We have measured the specific heat capacity c of C /C between 110 and 310 K and its compressibility 魏 up to 1.1 GPa (11 kbar) at 293 K, a range in t and p which overlaps reported ranges of stability of both the rotationally disordered h... A Lundin,B Sundqvist,P Skoglund,......
We report systematic measurements ofC v and (∂P/∂T) v in solid hydrogen below 1 K and for orthohydrogen molar concentrations 0.58≥X ortho≥0.20. This is the temperature and concentration range associated with a proposed quadrupolar glass phase. The results show no overtly glassy properties...
To avoid this conduction error, the probe should be a poor heat conductor. In measuring surface temperatures, the probe should not have an insulating effect, as this will change the temperature in the measuring point. Also, the radiation exchange between the probe and surrounding surfaces can be...
Furthermore, the correlation between lipoprotein composition and fluidity was calculated in order to discuss the possible factors responsible for fluidity change. Seemingly, lipoprotein fluidity was correlated with cholesterol content (especially LDL and HDL), triglyceride and cholesterol/phospholipid ratio ...
Consequently, the molar TIMP/MMP ratio was 40 in the non-pregnant state and 0.2 at term. The MMP-2 and TIMP-1 concentrations were alike in the CMP-dists and the whole CMPs. MMP-8, MMP-9, and IL-8 were mainly found in the distal CMP compartment. MMP-8 and MMP-9 concentrations ...
It relates the two specific heat capacities to the universal gas constant (R). What is the difference between Cp=Cv+R and Cp-Cv=R? The equations Cp=Cv+R and Cp-Cv=R are mathematically equivalent and both represent the Mayer's relation. The only difference is that Cp=Cv+...
A method and an apparatus for the 24 hours a day conversion of the high difference of temperatures between two working mediums accumulating the Sun-radiation-heat gets concentrated by the parabolical mirror, during light-days, and the co... HY Zagalsky 被引量: 0发表: 2008年 "Radiographic ...
In addition, it was confirmed that a chitosan sample with moderate molar mass (MW ~100,000) is more convenient to control the viscosity of the spinnable solution. In these conditions, nanofibers made of blend PEO/chitosan have average diameters under dried state between 100 and 150 nm [13]...
the SC state of charge (SOC) is considered to avoid supercapacitor improper operations; the fuel cell power output is varied according to the ratio between initial and current SOC, using a proper supercapacitor comparative factor (kSC) that assumes different values for charging and discharging mode...
