“…The plot of the variety Jaya, presented in Fig. 1, shows the linearity similar to that given by the results of the absorption study (Bandyopadhyay & Roy, 1976). It suggests that the diffusion equation (2) is applicable in the case of moisture desorption also.…”

“…2). Two features were noted: Firstly, the Arrhenius line, instead of showing a break as observed in the result of absorption study (Bandyopadhyay & Roy, 1976, 1978 showed linearity for the whole temperature range, and secondly, the value of activation energy, 7600 cal/mole, is almost identical with that obtained in the lower temperture region of soaking for the Jaya variety -7654 cal/mole (Bandyopadhyay & Roy, 1976). The result evidently indicates that the activation energy of the diffusional processboth absorption and desorption of + lo3, OK-' moisture within the grainis independent of the direction of migration of moisture.…”

“…For preliminary work, one particular variety of paddy, (e.g. Jaya) was selected from the varieties studied earlier and soaked according to the method already described (Bandyopadhyay & Roy, 1976). The time and temperature of soaking for the variety were 7 hr and 65°C and moisture content of the soaked grains was around 0.5 g/g dry basis.…”

“…The authors have shown in earlier studies (Bandyopadhyay & Roy, 1976, 1978) that absorption of water by paddy grains during parboiling at elevated temperatures in a batch soaking operation can be described by a semi-empirical diffusion equation. The validity of the equation was proved under some limiting conditions with the soaking data of a large number of paddy varieties (Bandyopadhyay & Roy, 1978). It was felt that investigations should be further carried out to obtain data on moisture in soaked paddy grains under opposite conditions (grains fully exposed to air at a constant temperature and humidity) and to elucidate the process of drying of parboiled paddy.…”

The desorption of water from a thin layer of hot-soaked parboiled paddy grains was studied under constant drying conditions within a temperature range 40-70°C and at a constant relative humidity of 60%. The data of one variety of paddy were correlated with the help of the semi-empirical diffusion equation which was confirmed with the soaking data of a large number of paddy varieties by the authors. The results indicated that activation energy of the diffusional process (7654 cal/mole for moisture absorption and 7600 cal/mole for the desorption process) is independent of the direction of changes in the moisture level.

This article reveals the potential use of a macroporous 3D poly(ε‐caprolactone)‐zinc montmorillonite (PCL‐ZnMMT) composite scaffold as a bone tissue engineering template. The zinc‐incorporated porous scaffold was prepared by combining solvent casting and particulate leaching technique. Later, PCL‐ZnMMT composite scaffolds were characterized for their physicochemical, mechanical and in vitro biological properties. Human adipose stem cells (hASCs) were utilized for in vitro cell culture studies. Cell viability and proliferation of cell‐scaffold constructs were investigated using the Alamar Blue and Live/Dead‐staining assays. The osteogenic differentiation potential of hASCs on PCL‐ZnMMT scaffolds was evaluated by the alkaline phosphatase assay; Scanning electron microscopy (SEM) was used to visualize mineral accumulation. X‐ray diffraction results indicate that the incorporation of MMT into polymer matrix. Thermal gravimetric analysis showed that the presence of clay improves thermal stability of polymeric matrix. ICP findings showed that Zn ion concentration in the cell culture medium was at a sustainable range up to 7 days. SEM micrographs reveal that scaffold had a highly porous morphology and also the infiltration of cells into the porous structure. In vitro studies showed that the incorporation of Zn into the PCL‐MMT system stimulated the in vitro proliferation and osteogenic differentiation of hASCs. Findings indicate that PCL‐ZnMMT scaffold composite may be a promising biomaterial for tissue engineering applications. POLYM. COMPOS., 39:E601–E608, 2018. © 2018 Society of Plastics Engineers

Al~traet. Hot-wall technique greatly improves the quality of zinc and cadmium films deposited on glass substrate. At substrate temperature the growth of such films is well ordered, showing highly preferred orientation along c-axis. However, if the substrate temperature is increased beyond certain limit, we get poLycrystalline growth of the films. This shows that the growth of zinc and cadmium films on glass substrate strongly depends on the substrate temperature. Keywords. X-ray diffraction; epitaxial growth; hot-wall technique; zinc films; cadmium films.
