Abstract Poplar (Populus nigra) flash pyrolysis has been performed at the IK4-Ikerlan 25 kg h-1 pilot plant equipped with a conical spouted bed reactor. Gas, bio-oil and char yields and properties have been studied in the 425-525C range. This reactor has been proven to be especially suitable for this process as high bio-oil yields have been obtained, with the maximum being 69 wt.% at 455C. The bio-oil has been collected in two fractions: the lighter one, which accounts for 85 wt.% of the bio-oil, has a high water content and is composed mainly of acids and ketones, whereas the heavier fraction has a lower water content and is rich in phenols. These fractions are miscible, obtaining a bio-oil with a water content lower than 25 wt.% and a higher heating value in the 16-18 MJ kg-1 range.

High stability of low-kappa value in a broad temperature region is a critical property for low dielectric constant polymer materials especially when they are served in some harsh conditions. However, most polymer dielectrics always exhibit a significant variation in dielectric property at around Tg or sub-Tg due to the local segment or chains motion, thus, low-kappa polymer dielectrics are limited to a relatively narrow working temperature region. Herein, we described a series of novel crosslinked polyimide (PI) thermosets by blending a reactive Cardo-containing diluent into the PI oligomer, the dielectric constants of which were greatly reduced from 3.4 to 2.5 and were surprisingly stable over a temperature region of -150-250 C. Meanwhile, the cured blended thermosets exhibited a 32?139 C increase in Tg compared to the pristine PI. Detailed analyses have illustrated that the significantly reduced kappa value, highly stable dielectric property and superior stability of these blended samples are originated from the synergistic effects of the large free-volume of Cardo-containing diluent, looser molecule packing resulted from the TR reaction and the highly crosslinked network. This desirable combination of facile processability, attractive dielectric behavior and excellent thermal stability makes them potential utilization in aerospace, microelectronic industries and other harsh environment applications.

The photo-Fenton process is intensified for degradation of carbofuran by using a tubular microreactor coiled around a florescent light. The microreactor attained 7.5 times faster degradation rate compared to a batch reactor operated under a LED light. At the initial Fe2+ concentration of 0.25 mM, the degradation rates in the batch reactor were fast at first, subsequently became slow, and afterward gradually increased with time regardless of light intensity. In the microreactor, the degradation rates appeared to decrease similarly to the first-order reaction despite the same initial Fe2+ concentration. A proposed kinetic model well fitted the results of both batch and microreactors by modeling that Fe3+ is photoreduced in a complex in equilibrium with Fe3+ and intermediates with carboxyl group decomposed from carbofuran.

trans-3,4-Dimethyl-4-(3-carboxamidophenyl)piperidines constitute a novel class of mu opioid receptor antagonists. The CONH2 group was found to be an effective isostere of the phenolic OH moiety. Structure-activity relationships at the piperidine nitrogen position led to the identification of several ligands displaying high affinity toward the cloned human mu opioid receptors, good selectivity mu/delta, mu/kappa, and potent in vitro antagonist activity.
