Innovative and safe method to conduct high temperature halogenation of metallic alloys

The present invention discloses a method and system for conducting high temperature corrosion tests on metallic alloys without the need for extensive laboratory equipment and attendant safety measures through the use of a two-compartment ampoule where a vestibule connects these two compartments. A pre-selected mixture of salts is placed in one compartment in order to generate a specific partial pressure of halogen gas; and a metallic alloy is placed in the other compartment. The ampoule is then heated to a pre-determined temperature and held at this temperature for a pre-determined time period. A halogen gas of a specific partial pressure is thereby generated from the mixture of salts which comes into contact with the metallic alloy. Because the ampoule creates a sealed environment, the metallic alloy is under constant halogenation during the pre-determined time period. The metallic alloy is removed for examination when the pre-determined time period expires.

METHODS AND SYSTEMS FOR TREATING MEIBOMIAN GLAND DYSFUNCTION USING RADIO-FREQUENCY ENERGY

A method of treating meibomian gland dysfunction is disclosed. The method includes directing RF energy to an internal portion of a meibomian gland, selectively targeting an obstruction within a duct of the meibomian gland with the applied RF energy to melt, loosen, or soften the obstruction, and expressing the obstruction from the duct of the meibomian gland. An apparatus for treating meibomian gland dysfunction is also disclosed. The apparatus comprises at least one RF electrode configured to direct RF energy to an internal portion of a meibomian gland located in an eyelid of an eye, the at least one RF electrode further configured to selectively target an obstruction within a duct of the meibomian gland with the applied RF energy to melt, loosen, or soften the obstruction. The apparatus also comprises at least one expressor configured to express the obstruction from the duct of the meibomian gland.

Reagents For Oxidizer-Based Chemical Detection
20170299566 · 2017-10-19 ·

Reagents and methods are disclosed for detection of oxidizers and inorganic salts and other analytes of interest. The reagents can interact with their target analytes, especially oxidizer compositions or oxidizer-based explosives, to selectively enhance their ionization yield, interacting by chemical reaction or by forming an associative adduct which facilitates their detection. For example, the reagents can adduct with the counter-ion of the intended analyte for improved direct detection and/or react chemically via acid-base reactions to produce a new product for detection. In another aspect of the invention, reactive reagents and methods are also disclosed that facilitate indirect detection of the analyte at lower temperatures based on reduction-oxidation (redox) chemistry. These reagents are particularly useful in detecting oxidizer analytes.
