Although there are well-established design rules for calamitic nematic materials, it has proven rather more difficult to synthesise bent-core molecules with nematic phases, and especially to control the extent and absolute temperature of the nematic regime.
This insensitivity to temperature makes practical monitoring of nonisothermal reactions much simpler than many fluorescence techniques whose measurable is a function of both extent of reaction and temperature.
A detailed account of the effects of structure, concentration and dispersion of POSS in the matrix, molecular weight of PPO, extent of reaction and temperature on the molecular origin, temperature dependence and spectral characteristics of relaxation processes in POSS/PPO nanocomposites is provided.
The microstructure of foams reveals a homogeneous distribution of cells at high precuring extent and high foaming temperature, while small cells size at high precuring extent and low foaming temperature.
We thus identified three candidate HEMUs: presence/absence (inundation extent), thickness, dynamic pressure, and temperature.
The rate of photoinduced hydrogen production depends strongly on the concentration of the sacrificial agent employed and to a lesser extent on solution pH and temperature.
Scorpions inhabit all terrestrial habitats with the exception of tundra, high-latitude taiga, and some high-elevation mountain tops and their spatial distribution is influenced, to a large extent, by temperature and precipitation [1].
The results showed a statistically significant effect of pH and pulp density – and to a lesser extent temperature and initial Fe(II) concentration – on the rate of bioleaching of Zn.
In this paper, a model is presented for predicting the spatial temperature distribution of a gradient coil, including the location and extent of temperature hot spots.
To the extent possible, inlet flow rate and temperature were held constant during each test.
