Background: Disruption of tight junctions is associated with various inflammatory diseases, including inflammatory bowel syndrome. Tight junctions form a protective barrier throughout the intestinal tract that is central to health. Glyphosate is known to inhibit tight junction function. The aim of this study was to assess the effect of a soil-derived, lignite extract dietary supplement in prote...
Abundant and cheap lignite is regarded as inferior fuel due to its disadvantages such low heat high moisture. In order realize the value clean, non-fuel utilization of lignite, we used precursor prepare high-quality synthetic graphite through graphitization treatment using temperature–high pressure (HTHP) method, afterwards characterized samples by XRD, Raman, FTIR, SEM-EDS, HRTEM, systematical...
For the Polish power industry, basic fuel is hard coal and lignite, which contains significant amounts of mercury. Current emission standards in European Union (IED directive near future BAT conclusions) create conditions for investment flue gas cleaning installations coal-fired plants. During combustion coal, mainly metallic mercury (Hg 0 ) produced, difficult to remove from dedusting (electro...
Montan wax origins from ancient plant which leads a long and slow way towards becoming lignite thousands of years ago, their composition is very complex. Crude montan wax is obtained after organic solvent extraction from lignite, then deresined wax is acquired by cooling the extracted solvent toluene, last refined wax called S wax could be made after a series oxidation process, which can be use...
A large number of filter materials, organic and inorganic, for removal of heavy metals in mine drainage have been reviewed. Bark, chitin, chitosan, commercial ion exchangers, dairy manure compost, lignite, peat, rice husks, vegetal compost, and yeast are examples of organic materials, while bio-carbons, calcareous shale, dolomite, fly ash, limestone, olivine, steel slag materials and zeolites a...
We selected, as the objects of our research, lignite from the Beizao Mine, gas coal from the Caiyuan Mine, coking coal from the Xiqu Mine, and anthracite from the Guhanshan Mine. We used the mercury intrusion method and the low-temperature liquid nitrogen adsorption method to analyze the structure and shape of the coal pores and calculated the fractal dimensions of different aperture segments i...
The adsorptive capacity of powdered activated carbon (PAC) is related to the size of the target adsorbate compared with the quantity of pores with sufficient pore diameter into which the adsorbate may diffuse (i.e., the effective internal surface area). The adsorptive capacity of PACs are commonly characterized using aqueous-phase indices such as iodine (I2), methylene blue (MB), p-nitrophenol ...
