Samorządy i nauka
Publicationinansowanie nauki w Polsce powinno dążyć do modelu, w którym są trzy źródła funduszy dla nauki: budżet centralny, budżety samorządów terytorialnych oraz przedsiębiorców. Obecnie zwłaszcza trzecie ze źródeł jest relatywnie słabo zaangażowane w rozwój nauki, być może jest to związane częściowo ze zbytnią dominacją budżetu centralnego w finansowaniu naszej nauki. Z kolei dla samorządów wojewódzkich inwestycje w uczelnie powinny być...

Complementary green analytical procedure index (ComplexGAPI) and software
PublicationIt is not easy to find appropriate tools for the evaluation of the “green”nature of analytical methodologies which involve the use of compounds, materials, or chemicals manufactured prior to the analytical step. Here, we propose a new metric for the evaluation of analytical procedures based on the GAC attributes. The proposed solution expands on the well-known green analytical procedure index by adding additional fields pertaining...

Wykorzystanie technik elektromigracyjnych w procedurach oznaczania amin biogennych w napojach alkoholowych
PublicationTechniki elektromigracyjne są obecnie najszybciej rozwijającymi się na przestrzeni ostatnich lat metodami analitycznymi. Biorąc pod uwagę korzyści wynikające z zastosowania elektroforezy kapilarnej oraz możliwość pominięcie etapu derywatyzaji, który jest bardzo kosztowny i pracochłonny, elektroforeza może być alternatywą w oznaczaniu amin biogennych w próbkach żywności i napojów alkoholowych w stosunku do technik chromatograficznych.
