Subject:
amines; aminolysis; bisphenol A; bottles; depolymerization; fluorescence; foods; gas chromatography; high performance liquid chromatography; human health; mass spectrometry; milk; protein degradation
Abstract:
... The key block for the production of polycarbonate (PC) is bisphenol A (BPA). Recent studies have proven that this monomer is able to migrate from PC baby bottles into food simulants and, although this is a polemical subject, numerous investigations indicate that BPA may have an effect on the human health. For these reasons, BPA safety regarding human exposure has recently become an alarming issue. ...

ISSN:

Subject:
aminolysis; azides; crosslinking; hemoglobin
Abstract:
... A cross-linked hemoglobin bis-tetramer with oxygenation properties appropriate for a red cell substitute is produced by CuAAC conjugation of a dialkyne and two equivalents of an azide of β,β-cross-linked hemoglobin. The latter is formed efficiently by the aminolysis of the 3,5-dibromosalicylate ester of the β-82-β′-82-bis trimesyl amide of human hemoglobin A with (4-aminomethyl)benzyl azide. ...

Abstract:
... The synthesis of block copolymers via polymer conjugation of well-defined building blocks offers excellent control over the structures obtained, but often several coupling strategies need to be explored to find an efficient one depending on the building blocks. To facilitate the synthesis of polymers with adjustable functional end-groups for polymer conjugation, we report on the combination of act ...

Subject:
Elaeis guineensis; aminolysis; fractionation; fronds; lignin; mesocarp; oilseed cakes; oxidation; water treatment
Abstract:
... In order to investigate the potential for efficient utilization of oil palm (Elaeis guineensis), supercritical water treatment (at 380°C and 100 MPa for 8 s) was applied to fractionate extractives-free samples into water-soluble portion and water-insoluble portion. The water-insoluble portion was further fractionated into methanol-soluble portion and methanol-insoluble residue. Samples were prepar ...

Abstract:
... The paper reviews the problem due to the use and disposal of synthetic polymers to the environment and its solutions; in particular poly (ethylene terphthalate). Wide spread application and non-biodegradability of the PET creates huge amounts of waste and disposal, tend to a serious problem. The most important cause for recycling and reprocessing the waste PET has arisen from the awareness and con ...

Abstract:
... Stable and surface-modified films with regular porous arrays were created by crosslinking honeycomb structured porous films prepared via breath figures from poly(styrene-co-maleic anhydride). The formation of open or closed pores of the films was controlled by the addition of a polyion complex. Subsequent crosslinking of the films with 1,8-diaminooctane led to films, which maintain their structure ...
