The widespread use of herbicides, such as 2,4-D dimethylammonium, poses significant risks to aquatic ecosystems. This study assessed the toxicological effects of 2,4-D dimethylammonium on juvenile giant freshwater prawns (Macrobrachium rosenbergii) by assessing mortality, total hemocyte count (THC), acetylcholinesterase (AChE) expression, and tissue integrity using optical coherence tomography (OCT) and histological analysis. Prawns were exposed to 0, 250, 300, 350, 400, and 450 μL/L of 2,4-D dimethylammonium for 24, 48, 72, and 96 h, and both LC values and sub-lethal effects were examined.

Nitrogen K-edge X-ray absorption (XA) spectroscopy of aqueous ammonia reveals a splitting in the main-edge, which through theoretical modeling is shown to be related to symmetry breaking in hydrogen bonding. The XA main-edge of NH is formed by a pair of degenerate core-excitations into extended molecular orbitals. In aqueous solution, these form an antibonding mixture with orbitals of the surrounding water molecules.

The formation of copper oxide and zinc oxide mixture in montmorillonite was conducted by the reaction of an aqueous dispersion of Cu/Zn exchanged montmorillonite and an aqueous solution of sodium hydroxide under hydrothermal treatment. The resulting product was characterized by X-ray diffraction, scanning and transmittance electron microscopies, as well as UV-visible and photoluminescence spectroscopies. The diffuse reflectance absorption spectra showed the absorption onsets due to copper oxide (885 nm) and zinc oxide (310 and 580 nm) in the product.

Machine Learning Assisted for Preparation of Graphene Supported Cu-Zn Catalyst for CO Hydrogenation to Methanol.

Chem Asian J

July 2025

School of Bio-Chemical Engineering and Technology, Sirindhorn International Institute of Technology, Thammasat University, Pathum Thani, 12120, Thailand.

Graphene has emerged as a promising support material for Cu-Zn catalysts in CO₂ hydrogenation to methanol due to its high surface area and potential for functionalization with heteroatoms like nitrogen and oxygen, with nitrogen believed to contribute to the reaction. In this study, we combined machine learning and data analysis with experimental work to investigate this effect. Machine learning (using a decision tree model) identified copper particle size, average pore diameter, reduction time, surface area, and metal loading content as the most impactful features for catalyst design.

Small but Mighty: A Microfluidic Biofuel Cell-Based Biosensor for the Determination of Ethanol.

Molecules

February 2025

School of Chemistry, Institute of Science, Suranaree University of Technology, 111 University Ave., Nakhon Ratchasima 30000, Thailand.

We developed a membraneless-microfluidic biofuel cell (MBFC) for the quantification of ethanol. The system employs anolyte and catholyte solutions, each containing a biocatalyst and redox mediator. The laminar flow conditions in the microfluidic chip minimize the mixing between anolyte and catholyte and obviate the need for a membrane to separate them.

In the V-bending of sheet metals using a pair of plastic punch and die manufactured by a 3D printer, the effects of two different dimensions designed with the same tool geometry on the deformation behaviors of the punch, die, and sheet were evaluated. The deformation behavior and strain distribution of the punch, die, and sheet were analyzed using a digital image correlation method. Sheets from pure aluminum to ultra-high-strength steel were bent using the two tools with different spans; one was designed on the assumption of tool steel material, and the other was designed on the assumption of plastic material.
