A convenient synthesis of gimeracil

A practical three-step synthetic approach to gimeracil in a 68% overall yield is described, using 2,4-dimethoxypyridine as the starting material with 3,5-dichloro-2,4-dimethoxypyridine and 3,5-dichloro-2,4-dihydroxypyridine as intermediates. The advantages of this procedure include short reaction steps, simple operation and good yield.

Effects of supplemental food on the behaviour and paternity status of male Indigo Buntings (Passerina cyanea)

Breeding is energetically costly and, if energy-limited, birds may alter their time budgets, spending less time engaged in some activities and more time in others. Investigators who have provided breeding birds with supplemental food have noted changes in time budgets, but the extent and types of changes have been found to vary among species.

Now available on Fast Track: Fabricating nano-sized BiVO₄/InVO₄/g-C₃N₄ photocatalysts for efficient degradation of Acid Blue 92 azo dye

Photocatalysis using semiconductors has received considerable interest in both the scientific and engineering areas. Especially, metal oxide semiconductor photocatalysts have been widely studied for environmental applications such as cleaning of air and the removal of hazardous compounds from wastewater. Metal vanadates are a notable category of inorganic nanomaterials that have received attention due to their wide applications and many researchers has ...

Now available on Fast Track - Changing Tetra Pak: from waste to resource 

In recent years, the problem caused by Tetra Pak waste (TPW) has became a topic of great concern to scientists and environmentalists, and commercial companies have also begun to take an interest in developing processes for tackling this issue. In this article, the challenges in the recycling of TPW are described. This article presents the major conclusions of previously published works focussed on the utilisation of TPW for energy and material purposes....
