Machine Learning‐Assisted Infectious Disease Detection in Low‐Income Areas: Toward Rapid Triage of Dengue and Zika Virus Using Open‐Source Hardware

Advanced Intelligent Discovery, EarlyView.
This study introduces an affordable machine learning platform for simultaneous dengue and zika detection using fluorine‐doped tin oxide thin films modified with gold nanoparticles and DNA aptamers. Designed for low‐cost, hardware‐limited devices (< $25), the model achieves 95.3% accuracy and uses only 9.4 kB of RAM, demonstrating viability for resource‐

Stereochemistry of the α-oxidation of 3-methyl-branched fatty acids in rat liver

Journal of Lipid Research, 1999
The stereochemistry of the α-oxidation of 3-methyl-branched fatty acids was studied in rat liver. R- and S-3-methylhexadecanoic acid were equally well α-oxidized in intact hepatocytes and homogenates.

Magnetic Pinecone Biochar‐Activated Peroxymonosulfate for Efficient Sulfamethoxazole Degradation: Performance, Mechanism, and Toxicity Analysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Understanding Oxide Surface Stability: Theoretical Insights From Silver Chromate

Advanced Physics Research, EarlyView.
Seven low‐index Miller surfaces, comprising 46 distinct terminations, were systematically investigated to determine their surface free energies as functions of the chemical potentials of the system constituents. The competition among these terminations gives rise to temperature‐dependent stability crossovers that dynamically reshape the surface energy ...
