Powder X-ray diffraction (XRD) studies were carried out on PANalytical X’Pert Pro diffractometer equipped with Anton Paar TCU 1000 N Temperature Control Unit using Ni-filtered Cu radiation (V = 40 kV, I = 30 mA).
Transmission electron microscope images were taken using transmission electron microscopy (TEM) Philips CM-20 SuperTwin with 160 kV of accelerating voltage and 0.25 nm of optical resolution.
The hydrodynamic size of the nanoparticles was determined by dynamic light scattering (DLS), conducted in Malvern ZetaSizer at room temperature in polystyrene cuvette, using distilled water as a dispersant.
The emission spectra were measured using the 266 nm excitation line from a laser diode (LD) and a Silver-Nova Super Range TEC Spectrometer form Stellarnet (1 nm spectral resolution) as a detector. The temperature of the sample was controlled using a THMS600 heating stage from Linkam (0.1 1C temperature stability and 0.1 1C set point resolution).
Luminescence decay profiles were recorded using FLS980 Fluorescence Spectrometer from Edinburgh Instruments with μFlash lamp as an excitation source and R928P side window photomultiplier tube from Hamamatsu as a detector.

Characterization of Nanostructured Materials

Powder
diffraction studies were carried out
using a PANalytical X’Pert Pro diffractometer equipped with
an Anton Paar TCU 1000 N temperature control unit using Ni-filtered
Cu Ka radiation (V = 40 kV, I =
30 mA). Transmission electron microscopy (TEM) images were obtained
using a FEI Tecnai G2 20 X-TWIN microscope equipped with a CCD FEI
Eagle 2K camera with a high-angle annular dark field (HAADF) detector
and an electron gun with a LaB6 cathode. The FTIR spectra
were measured using a Bruker 66/s FTIR spectrometer. Raman spectra
were measured via a confocal microscope from Renishaw equipped with
a Si CCD camera for detection and 830 nm excitation line. The spectra
were taken in the range of 100–3200 cm–1 at
room temperature under a 100× objective. The spatial resolution
was lower than 1 μm.
The temperature-dependent emission
spectra were measured using 977 nm excitation lines using a OPOLLETE
355 LD OPO and NIRQuest-Ocean-Optics spectrometer. The temperature
of the sample was changed using a THMS 600 heating stage from Linkam
(0.1 °C temperature stability and 0.1 °C set point resolution).
The photoluminescence decay times and excitation spectra were obtained
using a FLS980 fluorescence spectrometer (Edinburgh Instruments) (1800
lines/mm grating blazed at 500 nm).

A precalculated amount of PA-66 ionene-nucleated PETs, PA-66-nucleated PET or PET was placed into a Linkam THMS 600 heating stage equipped with a temperature controller. The sample was held at 275 °C for 1 min while gradually melt-pressing it into a disc-shaped sample with a thickness of 40 μm and a diameter of 10 mm. Subsequently, the sample was cooled to RT at a 60 °C min−1 rate and analysed using a PANalytical Empyrean X-ray diffractometer at 40 mA and 45 kV in reflection mode using Cu Kα radiation (1.5406 Å wavelength). All samples were scanned in the 2θ scattering range of 10 to 50° at a rate of 4° min−1.

Optical Path Length Measurement of Humidity-Loaded Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
The optical path length through the sample (Δn in nm) was determined on a single-side coated slide with a Michelson interference microscope in transmission mode (Jenaval Interphako u.map, Carl Zeiss, Jena, Germany), equipped with a THMS600 heating stage (Linkam Scientific Instruments Ltd., Surrey, UK). In those measurements, the accuracy of optical path length is about 0.5 nm. Optical path length was determined directly, i.e., without further data treatment in two general types of experiments: one was conducted heating the humidity-loaded samples under constant and controlled atmosphere, the other was conducted under isothermal conditions at 30°C, 35°C, 50°C and 70°C, respectively; changing the humidity levels between dry and humid by purging with argon gas or humidified air (~80% r.h. at 24°C). The gas-flow was adjusted to 3 mL/sec, resulting in an exchange (equilibration) time of the heating stage chamber (volume 35 mL) of at least 20 seconds. The time of a single cycle was varied between 180 minutes and 40 minutes.

Photoluminescence Measurement Setup

Check if the same lab product or an alternative is used in the 5 most similar protocols
The photoluminescence measurements were performed on a homemade apparatus at Institut Lumière Matière, University of Lyon. The sample was illuminated by an EQ99X laser driven light source filtered by a Jobin Yvon Gemini 180 monochromator. The exit slit from the monochromator was then reimaged on the sample by two 100m focal length, 2 inch diameter MgF2 lenses. The whole apparatus has been calibrated by means of a Newport 918D low power calibrated photodiode sensor over the range 190-1000 nm. The resolution of the system being 4 nm. The emitted light from the sample is collected by an optical fiber connected to a Jobin-Yvon TRIAX320 monochromator equipped with a cooled CCD detector. At the entrance of the monochromator different long pass filter can be chosen in order to eliminate the excitation light. The resolution of the detection system is 2 nm. Temperature control over the sample was regulated with a THMS-600 heating stage with T95-PE temperature controller from Linkam Scientific Instruments.

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.
