       Weedy rice is one of the most problematic weeds in rice-growing regions, particularly in Southeast Asia. Unlike other types of weeds, it is extremely difficult to distinguish weedy rice from cultivated rice directly from paddy seeds as they exhibit common morphological features. As such weed management can be a difficult, time-consuming, and …

             The research group of Assoc. Prof. Boosayarat Tomapatanaget has successfully fabricated helicene dye-encapsulated ethyl cellulose (EC@dye-NH) nanoparticles as fluorescence biosensors for specific and selective detection of long-chain aldehydes, which are significant biomarkers of lung cancer. This effective probe employed the idea of an imine formation reaction between hydrazine group …

          The carbon nitride nanocage (CNNC), which is new nanomaterial, has potential to adsorb a range of simple gasses onto either nitrogen site or carbon site. Adsorption of different gases on CNNC will have different adsorption energies. The high adsorption energies indicate the high stability of complexes that exhibit the potential …
