New polytopes from products
We construct a new 2-parameter family Emn, m, n ≥ 3, of self-dual 2-simple and 2-simplicial 4-polytopes, with flexible geometric realisations. E44 is the 24-cell. For large m, n the f -vectors have “fatness” close to 6. The Et-construction of Paffenholz and Ziegler applied to products of polygons yields cellular spheres with the combinatorial structure of Emn. Here we prove polytopality of thes...
متن کاملCatalytic conversion of furfural towards fuel biocomponents
Introduction The climate change, the perspective of finishing oil resource and its rising prices led the world to search for an alternative ways of acquiring valuable chemicals and fuels. In recent years technologies of production the most important chemicals for chemical and automotive industries are developed, especially these which use a renewable source of biomass (biodegradable fraction of...
متن کاملNew products from partial oxidation of glycerol
A surplus of glycerol production due to several reasons has initiated investigation of several routes of oxidative glycerol upgrading. Among the reaction products are substances such as dihydroxyacetone and several acids from oxidative upgrading of glycerol. Several routes of chemical oxidation and electrochemical oxidation have been published in literature. The ongoing project has focused on t...
متن کاملNew natural products from medicinal plants of Pakistan
A number of new natural products have been isolated from medicinal plants of Pakistan. Some of them have exhibited antifungal activities. Structure of those compounds were determined with the help of spectroscopic studies. 1. ANTIFUNGAL STEROIDAL LACTONES FROM WZTHANIA C O A G W C E Withanolides (c28 steroidal lactones) have been isolated from many plants of the family Solanaceae such as Withan...
متن کاملAgrochemical Discovery: Finding New Fungicides From Natural Products
The continuing development of fungicide resistance in plant and human pathogens necessitates the discovery and development of new fungicides. Discovery and evaluation of natural product fungicides is largely dependent upon the availability of miniaturized antifungal bioassays. Essentials for natural product bioassays include, sensitivity to microgram quantities, selectivity to determine optimum...
