Electronic structure of undoped and potassium doped coronene investigated by electron energy-loss spectroscopy [PDF]
We performed electron energy-loss spectroscopy studies in transmission in order to obtain insight into the electronic properties of potassium intercalated coronene, a recently discovered superconductor with a rather high transition temperature of about 15\,K.

Values of sodium, ionized calcium, potassium and chloride obtained by ion-selective electrode method, from serum and blood samples of healthy cats, were compared. Serum ionized calcium value was lower (5.2mg/dl) than blood ionized calcium (5.4mg/dl), and

Evidence for phase formation in potassium intercalated 1,2;8,9-dibenzopentacene [PDF]
We have prepared potassium intercalated 1,2;8,9-dibenzopentacene films under vacuum conditions. The evolution of the electronic excitation spectra upon potassium addition as measured using electron energy-loss spectroscopy clearly indicate the formation of particular doped phases with compositions K$_x$dibenzopentacene ($x$ = 1,2,3).

Effect of the fertilization on the population of Corythaica cyathicollis in eggplants in function of the collection period [PDF]
Corythaica cyathicollis (Costa, 1864) is one of the main pests on Solanum melongena and it is known to cause serious damage to the culture. To determine the effect of N and K fertilization on eggplants, a study on the occurrence of C.

Generating potassium abundance variations in the Solar Nebula [PDF]
An intriguing aspect of chondritic meteorites is that they are complementary: while their separate components have wildly varying abundances, bulk chondrites have nearly solar composition. This implies that the nearly-solar reservoirs in which chondrites were born were in turn assembled from sub-reservoirs of differing compositions that birthed the ...

The retranslocation of boron is influenced by the nutritional status of cherry tomato plants
Boron (B) retranslocation may confer greater tolerance to B deficiency or toxicity, resulting in plants and fruits with better nutritional quality. Most plants do not demonstrate phloem mobility for B; however, some plants have natural mobility and ...
