Liquid Metal Cracking – Liquid metal cracking is a specialized form of stress corrosion. The susceptible metal (usually due to residual tensile stresses from fabrication) is attacked (cracked) by a low-melting liquid metal. An example is the cracking of aged Ni-Cr-Fe alloys by silver-base ...

17 is a bar chart that illustrates the calculated mean of the inhibition zone (mm) and the different concentrations of IONPs prepared using Clove or g-Coffee (1000, 500, 250, 125, 62.5 ug/ml) versus diverse species of bacteria. Figure 17 Antimicrobial activity of IONP of both Clove and...
22was generated at the cathode. Unidentified compounds were converted to short chain carboxylic acids, alcohol and ketones, while ammonia was oxidized into N2. Studies with model compounds showed that amides and alpha hydroxyacids yielded carboxylic acids that convert further via (non-)Kolbe chemistry...
This model suits well for gas phase equi- libria but it usually fails to explain the equilibria of heavy metal in solid–liquid phase because the biomass molecules do not organise themselves in a similar packed structure. KT (L mg−1) is the equilibrium binding constant, related to ...
19.A method for making dry precursors for gas filled microbubbles for ultrasonic imaging comprising the steps of:dissolving a mixture of hydrogenated soya lecithin and dicetyl-phosphate in a chloroform solution;evaporating said solution to yield a dried mixture;adding an aqueous liquid to the dried ...
11. A method for uniformly introducing the nano-sized particle of an oxygen storage component prepared by the process of claim 1 into an un-reacted solid fuel, comprising the steps of: a) taking a solution of the oxygen storage component nano-particles and a carrier liquid with particles ...
27. A process according to claim 26 wherein said weak acid is generated by introducing carbon dioxide into said pulp or said washing or dilution liquid. 28. A process according to claim 27 wherein said carbon dioxide is introduced in an amount which is effective in improving the washing, de...
The most commonly used procedures involve high performance liquid chromatography (HPLC) and capillary electrophoresis (CE), but both of these separation techniques are suitable for use only in a laboratory setting as both of the techniques require sophisticated instrumentation, regular maintenance and ...
This separation method is one of the most important for extracting species from liquid media because the retained specie is concentrated in a solid phase. Afterward, a volume of an extract is passed by the solid phase, removing the retained specie to a volume that is considerably lower when ...
