The synthesis of orthoferrites the type La1−xCexFeO3+x/2, x = 0.00, 0.01, 0.03, 0.05, and 0.07, by applying a simple effective mechanochemical transformation from constituent oxides is presented. Physicochemical methods such as powder X-ray diffraction (XRD), transmission electron microscopy (TEM), UV–Vis spectroscopy, Brunauer–Emmett–Teller (BET) adsorption were applied to gain information abo...

Pseudo-binary electrolytes of (100 − x)Li4GeO4·xLi3VO4 (x = 0, 10, 20, 30, 40, and 50 mol %) pseudo-ternary 45Li4GeO4·45Li3VO4·10LiaMOb (M B, Si, P, S, Mo, W) with lithium superionic conductor (LISICON) type structures were prepared by mechanochemical treatment subsequent heat treatment. For the heated samples LISICON-type structure, activation energy decreased increasing Li3VO4 content, x samp...

The attachment point of the polymer chain to a force-responsive molecular unit (mechanophore) is decisive parameter determining bond scission rate and ultimately mechanochemical reaction outcome. However, such regiochemical substituent effects have not yet been investigated for 9-?-extended anthracene-maleimide Diels-Alder adducts. Here we combine three methods, namely ultrasonication, CoGEF co...

Mechanistic understanding of mechanochemical reactions is sparse and has been acquired mostly by stepwise ex situ analysis. We describe herein an unprecedented laboratory technique to monitor the course of mechanochemical transformations at the molecular level in situ and in real time by using Raman spectroscopy. The technique, in which translucent milling vessels are used that enable the colle...

the fuel cells are distinguished as generating of green allocable energy and are electrochemical devices of low environmental impact. porous nanocrystalline strontium-doped lanthanum manganite la0.8sr0.2mno3 (lsm) cathode materials were prepared by mechanochemical route in various grinding times. carbon black was employed to produce pores. the formation of lsm single phase was studied by x-ray ...

The mechanochemical N-alkylation of imide derivatives was studied. Reactions under solvent-free conditions in a ball mill gave good yields and could be put in place of the classical solution conditions. The method is general and can be applied to various imides and alkyl halides. Phthalimides prepared under ball milling conditions were used in a mechanochemical Gabriel synthesis of amines by th...

The mechanochemical kinetics of transcription elongation was examined with a combination of theoretical and experimental approaches. The predictive power of a sequence-dependent thermal ratchet model for transcription elongation was tested by establishing model parameters based solely on measurements under chemical perturbations and then directly predicting responses under mechanical perturbati...

Single-molecule experiments have been used with great success to explore the mechanochemical cycles of processive motor proteins such as kinesin-1, but it has proven difficult to apply these approaches to nonprocessive motors. Therefore, the mechanochemical cycle of kinesin-14 (ncd) is still under debate. Here, we use the readout from the collective activity of multiple motors to derive informa...

Abstract This lecture text is focused on the comparatively young field of mechanochemistry fluoride solids, considering both their mechanical activation and mechanochemical synthesis.
