The use of the low voltage power network for data transmission can produce radiated disturbances. In order to determine field limits when using this technique and methods to check this limit, a procedure must be defined and a standard must be written. The ...
Incorporation of a nitrogen functionality into a tripodal N-heterocyclic carbene ligand system affords the first N-anchored tetradentate tris-carbene ligands TIMENR I (R = Me (5a), t-Bu (5b), Bz (5c)). Treatment of the Me derivatized H3TIMENMe3 imid ...
A series of controlled laboratory experiments are carried out in dual Teflon chambers to examine the presence of oligomers in secondary organic aerosols (SOA) from hydrocarbon ozonolysis as well as to explore the effect of particle phase acidity on SOA for ...
The condensation of aryl boronic acids with 2,3-dihydroxypyridine gives boronates, which self-assemble to form tetrameric macrocycles as evidenced by X-ray crystallographic analyses. ...
Two 1,3-dialkyne-functionalized imidazolium chlorides, 1,3-dipropynylimidazolium chloride and 1,3-dipentynylimidazolium chloride, have been prepared from the direct reaction between the appropriate chloroalkyne and (trimethylsilyl)imidazole. Replacement of ...
Piezoelectric micromachined ultrasonic transducers for airborne and immersed applications working in the frequency range from 20 kHz in liquid to 750 kHz in air have been fabricated and characterized, as well as simulated by finite element modelling. The b ...
The magnetic excitation spectrum in the two-dimensional (2D) S = 1/2 Heisenberg antiferromagnet copper deuteroformate tetradeuterate has been measured for temperatures up to T similar to J/2, where J = 6.31 +/- 0.02 meV is the 2D exchange coupling. For T < ...
A. parametric study of the ac loss behavior and the stability of 3 NbTi subsize cable-in-conduit conductors has been performed in the SULTAN test facility. Two of the conductors are distinguished only by the SnAg and the Ni coating of the strands. The effe ...
Solid epoxy resins are produced at Vantico SA by catalyzed reactions of a low-mol. wt. liq. resin (RBL) with bisphenol A (BPA). These reactions lead to solid epoxy resins, which are used in surface coatings or adhesives. The chain lengthening step (advance ...
Palladium-catalyzed Suzuki cross-coupling, Corey's enantioselective alkylation of glycine template, and macrolactamization are key steps in an efficient synthesis of the 15-membered macrocycle I, the A-B biaryl macrocyclic component of RP-66453 (II). Unfor ...
