Spectrophotometric Analysis of Benzoic Acid

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

The concentrations of benzoic acid in aqueous solutions were detected by spectrophotometer UV (UV-3100PC, Shimadzu, Kyoto, Japan) in the range 300–1100 nm.
The adsorption measurements were repeated three times and the values were averaged. The thermo-analytical measurements were performed on the automatic TG/DTA instrument (Shimadzu-60, Shimadzu, Kyoto, Japan) under air flow (50 cc/min with heating rate of 10 °C min⁻¹). The morphology of the products were examined on a scanning electron microscope (FEI, Hillsboro, OR, USA). The sample preparation relied on the classical method. About 10 mg of CNTs was suspended in 3 mL ethanol, and the suspension was then deposited on a carbonated Cu-Rh grid. The pH values were measured by portable pH-meter (Bicasa, Monza Brianza, Italy).

LbL films were prepared on the surface of a quartz slide (50 × 9 × 1 mm³) (Yazawa Co., Sendai, Japan), which had been cleaned in a mixture of sulfuric and chromic acids (Wako Pure Chemicals Industries, Ltd., Osaka, Japan). The quartz slide was alternately immersed in a 0.1 mg·mL⁻¹ AGA or CMC solution and a 0.1 mg·mL⁻¹ PBA-PAMAM solution for 20 min to deposit AGA/PBA-PAMAM or CMC/PBA-PAMAM films on the surface of the quartz slide. The PBA-PAMAM and polysaccharides solutions were prepared using 10 mM N-cyclohexyl-2-aminoethanesulfonate (CHES) buffer at pH 9.0, 10 mM 1-[4-(2-hydroxyethyl)-1-piperadinyl]ethanesulfonic acid] (HEPES) buffer at pH 7.0–8.0, and 10 mM 2-(N-morpholino)ethanesulfonic acid (MES) buffer at pH 6.0. All buffer solutions (Nacalai Co., Kyoto, Japan) contained 150 mM NaCl (Wako Pure Chemicals Industries, Ltd., Osaka, Japan). The quartz slide was rinsed in the working buffer for 5 min twice after each deposition. UV absorption spectra of the film-coated quartz slide were recorded in the working buffer on a UV-visible absorption spectroscope (UV-3100PC, Shimadzu, Kyoto, Japan) after each deposition of PBA-PAMAM and AGA or CMC.

UV–Vis spectra were recorded at 20 °C using Shimadzu UV-3600 and UV-3100PC spectrometers with a quartz cell having an optical length of 1 cm. XPS spectra were measured with a PHI 5000 VersaProbe (Ulvac-Phi, Inc.). Al Kα (15 kV, 25 W) radiation was used as the X-ray source. The beam was focused on a 100 μm² area. Samples were sputtered with an Ar ion gun to remove the oxidized surface prior to the measurements. The spectra were analyzed with the MultiPak software (Physical Electronics), and were standardized according to the Au 4f_7/2 peak at 84.0 eV. Background subtract, peak smoothing and fitting were used to estimate peak areas. STEM images were obtained using a transmission electron microscope (JEOL, ARM-200F) and the HAADF method. STEM samples were deposited on a super high-resolution carbon film with a Cu mesh (Okenshoji Co.). Cyclic voltammetry was performed using a BAS ALS750B analyzer. A glassy carbon disc electrode and platinum wire were used as the working and counter electrodes, respectively. An Ag⁺/Ag (0.01 M AgNO₃ in 0.1 M Bu₄NClO₄/acetonitrile) electrode was used as the reference electrode. NaPF₆ (0.05 M) was used as the electrolyte.

Cu Grid Electrode Characterization and Capacitor Sensor Fabrication

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

Scanning electron microscopy (SEM) images were obtained on a JSM-7400F scanning electron microscope (JEOL, Japan) at 10 kV. The samples were coated with a thin Pt layer before observation. The pattern heights were measured using a stylus surface profiler, Dektak XT-(ULVAC, Japan). Optical images of the surfaces were taken using a VW-9000/VW-600c digital microscope (KEYENCE, Japan). The optical transmittance of the Cu grid electrodes was measured using a UV-vis spectrometer, UV-3100PC (SHIMADZU, Japan); a baseline correction was performed using the bare PEN substrate, which was also used as a reference. For sheet resistance measurements, Au electrode pads with a gap distance of 5 mm were modified on the Cu grid electrodes by a simple sputtering deposition before the measurements. The sheet resistance of the Cu grid electrodes was measured by the four-probe method using a KB-100 (KB-esi, Germany). More than three measurements were performed for each sample, and the results were averaged. As for evaluation as a capacitor sensor, the sensor was fabricated by putting two grid electrodes together in a face to face manner as shown in the inset of Fig. 7. Capacitance data of the sensor was collected by a precision LCR meter, 4284 A (Agilent Technologies, USA) when pressure was added by an autograph, AGS-X (Shimadzu Corporation, Japan).

Evaluation of Complexation Efficiency

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

Complexation efficiency was evaluated based on the three factors: recovery yield (RY), embedding fraction (EF), and loading capacity (LC) calculated using Equations (1)–(3) as follows.

RY (%) = \frac{weight of recovered ICs (g)}{initial host material weight (g) + initial HEO weight (g)} \times 100,

EF (%) = \frac{weight of embedded HEO (g)}{initial HEO weight (g)} \times 100

LC (%) = \frac{weight of embedded HEO (g)}{weight of recovered ICs (g)} \times 100

The weight of embedded HEO was determined as follows: a calibration curve showing the correlation of the HEO concentration and its absorbance at a wavelength of 240 nm was previously constructed using an ultraviolet-visible spectrophotometer (UV-3100 PC, Shimadzu Corporation, Kyoto, Japan) according to the methodology described in our former study [28 (link)]. A total of 0.04 g ICs were extracted with 40 mL ethanol via a vortex mixer (HS120214, Heathrow Scientific, LLC, Vernon Hills, IL, USA) at 3000 r min⁻¹ for 10 min, followed by centrifugation at 1700× g for 10 min. Then, the supernatant was filtered and its absorbance at 240 nm was measured. Finally, the weight of HEO embedded in the ICs was calculated using the calibration curve.

Optical Characterization of Nd:FAP Ceramics

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

For the powder and the sintered body, the crystal structures were characterized by X-ray diffraction (XRD; Ultima IV, Rigaku, Japan), and the microstructures were examined using a field-emission scanning electron microscope (FE-SEM; JSM-6701F, JEOL, Japan). The grain size was determined from an average area per grain, counted for >300 grains in the FE-SEM micrographs under an assumption of spherical grains. The grain size was used to estimate the scattering coefficient of the Nd:FAP ceramics using the Rayleigh-Gans-Debye theory as formulated by Apetz and Bruggen^{19 (link)}.
The optical in-line transmittance spectra T(λ) of the ceramics was measured using a UV/VIS/NIR spectrometer (UV-3100PC, Shimadzu, Japan). The scattering coefficient γ(λ) was estimated under an assumption of γ = δ by using

T (λ) = {[1 - R_{av} (λ)]}^{2} \exp [- δ (λ) t],

where t is the sample thickness, R_av(λ) is the theoretical reflectance obtained from the refractive index dispersion n_av(λ) as R_av = (1 − n_av)²/(1 + n_av)². Here n_av is an average of the refractive indices of ordinary and extraordinary waves, and the dispersion can be obtained using a Sellmeier equation. For calculating the transmitted spectra in the Nd:FAP ceramics using the analysed scattering coefficient, the absorption lines by an electron transition of Nd³⁺ was ignored.

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.
