We developed a new test strip made from nylon coated with a special liquid called a deep eutectic solvent (DES) – an eco-friendly alternative to toxic organic solvents. This strip helps detect hexavalent chromium [Cr(VI)], a cancer-causing pollutant often found in industrial wastewater. Why DES? Because it’s safer, greener, and does the job just as …
Graphene is a popular and interested nanomaterial in terms of electrical properties, so it has been applied to fabricate electrodes for modern electronic devices and sensors. In this work, Dr. Pumidech Puthongkham and Dr. Supacha Wirojsaengthong’s group explored the properties of laser-induced graphene electrode, an emerging electrode in the present decade for using in electrochemical …

Professor Dr. Sumrit Wacharasindhu developed a green synthesis method using enzymatic catalysis. We didn’t reinvent the wheel — but we did make it greener . Enzymatic reactions in water are promising, but solubility often holds them back especially for organic compounds like α-oxo ketene dithioacetals . So we switched from “on-water” to “in-water” using a biodegradable surfactant, TPGS-750-M . …

Pla-ra, a semisolid/liquid fermented fish product, has been a stable ingredient for Thai cuisine since ancient times. It is made from three main ingredients (freshwater fish, salt, and carbohydrate sources). Lately, Pla-ra’s popularity has been growing and it has become one of Thailand’s industrial products. This chapter begins with an introduction to many Thai dishes …

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 …
