Abstract:
... Over the past decade use of aerogels has received much attention as an emerging technology for wastewater treatment. However, production of aerogels is not environment-friendly. Owing to its excellent properties such as porosity, three-dimensional structure, being amenable to chemical modifications, it is imperative to devise strategies for their improved production and use. Bioaerogels are non-to ...

Abstract:
... Global warming and salinization are inducing adverse effects on crop yield. Drought priming has been proved to improve drought tolerance of plants at later growth stages, however, whether and how drought priming at early growth stage alleviating salinity stress at later growth stage and improving water use efficiency (WUE) of plants remains unknown. Therefore, two wheat cultivars were subjected to ...

Abstract:
... Glucose and glutamine are two principal nutrients in mammalian cells that provide energy and biomass for cell growth and proliferation. Especially in cancer cells, glutamine could be a main alternative for energy and biomass supply once glucose metabolism is suppressed. Therefore, single inhibition of enzymes in either glucose metabolism or glutaminolysis, though maybe efficient in vitro, is far f ...
