Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The temperature versus concentration phase diagrams of the n-nonyl β-glucoside/water and the n-decyl β-glucoside/water systems are presented. The micellar region of the n-nonyl β-glucoside has been studied using H NMR self-diffusion to obtain information about the micellar size. Nonspherical aggregates are formed at concentrations immediately above the cmc. Three different liquid crystalline phases are formed as the concentration of n-nonyl β-glucoside is increased, viz. a hexagonal, a bicontinuous cubic (of space group Ia3d), and a lamellar phase. H NMR self-diffusion measurements have also been performed across the phase boundary separating the micellar and the cubic regions. It was found that there is no discontinuity in the surfactant self-diffusion when crossing this phase boundary. A particular feature of the n-decyl β-glucoside is the occurrence of a phase separation into two liquid isotropic solutions in the (total) surfactant concentration interval from approximately 0.1 to 17 wt% surfactant. The dilute and concentrated solutions have been examined by means of time-resolved fluorescence quenching (TRFQ). It was found that, at the lower phase boundary, nonspherical discrete aggregates are formed, whereas at the upper phase boundary (17 wt%), the aggregates are large. At high surfactant concentration (> 65 wt%), a lamellar liquid crystalline phase is formed. The liquid crystalline phases present in the two binary phase diagrams have been characterized by small-angle X-ray scattering (SAXS). The results have been analyzed in terms of repetition distances and surfactant head-group areas. An important result from the SAXS analysis is that the head-group area is an almost invariant parameter in the different liquid crystalline phases.
