A novel growth-based plasmonic sensor for H2O2 determination was developed from dual-shaped silver nanostructures consisting of starch-stabilized yellow silver nanospheres (AgNSs) and citrate-capped red silver nanoprisms (AgNPrs). The unique ability of H2O2 to oxidize silver nanoparticles and reduce silver ion consequently was exploited to produce a highly sensitive and selective sensor (AgNSs/NPrs). AgNPrs were enlarged …
The admission for graduate programs in Chemistry and Green Chemistry and Sustainability for the second semester of academic year 2023 will open on August 16th, 2023. Applicants must complete the online application form before September 30th, 2023. Please see the information on registration and scholarship …
Comprehensive two-dimensional gas chromatography (GC×GC) offers high resolution and enhanced peak capacity separating complex samples, e.g. petrochemicals, essential oils, food or biological. This technique provides enhanced peak capacity and selectivity compared with that obtained from one dimensional GC. In this research, Assist. Prof. Dr. Chadin Kulsing and Dr. Nuttanee Tungkijanansin (Postdoctoral researcher) developed splitter-based non-cryogenic …
The generation of oxygen from electrolysis in gel electromembrane extraction (G-EME) causes a negative error when applied to the analysis of easily oxidized species such as nitrite. Nitrite in G-EME is oxidized by oxygen to nitrate, leading to the negative error and the impossibility of simultaneous analysis. In this work, the application of oxygen scavengers …
Hepatitis B infection has caused severe symptoms and fatalities around the world, so a simple and fast point-of-care diagnostics is in need. In this work, the research group of Professor Orawon Chailapakul developed an electrochemical sensor for simultaneous detection of hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg), common Hepatitis B biomarkers. …

Ten undescribed benzophenones, schomburginones A− J, together with 14 known analogs were isolated from the leaves of Garcinia schomburgkiana, an edible plant native to the Indochina region. The structures of the undescribed compounds were elucidated by NMR combined with HRMS spectroscopy, while their absolute configurations were determined using ECD and single-crystal X-ray diffraction analysis. The …
February 11, 2023, students of the Bachelor of Science in Applied Chemistry Program, Department of Chemistry, Chulalongkorn University conducted an online workshop on the applications of NASA Fire Information for Resource Management System (FIRMS) to 50 youth volunteers from Northern provinces of Thailand where severe air pollution is a norm during January to March every …
Geographical indication, a type of intellectual properties, plays a pivotal role in modern world trades. It is a tool that can very well sustain the value of local products. In a research led by Assoc. Prof. Dr. Thanit Praneenararat, the analysis of chemical constituents in Thai coffees was performed using paper spray mass spectrometry. This …
