| 20100326840 | PROCESS FOR THE RECOVERY OF TELLURIUM FROM MINERALS AND/OR ACIDIC SOLUTIONS - A process and method for recovering elemental tellurium from minerals and acidic solutions using a reducing sugar as the reducing agent in order to reduce and precipitate tellurium as tellurium dioxide (TeO | 12-30-2010 |
| 20110315561 | TREATMENT OF SOLUTIONS OR WASTEWATER - A method for treating a wastewater stream containing organic material or inorganic material comprising passing the wastewater stream to an anode or a cathode of a bioelectrochemical system to thereby alter the pH of the wastewater stream to: a) reduce the pH of the stream passed to the anode to minimise or suppress precipitation of dissolved cations; or b) increase the pH of the stream passed to the cathode to produce an alkaline stream; or c) reduce the pH of the stream passed to the anode to produce an acid containing stream. In one embodiment, a caustic soda solution is produced at the cathode and recovered for storage and subsequent use. | 12-29-2011 |
| 20120012468 | METHOD AND APPARATUS FOR PRODUCING AND SEPARATING COMBUSTIBLE GASSES - The electrolysing apparatus ( | 01-19-2012 |
| 20130134051 | FLEXIBLE SUBSTRATE PROCESSING APPARATUS - To provide a flexible substrate processing apparatus which allows the stable reduction of an oxide contained in a film-like structure body formed on a flexible substrate. The apparatus has a substrate carrying-out portion where a flexible substrate on which a film-like structure body is formed is unwound; a reduction treatment portion where an oxide contained in the film-like structure body formed on the flexible substrate is electrochemically reduced; a washing portion where the flexible substrate and the film-like structure body are washed; a drying portion where the flexible substrate and the film-like structure body are dried; and a substrate carrying-in portion where the flexible substrate on which the film-like structure body is formed is taken up. | 05-30-2013 |
| 20150021196 | Electrochemical method of producing nano graphene platelets - A method of producing nano-scaled graphene platelets with an average thickness smaller than 30 nm from a layered graphite material. The method comprises (a) forming a carboxylic acid-intercalated graphite compound by an electrochemical reaction; (b) exposing the intercalated graphite compound to a thermal shock to produce exfoliated graphite; and (c) subjecting the exfoliated graphite to a mechanical shearing treatment to produce the nano-scaled graphene platelets. Preferred carboxylic acids are formic acid and acetic acid. The exfoliation step in the instant invention does not involve the evolution of undesirable species, such as NO | 01-22-2015 |
| 20150053572 | HYDROMETALLURGICAL PROCESS FOR THE RECOVERY OF TELLURIUM FROM HIGH LEAD BEARING COPPER REFINERY ANODE SLIME - A hydrometallurgical process is provided for the recovery of tellurium as elemental tellurium powder from copper refinery anode slime containing high amount of lead. The process involves the removal of copper and lead from anode slime followed by the recovery of tellurium as elemental powders. An economical and environment friendly process is provided for producing tellurium from a high lead bearing anode slime as it involves only hydrometallurgical techniques and thereby avoids emission of any polluting gases and has an efficiency of 85 to 90%. The developed process of recovering tellurium as elemental powders from copper refinery anode slime is beneficial in the production of pure tellurium instead of tellurium compounds. It helps raise the profit margin of a non-ferrous metal industry dealing with extraction of copper from ores and treatment of anode slime for the recovery of other metal values. | 02-26-2015 |
| 20160115601 | ELECTROCHEMICAL PROCESS FOR PRODUCTION OF GRAPHENE - A process of producing graphene and/or graphite nanoplatelet structures by the electrochemical reduction of carbon oxide in an electrochemical cell is provided, wherein the cell includes (a) a negative electrode including a transition metal, transition metal-containing alloy, transition metal-containing oxide, transition metal containing ceramic, or a combination thereof; (b) a positive electrode; and (c) an electrolyte; wherein the process includes the step of passing a current between the electrodes in the presence of the carbon oxide. | 04-28-2016 |
