Experimental analysis on dynamics of liquid molecules adjacent to particles in nanofluids

Hashimoto, Shunsuke*; Nakajima, Kenji; Kikuchi, Tatsuya*; Kamazawa, Kazuya*; Shibata, Kaoru; Yamada, Takeshi*

Journal of Molecular Liquids, 342, p.117580_1 - 117580_8, 2021/11

Quasi-elastic neutron scattering (QENS) and pulsed-field-gradient nuclear magnetic resonance (PFGNMR) analyses of a nanofluid composed of silicon dioxide (SiO$$_{2}$$) nanoparticles and a base fluid of ethylene glycol aqueous solution were performed. The aim was to elucidate the mechanism increase in the thermal conductivity of the nanofluid above its theoretical value. The obtained experimental results indicate that SiO$$_{2}$$ particles may decrease the self-diffusion coefficient of the liquid molecules in the ethylene glycol aqueous solution because of their highly restricted motion around these nanoparticles. At a constant temperature, the thermal conductivity increases as the self-diffusion coefficient of the liquid molecules decreases in the SiO$$_{2}$$ nanofluids.

NMR chemical shifts of $$^{15}$$N-bearing graphene

Wang, X.*; Hou, Z.*; Ikeda, Takashi; Terakura, Kiyoyuki*

Journal of Physical Chemistry C, 118(25), p.13929 - 13935, 2014/06

The NMR chemical shifts of possible N-containing moieties at edges and defects of graphene are investigated by using the first-principles method. Our computations show that pyridine-like and graphite-like N are rather easily identifiable using $$^{15}$$N NMR technique, in agreement with experiment. On the other hand, pyridinium-like N is hardly distinguished from pyrrole-like one because these $$^{15}$$N nuclei give nearly overlapping signals. However, our simulations suggest that $$^{1}$$H NMR is useful to discriminate between them; The NMR chemical shift of $$^{1}$$H directly bonded with pyridinium-like and pyrrole-like N is estimated as 0.8 and 10.8 ppm, respectively. The $$^{15}$$N NMR signals for various moieties at edges we considered are found to be similar to the corresponding ones at defects except for pyridine-like nitrogens. Conversely, the $$^{15}$$N NMR chemical shifts are altered sensitively by the degree of aggregation of pyridine-like $$^{15}$$N atoms both along armchair edges and at defect sites.

Precision hfs of $$^{126}$$Cs($$T$$$$_{1/2}$$ = 1.63 m) by ABMR

The hfs separation $$Deltanu$$ of $$^{126}$$Cs($$T$$$$_{1/2} = 1.63$$ m) in the 6s $$^2$$S$$_{1/2}$$ ground state was obtained in a precision measurement near zero magnetic field by means of atomic beam magnetic resonance with laser optical pumping on-line with the CERN-PSB-ISOLDE mass separator. The result, $$Deltanu = 3629.514(0.001)$$ MHz, corrects significantly a previous published value from a high-field experiment. With our result, the precision of the nuclear magnetic moment, $$mu(^{126}$$Cs)$$sim 0.776 mu_N$$, is now limited by the influence of extended nuclear structure on the hfs (the Bohr-Weisskopf effect).
