say 25 °C. If we slowly push in the plunger while keeping temperature constant, the gas in the syringe is compressed into a smaller volume and its pressure increases; if we pull out the plunger, the volume increases and the pressure decreases. This example...
In subject area:Chemistry Glass Transition Temperature refers to the temperature at which a material transitions from a rigid, glassy state to a more flexible, rubbery state. It can vary depending on factors such as the grade of the material, the curing process, and moisture content. ...
Rapid synthesis of zeolitic imidazolate framework-8 (ZIF-8) nanocrystals in an aqueous system We report here the first example of ZIF materials synthesized in aqueous solution. The synthesis was performed at room temperature and typically took sever... Y Pan,Y Liu,G Zeng,... - 《Chemical ...
Whilst some rectal temperature variations may be tracking whole-body changes, in other circumstances (Fig. 4), a temperature elevation may be explained by a different mechanism. For example, combined exercise and heat stresses may induce a powerful reduction in visceral blood flow, and in this ci...
Seawater chemistry A summary of seawater chemistry parameters is presented in Table 1. Temperature and pH were significantly different among treatments (F1:106 = 169.98, p < 0.001; F1:106 = 1412.22, p < 0.001, respectively), as expected for the different temperature and pH ...

Notwithstanding this correlation, melt chemistry and upper mantle shear-wave velocity can also be influenced by changes in lithospheric thickness, by the composition of the mantle source region, and by depth of the base of the melt column, which is controlled by a combination of mantle temperature...
Richard W. Roberts, in Comprehensive Natural Products Chemistry, 1999 (i) Thermal melting temperature In addition to the thermodynamic properties described above, we also consider Tm, the thermal melting temperature. The Tm, which is defined as the temperature at which one half of a complex is ...
Since the discovery of fullerenes in 1985 [1], there has been substantial progress in employing these molecules as one of the most important building blocks of nanostructures. Due to their unique chemistry and their technological applications, particularly in electronics, nanotechnology, material science...
