The following chemical
reagents were used to prepare the silver cubic nanoparticles and SERS
substrates: trisodium citrate dihydrate, silver nitrate, potassium
chloride, ethylene glycol, ethanol, acetone (all of the above reagents
were from POCH S.A.), sodium sulfide (Sigma-Aldrich), polyvinylpyrrolidone
(PVP) with an average molar mass of ca. 4 × 10⁴ g/mol
(Fluka), glycerin (Chempur), ammonium fluoride (Chempur), and pyridine
(UniChem). All of the chemicals were used without further purification
or treatment. The water was purified by a Millipore Milli-Q system
and had a resistivity of ca. 18 MΩ/cm¹¹. A titanium
foil (0.25 mm-thick and 99.5% purity) from Alfa Aesar was used to
form the ATO (anodic titanium oxide) layer, and the reference was
a flat SERS substrate cut into 1 cm² round plates. Before
anodization, all the plates were cleaned ultrasonically with acetone
and ethanol, rinsed with water, and dried in air.

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

TiO₂ nanotube arrays have been fabricated by anodization of (10 cm × 10 cm), 250 µm Titanium foil (purity 99.5%; Alfa Aesar) in ethylene glycol containing 0.2 vol% H₂O and 0.3 M NH₄F at 60 V bias voltage in two-electrode electrochemical setup for 100 min at room temperature to get nanotubes with the length of 20 µm. Nanotubes were annealed at 450 °C for 6 h in pure oxygen with heating and cooling rates of 1 °C min⁻¹ to get pure anatase phase. The precise method for fabrication and characterization of self-organized TiO₂ nanotubes can be found in our previous publications^{32 (link),33 (link)}. The Wettability has been investigated utilizing Dataphysics-OCA setup by recording the contact angle of 2 µL drop on nanotube surface. TENG were fabricated from two layers and operated in vertical contact-separation mode. The static part was fabricated by attaching 2 Mil Kapton@Tape on the Aluminium tape, the contact provided directly through Aluminium tape. The moving parts are is Titanium nanotube array electrode. Electrodes had rectangular shape with the size of 3 cm × 3 cm. The current characterizations were performed using autolab potentiostat (Metrohm Autolab PGSTAT 302N) and the acquired voltages were recorded using 2 GHz Agilent digital oscilloscope. All experiments has been done by home-made atuomatic tapping instrument with the control of force and frequency of tapping.

Conversion of PbO2 to PbI2 Protocol

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

Conversion
of the as-deposited PbO₂ to PbI₂ was carried
out in a 100 mL Erlenmeyer flask with a ground-glass joint (VWR, 29/32).
Hydroiodic acid (20–300 μL, 55%, no stabilizer; Sigma-Aldrich)
was pipetted into a glass boat (l = 5 cm, w = 1 cm), and the boat was transferred into the flask.
A total of 250 mg of silica gel granules (2–6 mm; VWR Chemicals)
was spread around the boat inside the flask to absorb excess water
from the Hydroiodic acid. A substrate holder was bent from a titanium
foil (Alfa Aesar, 0.25 mm, 99.5%) and placed over the boat. The PbO₂ films were placed onto the holder facing upward. The flask
was then flushed with nitrogen (99.999%) for 2 min and sealed with
a glass stopper. A pinch clamp and high-vacuum silicone grease were
used to ensure hermetic seal. The assembly was heated in either a
stirred oil bath or an air oven and kept at 90 °C for 90 min
unless otherwise specified. After conversion, the PbI₂ films
were removed from the still hot flask.

Fabrication of Titanium Nitride Thin Films

TiNT was fabricated
on the surface
of titanium foil (0.25 mm thick, 99.5% purity; Alfa Aesar, Tianjin,
China) by anodization.^{11 (link)} The brief process
is as follows: the foil was placed in distilled water, followed by
ultrasonic cleaning in anhydrous ethanol and distilled water for 5
min to remove any contamination. Then, samples were put in mixed acid
[a solution containing 3% (v/v) 70% HNO₃ and 2% (v/v) 48%
HF] for another 5 min to remove the oxidation layer on the titanium
surface. The pretreated foil was linked to the anode of the potentiostat,
the counter electrode was made using platinum, and the electrolyte
was created using 1 M H₃PO₄ with 0.5 wt % HF
at a voltage of 20 V and room temperature (between 15 and 25 °C)
for 3 h. Eventually, after calcination at 450 °C for 3 h, samples
were cut into 1 × 1 cm² pieces.

Anodization and Characterization of Antimony Tin Oxide (ATO) Nanostructures

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

Prior to anodization, a titanium foil (99.5% in purity, 0.25 mm thick, Alfa Aesar) was polished electrochemically, and then chemically [32 (link),34 (link),35 (link)]. Nanostructured ATO layers were synthesized in an ethylene glycol-based solution containing NH₄F (0.38 wt.%) and H₂O (1.79 wt.%) in a three-step procedure carried out at a constant voltage of 40 V at 20 °C. The first and second anodizing steps lasted for 3 h. After each step, an adhesive tape was used to mechanically remove the obtained oxide layers. The third anodizing step was carried out for 10 min in a freshly prepared electrolyte. During each step, a constant stirring rate of 200 rpm was provided [36 (link)]. As-received amorphous materials were subjected to annealing in air at 400 °C for 2 h with a heating rate of 2 °C min⁻¹ using a muffle furnace (FCF 5SHM Z, Czylok, Poland) [35 (link)]. The morphology of ATO layers was characterized using a field emission scanning electron microscope (SEM, Hitachi S-4700, Japan). The diffraction patterns of ATO were registered using X-ray diffractometer Rigaku Mini Flex II with a Cu Kα radiation (1.54060 Å) at the 2θ range of 20–60°. For the analysis of diffraction patterns, the International Centre for Diffraction Data (ICDD) database was used.

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.
