Methods for forming melt processable, actinic radiation polymerizable and crosslinkable adhesives are described. In certain versions, the adhesives or pre-adhesive compositions include two initiators and are polymerized and/or crosslinked by exposure to actinic radiation such as UV light or electron beam radiation. Also described are pre-adhesive compositions including polymerizable monomers, articles including the adhesives, and various methods and systems related to the adhesives and their application. In addition, various apparatuses are described for polymerizing or crosslinking the compositions.

Described herein are various methods, systems, and apparatus for reducing and eliminating biofilms from hydrocarbons. A combination of oxidizing agents and radiation of certain wavelengths forms a synergistic reaction. The synergistic reaction generates EMODs, which are effective in reducing microbial count and eliminating or blocking biofilm formation, particularly in anaerobic environments. This synergistic reaction has a relationship to EMOD creation and has a detrimental effect on Microbial Contamination (MC), Microbial Influenced Corrosion (MIC) and biofilm creation. MC, MIC and biofilm can be eliminated or greatly reduced with the treatment methods in or on equipment including pipelines, storage tanks, and refinery processing equipment.

The disclosure relates to a method for forming aryl carbon-nitrogen bonds and to photoreactors useful in these and other light-driven reactions. The method comprises contacting an aryl halide with an amine in the presence of a Ni salt catalyst solution and an optional base, thereby forming a reaction mixture; exposing the reaction mixture to light under reaction condition sufficient to produce the aryl carbon-nitrogen bonds. In certain embodiments, the amine may be present in a molar excess to the aryl halide. In certain embodiments, the Ni salt catalyst solution includes a Ni(II) salt and a polar solvent, wherein the Ni(II) salt is dissolved in the polar solvent. In certain embodiments, the reactions conditions include holding the reaction mixture at between about room temperature and about 80 C. for between about 1 hour and about 20 hours such that at least about 50% yield is obtained.

Apparatus and methods for facilitating an intramolecular reaction that occurs in single collisions of CO.sub.2 molecules (or their derivatives amenable to controllable acceleration, such as CO.sub.2.sup.+ ions) with a solid surface, such that molecular oxygen (or its relevant analogs, e.g., O.sub.2.sup.+ and O.sub.2.sup.? ions) is directly produced are provided. The reaction is driven by kinetic energy and is independent of surface composition and temperature. The methods and apparatus may be used to remove CO.sub.2 from Earth's atmosphere, while, in other embodiments, the methods and apparatus may be used to prevent the atmosphere's contamination with CO.sub.2 emissions. In yet other embodiments, the methods and apparatus may be used to obtain molecular oxygen in CO.sub.2-rich environments, such as to facilitate exploration of extraterrestrial bodies with CO.sub.2-rich atmospheres (e.g. Mars).

A method of making a multicomponent photocatalyst, includes inducing precipitation from a pre-cursor solution comprising a pre-cursor of a plasmonic material and a pre-cursor of a reactive component to form co-precipitated particles; collecting the co-precipitated particles; and annealing the co-precipitated particles to form the multicomponent photocatalyst comprising a reactive component optically, thermally, or electronically coupled to a plasmonic material.
