New insights into the mechanism of Schiff base synthesis from aromatic amines in the absence of acid catalyst or polar solvents [PDF]
, 2020 Extensive computational studies of the imine synthesis from amines and aldehydes in water have shown that the large-scale structure of water is needed to afford appropriate charge delocalization and enable sufficient transition state stabilization. These

Detection of human neutrophil elastase (HNE) on wound dressings as marker of inflammation [PDF]
, 2017 Chronic wound fluids have elevated concentration of human neutrophil elastase (HNE) which can be used as inflammation/infection marker. Our goal is to develop functional materials for fast diagnosis of wound inflammation/infection by using HNE as a ...

Preparation of organic hydrazides [PDF]
, 1959 Thesis (M.A.)--Boston UniversityDue to the actual high price of hydrazine, this chemical cannot be used in an economical preparation of organic hydrazides. A synthesis of such hydrazides can be envisaged by the reduction of N-nitroamides.
