A novel approach to provide, thermally sensitive neutral solutions based on chitosan/polyol salt combinations is described. These formulations possess a physiological pH and can be held liquid below room temperature for encapsulating living cells and therapeutic proteins; they form monolithic gels at body temperature. When injected in vivo the liquid formulations turn into gel implants in situ....

microwave energy has potential for the efficient heating of minerals. minerals or materials, which couple to microwave energy are called dielectrics and many valuable minerals are found to be dielectric. the mineral ilmenite is one which shows good dielectric heating characteristics. in this paper, the effect of microwave heat energy on the partial reduction of oxidized ilmenite oxidized in ...

background and objectives:rapid processing of histopathological specimens and decreased turnaround time is important to fulfill the needs of clinicians treating sick patients, so the present study was conducted to compare the time taken and quality of sections in processing of prostatic tissue by rapid microwave and conventional techniques using morphometry.methods: four to five mm thick paired...

in this study, green pepper was dried by a laboratory scale microwave-convective dryer. the effects of microwave power on drying rate, effective moisture diffusivity, and energy consumption of green pepper were studied at four different microwave powers of 180, 360, 540, and 720w. the drying data were fitted to the four thin-layer drying models. the moisture reduction of the green pepper sample...

The liquefaction of crop residues in the presence of ethylene glycol, ethylene carbonate, or polyethylene glycol using sulfuric acid as a catalyst was studied. For all experiments, the liquefaction was conducted at 160°C and atmospheric pressure. The mass ratio of feedstock to liquefaction solvents used in all the experiments was 30:100. The results show that the acid catalyzed liquefaction pro...

Polyol concentrations were determined by selected-ion monitoring in 10 sample sets taken before dialysis and hourly for 4 h during dialysis. Predialysis concentrations (mumol/L) exceeding the upper limit of normal (mean + 2 SD; n = 33) were found for erythritol (25.4-59.0), threitol (11.5-46.7), and arabinitol (21.0-49.3) in all 10 cases; mannitol (2.7-62.0) in nine cases; and xylitol (0.7-1.3)...

an increase in the red cell's normal substrate, glucose, can produce changes in red cell metabolism.

We report the effect of a polyol-mediated annealing on nickel ferrite nanoparticles. By combining X-ray fluorescence spectroscopy, diffraction, and 57 Fe Mössbauer spectrometry, we showed that whereas as-prepared nanoparticles (NFO) are stoichiometric, annealed ones (a-NFO) not, since Ni 0 -based crystals precipitate. Nickel depletion from spinel lattice reduction in polyol solvent accompanied ...
