthesized by sonochemical method and characterized by elemental analysis, infrared spectroscopy, powder X-ray diffraction, scanning electron microscopy, DLS particle size analysis and TGA/DTA. The structure of single crystalline coordination polymer developed from nanosized coo...
متن کاملControlled Antibiotic Delivery by Gelatin Nanospheres: Optimization, Characterization and Antibacterial Evaluation
The present work focuses on preparation and characterization of erythromycin loaded gelatin nanoparticles through nanoprecipitation method. The procedure consists of the addition of the aqueous gelatin solution to the non-solvent phase containing Lutherol F127. Three different measures of cross-linker and polymer concentration were also examined, and the optimum concentration was found. The mor...
