20120097522 | SYNTHESIS OF ZINC-OXIDE NANOPARTICLES AND THEIR USE FOR PHOTO CATALYTIC DEGRADATION OF CYANIDE - A simple, room-temperature method of producing zinc oxide nanoparticles was established by reacting zinc nitrate hexahydrate and cyclohexylamine (CHA) in either aqueous or EtOHic medium. Particles of polyhedra morphology were obtained for zinc oxide, prepared in EtOH (ZnO | 04-26-2012 |
20130296604 | METHOD OF MAKING AND USING NANO-BIMETALLIC CATALYST TO PRODUCE ADIPIC ACID - A bimetallic catalyst supported on a transition metal oxide is described. A method to make and use the bimetallic catalyst is also described. A method for preparing supported bimetallic catalysts of coinage group metal and a combination of a coinage group metal and a platinum metal group is described. A method for direct synthesis of adipic acid (AA) adopting green catalytic oxidation route of cyclohexane (CH) using the bimetallic catalysts is described. The reaction to convert CH into AA in the presence of bimetallic catalyst is carried in an autoclave in the temperature range of 25 to 300° C. The CH conversion was over 21% with AA selectivity of 34% and ca. 63% selectivity of cyclohexanone and cyclohexanol together over Au—Pd/TiO | 11-07-2013 |
20140179950 | METHOD OF MAKING ADIPIC ACID USING NANO CATALYST - A method for direct synthesis of adipic acid (AA) adopting green catalytic oxidation route of cyclohexane (CH) using the bimetallic catalysts is described. The reaction to convert CH into AA in the presence of bimetallic catalyst is carried in an autoclave in the temperature range of 25 to 300° C. The CH conversion was over 21% with AA selectivity of 34% and ca. 63% selectivity of cyclohexanone and cyclohexanol together over Au—Pd/TiO | 06-26-2014 |

20130168328 | SYNTHESIS OF COPPER OXIDE- DOPED ZINC-OXIDE NANOPARTICLES AND THEIR USE - A simple, room-temperature method of producing CuO-doped zinc oxide nanoparticles was established by reacting zinc nitrate hexahydrate, copper nitrate trihydrate and cyclohexylamine (CHA) at room temperature. These nanoparticles may be used for photocatalytic degradation of cyanide in aqueous solutions. The degradation of cyanide is effective because electrons transfer from the p-type copper oxide to the n-type zinc oxide. | 07-04-2013 |

20150327691 | MULTI-FUNCTIONAL HOMECARE DEVICE - A multi-function homecare system including a dispensing device having a housing, a display device, a video camera, a speaker, a plurality of compartments, a cover for the plurality of compartments, and a control unit. The control unit of the dispensing device may be operable to issue an alarm and open the cover when a current date and time matches a prescription schedule stored on the control unit. The multi-functional homecare system may further include a controlling device that includes a control unit that is operable to transmit a new prescription schedule to the dispensing device in order to replace a previous prescription schedule. | 11-19-2015 |

20150181847 | FISHING CAPSULES - A fishing device including a lure body portion, a plurality of pH sensors, a water immersion sensor, a closed rigid container containing pressurized content and connected to the pH sensor, a balloon of a predetermined size, connected to the closed rigid container, a trackable chip configured to provide the location of a caught fish within a predetermined geographical location and a plurality of emitters connected to the sensors and configured to emit different predetermined signals. This device improves fishing by significantly reducing the use of energy and time. Once a fish digests a fishing capsule the pH sensor detects digestions and the water immersion sensor stops detecting water the closed rigid container will be activated, and the pressurized content will inflate the balloon inside the stomach of the fish causing it to float to the surface. | 07-02-2015 |

20150319149 | CRYPTOGRAPHIC METHOD AND SYSTEM FOR SECURE AUTHENTICATION AND KEY EXCHANGE - A method and algorithm of authentication between parties includes receiving a randomly generated binary string. A shared secret of the parties is combined with the randomly generated binary string to form a new binary string. A binary pair (A, B) is initiated; a first bit of the new binary string is read. A current value of B is added to A when the read bit is zero, and a current value of A is added to B when the read bit is one. A next bit of the new binary string is read. The steps of adding the current values and reading a next bit are repeated until all bits have been read. A resulting binary pair (A, B) is returned after all of the bits have been read. Ephemeral Diffie-Hellman public keys are securely exchanged between the parties. Challenge responses are exchanged and a session key is agreed upon. | 11-05-2015 |
