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 …

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, …

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, …

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 …

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 …

Cadmium and nickel in industrial wastewater are harmful to human health and the environment, and current testing methods are expensive, slow, and require laboratory equipment. To address this, the research team of Assist. Prof. Dr. Pumidech Puthongkham and Dr. Nadnudda Rodthongkum created a special conductive hydrogel made from polyaniline (a conductive polymer), cellulose nanofibers (from …
