Abstract:
... Zr-based metal-organic frameworks (MOFs) have been developed in recent years to treat heavy metals, e.g. hexavalent chromium Cr⁶⁺ pollution, which damages the surrounding ecosystem and threaten human health. This kind of MOF is stable and convenient to prepare, but has the disadvantage of low adsorption capacity, limiting its wide application. To this end, a novel formic acid and amino modified MO ...

Abstract:
... PREMISE: The phenomenon called “diminishing returns” refers to a scaling relationship between lamina mass (M) vs. lamina area (A) in many species, i.e., M ∝ Aᵅ>¹, where α is the scaling exponent exceeding unity. Prior studies have focused on the scaling relationships between lamina dry mass (DM) and A, or between fresh mass (FM) and A. However, the scaling between petiole mass and M and A has seld ...
