As a metal-free photocatalyst, the photocatalytic activity of graphitic carbon nitride (g-C3N4) remains restricted due to an insufficient visible-light absorption capacity, the rapid recombination of photoinduced carriers, and low surface area. Consequently, P-doped g-C3N4 (PCN) was successfully prepared via a single -step thermal polymerization technique using phytic acid biomass and urea, which exhibited remarkable photocatalytic activity for the degradation of indometacin (IDM). The IDM degradation rate was 7.1 times greater than that of pristine g-C3N4 (CN). Furthermore, Ag2WO4 was loaded onto the surface of the PCN, which formed a Z-scheme heterostructure that promoted the separation of photogenerated carriers. According to analyses of the chemical binding states of PCN, P atoms replaced carbon atoms in the CN framework. According to electron localization function analysis, the low ELF values of P-N facilitated the transfer of photoelectrons. The results of active species scavenging experiments confirmed that superoxide radicals were the primary active species in the photocatalytic degradation system. Finally, the photocatalytic degradation pathways of IDM were predicted through the identification of by-products and IDM reaction sites. This paper examines the effects of the slope on the burning and spread process of JP-4 continuous spill fires. Spill fires experiments were conducted on surfaces with different slope angles (0˚-3˚) in a rectangular trench (0.8m×6m). The spread and burning behaviors including the spread process, burning rate and flame height are recorded and analyzed. The results indicate that the whole spread process can be divided, based on the burning area variations with time, into four phases 1) burning layer spread, 2) shrink process, 3) steady burning, and 4) extinguishment. The results also show that a large slope can increase the spread rate and as a result shorten the duration of the burning layer spread and shrink process phases. In addition, it is found that the slope has a more significant effect on the maximum spread area than the steady burning area. The steady burning rate decreases with increasing slope and the ratio of the steady burning rate of a spill fire and that of the corresponding pool fire is nearly constant. The flame height of continuous spill fires is also well predicted by an empirical model with a dimensionless heat release rate and equivalent pool diameter. The experimental data presented in the work will provide a basis for further studies of liquid fuel spill fire on an inclined surface. Crown V.

Experimental result showed that long-term exposure to 10 μg/L NOR induced negligible effects on phosphorus removal. The presence of 100 μg/L NOR slightly decreased phosphorus removal efficiency to 94.41 ± 1.59 %. However, when NOR level further increased to 500 μg/L, phosphorus removal efficiency was significantly decreased from 97.96 ± 0.8 5% (control) to 82.33 ± 3.07 %. The mechanism study revealed that the presence of 500 μg/L NOR inhibited anaerobic phosphorus release and acetate uptake as well as aerobic phosphorus uptake during long-term exposure. It was also found that 500 μg/L NOR exposure suppressed the activity of key enzymes related to phosphorus removal but promoted the transformations of intracellular polyhydroxyalkanoate and glycogen. Microbial analysis revealed that that the presence of 500 μg/L NOR reduced the abundances of polyphosphate accumulating organisms but increased glycogen accumulating organisms, as compared the control. The central nervous system is a potential target for Al2O3 nanoparticles (Nano-Al2O3). Here, we investigated the effects of intranasal instillation of Nano-Al2O3 on the distribution and damage in crucial functional sub-brain regions of rats. In vivo results show that Nano-Al2O3 was translocated into the brain via the olfactory nerve pathway. Nano-Al2O3 accumulated in the hippocampus, olfactory bulb, cerebral cortex, and striatum, causing ultrastructural changes, oxidative damage, inflammatory responses, and histopathological damage in sub-brain regions. As indicated by in vitro studies, cell viability decreased with the addition of Nano-Al2O3, which increased the levels of lactate dehydrogenase and oxidative stress. Nano-Al2O3 also impaired mitochondrial function, disturbed the cell cycle and induced apoptosis.

Therefore, oxidative stress, mitochondrial dysfunction, and p53-related pathways might be important in the process of dopaminergic neurotoxicity induced by Nano-Al2O3. The current study establishes a striatum damage model and identifies molecular biomarkers of dopaminergic neuron damage induced by Nano-Al2O3. In brief, our study demonstrates that Nano-Al2O3 exposure can be a risk factor for neurodegenerative diseases and may negatively impact the hippocampus, striatum, and dopaminergic neurons. The porous carbon materials formed from biomass precursors are promising candidates for adsorbing organic vapor pollutants. However, these materials have insufficient pores, which hinder their accessibility to adsorbates. This study develops an ultrahigh-surface-area porous carbon adsorbent with interlacing micro-mesoporous structures through Trichoderma viride decomposition. An orthogonal experiment is conducted, and the most suitable conditions for fabricating porous carbon with an ultrahigh SBET of 3714 m2.g-1 and a hierarchical porous structure are identified. This work achieves one of the highest specific surface areas of biomass carbons among recent studies. T. viride corrodes the internal and external microstructures of rice husks, and regulates the lignin, cellulose, and hemicellulose contents, which improve the efficiency of carbonization and chemical activation. The carbonaceous materials with microbial pretreatment exhibit better toluene adsorption performances (100 ppm 708 mg.g-1), adsorption rates, and cyclic utilization than those without pretreatment (100 pm 538 mg.
