For example, carbon nanotubes aerogels in the form of forests and sponges, possess characteristics of high electrical conductivity and superelasticity resulting from their tubular or fibrillar structure with high bending stiffness, however, their application in the energy-related area is limited by their...
There are four major cultivars varieties (butterhead, crisphead, loose leaf, and romaine) based on their head formation and leaf structure. Leafy types with more bitter taste varieties are reported as rich in nutrients as well as antioxidants. Tables 9.3 and 9.4 illustrate the variation of key...
Some studies have shown that urban dust pollution leads to slight changes in leaf structure [36, 37] and this conclusion has been confirmed in our research. Different from previous studies, we chose the open urban environment as the experimental environment, which is more conducive to accurately ...
Some tree species display more than one type of leaf structure, while other trees clearly display the same leaf structure throughout. Trees with especially unique leaves include ginkgo, sassafras, yellow poplar, and mulberry. Here, we explore the various classifications that foresters study when iden...

(P < 0.01). This shows that the decrease of photosynthetic rate with an increase per unit of LMA was stronger in submerged wetland plants, indicating that the effect of changed leaf structure on the photosynthesis was bigger in submerged wetland plants. In other words, the photosynthetic ...
