Assessing soil water repellency of a sandy field with visible near infrared spectroscopy
(Scopus, 2015)
Soil water repellency (WR) is a widespread phenomenon caused by aggregated organic matter (OM) and layers of hydrophobic organic
substances coating the surface of soil particles. These substances have a very low surface ...

Heterogeneous photocatalytic click chemistry
(American Chemical Society, 2016-10)
Copper-doped semiconductors are designed to photoassist the alkyne-azide cycloaddition catalysis by Cu(I). Upon irradiation, injection of electrons from the semiconductor into copper oxide nanostructures produces the ...
Copper nanoparticles in click chemistry: an alternative catalytic system for the cycloaddition of terminal alkynes and azides
(Pergamon-Elsevier Science Ltd, 2009-03)
Readily prepared copper nanoparticles have been found to effectively catalyse the 1,3-dipolar cycloaddition of a variety of azides and alkynes furnishing the corresponding 1,2,3-triazoles in excellent yields. Both the ...
Exploring the functional space of thiiranes as gelatinase inhibitors using click chemistry
(Arkat USA, 2011-02)
A series of 4-[(triazolyl)methoxy]phenyl analogs of the phenoxyphenyl-substituted thiirane SB-3CT 1 was evaluated for its ability to inhibit gelatinases, members of the matrix metalloproteinase family of enzymes. The ...
