For this work, Signis SG65i SWCNTs (Sigma‐Aldrich, LOT: MKCK1004) enriched in (6,5) chirality to simplify the interpretation of SWCNT migration between the phases due to the reduced number of species. Wherever specified, HiPco (Nanointegris, Canada; LOT: HP30‐006, purified) and Signis SG76i (Sigma‐Aldrich, LOT: MKBZ1157V) SWCNTs as references were also used to investigate the ATPE mechanics. For all sorting experiments and characterization, double‐distilled water obtained from the Elix Millipore system was used.
Brij c10
Manufactured by Merck Group
Sourced in United States
Brij C10 is a non-ionic surfactant commonly used as a laboratory reagent. It is a polyoxyethylene (10) cetyl ether, with the chemical formula C₁₆H₃₃(OCH₂CH₂)₁₀OH. Brij C10 is used to solubilize and stabilize proteins and other biological molecules in aqueous solutions.

DCN was a kind gift from EVA Pharmaceutical Industries (Cairo, Egypt). Cholesterol (CH), Span 60 (sorbitan monostearate), Brij S2 (polyoxyethylene (2) stearyl ether), Brij C10 (polyoxyethylene (10) cetyl ether), and acetonitrile (HPLC grade) were purchased from Sigma Chemical Co. (St. Louis, MO). Sodium taurocholate (STC), Cremophor EL, and Cremophor RH 40 were acquired from BASF Co. (Florham Park, NJ). Methanol, chloroform, disodium hydrogen phosphate, potassium dihydrogen phosphate, and sodium chloride were purchased from El-Nasr Pharmaceutical Chemicals Co. (Abu-Zaabal, Cairo, Egypt). All other reagents were of analytical grade and were used as received.

Hexachloroplatinic acid hydrate (H2PtCl6·xH2O), polyethylene glycol hexadecyl ether (Brij®C10), (R)- and (S)-phenylethanol, acetophenone, (S)- and (R)-1-(4-bromophenyl) ethanol, isopropyl alcohol, ethyl alcohol, heptane, ammonium chloride (NH4Cl), potassium hexacyanoferrate (ii ) trihydrate (K4Fe(CN)6·3H2O), nitric acid (HNO3) and heptanethiol were obtained from the Merck Sigma-Aldrich. 4-Bromoacetophenone, and sulfuric acid (H2SO4) were purchased from the TCI and Alfa, respectively. MilliQ water (18.2 MΩ cm) was used for all experiments. All chemicals were directly employed without further purification.

Polyoxyethylene
alkyl ether (C16EO10, Brij C10) and polyoxyethylene
sorbitan monoalkylate (C16SorbEO20, Tween 40)
non-ionic surfactants and n-hexadecane (C16) were purchased from Sigma-Aldrich. All the materials were used
as received.
C16 emulsions stabilized by Brij C10
or Tween 40 were prepared by membrane emulsification with a Shirasu
porous glass membrane. Brij C10 stabilized emulsions were prepared
using a 1 wt % Brij C10 solution in water and 10 μm pore-size
membrane, resulting in ca. 33 μm droplets. Tween 40-stabilized
emulsions were prepared using a 1.5 wt % Tween 40 solution in water
and a 3 μm pore-size membrane, resulting in ca. 13 μm
droplets.
Cooling of the emulsions was realized in round capillaries
positioned
within the sample holder, so the X-ray beam passes through the top
of the sample where buoyant droplets may accumulate. The chamber temperature
was controlled by using a cryothermostat and measured close to the
emulsion location, using a calibrated thermocouple probe with an accuracy
of ±0.2 °C.
Experiments began at ambient conditions
of ca. 21 °C (294
K), which is just above the C16 melting point of 18 °C
(291 K), and therefore, oil droplets were entirely in the liquid phase.
The temperature profile for each experiment is plotted as an inlay
on the corresponding spectra figure.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
