Abnormalni rast zrna u toku medjužarenja u Al-Mg legurama / Abnormal grain growth during intermediate annealing of Al-Mg alloys
(Beograd : Srpsko hemijsko društvo = Serbian Chemical Society, 2022)
U završnoj fazi prerade Al-Mg legura, pojava abnormalnih zrna (AGG) u strukturi je
nepoželjna, jer dovodi do pogoršanja mehaničkih osobina. Medjutim, postoji veliki interes
za proučavanjem uticaja AGG, koja nastaju u ...
Modulation of Functional Characteristics of Mesenchymal Stromal Cells by Acellular Preparation of Porcine Hemoglobin
(MDPI, 2022)
Exploring the potential usage of the acellular preparation of porcine hemoglobin (PHb) isolated from slaughterhouse blood as a cell culture media component, we have tested its effects on the functional characteristics of ...
