Oxygen (O), hydrogen (H), carbon (C), and nitrogen (N) are the most common elements
found in organic and biological molecules. Among these four elements, oxygen occupies a …

There are many similarities between the first three elements of the Group VB. Two of these
three elements, vanadium and niobium, were discovered in 1801, and Tantalum was …

Two different procedures were used to prepare dealuminated BEA zeolite. The first
procedure realized in two steps consisted of first calcination of original tetraethylammonium …

The dealumination of BEA zeolite by treatment with concentrated nitric acid is evidenced by
X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR) spectroscopy. Two …

Nuclear magnetic resonance (NMR) spectroscopy is an analytical technique that gives
information on the local magnetic field around atomic nuclei. Since the local magnetic field …

Revealing the structure of oxide glasses at high pressure remains a fundamental yet difficult
problem in modern physical and chemical sciences. The recent advances in solid-state …

Recently, we established an experimental setup protocol to perform the population transfer
from half-integer quadrupolar spin to 1 H nuclei under fast MAS in the context of MQ …

93Nb solid-state NMR spectra of a series of inorganic niobates with Nb in different oxygen
coordination environments were measured. For all studied compounds the chemical …

Solid-state nuclear magnetic resonance (NMR) of quadrupolar nuclei has recently
undergone remarkable development of capabilities for obtaining structural and dynamic …

High isotropic resolution is essential for the structural elucidation of samples with multiple
sites. In this study, utilizing the benefits of TRAPDOR-based heteronuclear multiple quantum …
