In addition, Nemergent provided a core element, the MCPTT client and server components, while Frequentis provided the control room solution with their Multimedia-Collaboration Platform 3020 LifeX, enabling cross-coupling (LTE, TETRA, Emergency Telephone Calls) and mixing media as well as tacking the resources on the embedded geographical information system (GIS).

They explain the development of boronic acid-based supramolecular systems; the investigation of boron-containing aspects by NMR (nuclear magnetic resonance) spectroscopy; the use of boronic esters in cross-coupling reactions; boronic acid systems that can bind to nucleophilic species, 1,2-diols, and arylboronates; the development of boronic acids towards optical, continuous, sensing of saccharides; and boronic acid-based systems for enantioselective fluorescent recognition.
Over the past decade, as a member of York University's Department of Chemistry, Organ and his team developed one of the world's most widely used systems for palladium-mediated cross-coupling, pyridine-enhanced precatalyst preparation stabilization and initiation (PEPPSI) and explored the concept of using microwaves to promote capillary flow for organic synthesis.
Heck's discoveries laid the foundation for all modern cross-coupling reactions.
These breakthroughs include (i) realization that Me-branched chiral compounds can be synthesized by ZACA reaction via a few alternate and mutually complementary routes (Scheme 5), (ii) unexpected finding that 2,4-dimethyl-1-hydroxybutyl moieties can be readily purified by ordinary chromatography (Scheme 6), (83) and (iii) subsequent Pd- or Cu-catalyzed cross-coupling proceeds with essentially full (>99%) retention of newly formed chiral centers (Scheme 7).
Significant cross-coupling is observed between the actions of the rotors, with each rotor influencing both angle positions [1].
Subsequent cross-coupling of protected-acetylene to the core BC, afforded a monomer of benzo[c]cinnoline ethynyl-ene.
Chemists review the current state of the formation of copper-mediated carbon-heteroatom bonds and carbon-carbon bonds, and applications of copper-catalyzed cross-coupling reactions in heterocycles, natural products processes, and sustainable chemistry.
During transition to forward flight, today's prop-rotor center of gravity (CG) shifts and cross-coupling challenges are not encountered by traditional rotorcraft.
The comprehensive silicon compound handbook contains information on silanes for coupling agent applications with new functional and non-functional dipodal structures, silanes for hydrophilic surface treatment with a greater range of PEG substitution, new silanes for cross-coupling applications in organic synthesis, silanes and silicones for "click chemistry," including new azide and acetylene functional silanes, volatile carbosilane and oligosilanes for semiconductor applications, symmetric and dual functional macromers for biomaterials and microfluidics, liquid silsesquioxane t-resins for high temperature coatings, and silanes and silicones with high refractive index (RI) and chromogenic properties.
When high selectivity and/or other requirements cannot be met by the filters with a single pair of transmission zeros, cross-coupling topologies are widely used to introduce additional transmission zeros for BPF applications [23-26].
