“…S. portulacastrum is a cosmopolitan species often found on marine shorelines in the tropics and subtropics (Lonard and Judd, 1997;Ramani et al, 2006). This halophyte is easily distributed via sea currents and grows from washed up vegetative fragments (Lonard and Judd, 1997). Since S. portulacastrum tolerates salinity as well as toxic metals, it is of growing interest for the phytoremediation of contaminated soil (Patil et al, 2012).…”

“…4, the elastic modulus of parenchyma was calculated for each petiole. Taking P into account as the mean value of turgor measured at z = 0.4 and z = 0.8, and using the measured cell diameter d c = 75.70 µm, measured cell wall thickness t cw = 1.00 µm, Poisson's ratio ν = 0.27 (Konrad et al, 2013) and elastic modulus of cell walls E cw = 5.00 MPa (Milani et al, 2011), an elastic modulus of 1.57 ± 0.28 MPa for the parenchyma in petioles of C. bicolor was calculated.…”

• Premise of the study: Cell turgor plays an important role in the mechanical stability of herbaceous plants. This study on petioles of Caladium bicolor 'Candyland' analyzes the correlation between fl exural rigidity and cell turgor. The results offer new insights into the underlying form-structure-function relationship and the dependency of mechanical properties from water availability.• Methods: Bending modulus E of petioles is calculated from two-point bending tests, taking into account the tapering mode. The corresponding turgor of parenchyma cells during wilting is investigated by pressure probe tests.• Key results: Wilting petioles show highly signifi cant lower values of E than petioles with suffi cient water supply. These differences are also found when comparing well-watered petioles to drought-stressed petioles having parenchyma turgor values in the same range. These results indicate an additional mechanical system sensitive to drought stress. On the basis of analyses of the contribution of different petiolar tissues toward the axial second moment of area and by using experimentally determined and literature values of E for the different tissues, we were able to (1) recalculate E of the intact petiole and to compare it with experimental data and (2) quantitatively estimate the importance of the different tissues for fl exural rigidity and E of the petiole.• Conclusions: Our results show that the decrease in fl exural rigidity of petioles of Caladium bicolor 'Candyland' during wilting results from (1) a water-loss-induced decrease in mechanical effi ciency of collenchyma fi bers and (2) turgor loss of parenchyma cells.

“…This effect is attributed to the fact that the stored energy in the filaments can be used to close a puncture-type failure locally. Similarly, residual stressbased mechanisms have been cited as responsible for wound closure in tissue [55][56][57].…”

Topologically interlocked material (TIM) systems are load-carrying assemblies of unit elements interacting by contact and friction. TIM assemblies have emerged as a class of architectured materials with mechanical properties not ordinarily found in monolithic solids. These properties include, but are not limited to, high damage tolerance, damage confinement, adaptability, and multifunctionality. The review paper provides an overview of recent research findings on TIM manufacturing and TIM mechanics. We review several manufacturing approaches. Assembly manufacturing processes employ the concept of scaffold as a unifying theme. Scaffolds are understood as auxiliary support structures employed in the manufacturing of TIM systems. It is demonstrated that the scaffold can take multiple forms. Alternatively, processes of segmentation are discussed and demonstrated. The review on mechanical property characteristics links the manufacturing approaches to several relevant material configurations and details recent findings on quasi-static and impact loading, and on multifunctional response.
