“…Samples were ground finely with a laboratory mill (model BJ-150, Deqing Baijie Electrical Co., Ltd., Zhejiang, China) and passed through a 0.42 mm mesh screen prior to chemical analysis. The DM content was determined according to the method of AOAC (2007) ; the gross energy ( GE ) was measured according to the method of AOAC (2007) using a Parr 6400 automatic adiabatic oximeter (Parr instrument company, Moline, IL); the crude protein ( CP ) content was determined by the method of AOAC (2007) using a Kjeldahl nitrogen analyzer (model KDY-9820, Shandong Haineng Scientific Instruments Co., Ltd., Dezhou, China); the ether extract ( EE ) content was determined according to the method of AOAC (2007) using an automatic fat analyzer (model SOX-406, Shandong Haineng Scientific Instruments Co., Ltd., Dezhou, Shandong); the viscosity was determined according to the method of Furukawa et al.

“… 34 , 35 Third, no anomalous composition dependence of radiative ( k r ) and nonradiative ( k nr ) population relaxation rates of C153 in binary aqueous mixtures of TBA and ethanol has been found in earlier measurements. 34 Fourth, the composition-dependent viscosities 51 − 55 and diffusion 56 − 59 of these solutions cannot be the source for this anomalous mole fraction dependence as the composition-dependent viscosities, as shown in Figure S1 , do not indicate any extrema around x cosolvent dyn . The origin of this “dynamical anomaly” may therefore originate from a more fundamental solution aspect than the interlayer momentum transfer 60 of component particles.…”

“…Note that such a thorough composition-dependent simulation study probing the H-bond fluctuation dynamics and their connections to the experimentally detected anomalous composition dependence of solute-centered relaxation times in such alcohol–water mixtures and other aqueous amphiphilic systems has not been explored. This is notable considering that several studies 20 − 22 , 55 have already investigated mixture composition dependence hydrogen-bond dynamics and other solution properties. We have made an attempt here to establish a connection between the simulated solution structure and H-bond fluctuation dynamics and the spectral shifts and the relaxation times reported by the relevant steady-state and time-resolved fluorescence measurements.…”

We have investigated the possible connection between “dynamical anomaly” observed in time-resolved fluorescence measurements of reactive and nonreactive solute-centered relaxation dynamics in aqueous binary mixtures of different amphiphiles and the solution intra- and interspecies H-bond fluctuation dynamics. Earlier studies have connected the anomalous thermodynamic properties of binary mixtures at very low amphiphile concentrations to the structural distortion of water. This is termed as “structural anomaly.” Interestingly, the abrupt changes in the composition-dependent average rates of solute relaxation dynamics occur at amphiphile mole fractions approximately twice as large as those where structural anomalies appear. We have investigated this anomalous solution dynamical aspect by considering (water + tertiary butanol) as a model system and performed molecular dynamics simulations at several tertiary butanol (TBA) concentrations covering the extremely dilute to the moderately concentrated regimes. The “dynamical anomaly” has been followed via monitoring the composition dependence of the intra- and interspecies H-bond fluctuations and reorientational relaxations of TBA and water molecules. Solution structural aspects have been followed via examining the tetrahedral order parameter, radial and spatial distribution functions, numbers of H bonds per water and TBA molecules, and the respective populations participating in H-bond formation. Our simulations reveal abrupt changes in the H-bond fluctuations and reorientational dynamics and tetrahedral order parameter at amphiphile concentrations differing approximately by a factor of 2 and corroborates well with the steady-state and the time-resolved spectroscopic measurements. This work therefore explains, following a uniform and cogent manner, both the experimentally observed structural and dynamical anomalies in microscopic terms.

The feature size (FS) of inkjet printing is limited by nozzle size and drop spreading, which limits the realization of small optoelectronics devices and 3D microstructures. Some methods can realize small FS, but sacrifice advantages of inkjet technology. For instance, dewetting can reduce FS with all the advantages of inkjet technology kept, but is hard to print wires due to Rayleigh–Plateau instability. To solve these problems, in this paper, freezing and sublimation are introduced to direct inkjet printing wire processes. After optimizing the glycerol amount and adding tert‐butyl alcohol (TBA) in water‐based nanoparticle inks, condensed microwires of PS colloidal nanoparticles, graphene oxide (GO) nanosheets, and silver nanowires (AgNws) with small FS can be printed, respectively, by freezing, sublimation, and evaporation induced nanoparticle self‐assembly (FSE‐INS) mechanism. Using printhead with the nozzle size of 21 µm, the minimum feature size is only ≈2 µm for GO nanosheet samples. The FSE‐INS mechanism shows particle‐dimension dependent structure properties, introduces an additional particle manipulation freedom perpendicular to the substrate with sacrificial vertical solid surfaces, and exhibits great potential to realize small and novel devices and 3D structures, without sacrificing the advantages of inkjet technology.
