ZusammenfassungVon Erdalkalimetallionen außer Beryllium ist bekannt, dass sie ein calcimimetisches Verhalten zeigen. Damit ist ihr Schicksal in vivo vorgezeichnet, das in einem beträchtlichen Maße durch den Einbau in Knochengewebe, welches zum Hauptteil aus Hydroxylapatit besteht, charakterisiert ist. In diesem Sinne wurde auch die Verwendung von Radionukliden dieser Elemente als Knochensucher forciert. Mit Ausnahme von Beryllium und Magnesium wurden Tierexperimente und Humananwendungen mit Radionukliden von Calcium, Strontium, Barium und Radium durchgeführt, wobei bis heute lediglich Strontiu

Abstract (sommario):

Abstract Because barium sulfate (BaSO4) is not harmful to the mucosa, it is widely used for gastrointestinal imaging. Barium appendicitis is a very rare complication of barium meals and barium enema. We report a case of acute appendicitis associated with retained appendiceal barium. A 47-year-old man presented with right lower abdominal pain after upper gastrointestinal imaging was performed using barium 1 month earlier. The abdominal plain roentgenogram showed an area of retained barium in the right lower quadrant. Multiplanar reconstruction of computed tomography scans showed barium retentio

Abstract (sommario):

New salts of barium with dicarboxylic acids (glutaric, adipic, pimelic, suberic, sebacic, and dodecanedioic) were synthesized and characterized by powder diffraction techniques. In addition to the basic crystallographic data and chemical analyses of barium glutarate hexahydrate {1}, barium adipate {2}, barium pimelate {3}, barium disuberate {4}, barium sebacate {5}, and barium dodecanedioate {6}, the processes of their thermal decomposition were investigated by XRPD. All the compounds decompose to barium carbonate at temperatures between 400 and 500 °C.

AbstractAcid mine drainage (AMD) is a worldwide problem leading to contamination of water sources. AMD are characterized by low pH and high content of heavy metals and sulphates. The barium salts application presents one of the methods for the sulphates removing from AMD. Barium chloride, barium hydroxide and barium sulphide are used for the sulphates precipitation in the form of barium sulphate. Because of high investment costs of barium salts, barium sulphide is recycled from barium sulphate precipitates. It can be recycled by thermic or bacterial reduction of barium sulphate.

Barium slag, classified as HW47 hazardous waste, is produced in large quantities and has a high accumulation with heavy metal Ba ions that are significantly above the standard levels, posing a serious threat to the ecological environment and the growth of flora and fauna. Before barium slag can be stored, it must undergo harmless treatment, which is costly, and with the current large volume of accumulated barium slag, storage facilities are strained. There is an urgent need for new technologies to extract barium elements from barium slag while achieving reduction in volume. This study first tr

Abstract (sommario):

This study proposes an innovative method for the harmless treatment of barium slag using the industrial by-product Flue Gas Desulfurization Gypsum. Barium slag is a by-product of the barium carbonate production process, and due to its high content of barium ions and corrosive properties, it poses a significant threat to the environment and human health. It is classified as barium-containing hazardous waste (code HW47) in China. In this study, barium slag was optimally combined with FGD gypsum, utilizing a synergistic precipitation mechanism to solidify the easily leachable barium ions and form

Abstract (sommario):

Abstract Quantitative review of oral barium exposure was conducted using drinking water metals data from the confirmed sixfold (18-fold15–39 years) Brisbane Australia invasive breast cancer cluster (IBC) investigation, which also included fivefold duct carcinoma in situ (DCIS). The new approach here was to assess sub-guideline on-site water system barium fluctuations and use cancer slope factor (CSF) firstly to profile match barium as a carcinogen, then correlate risk. Dissolved barium was converting, up to 71%, into non-dissolved forms in the cluster location; with only up to 3% in a comparis

Abstract (sommario):

In this study, polypyrrole was deposited separately on barium titanate, barium titanate-poly (acrylonitrile-co-methylacrylate) nanocomposite-coated textile fabrics by an in-situ chemical polymerization process. Electromagnetic shielding effectiveness, electrical conductivity, chemical structure, and morphology of fabrics were fully characterized and systematically studied for investigation of individual effects of barium titanate, pyrrole polymer, and barium titanate-poly (acrylonitrile-co-methylacrylate) on obtained fabrics’ conductivity and shielding behaviour. Electromagnetic shielding effe

Abstract (sommario):

New iron-based composite materials with addition of barium carbonate (2 to 8 wt% barium carbonate) for friction applications are investigated. The tribological behavior of the studied materials was determined by a pin-on-disk method when a cast iron disk was employed. The addition of 2 wt% barium carbonate determined a significant increase of the average friction coefficient. Instead a further increase of barium carbonate content determined a gradual decrease of this parameter. The improvement of wear resistance was marked out for a barium carbonate content of up to 6 wt%. The optimal ratio be

Abstract (sommario):

This research aims to analyze the characteristics of Barium Hexaferite and iron sand as microwave absorbing materials, their influence on microwave absorption properties, and the frequency range of waves produced by these materials. The research method used is the Co-Precipitation method. Dissolve barium hexapherite and iron sand in distilled water with the appropriate mass ratio. The results of this study show that the synthesis of iron sand and barium hexapherite material produces a single phase material. The single phase material is shown through X-ray diffraction pattern data, namely iron

Abstract (sommario):

Structure information of barium hexaferrite is very important in designing higher efficient synthetic methods and in tailoring the magnetic properties of barium hexaferrite by doping. The structure information of M-type barium hexaferrite has helped to find new efficient routes of hydrothermal and co-precipitation methods in synthesizing barium hexaferrites and in altering their magnetic properties by doping.
