Solder flux which leaves corrosion-resistant coating Patent
Hydrazine monoperfluoro alkanoate solder flux leaving corrosion resistant coating, for metals such as coppe
Solder flux leaves corrosion-resistant coating on metal
A soldering flux consisting of perfluoro-octanoic acid hydrazine provides a corrosion resistant film on metal surface, particularly copper. It is ineffective for soldering aluminum
Some design considerations, large expulsion bladders for nitrogen tetroxide and hydrazine
Chemical compatibility, permeation, and fuel tank bladder collapse considered for Advanced Liquid Propulsion System /ALPS
Apparatus to measure the mid-infrared spectral emittance of cold powders in a vacuum
Apparatus for measuring mid-infrared spectral emission from cold powders in vacuu
Reusable chelating resins concentrate metal ions from highly dilute solutions
Column chromatographic method uses new metal chelating resins for recovering heavy-metal ions from highly dilute solutions. The absorbed heavy-metal cations may be removed from the chelating resins by acid or base washes. The resins are reusable after the washes are completed
Climate Weirding and Queering Nature: Getting Beyond the Anthropocene
Though many scientists and scholars of the environmental humanities are referring to the current geological era as the anthropocene, this article argues that there are some problems with this trope and the narrative that emerges from it. First, responsibility for the current era of climate weirding is not shared equally, some humans are way more responsible than others. Second, the claim of the anthropocene works rhetorically to maintain a sense of human exceptionalism from the rest of the evolution of life on the planet. Third and finally, the suggestion that this geological era be named the anthropocene suggests that the problem and the solution to our ecological crisis lie with Homo sapiens. Does this not re-create the sense of mastery that has fueled contemporary planetary ills in the first place? This paper argues that the idea of agency must be reconfigured and redistributed throughout the planetary community in order to deal with the wicked problems arising from climate weirding and an uncertain future
