Different cyanogenic bacterial strains (Chromobacterium violaceum, Pseudomonas fluorescens, Bacillus megaterium) were cultivated under cyanide-forming conditions in the presence of metal-containing solids such as nickel powder or electronic scrap. All microorganisms were able to form water-soluble metal cyanides, however, with different efficiencies. C. violaceum was able to mobilize nickel as ...
2,2’-Bithiophene-5-carboxylic acid (BTA) thin-films on platinum (Pt) electrodes were electrochemically prepared in acetonitrile solution containing 0.1 M tetrabutylammonium perchlorate (TBAP) and 0.05 M BTA. These films were complexes with several metal ions such as Cu, Ag and Co. Their structural characteristics were compared with those of powder complexes chemically prepared from BTA and the ...
While GDMS is the technique of choice for high sensitivity metals and semiconductor analyses, there are no commercially available radio frequency-GDMS sources. Thus, bulk non-conductive materials must be ground to a powder, mixed with metal, and pressed to form a conductive disk. The analysis of thick oxide or polymer layers is not available directly. In some cases, a conductive metal mask (cal...
In an effort to better understand the structural changes occurring during hydrogen loading of erbium target materials, we have performed in-situ D2 loading of erbium metal (powder) at temperature (450C) with simultaneous neutron diffraction analysis. This experiment tracked the conversion of Er metal to the erbium deuteride (solid-solution) phase and then on to the (fluorite) phase. Complet...
Background and Objectives: Breakfast-chocolate is high in fat and calorie; hence, its consumption is limited for people suffering from certain diseases such as obesity and diabetes. Therefore, replacement of fat and milk powder with compounds based on carbohydrate and protein with low digestibility can decrease calories of this product and made it consumable for patients with lactose intoleranc...
Particle size enlargement is the process of transforming fine particles into larger particles by the introduction of external forces, and is a value-added step in many processes involving powdered materials. There are many different reasons to enlarge particle size, including increased flowability and improved product shape and appearance. With the multitude of options available to achieve enla...
The production of vacuum dried egg powder through a simplified technique was studied. The advantage of egg powder with its production and variation in its technology which helps for a better quality and cost efficient product was tested. Eggs as a raw source were collected from the local poultry farm and processes for production were carried out. High risk factors like, reduced glucose in the d...
from powder characterisation and how the data correlates to process performance and drug product quality in solid dosage form develop ment projects. Data from two development studies will be shown. The development and manufacturing of solid dosage forms relies heavily on powder material. API and tablet excipients are most often handled as a granular material. The powders are mixed and compresse...
Neutron powder diffraction measurements were carried out on the evacuated and CO2-loaded Prussian blue analogue, Fe3[Co(CN)6]2, identifying two distinct CO2 adsorption sites: site A, in which CO2 uniquely bridges between two bare-metal sites, and site B, in which it interacts in a face capping motif. The saturation of site A at low loadings of CO2 demonstrates the favourable nature of the inter...
Reactive, thermal degradation of py2Pt[MoCp(CO)3]2, (Me)(cod)PtMoCp(CO)3, orfPt3ðdppmÞ3ðCOÞ1⁄2MoðCpÞ g[BPh4]/Vulcan carbon powder composites affords Pt–Mo/carbon nanocomposites containing metal nanoparticles of approximate compositions, PtMo2, PtMo, or Pt3Mo, widely dispersed on the carbon support. Total metal loadings range from 29–58 wt%. When tested as an anode electrocatalyst in a PEM fuel ...
