Valorizing Tree-Nutshell Particles as Delivery Vehicles for a Natural Herbicide

Methods and Protocols, 2023
The United States is a principal producer of tree nuts (almonds, pistachios, and walnuts), resulting in the generation of excess of tree-nutshell by-products each year, with few market outlets. A nutshell is an essential, lignocellulosic layer that protects a kernel (seed) from the environment during cultivation.

ZZE-Configuration of chromophore ß-153 in C-phycocyanin from Mastigocladus laminosus [PDF]

, 1987
The photochemistry of C-phycocyanin has been studied after denaturation in the dark. It shows an irreversible reaction which has characteristics of a Ζ,Ζ,Ε- to Z,Z,Z-isomerization of dihydrobilins. Its amplitude depends on the reaction conditions, with

Modification of natural zeolite clinoptilolite and ITS application in the adsorption of herbicides

Environmental Technology, 2022
The clinoptilolite natural zeolites (NZs) posses low herbicide adsorption capacity demanding acid-, alkali-, or salt chemical modifications that enhance its adsorption. However, this may affect the material structure and charge distribution. Alternatively, zeolites may be synthesized at a high cost and time-consuming process. Consequently, new methods,

Photoredox‐Catalyzed Synthesis of a Novel Class of Fluoroalkyl Pyrazolones

Advanced Synthesis &Catalysis, EarlyView.
A photoredox strategy enables regioselective synthesis of fluoroalkyl 2‐pyrazolin‐5‐ones via radical addition and cyclization. This mild, metal‐free method shows a broad substrate scope, operates in batch and flow systems, and offers a sustainable approach to fluorinated heterocycles with potential applications in medicinal chemistry.

Sorption of four s-triazine herbicides on natural zeolite and clay mineral materials with microporosity

Fundamental Research, 2021
Sorption is an important process that controls the fate and transport of herbicides in the soil and aquifer environment. However, sorption of these pollutants on natural microporous mineral materials has received little attention. This study investigated
