In the study, method of atomic emission and mass spectrometry with inductively coupled argon plasma was used to determine average concentrations macronutrients (Ca, K, Mg, Na, P), essential trace elements (Cu, Fe, I, Mn, Se, Zn) conditionally (B, Co, Cr, V, Si, Li, Ni), as well toxic metals (Al, As, Cd, Hg, Pb, Sr, Sn) in wild berries most often included diets Magadan region residents: Blue hon...

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...

The development of cathode materials with high capacity and cycle stability is essential to emerging electric-vehicle technologies, however, of serious environmental concern is that materials with these properties developed so far contain the toxic and expensive Co. We report here the Li-rich, Co-free Li1+xMO2 (M = Li, Ni, Mn, Fe) composite cathode material, prepared via a template-free, one-st...

Knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. Sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. The method, however, presents some deficiencies, including labor-intensive proced...

A large proportion of the world’s population relies on medicines from the herbal sources. In this review, data about the mineral element content of medicinal and aromatic plants, including major elements, trace elements and toxic heavy metals, will be discussed and compared. Plants and drugs with remarkable elemental compositions will be pointed out. The main focus will be given on plants used ...

objective high concentration of iron and other trace elements could restrict bacterial growth and modify their metabolic pattern as well. however, this study aimed to find out the influence of iron, chromium, cadmium and synergism or antagonism between these elements on the growth of a gram positive bacterium. materials and methods in a series of experiments, bucillus cereus was cultured in a n...
