Residual Resistivity of Some Metallic Elements
In the present article, the residual resistivity of some metallic elements of the periodic table is reported on the basis of model potential formalism. Ashcroft's well known empty core (EMC) model potential is explored first time with five different types of the local field correction functions proposed by Hartree (H), Taylor (T), Ichimaru-Utsumi (IU), Farid et al (F) and Sarkar et al (S) to in...
متن کاملRecent developments in the coordination chemistry of porphyrin complexes containing non-metallic and semi- metallic elements
The tremendous potential for the manifold applications of porphyrins, porphyrazines, and phthalocyanines derives from their photophysical and electrochemical properties, their remarkable stability, and their predictable and rigid structure. These applications include nonlinear optics, catalysts, sensors, actuators, molecular sieves, and therapeutics. All of these properties are modulated by app...
متن کاملMetallic Mineral Elements and Heavy Metals in Medicinal Plants
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 ...
متن کاملContamination by metallic elements released from joint prostheses.
When a metallic implant is in contact with human tissues, the organism reacts and a corrosion process starts. Consequently, we might observe liberation of metallic debris and wear. Our purpose is to measure the contamination and the migration of these metallic elements in the surrounding tissues of the implant. Two types of samples have been studied. First type is sample taken on post-mortem ti...
متن کاملBeta Backscattering by Metallic Elements and Simple Compounds
The aim was to investigate the angular dependence of the β-particle backscatter count rate, using a strontium-90 source. In addition the empirical relationship between the atomic number (Z number) of a scatterer and the count rate at a specific angle was investigated along with consideration of how this relationship behaves with simple compounds. Thick samples are used throughout. A brief inves...
