Mechanical Properties of Rice Culms

The outer and inner diameters of internodes were measured by the following method. We first cut off the middle of each internode, stamped their cross-sectional surface onto paper, and measured it using a ruler.
For the mechanical test of rice culms and the definitions of maximum point loading and maximum point displacement, Young’s modulus, maximum point loading (MPL), and maximum point displacement (MPD) were measured by a three-point bending test using a force tester (MCT-2150; A&D, Tokyo, Japan). Each internode was placed on two fulcrums with a 4-cm spatial interval, and the load was applied to the center of the samples. MPL and MPD were measured when the internode broke. Young’s modulus was calculated by detecting the slope between stress and strain. Stress and strain were calculated by the following equations: Stress=load×8LvDo/πDo4-Di4 Strain=displacement×6Do/Lv2 where Lv (= 4 cm) is the distance between fulcrums, Do is the outer diameter, and Di is the inner diameter.

Mechanical Properties of Composite Miniplates

Check if the same lab product or an alternative is used in the 5 most similar protocols
Five miniplates of each composite was prepared before the mechanical testing, which used an MCT-2150 A&D Company (Tokyo, Japan) universal testing machine (UTM) with a maximum force of 500 N at a crosshead speed of 10 mm/min. The tensile test that was based on the ASTM D638 Standard [52 ] was performed to determine the tensile strength (TS), Young's modulus (E), and elongation at break (EB). Meanwhile, the flexural test was conducted based on the ASTM D790 Standard [53 ] to determine the flexural strength, flexural modulus, and elongation at break. As a control, a commercial miniplate, Inion® (Inion Oy, Tampere, Finland), was also tested under similar standards.

Urushi Film Characterization by FTIR, Microscopy, and Tensile Testing

Check if the same lab product or an alternative is used in the 5 most similar protocols
Urushi films were analyzed using FTIR (Spectrum One, PerkinElmer, Inc., USA) with attenuated total reflection (ATR-FTIR). Roughness of sample surfaces was evaluated using laser microscopy (VK-100, Keyence Corporation, Japan) according to the JIS B 0601:1994 [15] . The indentation test was conducted with scanning probe microscopy (SPM, AFM5100N, Hitachi High-Technologies Corp., Japan) in force curve mode to determine the indentation stiffness of the sample surface. Sample surface stiffness (modulus of the sample surface) is given by the slope ΔF, the reaction force that a cantilever receives by tapping on the sample surface/ΔD, displacement of a cantilever by bending, of the reaction curve [16] (link). The lower the ΔF/ΔD, the softer is the sample surface [17] (link). Ten trials were performed for each sample. Dumbbell samples according to the ISO 5893-2002 standard of each film were prepared for tensile tests [18] . The tensile test was conducted using a universal material testing machine (MCT-2150, A & D Company, Japan) with a crosshead speed of 50 mm/min. The average values ± standard deviations of the elastic modulus, tensile strength, and tensile strain were evaluated using five independent specimens.

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.
