Przebieg i analiza produktów wolnej i szybkiej pirolizy biomasy
Publikacjagraniczone zasoby paliw kopalnych zmuszają do refleksji na temat przyszłości energetyki. Wykorzystywanie do celów energetycznych jedynie, lub w znacznej większości paliw kopalnych nie daje poczucia bezpieczeństwa z powodu braku realnej alternatywy, dlatego ważnym jest poszukiwanie nowych źródeł energii - zielonej, odnawialnej, bezpiecznej. Taką alternatywą może być wykorzystanie drewna po odpowiedniej obróbce - w przypadku poniższej...

Influence of microstructure on properties of 18Cr-10Ni-Ti stainless steel products.
PublikacjaBadano wpływ mikrostruktury na właściwości mechaniczne i odporność korozyjną wyrobów ze stali austenitycznej 18Cr-10Ni-Ti po przesycaniu z temperatury 1050 C. Wykazano, że węgliki TiC w ziarnach i na granicach ziaren/bliźniaków powodują znaczne obniżenie wydłużenia stali. Węgliki TiC na granicach ziaren/bliźniaków obniżają odporność na korozję międzykrystaliczną i sprzyjają powstawaniu uszkodzeń korozyjnych podczas hutniczej operacji...

Receptor for advanced glycation end‐products: Biological significance and imaging applications
PublikacjaThe receptor for advanced glycation end-products (RAGE or AGER) is a transmembrane, immunoglobulin-like receptor that, due to its multiple isoform structures, binds to a diverse range of endo- and exogenous ligands. RAGE activation caused by the ligand binding initiates a cascade of complex pathways associated with producing free radicals, such as reactive nitric oxide and oxygen species, cell proliferation, and immunoinflammatory...

Hydrazinolysis Products of Selected Sugar Lactones—Crystal Structure and Microbiological Activity
PublikacjaCommercially available lactones, as well as those synthesized by us, turned out to be good substrates for the synthesis of sugar hydrazides. The exception was L-ascorbic acid, whose hydrazinolysis led to the formation of a hydrazinium salt, not the hydrazide as expected. The structure of all compounds was confirmed by NMR and X-ray analyses. The lower durability of hydrazinium L-ascorbate was additionally confirmed by thermogravimetric...

iPP/HDPE blends compatibilized by a polyester: An unconventional concept to valuable products
PublikacjaPolyolefins are the most widely used plastics accounting for a large fraction of the polymer waste stream. Although reusing polyolefins seems to be a logical choice, their recycling level remains disappointingly low. This is mainly due to the lack of large-scale availability of efficient and inexpensive compatibilizers for mixed polyolefin waste, typically consisting of high-density polyethylene (HDPE) and isotactic polypropylene...
