- Sorbents for desulphurisation of biogas based on iron compounds. Part 2 - Granulates and desulphurizing masses
In addition to fine natural and modified turf ores, granular desulphurizing masses containing various additives are used as hydrogen sulfide sorbents. Part 2 of the work reviews selected selected sorbents containing iron, e.g. artificially synthesized hydrated iron oxides, iron (III) hydroxide, halloysite sorbent and some granulated desulphurizing masses used in Poland for biogas purification. - Between silence and silence ...
Grzegorz Turnau can be liked. My neighbor especially values him, values his music and arrangements. He listens carefully to his texts. He cannot agree with one stanza. It is not true - he says - that "between silence and silence things sway". They sway in constant noise. There is no more silence in Poland. She died. In fact, where you put your ear, you can hear noise, noise, clatter, crackling and vibrations. Not only in factories, on the streets, in homes or stadiums, but also in libraries and operating rooms. Crumbs of silence are found only in the secluded chapel or in the volume of poems by Wisława Szymborska. Noise is a scourge - annoying and, unfortunately, neglected. Healers, of course, recommend us semolina, walks along health paths, freshly brewed herbs, sometimes a water filter [...] - Solar farms - review
Ryszard Tytko, Photovoltaics. Handbook for students, pupils, installers, investors, 1st Edition, Publishing House and Printing House of the Slovak Society in Poland, Krakow 2019, p. 456. For thousands of years our planet has been using sunlight, although their source is located 150 million kilometers from Earth. According to the calculations of the scientists, within half a year as much solar energy reaches the Earth as all coal, oil, gas and uranium deposits together. The rapid increase in energy demand to improve people's quality of life is one of the reasons for the development of industry that began in the 18th century. However, by the mid-twentieth century, only a few considered the long-term consequences of rapid development on a global scale. The perceptible pollution of the atmosphere, soil and water, the limitation of the availability of drinking water resources and the gradual depletion of natural resources, especially the emergence of new categories of civilization diseases, have forced the international community to look for alternative development paths. - Technology curiosities from around the world
Solar perovskite In the search for environmentally friendly energy technologies, scientists are exploring a variety of materials and their combinations. One of the often considered solutions is the use of perovskite, which is cheap to manufacture and can be used in solar cells. Interest in perovskite cells has been going on for quite some time, because this material has a high rate of solar energy conversion into electricity. In addition, in recent years its efficiency in cells has also been significantly increased. There is a problem, however. Due to the structure of the perovskite, it is very difficult to achieve consistent quality of the cell layers produced, without holes or other defects affecting their efficiency. Fortunately, we have managed to increase the efficiency of the cells once again by adding carbon nanotubes to them. Here, another problem was encountered, associated with the merging of perovskite with carbon, which is not the most durable. The solution may be brought by the research of scientists from Tokyo, who used not pure nanotubes for the production of cells, but containing oxygen surfaces [...] - A rain of money
Ratified by Poland, the AGN Convention (European Shipping Agreement) provides for spending huge amounts of money to navigate Polish rivers. The ideas of the shipping lobby ignore the fact that Poland has no conditions to get even a little closer to the realities known from the Rhine or Danube. Inland water transport is not only ecologically worse than rail, but - above all - there is no chance in Poland of significant participation in transport work. Spilling money from the taxpayer's pocket for investments that (allegedly) are to be used not only for transport, but also for energy and flood protection, is not justified.
