Pyrolysis behaviors of coal-related model compounds catalyzed by pyrite
Pyrite Catalytic pyrolysis Coal-related model compounds Tetrahydronaphthalene
2023/6/19
The pyrolysis behaviors of coal-related model compounds (bibenzyl and benzyloxybenzene) were investigated on a fixed-bed reactor catalyzed by pyrite (main component is FeS2). The pyrolysis products we...
A novel tissue-engineered 3D tumor model for anti-cancer drug discovery
decellularized porcine lung matrix breast tumor model biocompatibility CARS drug resistance
2023/3/1
Cancer biology and drug discovery are heavily dependent on conventional 2D cell culture systems. However, a 2D culture is significantly limited by its ability to reflect 'true biology' of tumor in viv...
Analysis of atmospheric visibility degradation in early haze based on the nucleation clustering model
Early haze Initial nucleation process Heterogeneous cluster Visible-light absorption

2015/9/28
We consider the model for the distribution of a long homopolymer in a potential field. The typical shape of the polymer depends on the temperature parameter.We show that at a critical value of the tem...
A solvable model for homopolymers and self-similarity near critical point
Gibbs measure homopolymer zero-range potential phase transition glob- ular phase diffusive phase
2015/9/28
We consider a model for the distribution of a long homopolymer with an at- tractive zero-range potential at the origin in R3 (polymer pinning and de-pinning). The distribution can be obtained as a lim...
