A facile, rapid and green method based on potentiostatic electrodeposition is developed to synthesize a novel H3PMo12O40-Pt/reduced graphene oxide (denoted as PMo12-Pt/rGO) composite. The as-prepared PMo12-Pt/rGO is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The results reveal that graphene oxide (GO) is reduced to th...

It has been demonstrated that radioactive lycopene results from the addition of labeled acetate to intact, green, ripening tomatoes (1, 2). In order to study more closely the metabolic pathway involved in the formation of this carotenoid, attempts to prepare a cell-free system which could synthesize lycopene were carried out. Labeled mevalonic acid could serve as a source of lycopene carbon in ...

The hydration of propargylic alcohols is a green route to synthesize a-hydroxy ketones. Herein a CO2reactive ionic liquid (IL), [Bu4P][Im], was found to display high performance for catalyzing the hydration of propargylic alcohols in the presence of atmospheric CO2, and a series of propargylic alcohols could be converted into the corresponding a-hydroxy ketones in good to excellent yields. In t...

Fluorogenic molecules are important tools for advanced biochemical and biological experiments. The extant collection of fluorogenic probes is incomplete, however, leaving regions of the electromagnetic spectrum unutilized. Here, we synthesize green-excited fluorescent and fluorogenic analogues of the classic fluorescein and rhodamine 110 fluorophores by replacement of the xanthene oxygen with a...

A green protocol has been applied to synthesize a novel series of 3-cyano-2-(tri-O-acetyl-β-D-arabinopyranosylthio)pyridines in a short reaction time, in higher yields and with simpler operations, when compared with the conventional heating method. Deacetylation of the obtained acetylated arabinosides produced 2-(β-D-arabinopyranosylthio)-3-cyanopyridines. The structures of the obtained product...

This study offers a reflection about the ongoing debate on “degrowth” and “green growth”, as depicted in Norwegian mass media. It addresses following two interrelated research questions. How do topics of public debate, where concepts degrowth green growth are used, connect overlap? In these connections overlaps, how relate to each other? We read all articles published Norway ten newspapers maga...

We synthesize a refutationally complete tableau calculus for propositional logic by a new method, using ordered resolution as a procedural framework at the meta level. Algebraically, the calculus solves the word problem for free distributive lattices. Goal-directedness of the construction is enforced by a ne-tuned well-founded ordering on terms, atoms and clauses. The synthesis is performed in ...
