Synthesis and characterisation of graphene from dry, shaded musa paradisiaca(plantain)leaves and dry, shaded tectona grandis(teak)leaves.

Graphene is fundamentally a two-dimensional material with extraordinary optical, thermal, mechanical, and electrical characteristics. It has a versatile surface chemistry and large surface area. It is a carbon nanomaterial, which comprises sp2 hybridized carbon atoms placed in a hexagonal lattice with one-atom thickness, giving it a two-dimensional ...

A Theoretical Analysis of CO2 Absorption in Sun Versus Shade Leaves

Journal of Biomechanical Engineering, 1978
A one-dimensional, steady-state, constant temperature model of diffusion and absorption of CO2 in the intercellular air spaces of a leaf is presented. The model includes two geometrically distinct regions of the leaf interior, corresponding to palisade and spongy mesophyll tissue, respectively.

[Effects of shading on photosynthetic characteristics of Pinellia ternata leaves].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2009
To study the effects of shading on photosynthetic physiology and chlorophyll fluorescence of Pinellia ternata.Plant growth, chlorophyll content, net photosynthetic rate (P(n)) and chlorophyll fluorescence in P. ternata were investigated under different shading treatments (0%, 70% and 90%) when it grew about 15 cm high.The results showed that fresh ...

Evaluation of factors causing reflectance differences between Sun and Shade Leaves

Remote Sensing of Environment, 1984
Abstract Shade and sun leaves of Valencia orange [Citrus sinensis (L.) Osbeck] were collected to evaluate comparative effects of their leaf chlorophyll concentration, water content, thickness, and mesophyll volume of air on visible light reflectance, specifically the 0.45-, 0.55-, and 0.65-μm wavelength (WLs). The reflectance at the 0.45-, 0.55-, and

THE MEAN INNER RADIUS OF SUN AND SHADE ILEX OPACA LEAVES

American Journal of Botany, 1985
The mean inner radius of thickness M, a shape measure defined as the mean of the shortest distances d to the border from all internal points Pi of an object, was applied in its dimensionless form D0M to Ilex opaca sun and shade leaves. This measure has the following attributes: 1) ubiquitous input; 2) the point function f(P) = d is always single valued;
