Composite Density Measurement by Archimedes

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

The density of the composites was measured by Archimedes’s principle using a density kit fitted on an analytical balance (AB204-S/FACT, Mettler Toledo Inc., Columbus, OH, USA). The EVA/MWCNT composite was weighted both in air and ethanol, and density was calculated from the two weights as follows:

ρ_{E V A / C N T} = \frac{m_{A}}{m_{A} - m_{0}} (ρ_{0} - ρ_{L}) + ρ_{L},

in which

m_{A}

is the weight of the sample in air,

m_{0}

is the weight of the sample in the ethanol,

ρ_{L}

is the density of air (0.0012 g/cm³) and

ρ_{0}

is the density of the ethanol at the measured temperature.
For each nanotube wt.%, at least ten determinations were performed, and the average and standard deviation were reported.

The bulk density of the PP/MWCNT nanocomposites was measured according to ISO 1183-1 using the Archimedes principle on an analytical balance (AB204-S/FACT, Mettler Toledo, Columbus, OH, USA) equipped with a kit density. The PP/MWCNT pellets were weighted both in air and ethanol, at room temperature, and the reported results are the averages of ten measurements.

Comprehensive Plant Trait Analysis

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

The following fitness parameters were analyzed: total number of leaves per plant, number of siliques per plant, number of seeds per plant, and average individual seed weight. The total number of leaves with herbivory, number of intact leaves, and percentage of leaves with herbivory were also analyzed per plant. The total number of branches per plant in the field was recorded to help estimate the mentioned parameters. One to three branches per plant were collected and brought to the lab, and the number of leaves and siliques per branch was counted. The numbers per branch were then multiplied by the total number of branches per plant in the field to estimate the total number of leaves and siliques per plant.
All the siliques from the same plant were opened, and the seeds were collected in one microcentrifuge tube. Ten random seeds from the same plant were then weighed by using a precision scale (Mettler Toledo, AB204-S/FACT). This number was then divided by 10 to estimate the average seed weight for that plant.

Coral Skeletal Growth Measurement Technique

Skeletal growth of all coral polyps was assessed by means of the buoyant weight (BW) technique (Jokiel, Maragos & Franzisket, 1978 ; Davies, 1989 (link)), using a 0.1 mg resolution balance (Mettler Toledo AB204 SFACT). An initial measurement of the BW was performed at the time when the organisms were distributed in the aquaria (T = −1), a second one when the experiment started (T = 0), and subsequent weighing was conducted every 3 to 7 months throughout the experiment: T1 (119 days from T0), T2 (221 days from T0) and T3 (433 days from T0). During these measurements, temperature and salinity of seawater were monitored continuously using a YSI-30M probe. The net BW of the corals (calculated as the total coral weight minus the weight of the coral holder) was transformed to dry weight using the density of aragonite skeleton for D. dianthus species (2.78 g/cm³; Movilla et al., 2014 (link)). Calcification rates were normalized to the skeletal weight at the beginning of the experiment (T0) and subsequently, to the beginning of each sampling period (T1–T3). Results are expressed as the increase in mg CaCO₃ g⁻¹ d⁻¹, which can be translated easily into % mass increase d⁻¹ for comparison with other published studies.

UV-Visible double beam spectrophotometer (UV 1700, Shimadzu, Japan) with 1 cm matched quartz cells, Micropipette of variable volumes (Microlit, India), and Digital balance (Denver Instrument, Germany) were used for the UV-Spectrophotometric method. The HPLC experiment was executed on WATERS HPLC system which is compiled of 515 HPLC pump, arrayed with Rheodyne injection valve with loop having 20 µl capacity. Detection was performed by WATERS 2489 UV-Visible detector. EMPOWER-2 software was used to record and process the chromatographic data. PCI analytics Ultrabath sonicator with 3.5 L capacity was used for mixing and sonication purposes. Agilent Cary 360 FT-IR spectrometer with micro lab software was used to record IR spectra of API. Analytical Balance Mettler Toledo, AB204-S/FACT was used for weighing purposes.

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.
