A sustainable approach to synthesize phosphonated chitosan using ball milling and its application for oilfield scale management
( Royal Society of Chemistry , 2022 , Article)For many years, the oil and gas industry has strived to develop environmentally friendly organophosphorus-based scale inhibitors. The natural polymer chitosan has recently gained significant importance for various upstream ... -
A Synergistic Approach to Develop Sustainable Scale Inhibitors Combining Amino Acids and Polyphosphates
( Springer Nature , 2024 , Article)Applying conventional antiscalants, e.g., polyphosphates, may bring about environmental and health concerns, warranting the application of green compounds. This work reports the application of amino acids such as glutamic ... -
Black Titania Janus Mesoporous Nanomotor for Enhanced Tumor Penetration and Near-Infrared Light-Triggered Photodynamic Therapy
( American Chemical Society , 2024 , Article)Thanks to their excellent photoelectric characteristics to generate cytotoxic reactive oxygen species (ROS) under the light-activation process, TiO2 nanomaterials have shown significant potential in photodynamic therapy ... -
Evaluating the ecotoxicity of polymer-coated SPIONs for scale inhibition using a zebrafish embryo model
( Elsevier , 2026 , Article)Superparamagnetic iron oxide nanoparticles (SPIONs) are increasingly explored as sustainable scale inhibitors in oilfield operations, offering high efficiency, magnetic recoverability, and reduced chemical discharge. This ... -
Flexible, Linear, and Systematically Expanded Tetraphosphonate Bolaamphiphiles and Their Inhibition Performance against Calcite and Barite Scale Formation
( American Chemical Society , 2023 , Article)Oilfield scaling is one of the most prevalent water-based oilfield production problems. Chemical inhibitors are often used to combat and prevent scale deposition. The phosphonate functional group is commonly used in many ... -
Nuclear magnetic resonance spectroscopy: A comprehensive tool for analyzing liquid products in electrochemical CO2 reduction
( Elsevier , 2025 , Article)The electrochemical reduction of carbon dioxide (eCO2RR) has become a very promising pathway that can be used in the transformation of CO2 to important chemical products and, thus, is one of the mitigations of climate ... -
Phosphonated Lower-Molecular-Weight Polyethyleneimines as Oilfield Scale Inhibitors: An Experimental and Theoretical Study
( American Chemical Society , 2022 , Article)For many years, amino methylenephosphonate (-CH2-N-PO3H2)-based scale inhibitors (SIs) have been deployed for preventing various scales in the oil and gas industry, particularly for squeeze treatment applications. However, ... -
Phosphonated Polyetheramine-Coated Superparamagnetic Iron Oxide Nanoparticles for Inhibition of Oilfield Scale
( American Chemical Society , 2023 , Article)Oilfield scale is one of the significant problems in hydrocarbon production in the oil and gas industry. Many research groups have attempted to develop greener chemicals to meet environmental regulations. Magnetic nanoparticles ... -
Regiospecific Photochemical Synthesis of Methylchrysenes
( MDPI , 2023 , Article)Methylated polycyclic aromatic hydrocarbons (PAHs) are suspected to be some of the toxic compounds in crude oil towards marine life and are needed as single compounds for environmental studies. 1-, 3- and 6-methylchrysene ... -
Systematic Molecular-Size Variants in Diphosphonate Inhibitors for Oilfield Scale Management
( American Chemical Society , 2023 , Article)Organophosphorus-based scale inhibitors (SIs) have been widely used in the petroleum industry for several decades. Among them, aminomethylenephosphonates (possessing at least one −NH+-CH2-PO3H- moiety) have shown outstanding ...
