in this study, copper chromite (cucr2o4) nanoparticles was prepared by inverse co-precipitation method. in this method, cupric nitrate trihydrate, (cu (no3)2.3h2o) and chromium nitrate nonahydrate, (cr (no3) 3.9h2o) with a mole ratio of 1:2 were used. characterization of cucr2o4 nanoparticles was performed by fourier transform infrared spectroscopy (ft-ir), raman spectroscopy, x-ray diffraction...

When an aluminum alloy is solution annealed and afterwards cooled too slowly, an exothermal precipitation reaction occurs. With increasing cooling rate, the precipitation heat decreases. Since the precipitation reaction is relatively fast, a fast cooling rate on the differential scanning calorimeter (DSC) is essential to obtain the critical cooling rate which is the minimum cooling rate at whic...

the major hydraulic phase in all the calcium aluminate cements including ciment fondue is ca (caal2o4). once hydrated, it starts to form the hexagonal crystals of cah10 and c2ah8 that depending on the time and temperature of hydration convert to the cubic crystals of c3ah6 and ah3. the nature, sequence, crystallinity and microstructure of hydrated phases of commercial refractory calcium alumina...

The hydration of actin was studied by differential scanning calorimetry between -30 degrees C and 30 degrees C and by thermogravimetric analysis. The differential scanning calorimetry provided the freezable water content of G- and F-actin as a function of concentration, and the thermogravimetric analysis measured the total water content. The difference between the two yielded the nonfreezable w...

Differential scanning calorimetry (DSC) is used to evaluate the thermal stability and reversibility after heat treatment of transitions associated with various cellular components of Escherichia coli and Lactobacillus plantarum. The reversibility and the change in the thermal stability of individual transitions are evaluated by a second temperature scan after preheating in the DSC to various te...

The influence of nanoconfinement on the crystallization behavior of acetaminophen, a polymorphic drug occurring in three different crystalline forms, is investigated. Differential scanning calorimetry (DSC) and wide angle X-ray scattering (WAXS) data for a series of controlled porous glasses (CPGs) filled with acetaminophen are presented. The results show clearly that (i) the usually inaccessib...

In this paper I relate the loss of CFU following a life-threatening treatment to the inactivation of critical components. Equations are used to calculate the loss of CFU following isothermal and temperature-scanning treatments, and the results are discussed in relation to differential scanning calorimetry of bacteria.

The silver salts of fatty acids were studied as precursors for the preparation of colloidal dispersions of silver nanoparticles and UHMWPE (ultra-high-molecular-weight polyethylene) composite with silver nanoparticles, as well as the composition, the spectra and SEM (scanning electron microscopy) results. keywords: Silver laurate, silver palmitate, ascorbic acid, differential scanning spectrosc...

In this paper, differential phase imaging (DPC) with transmitted light is implemented by adding a suitable detection system to a standard commercially available scanning confocal microscope. DPC, a long-established method in scanning optical microscopy, depends on detecting the intensity difference between opposite halves or quadrants of a split photodiode detector placed in an aperture plane. ...
