Negative Pressure Drying (NPD) is new alternative technique for Low Rank Coal (LRC) drying. In this work, the dehydration, thermal fragmentation and volumetric shrinkage behaviors of LRC under a sustained environment of 423 K and 20 kPa were studied. The correlations of these behaviors were analysed, and the mechanism of …

In an effort to optimize the experimental procedure the influence of time was evaluated. It was found that most of the fragmentation occurred within 60. min and so all further investigations were limited to a 60 min duration.. The shortened method takes between 3 and 4 h per experiment if cooling and sample work-up are included. 3.2.

Experimental design used to quantify the effects of habitat fragmentation (manipulated through the length of corridors) on temperature-dependent habitat choice at emigration (i.e. stay or leave) and immigration (i.e. where to settle). Six replicates per genotype for each corridor length and central temperature were performed.

The different ionization behaviors enable the differentiation of MNPs with different molecular weights. Notably, we find that a simple thermal pretreatment at 380 °C can facilitate the fragmentation of PS and significantly enhances the intensities of fingerprint peaks in low-mass regions, yielding a detection limit of 25 ng for PS MNPs.
