Summary
Thermal treatments significantly alter lithium sodium niobate (LNN) ceramics. Quenching reduces interactions, while aging forms new phases, impacting lithium mobility and ordering.
Area of Science:
- Materials Science
- Solid-State Chemistry
- Lithium-ion Materials
Background:
- Lithium-based perovskites are vital for energy storage and sensing.
- Thermal treatments critically influence their functional properties.
- Understanding structural changes in lithium sodium niobate (LNN) is key.
Purpose of the Study:
- To investigate the effects of aging and quenching on LNN ceramics.
- To analyze local structure and lithium mobility.
- To correlate experimental findings with theoretical calculations.
Main Methods:
- Density Functional Theory (DFT) calculations.
- Transmission Electron Microscopy (TEM).
- Solid-state 7Li Magic Angle Spinning (MAS) Nuclear Magnetic Resonance (NMR) spectroscopy.
Main Results:
- Quenching inhibits lithium-rich phase formation and alters interactions.
- Aging induces LiNbO3 formation, restricting lithium mobility at grain boundaries.
- Multiple lithium environments and distinct structural differences were observed in aged samples.
Conclusions:
- Thermal processing, specifically aging and quenching, profoundly impacts LNN phase behavior.
- Structural modifications affect lithium ordering and mobility.
- DFT and NMR provide complementary insights into LNN's complex phase transitions.

02:54Trends in Lattice Energy: Ion Size and Charge
26.5K
An ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy of a compound is a measure of the strength of this attraction. The lattice energy (ΔHlattice) of an ionic compound is defined as the energy required to separate one mole of the solid into its component gaseous ions. For the ionic solid sodium chloride, the lattice energy is the enthalpy change of the process:

01:02¹H NMR: Interpreting Distorted and Overlapping Signals
1.5K
Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

01:27¹H NMR: Long-Range Coupling
2.6K
The coupling interactions of nuclei across four or more bonds are usually weak, with J values less than 1 Hz. While these are usually not observed in spectra, the presence of multiple bonds along the coupling pathway can result in observable long-range coupling.
In alkenes, spin information is communicated via σ–π overlap, as seen in allylic (four-bond) and homoallylic (five-bond) couplings. These coupling interactions are stronger when the σ bond is parallel to the alkene...

Many organic, inorganic, and biological molecules contain spin-half nuclei such as nitrogen-15, fluorine-19, and phosphorus-31. As a result, NMR studies of these nuclei have found extensive applications in chemical and biological research.
While fluorine-19 and phosphorous-31 have high natural abundances (100%) and positive gyromagnetic ratios, nitrogen-15 has a low natural abundance and a negative gyromagnetic ratio. However, nitrogen-15 is still preferred over nitrogen-14 (which has a...

01:08NMR Spectroscopy: Spin–Spin Coupling
3.0K
The spin state of an NMR-active nucleus can have a slight effect on its immediate electronic environment. This effect propagates through the intervening bonds and affects the electronic environments of NMR-active nuclei up to three bonds away; occasionally, even farther. This phenomenon is called spin–spin coupling or J-coupling. Coupling interactions are mutual and result in small changes in the absorption frequencies of both nuclei involved. While nuclei of the same element are involved...

01:17Chemical Shift: Internal References and Solvent Effects
1.3K
In an NMR sample, precise measurement of the absolute absorption frequencies of nuclei is difficult. A standard internal reference compound is added, and the frequency difference between the reference signal and sample signals is measured.
The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...
