Properties that describe how a substance changes into a completely different substance are called chemical properties. 11.相变是一种物理性质,并且物质存在四种相:固相、液相、气相和等离子体。 Phase transformation is a physical property of matter, and matter can exist in four phase: solid, liquid, gas...

Vickers hardness is a fundamental property that is essential to describe the mechanical behavior of mineral, various semi-empirical relations have been proposed to estimate hardness using the elastic moduli. Vickers hardness is predicted using two theoretical models of hardness: ...
In recent years, there has been considerable progress in determining the soil properties that influence the structure of the soil microbiome. By contrast, the effects of microorganisms on their soil habitat have received less attention with most previous
We find that the vacuum fluctuation of the Delta-isobar is very important to the properties of Delta-resonance nuclear matter, even if at low temperature. We calculate the pressure density both in quantum hadrodynamics model and in thermostatistical mechanics, and we find that they are consistent...
It appears that their size can be used as a tool to describe the spatial distribution of electronic excitations induced by the relaxation process after the high-energy excitation. Finally, potentiality to grow transparent bulk materials based on small Nps agglomeration via soft chemistry route is ...
The packing behavior of wet particles is different from that of dry particles, as seen from work on the packing of iron ore fines or coal particles (Yu et al., 1995). Results showed that there were many forms of water between the particles (Karthikeyan et al., 2009), e.g. crystal ...
The hygroscopic property of particulate matter (PM) influencing light scattering and absorption is vital for determining visibility and accurate sensing of PM using a low-cost sensor. In this study, we examined the hygroscopic properties of coarse PM (CPM) and fine PM (FPM; PM2.5) and the eff...
In the context of the last 35 years of debates in the field of cuprates, each new demonstration that textbook FL formulas can be used to describe a key property of these materials marks essential progress. Here, we have shown that these formulas are perfectly adequate to calculate transport ...
Results indicated that both the Young's modulus and hardness decreased significantly with an increase of moisture content. A rheology model was developed to describe the nanoindentation behaviors of wood cell walls at different moisture contents. Five parameters were extracted from Burger's model, and...
