Samples
of Ba3–xSrxYGa2O7.5 (x = 0.15,
1.5, 2, and 2.85) were placed in fused silica tubes with a diameter
of 4 mm. A 1064 nm pulsed Nd:YAG laser (Quantel Laser, Ultra 50) was
used to generate the fundamental light, and the SHG intensity was
recorded at room temperature by a digital phosphor oscilloscope (Tektronix,
TDS3032). Intensity comparisons were made with the known SHG material
α-SiO2 under the same conditions.43 (link)

An Ar-saturated THF solution in a quartz cell (path length = 1.0 cm) was excited by a Nd:YAG laser (EKSPLA, NT342) at a wavelength of 355 nm with 20 mJ pulse−1. No positive transient signal was observed for dopant-only solutions under the measurement conditions. Time courses of the transient absorption were measured using Hamamatsu, photomultiplier tube R2949/InGaAs photodiode as detectors. The output from the detectors was recorded with a Tektronix, TDS3032 digitized oscilloscope. All experiments were performed at 298 K. The decays of the positive ΔAbs signals of Ir•+ were analyzed through a second-order kinetics model. Briefly, the molar absorbance (ε) of Ir•+ determined from the spectroelectrochemical measurement was divided by ΔAbs values at 1100 nm. The ε/ΔAbs data were plotted as a function of delay time, and fit to a linear line. The slope (in M−1 s−1) of the linear line corresponded to the kBeT value. The values were plotted as a function of −ΔGBeT, and correlated with parabolic curves calculated from the Marcus equation for adiabatic outer-sphere electron transfer, kBeT = Z exp[−(ΔGBeT + λ)2/4λkBT], in the −ΔGBeT range 0–3.0 eV. In this equation, Z, kB, and T are the collisional frequency taken as 1.0 × 1012 M−1 s−1, the Boltzmann constant, and absolute temperature (298 K), respectively.

Spectrophotometric Characterization of Chromophores

Check if the same lab product or an alternative is used in the 5 most similar protocols
The experiments were carried out by a home-constructed spectrophotometer35 (link) with some modifications. The absorption changes were evoked either by high power (2 W) laser diodes (typical wavelength of 808 nm, Roithner LaserTechnik LD808-2-TO3) of variable duration (up to 20 ms) or by a train of three saturating Xe flashes of duration 3 μs fired close (400 μs) to each other. Each Xe flashes (alone) were saturating checked by choosing no delay among the flashes. After passing through appropriate cut-off glass filters, the Xe flashes illuminated the sample in a 1 × 1 cm quartz cuvette from three different directions (see Fig. S1). A stabilized 130 W tungsten lamp was the light source of the measuring light whose wavelength and bandwidth were selected by a monochromator (Jobin–Yvon H-20 with concave holographic grating). The transmitted measuring light was detected by a photomultiplier (R928 Hamamatsu) protected from the scattered exciting light by filters. The detector was connected to a differential amplifier and to a digital oscilloscope (Tektronix TDS 3032). The time resolution of the device was limited to 50 μs. The light-induced signals of the chromophores or intact cells measured at characteristic wavelengths were always related to those at reference wavelengths.

Characterizing Pressure Profiles and Cavitation Bubbles

Check if the same lab product or an alternative is used in the 5 most similar protocols
A total of five pressure profiles were recorded inside one of the water-filled vials described below, using a polyvinylidene difluoride (PVDF) needle hydrophone (Imotec GmbH, Würselen, Germany) with a 20 ns rise time and fed into a 300 MHZ digital oscilloscope (Tektronix Inc., Beaverton, OR, USA, model TDS3032). The water level and temperature were fixed at 80 mm above F, and 25 °C, respectively. The tank was filled with tap water for both pressure measurements and shock wave exposure to the suspension-filled vials.
As an aid to select convenient delays for the tandem mode, a high-speed Motion Pro x4 (Integrated Design Tools, Inc., Pasadena, CA, USA) camera was used to record cavitation bubbles inside a sealed vial containing water and air. Images of bubble expansion and evolution were captured at 30,000 frames per second (fps) in the single-pulse mode, using a discharge voltage of 4.0, 5.0 and 6.0 kV. All reported voltages had an uncertainty of ±0.125 kV.

Photodiode-Based Detection Electronics

The detection electronics consisted of two identical channels, schematically presented in Figure 3. Each channel comprises a photodiode (BPW34, Osram Opto Semiconductors, Regensburg, Germany) followed by transimpedance amplifier (current-to-voltage converter), a low-pass filter, consisting of resistor RLP and capacitor CLP, and a buffer. The transimpedance amplifier, built using an operational amplifier (AD8627, Analog Devices, Norwood, MA, USA), converts the current I from the photodiode into voltage U according to:

where RF—transimpedance (RF = 100 kΩ). Capacitor CF improves stability of the transimpedance amplifier. The low-pass filter, with cut-off frequency of 10 kHz, filters out the broadband noise. The filter is followed by a buffer (AD8641, Analog Devices) driving a sixteen-bit data acquisition card (NI-9215, National Instruments, Austin, TX, USA) or an oscilloscope (TDS3032, Tektronix, Beaverton, OR, USA).
The detection electronics was built on a printed circuit board. It was powered by a ±12 V stabilized laboratory power supply.

Photoacoustic Measurements of Aqueous Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Photoacoustic measurements were performed using the setup described elsewhere. 22 Briefly, a Q-switched Nd:YAG laser (Surelite II, continuum, 7 ns pulse duration, 532 nm, UK) was used as the excitation source. The fluence of the laser pulses was varied using a neutral density filter, and the energy values were measured with pyroelectric energy meters (Laser Precision Corp. RJ7620 and RJP-735). The laser beam was shaped by a 1 mm diameter pinhole in front of the cuvette, so that the resolution time in our experimental set-up, t R , was ca. 800 ns. 23 The detection system consisted of a 4 mm thick  4 mm in a diameter home-made ceramic piezoelectric transducer (PZT), pressed against a cuvette side wall parallel to the laser beam direction. The detected acoustic signals were amplified, digitized by a digital oscilloscope (TDS 3032, Tektronix), and stored in a personal computer for further analysis of data. Measurements were performed by averaging the acoustic signals generated by 64 laser shots for a better signal-to-noise ratio. Aqueous solutions of the samples and a calorimetric reference (CR, New Coccine, a R = 1) were matched within 2% of absorbance values between 0.1 and 0.2 at the laser wavelength. 24 Experiments were performed under a controlled atmosphere, obtained by purging the solutions with N 2 or O 2 , for 15 min.

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.
