We report the growth of well-crystallized and epitaxially textured Pr0.6Ca0.4MnO3 thin films on SrTiO3 substrates by pulsed laser deposition at considerably low substrate temperatures, as low as 450 ◦C, without high-temperature post-annealing treatments. Although a strong ferromagnetic interaction as well as a large irreversible metamagnetic transition with a training effect have been observed ...

To test the hypothesized inhibition of high-latitude marine bacteria living at lower temperatures when organic matter is scarce, the effects of temperature and organic substrate concentration on pelagic microbial heterotrophy were investigated in the perennially cold surface waters of a summertime arctic polynya. Utilization (incorporation plus respiration) of radiolabeled amino acids was measu...

background and objective: glucoamylase is a potent starch degrading enzyme whose cheap production has been an area of research. its production by aspergillus niger in solid-state fermentation was studied using dried garden pea peel as a substrate, which enormously reduced the production cost. the current study intended to produce glucoamylase by a cost-effective strategy and exhaustively charac...

Body temperatures of Blanus cinereus recorded in the field in central Spain were positively correlated with corresponding substrate and air temperatures. Mean body temperature was 1.2°C higher than corresponding mean substrate temperature. Mean body temperature varied with time of day. Presence under stones during daylight hours was bimodal and seasonal variation was observed in body temperature.

We report on the molecular beam epitaxy growth of Au-assisted GaAs p-type-doped NW arrays on the n-type GaAs(111)B substrate and their photovoltaic properties. The samples are grown at different substrate temperature within the range from 520 to 580 °C. It is shown that the dependence of conversion efficiency on the substrate temperature has a maximum at the substrate temperature of 550 °C. For...

the activity of phospholipase c in crude enzymatic preparation of melia azadiracht seeds (neem seeds) was studied by the use of lecithin as a substrate in aqueous medium. the enzyme activity was found optimum at ph 2.5 and temperature 35?c. the phospholipase c was found heat labile, being inactivated 88% within 10 minutes at 90°c

Nickel oxide (NiO) semiconductors thin films were prepared by e-beam evaporation technique at different substrate temperatures ranging from room temperature to 400 C on glass substrate. Glancing incident X-ray diffraction depict that with the increases in substrate temperature the preferred orientation changes from (111) to (200) direction. Atomic force microscopy was used to investigate the su...
