The resulting rapid quenching rate is favourable for producing fine particles with unstable structures (e.g. the inverse spinel structure) in thermodynamic terms.
Consequently, some of the Zn content of the starting mixture could not build into the spinel structure and left the system in the form of very fine ZnO powder through the exhaust.
Some of the Fe2O3 and all of the NiO did not build into the spinel structure.
ZnFe2O4 having the normal spinel structure is paramagnetic at room temperature.

Introduction NMR in micro detection has been widely exploited for spectrum analysis, biomedical and molecular structure detection, etc.
Conventional NMR in micro detection is generally based on principles of NMR spectroscopy which exploits chemical shift to research the presence of compounds or molecular structure [1][2][3].
It has two fluidic channels, more compact structure and higher signal to noise ratio (SNR).

Introduction Characterized by abundant and well-developed pore structure, strong adsorption and desorption capacity, and easy regeneration, activated carbon fiber (ACF) has been widely applied to environmental protection, medical service, food areas and so on, as well as getting more and more wide concern currently[1].
The reason may be that the spinning solution reacts more fully with the increase of synthetic agent volume, so does the initial fiber with relatively good net structure and compact structure of produced precursor fiber [9].
When the hydrochloric acid concentration exceeds a certain degree, reaction occurs on the surface of initial fiber at early stage of solidification, and then relatively compact solidified layer is produced to prevent carbocation from entering into initial fiber, and cause precursor fiber to form skin-core structure, with loose structure of fiber core.
So it is easy to form hollow structure after activation.

In this case, one of the anhydride groups reacts with the terminal isocyanate group to form an imide cycle when carbon dioxide is eliminated, in accordance with the chemistry of urethanes.
Polyamic acid undergoes an imidization (cyclization) reaction in solution or solid phase to produce final poly(urethane-imides), in accordance with the chemistry of polyimides.
The structure of the soft segments remained unchanged.
