A near-infrared chemosensor for palladium based on the Tsuji-Trost reaction was developed. It displayed specific and ratiometric fluorescent responses toward palladium with a distinct color change from green to blue in aqueous media. PEG400 was employed as the reducing agent and palladium ligand instead of water-insoluble triphenylphosphine. The chemosensor's bioimaging potential was demonstrat...

Experiments using China Lake type calorimetric cells produced excess power in three out of three experiments and no excess power in three control studies. A detailed analysis is presented for two experiments using the China Lake cells. Anomalous thermistor signals in Cell A suggest the emission of electromagnetic radiation from the active palladium cathode. Experiments in Fleischmann-Pons type ...

RNA sequences have been discovered that mediate the growth of hexagonal palladium nanoparticles. In vitro selection techniques were used to evolve an initial library of approximately 10(14) unique RNA sequences through eight cycles of selection to yield several active sequence families. Of the five families, all representative members could form crystalline hexagonal palladium platelets. The pa...

2,5-Furan dicarboxylic acid (FDCA) is a bio-based chemical used as feedstock for wide range of industrial applications - particularly the bioplastic industries. It derived from 5-hydroxymethylfurfural (HMF) through reaction oxidation using either homogeneous or heterogeneous catalysts. According to advantages catalysts, this research aims seek novel catalyst type with high selectivity and activ...

With the increasing importance of “ heavy water” as a moderator in nuclear reactors there arises a pressing need for a more efficient method of separating hydrogen isotopes. In a report by 0. N. Salmon to the U.S. Atomic Energy Commission (AEC Research and Development Report KAPL 1272) a process is described which aims to improve the method of separation by the electrolysis of water. This proce...

A highly selective ratiometric fluorescent chemodosimeter derived from 4-hydroxynaphthalimide was designed and synthesized to image palladium species in living cells by virtue of a palladium-catalyzed depropargylation reaction, and it could monitor three typical palladium species (0, + 2 and + 4) without additional reagents.

[reaction: see text] A novel palladium-catalyzed coupling reaction between two Csp(3)-Csp(3) centers has been investigated. This protocol is initiated by the oxidative addition of an alpha-halo carbonyl compound to a palladium(0) species, followed by the double transmetalation. The key dialkyl palladium intermediate undergoes reductive elimination to form the desired coupling product.

Phytochemical based synthesis of palladium nanoparticles by bioreduction of medicinally potent plant extract Coleus amboinicus is investigated in the present study. Treatment of palladium chloride with Coleus amboinicus extract resulted in the formation of palladium nanoparticles. The formation of palladium nanoparticles were confirmed using UV-vis, FTIR, TEM and XRD. Polyols such as flavones, ...

In a palladium-catalyzed oxidative esterification, hydrosilane can serve as an activator of palladium catalyst with bismuth, thus leading to a novel ligand- and silver-free palladium catalyst system for facile oxidative esterification of a variety of benzylic alcohols in good yields.
