From:Journal of Analytical Chemistry (Vol. 75, Issue 3) Peer-ReviewedA possibility of studying carbon nanotubes by X-ray fluorescence spectrometry using reference samples prepared from carbon materials more accessible than purified carbon nanotubes (carbon black, Sibunit, and activated...
-
From:Science (Vol. 293, Issue 5536) Peer-ReviewedBimetallic electrodes are used in a number of electrochemical processes, but the role of particular arrangements of surface metal atoms (ensembles) has not been studied directly. We have evaluated the...

From:Nature (Vol. 580, Issue 7802) Peer-ReviewedMulticomponent reactions are relied on in both academic and industrial synthetic organic chemistry owing to their step- and atom-economy advantages over traditional synthetic sequences.sup.1. Recently,...
-
From:Nature (Vol. 580, Issue 7805) Peer-ReviewedThe addition of a methyl group to a drug molecule can greatly alter the drug's pharmacological properties. A catalyst has been developed that enables this 'magic methyl effect' to be rapidly explored for drug discovery....
-
From:Journal of NanomaterialsPeer-ReviewedOxidation reactions may be considered as the heart of chemical synthesis. However, the indiscriminate uses of harsh and corrosive chemicals in this endeavor are threating to the ecosystems, public health, and...

From:Nature (Vol. 586, Issue 7831) Peer-ReviewedA study of the industrial catalyst titanium silicalite-1 suggests that the conventional view of the structure of its active sites is wrong. The findings might enable further optimization of related industrial catalysts....
-
From:Science (Vol. 308, Issue 5718) Peer-ReviewedStrategies for homogeneous catalysis of bimolecular reactions tend to focus on activating only one of the two reactants. Recently, several bimetallic systems have been developed for dual activation, but the interactions...
-
From:Nature (Vol. 586, Issue 7831) Peer-ReviewedTitanium silicalite-1 (TS-1) is a zeolitic material with MFI framework structure, in which 1 to 2 per cent of the silicon atoms are substituted for titanium atoms. It is widely used in industry owing to its ability to...
