A new catalyst for an old material: magnetite is a good the selective N-alkylation of aromatic amines using benzylic alcohols as electrophiles. The process could be repeated up to eight times without losing effectiveness. recycling very easy, simple magnet. and discriminate between aliphatic amines, well alcohols, reactions only take place with alcohols.
Microfluidic investigations of flow and transport in porous fractured media have the potential to play a significant role development future subsurface energy resource technologies. However, majority experimental systems date are limited applicability due operating conditions and/or use engineered material micromodels. We developed high pressure temperature microfluidic system that allows for direct observations within geo-material micromodels (e.g. rock, cement) at reservoir conditions. In...
The synthesis of polysubstituted quinolines can be easily and greenly accomplished by the direct reaction between corresponding 2-aminobenzylic alcohol derivative either a ketone or in presence base, without any transition-metal catalyst.
Abstract The first synthesis of polysubstituted quinoline derivatives from aromatic or aliphatic alcohols with RuCl 2 (dmso) 4 as catalyst under solvent‐free conditions is described. reaction involves the in situ oxidation to corresponding carbonyl compounds through a hydrogen‐transfer, followed by Friedländer annulation process. whole process mild, efficient, selective, and high‐yielding single‐step procedure.

This paper presents the fabrication, modeling, and testing of a metamaterial based passive wireless temperature sensor consisting an array closed ring resonators (CRRs) embedded in dielectric material matrix. A mixture 70 vol% Boron Nitride (BN) 30 Barium Titanate (BTO) is used as matrix copper washers are CRRs. Conventional powder compression for fabrication. The feasibility sensing demonstrated up to 200 °C. resonance frequency decreases from 11.93 GHz at room 11.85 °C, providing...
Abstract Furfuryl alcohol was polymerized by trifluoroacetic acid in methylene chloride to give a colored polymer. This polymer possesses two main sequences which the furan rings are connected groups (sequence 1 ) or dimethylene ether 2 ). The is not linear but highly branched, as detected H and 13 C NMR spectroscopy. Variations of experimental conditions, such presence air, concentration, reaction temperature solvent, do allow significant increase structure However, an concentration produce...
Temperature monitoring for energy generation systems plays an important role the control of overall safety and efficiency. To run system at optimum operating conditions, it is to measure real-time temperature. Furthermore, harsh environment temperature sensing desired, since most sensors in are exposed high temperature, pressure, corrosive environments. Lithium niobate (LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> ) has Curie...
