51V NMR studies on CaV2O4 single crystals and 17O NMR studies on 17O-enriched powder samples are reported. The temperature dependences of the 17O NMR linewidth and nuclear spin-lattice relaxation rate give strong evidence for a long-range antiferromagnetic transition at TN=78 K in the powder. Magnetic susceptibility measurements show that TN=69 K in the crystals. A zero-field 51V NMR signal was...

We report $^{121/123}$Sb nuclear quadrupole resonance (NQR) and $^{51}$V magnetic (NMR) measurements on kagome metal CsV$_3$Sb$_5$ with $T_{\rm c}=2.5$ K. Both NMR spectra NQR split after a charge density wave (CDW) transition, which demonstrates commensurate CDW state. The coexistence of the high temperature phase between $91$ K $94$ manifests that it is first order transition. At low temperat...

Most ecological management applications use wireless sensor networks (WSNs) to collect data regularly, with great temporal redundancy. As a result, significant amount of energy is used transmitting redundant data, making it tremendously problematic attain satisfactory network lifetime, which bottleneck in enduring such environmental monitoring applications. A two-vector prediction model that ba...

Rationale The precision obtained in routine isotope analysis of water (?17O, ?18O, ?2H, 17O-excess and d-excess values) using cavity ring-down spectroscopy is usually below the instrument specifications provided by manufacturer. This study aimed at reducing this discrepancy, with particular attention paid to mitigating memory effect (ME). Methods We used a Picarro L2140i analyzer coupled high-p...

With increasing aridity in many regions, dew is likely to play an increasingly important role the ecohydrological processes ecosystems, especially arid and semiarid regions. Few studies investigated of evaporation during formation how it varies under different climate settings. 17O-excess, as a new tracer, could be used extract information dynamics from natural water samples (e.g., precipitatio...

Dynamic processes in solids exhibiting structurally incommensurate phases are briefly reviewed, and the application of NMR and NQR is discussed. The unique utility of these methods, arising due to, on one hand, the microscopic resonant nature of the probe used and, on the other, the presence of periodic, though incommensurable, structure , is brought out by presenting recent results in a protot...

We report experimental evidence for the spatial variation of hole concentration x(hole) in the high T(c) superconductor La2-xSrxCuO4 ( 0.04 < or = x < or = 0.16) via 63Cu NQR using 63Cu isotope enriched samples. We demonstrate that the extent of the spatial variation of the local hole concentration Delta(x)hole is reflected on (63)1/T1 and deduce the temperature dependence. Delta(x)hole increas...
