Coordination number is one of the most fundamental characteristics of molecular structures. Molecules with high coordination numbers often violate the octet and the 18 electron rules and push the boundary of our understanding of chemical bonding and structures. We have been searching for the highest possible coordination number in a planar species with equal distances between the central atom a...

Despite arrowroot’s (Maranta arundinaceae L.) appeal in several industry sectors, which indicates high potential for large-scale production, few studies have investigated the nutritional status of this crop species. Given economic relevance and limited data literature, objective work was to evaluate nutritive effect ovine biofertilizer cultivation arrowroot ‘comum’, two evaluation periods 180 2...

A blanket fertilizer was recommended by the Department of Agriculture (DOA) for all species cabbage. However, application is needed to be site-specific. Hence a field experiment conducted at Ambalangoda during Maha season in 2019 with objective evaluating effect Calcium (Ca), Magnesium (Mg) and Boron (B) on yield Quality cauliflower. Batapola soil analyzed available nutrients identified most de...

the performance of msu-s and its forms modified with phosphotungstic acid (hpw) and nickel (ni) for the desulfurization and denitrogenation of model diesel fuel were studied. according to the results of the characteristic tests (n2 adsorption-desorption, xrd, sem, and nh3-tpd), heteropoly acid incorporation causes higher acidity along with a negligible loss of structural aspects, while ni impre...

in order to evaluate the effect of increasing soil soluble phosphorus (p) and its effect on nitrogen (n) and p uptake, p uptake efficiency and p harvest index of black seed (nigella sativa l.) in a calcareous soil; a field experiment was conducted as factorial layout based on a randomized complete block design with three replications at research station, faculty of agriculture, ferdowsi univers...
