This paper investigates how the thermal diffusion of boron in silicon is influenced by a high energy fluorine implant with a dose in the range 531014–2.331015 cm−2. Secondary Ion Mass Spectroscopy (SIMS) profiles of boron marker layers are presented for different fluorine doses and compared with fluorine profiles to establish the conditions under which thermal boron diffusion is suppressed. The...
Since 1963, evidence has accumulated that suggests boron is a safe and effective treatment for some forms of arthritis. The initial evidence was that boron supplementation alleviated arthritic pain and discomfort of the author. This was followed by findings from numerous other observations epidemiologic and controlled animal and human experiments. These findings included a) analytical evidence ...
introduction: boron is one of the eight essential micronutrients required for plant growth and development. the optimal concentration range (between deficiency and phytotoxicity) for boron is narrower than for other plant essential nutrients. generally, irrigating water containing concentrations of b greater than 1 mg l-1 would be detrimental for most plants. although, there are a large number ...
As we examine the role of micronutrients in turfgrass nutrition, we enter murky waters when we consider the functions of boron. There is a scarcity of specific research on turfgrasses, so there remain questions about its roles. Since this subject has been reviewed recently (Blevins and Lukaszewski 1998), we interpret the current state of knowledge about boron's importance to turfgrass managemen...
The boron contents of 68 edible common macrofungi of Hungary were analysed. The average boron content of the examples was 11.74 mg/kg dry mass, this is higher than the average value of green plants of Hungary (7.4 mg/kg dry mass). Although the highest boron contents were found in the examples from woods near Budapest, the differences between the various sites are not significant. It seems that ...
