We have designed a new magnetic targeting drug carrier Fe3O4-PVA with core of triiron tetroxide (Fe3O4) and shell made polyvinyl alcohol (PVA) to improve the hydrophilicity Fe3O4. With adriamycin hydrochloride as model drug, this study goes on measure performance Fe3O4-PVA. In addition, thermal stability enthalpy decomposition were measured using differential scanning calorimeter non-isothermal...

On 12 August 2015, Tianjin port, City, China, a catastrophic explosion of Ruihai International Logistics Co., Ltd. (Tianjin, China) killed 173 and hurt almost 798 people, accompanying financial loss USD 2 billion. The ignition the first fire due to autocatalytic decomposition nitrocellulose was verified by differential scanning calorimeter (DSC) isothermal tests. A crater with diameter 97 m cre...

In this study, polylactide/urea complexes were successfully prepared by the electrospinning method, then the host urea component was removed to obtain a coalesced poly(L-lactide) (PLLA)/poly(D-lactide) (PDLA) blend. The crystallization behavior of the coalesced PLLA/PDLA blend (c-PLLA/PDLA) was studied by a differential scanning calorimeter (DSC) and Fourier transform infrared (FTIR) spectrosco...

A hybrid calorimeter is described whereby the test specimen may be heated using either hot air and/or microwave radiation. Thus it is possible to study phase transitions of materials under conditions ranging from purely conventional heating to pure microwave heating or mixtures thereof. Measurements using silver iodide showed that its phase change from the low temperature β-phase to the high te...

The correct determination of the energy generated or absorbed in the sample cell of an Isothermal Titration Calorimeter (ITC) requires a thorough analysis of the calorimetric signal. This means the identification and quantification of any thermal effect inherent to the working method. In this work, it is carried out a review on several thermal effects, studied by us in previous work, and which ...

Lithium- and manganese-rich NCM (LMR-NCM) cathode active materials exhibit a pronounced energy inefficiency during charge discharge that results in strong heat generation operation. The implications of such are investigated for large-format lithium-ion batteries. Small laboratory cells generally considered isothermal, but larger cell formats this cannot be neglected. Therefore, the LMR-NCM/grap...

AIMS This study aimed to apply differential scanning calorimetry (DSC) to evaluate the thermal inactivation kinetics of bacteria. METHODS AND RESULTS The apparent enthalpy (DeltaH) of Escherichia coli cells was evaluated by a temperature scan in a DSC after thermal pretreatment in the calorimeter to various temperatures between 56 and 80 degrees C. Conventional semilogarithmic survival curve ...

Using a high sensitivity differential scanning calorimeter in isothermal mode, we directly measured heat production in eukaryotic protists from 5 phyla spanning over 5 orders of magnitude in carbon biomass and 8 orders of magnitude in cell volume. Our results reveal that metabolic heat production normalized to cell mass is virtually constant in these organisms, with a median of 0.037 pW pg C(-1...
