Selective separation of neodymium(III) using dual function DEHPA-menthol deep eutectic solvent

Neodymium (Nd) and dysprosium (Dy) are valuable lanthanide metals used in modern technologies, particularly in permanent magnets. However, their separation is challenging due to their similar properties. This research explores the use of di(2-ethylhexyl)phosphoric acid (DEHPA) ligand as a part of a deep eutectic solvent (DES) to rapidly enhance lanthanide extraction efficiency. The prepared DES …

Fluorescent sensors for detecting copper(II) ions and glyphosate

The research group of Professor Dr. Paitoon Rashatasakhon reports the synthesis and application of dipicolylamine-functionalized fluorene (DPFR) and fluorenone (DPFN) derivatives as fluorescent sensors for detecting copper(II) ions and glyphosate. The compounds were prepared via Sonogashira coupling reactions and characterized for their photophysical properties. Both DPFR and DPFN exhibited selective fluorescence quenching in the presence …

Hydrogel from Nata de coco for biomarker detection

Bacterial cellulose (BC) or well-known as Nata de coco is a natural material with many beneficial physical properties such as biocompatibility, hydrophilicity and high porosity. Herein this research, composite hydrogels have been developed by incorporating carboxymethyl cellulose (CMC) into BC to improve re-swelling property after drying. Gold nanoparticles (AuNPs) were embedded within the BC/CMC composite …

Molecularly Dispersed Nickel Complexes on N-doped Graphene for Electrochemical CO2 reduction

The burning of fossil fuels, deforestation, and industrial processes are releasing increasing amounts of carbon dioxide (CO2) into the atmosphere, leading to serious environmental problems such as global warming. Electrochemical CO2 conversion has emerged as a promising strategy for harnessing CO2 as a chemical feedstock to synthesize value-added chemicals (e.g., carbon monoxide, formic acid, methanol, …

Laser-induced biochar as a miniaturized sorbent for μSPE of organophosphorus pesticides from environmental waters

Micro-solid phase extraction (μSPE) has been applied for sample preparation steps in trace analysis. The development of μSPE is trending toward miniaturization through a reduction in device dimensions, a decrease in sorbent amounts, and/or an incorporation of micro-sized or nano-sized materials. Various materials, both synthetic and organic in source, have been used as sorbents. Biochar, …

Rational Design of COVID-19 Drug Leads from Cancer Therapeutics

Although the COVID-19 pandemic has eased, the virus continues to evolve. The development of new, targeted antiviral drugs remains crucial for preparedness against future outbreaks. This research began with drug repurposing screening, which revealed that lapatinib—an approved breast cancer drug—can bind to and inhibit the main protease (Mpro) of SARS-CoV-2, a key enzyme required for …

A novel environmentally friendly catalyst

The research group of Assistant Professor Dr. Panuwat Padungros introduces a new eco-friendly catalyst, N,N-didodecylammonium N,N-didodecyldithiocarbamate (AmDTC-C12C12), which self-assembles in water to form vesicles that promote chemical reactions. This system allows the synthesis of valuable compounds like 4H-chromenes and γ-nitro ketones in water, avoiding harmful organic solvents. Read More Ayodele J. Atibioke Panassilp Authai Tirayut …
