exploring the effect of temperature on a mechanochemical

We describe the first in situ and real-time study of a mechanochemical reaction by variable-temperature synchrotron powder X-ray diffraction. Using the dry milling synthesis of a coordination polymer as a model system, we reveal a change in reaction mechanism if temperature is increased, and a strong dependence of the reaction rate on temperature, with a ca. 6-fold increase of the rate of

probing of ni-encapsulated ferromagnetic boron nitride

Here we report the synthesis of multifunctional Ni-encapsulated boron nitride nanotubes (BNNTs), with average diameter and length measuring ∼30 nm and ∼25 μm, by a facile ball-milling–chemical vapor deposition route. The resulting BNNTs exhibit an intense blue emission peaking at ∼480 nm upon ∼365 nm excitation, and the time-resolved emission spectroscopy shows a photoluminescence
