Sustainable Retrofit of Existing Buildings: Impact Assessment of Residual Fluorocarbons through Uncertainty and Sensitivity Analyses

open access: yesEnergies, 2023
Fluorocarbons are an important category of greenhouse gas emissions, and currently, their use is prohibited due to their significant contribution to the global ozone depletion potential (ODP).

Adsorption of Fluorocarbons and Chlorocarbons by Highly Porous and Robust Fluorinated Zirconium Metal–Organic Frameworks

open access: yes, 2020
Fluorocarbons and chlorocarbons are common volatile organic compounds that pose serious risk to the environment and human health and therefore need to be effectively captured. Herein, we report a series of highly fluorinated metal–organic frameworks with

3D Liquid Crystal Framework Enclosing Dual Compartments. [PDF]

open access: yesAngew Chem Int Ed Engl
A new type of liquid crystal phase is reported, having the conjugated rod‐like molecular cores form a 3D framework of elongated octahedral cages filled alternatively with alkyl and fluoroalkyl pendant chains. The cages are held together by flexible H‐bonding hinges, making them adaptable to thermal expansion and stable in a wide temperature range.

The concentration of several perfluoroalkyl acids in serum appears to be reduced by dietary fiber

open access: yesEnvironment International, 2021
Fiber-rich food intake has been associated with lower serum concentrations of perfluoroalkyl substances (PFAS) in some studies and dietary fiber was related to lower serum PFAS in a recent study.

Synthesis of Nontoxic and Bio Based Oil and Water Repellent Polymers for Cotton Fabrics Using Stearic Acid, Succinic Acid, and Itaconic Acid

open access: yesJournal of Natural Fibers, 2022
Fluorocarbon-based oil and water repellents are considered best in textile finishing due to their excellent performance. Although, long chain fluorocarbons are effective oil and water repellents but they are toxic and being banned. Therefore, the present
