04-Sep-2017 | Deborah E. Crawford, Beilstein Journal of Organic Chemistry, 2017
Abstract Sonochemistry, i.e., the application of mechanical energy in the form of sound waves, has recently been recognised for its similarity to mechanochemistry and is now included under the umbrella term of mechanochemistry. Typically, due to the hypothesised cavitation mechanism, a liquid ...
11-Apr-2017 | Gabriel P. Costa; Natália Seus; Juliano A. Roehrs; Raquel G. Jacob; Ricardo F. Schumacher; Thiago Barcellos; Rafael ..., Beilstein Journal of Organic Chemistry, 2017
Abstract The use of sonochemistry is described in the organocatalytic enamine–azide [3 + 2] cycloaddition between 1,3-diketones and aryl azidophenyl selenides. These sonochemically promoted reactions were found to be amenable to a range of 1,3-diketones or aryl azidophenyl selenides, providing ...
16-Dec-2016 | Hyo Na Kim, Kenneth S. Suslick, Chemistry - A European Journal, 2016
Mechanochemistry deals with the interface between the chemical and the mechanical worlds and explores the physical and chemical changes in materials caused by an input of mechanical energy. As such, the chemical and physical effects of ultrasound, i.e., sonochemistry, are forms of ...
12-Dec-2016 | Barbosa, Ananda M.; Robles, Eduardo ; Ribeiro, Juliana S.; Lund, Rafael G.; Carreño, Neftali L. V.; Labidi, Jalel, Materials, 2016
In this work, cellulose nanocrystals (CNCs) were obtained from flax fibers by an acid hydrolysis assisted by sonochemistry in order to reduce reaction times. The cavitation inducted during hydrolysis resulted in CNC with uniform shapes, and thus further pretreatments into the cellulose are not ...
22-Feb-2016 | Mark Schaefer; Burcak Icli; Christoph Weder; Marco Lattuada; Andreas F. M. Kilbinger; Yoan C. Simon, Macromolecules, 2016
The ultrasound-induced cleavage of macromolecules has become a routine experiment in the emerging field of polymer mechanochemistry. To date, it has not been conclusively proven whether the molecular weight of a polymer or its contour length is the determining factor for chain scission upon ...
18-Dec-2015 | Temim Ouerhani; Rachel Pflieger; Warda Ben Messaoud; Sergey I. Nikitenko, Journal of Physical Chemistry B, 2015
Sonoluminescence spectra in relation with sonochemical activity of water sparged with Ar/N2 gas mixtures were systematically studied at two ultrasonic frequencies (20 and 359 kHz). At 20 kHz, solely the molecular emission of OH (A2Σ+–X2Πi) is observed in addition to a broad continuum typical for ...

Structure–activity relationships in the mechanochemistry of gem-dichlorocyclopropane (gDCC)-based polymer solutions triggered by pulsed ultrasound are reported. Insights into the flow-induced mechanochemical transformations of gDCC mechanophores into the corresponding 2,3-dichloroalkenes are ...
23-Jun-2015 | E. Lellouche; L. L. Israel; M. Bechor; S. Attal; E. Kurlander; V. A. Asher; A. Dolitzky; L. Shaham; S. Izraeli; J.-P ..., Bioconjugate Chemistry, 2015
Silencing of RNA to knock down genes is currently one of the top priorities in gene therapies for cancer. However, to become practical the obstacle of RNA delivery needs to be solved. In this study, we used innovative maghemite (γ-Fe2O3) nanoparticles, termed magnetic reagent for efficient ...
