Characterization of CO₂-Responsive Organogel

The SEM images were determined from a field emission scanning electron microscope (JMS-6700F, JEOL) operated at 5.0 or 10.0 keV. The SEM samples were prepared by spreading the gel (consisting of NAP-chol 1 at 4 mg/ml in DMSO) on a glass sheet and drying at room temperature under vacuum for 24 h. The resulting xerogel was sputter-coated with 5 nm platinum in a Cressington 328 coating unit, at 40 mA. Transmission electron microscopy (TEM) images were obtained on a JEM-2100F TEM instrument operating at an acceleration voltage of 200 kV. TEM samples were prepared by depositing several drops of the diluted gel mixture onto standard carbon-coated copper grid, followed by drying under vacuum at ambient temperature for 24 h. For the CO₂-induced reformed gel, the solvent was volatilized at ambient temperature under atmospheric pressure for 1 week.

Characterization of Au NRs@TiO2 SERS Substrate

Check if the same lab product or an alternative is used in the 5 most similar protocols

The ultraviolet−visible (UV−Vis) absorption spectra of Au NRs and Au NRs@TiO₂ were recorded with a Multiskan spectrum microplate spectrophotometer (Thermo Fisher, Shanghai, China). The size and morphology of Au NRs and Au NRs@TiO₂ were inspected using transmission electron microscopy (TEM) TecnaiG2 F20 (FEI, OR, USA). The scanning electron microscopy (SEM) images of the Au NRs@TiO₂ SERS substrate were recorded by JMS-6700F (JEOL, Beijing, China). The SERS analysis was measured with an inVia micro-Raman spectrometer (Renishaw, UK). A laser power of 10 mW (output of the laser) under 633 nm was collected through a 50x objective, and the exposure time was 10 s.

To investigate the effect of HWE and UAE on the microstructure of materials, Scanning Electron Microscopy (SEM) was used to reveal the shape and surface characteristics of samples after extraction [16 (link)]. Dried samples (raw material, residues treated by UAE and HWE) of Auricularia cornea var. Li. were fixed on a specimen holder with the help of doubled-sided adhesive tapes and then sputtered with gold powder. Microstructure was obtained using a Scanning Electron Microscope (JMS-6700F, JEOL Co., Tokyo, Japan) at a 10 kV acceleration voltage.

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.
