For measurements made in the helium pycnometer, activated samples were outgassed in a tube furnace (Lindberg Blue M, Thermo Fisher Scientific Inc., Waltham, MA) attached to an Edwards TIC pumping station (Edwards, West Sussex, UK) that was equipped with a nXDS6i scroll back pump (vacuum level of 10⁻² mbar, Edwards, West Sussex, UK) and an EXT-75DX turbo pump (vacuum level of 10 ⁻⁹ mbar, Edwards, West Sussex, UK). The following activation protocols were used with the porous samples.
After activation, each sample was transferred under air-free conditions from the sealed activator tube to an argon glovebox (Inert Lab Glovebox, Innovative Technology, Port Washington, NY) for storage until helium pycnometry measurements were performed. The percent mass losses for the samples after activation are 7 % mass fraction for ZSM-5, 12 % mass fraction for F400, 6 % mass fraction for MIL-53, and 0.5 % mass fraction for ZIF-8.

The swelling percentages of the scaffolds were measured using the gravimetric method. The swelling percentages were evaluated by immersing pre-weighed, in an analytical balance (ES 1255M, Precisa Gravimetrics, Dietikon, Switzerland), dry scaffold sample (

W_{d}

) of 10 × 10 mm into 4 mL of phosphate-buffered saline solution (PBS, pH 7.4) and incubated at 37 °C, in a vacuum oven (Lindberg/Blue M, Thermo Fisher Scientific, MA, USA), for 3, 7, 14, 21, and 28 days, the buffer was replaced every three days. At certain intervals, the samples were taken out and put on a filter paper to remove the excessive PBS and the weight gain of the swollen film (W_s). This process was continued until reaching the constant weight in three repeating measurements. The swelling percentage (SP) was calculated according to Equation (4) [39 (link)]:

SP % = \frac{W_{s} - W_{d}}{W_{d}} \times 100

where W_s is the weight of swollen scaffolds samples (mg), and W_d is the weight of dry scaffolds samples (mg). The measurements were repeated three times for each type of scaffold.

Annealing Study of Graphene Films.

An ink containing graphene/ethyl cellulose in ethanol/terpineol was prepared for blade-coating films. Graphene/ethyl cellulose powder (˜100 mg) was dispersed in 2 mL of 4:1 ethanol/terpineol v/v by bath sonication. This ink was blade-coated onto glass slides (VWR Micro Slides) into a 15×15 mm²film defined by a mask of scotch tape. The sample was then annealed in a tube furnace (Thermo Scientific, Lindberg Blue M). The sheet resistance of the resulting film was measured by a 4-point probe technique, employing the appropriate geometric correction factors, while the film thickness was measured by profilometry (Dektak 150 Stylus Surface Profiler). These results were used to calculate the resistivity plotted in FIG. 13A-B.

Non-Isothermal Pretreatment of Wood Flour

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

Wood flour and pretreatment liquid (dilute water, acetic or sulphuric acid) were added into reactors at 5% (w/w) solids loading. Reaction vessels with a capacity of 15 mL were stainless steel cylinders with a bolt-screw fitting on either end. Prior to closing the reactors, both fittings were sealed with polytetrafluoroethylene tape. The reactors were vortexed and preincubation at 60 °C for 60 min to ensure impregnation of the wood sample with pretreatment solvent followed. Non-isothermal pretreatment was conducted in a Lindberg Blue M laboratory gravity oven (Thermo Scientific, USA) at 180 °C. At time zero, heating in the oven began. Pressure inside the reactor was measured by attaching a 2000 psi pressure gauge (Ashcroft, USA) to a bolt-screw fitting via 30 cm of stainless steel tubing. All reactions were quenched in an ice bath.

Pyrolysis of Chromatographic Paper

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

Whatman #1 chromatographic
paper was pyrolyzed in a tubular furnace
(Lindberg/Blue M from Thermo Fisher Scientific, USA). First, strips
of paper (10.0 × 2.5 cm) were cut and placed between alumina
plates to avoid wrinkles after thermal treatment. After placing the
substrates inside the tube, a purging step with nitrogen gas (N₂) (99.99%) was conducted at 5 L min^–1 for
5 min to remove oxygen from the alumina tube. The furnace was heated
from 25 to 1000 °C at a rate of 20 °C min^–1. The furnace was kept at 1000 °C for 1h and then it was allowed
to cool at room temperature. During the pyrolysis process, we kept
N₂ at a flow rate of 20 L min^–1 flowing
through the tube to remove gases produced.
PP strips were functionalized
with PDA using the chemical route^{32 (link)} reported.
Dopamine hydrochloride (Sigma-Aldrich) was dissolved in 10 mM Tris
buffer (Sigma-Aldrich) pH 8.5 to prepare a solution of 2 mg mL^–1. PP strips were immersed in this solution for 24
h in a closed bath to minimize evaporation of the solution. After,
the lid was removed, and the solution was allowed to dry in the reservoir.
After the functionalization of PP with PDA (PP + PDA), we performed
a second stage of pyrolysis at different final temperatures of 300,
400, 500, 700, and 1000 °C using the same heating rate in all
cases.

Tin Oxide Nanowires by CVD

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

A forest of tin oxide nanowires was initially grown by chemical vapor deposition (CVD). An alumina boat filled with pure tin monoxide was placed as an evaporation source in the center of an oven (Lindberg Blue M, Thermo Fisher Scientific, Waltham, MA, USA) where the temperature is highest. Close to it (1 cm), a silicon substrate of approximately 1 × 2 cm² was placed, on which a thin gold film (thickness of approximately 5 nm) acted as a catalyst. The quartz tube was then pumped down to 10⁻² mbar and purged with high-purity argon (99.999%), repeating these two steps three times, and finally, the system was pumped down to 8 × 10⁻³ mbar. While the system was in a vacuum, the temperature was increased from room temperature (23 °C) up to 800 °C at a rate of 25 °C/min and then the oven was held at 800 °C for five minutes. At this point, an oxygen flow of 0.35 standard cubic centimeters (sccm) was injected into the system in order to start the growth of the nanowires. The growth of the nanostructures, which follows the gold-catalyzed solid liquid vapor (VLS) mechanism [29 (link)], lasted 30 min, after which the system was shut down and allowed to cool. At the end of the growth process, the sample surface showed a homogeneous white film.

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.
