Accurate methods for assessing food freshness through colorimetric pH response play a critical role in determining food spoilage and ensuring food quality standards. This study introduces a novel unlabeled DNA sequence, poly-dA, designed to exploit the colorimetric properties of both the single strand and the fold-back A-motif structure in conjunction with gold nanoparticles (AuNPs) under varying pH conditions. When exposed to storage temperatures of 4 °C and 25 °C, the color variations in the AuNP solution, influenced by pH level changes in mutton and sea bass samples' different storage periods, are easily discernible to the naked eye within a minute.

Department of Flexible Sensing Technology, Institute of Chemical Engineering, Guangdong Academy of Sciences, Guangzhou 510665, China.
The global solar market is booming with a rapid growth in installed integrated devices, while photovoltaic (PV) systems are suffering from waste heat, which causes the decline of the photovoltaic conversion efficiency (PCE). This study presents the seamless integration of the ionic thermoelectric generator (iTEG) layer with traditional PV modules, facilitating the exploitation of waste heat and augmenting the overall power output. Experimental results validate the effectiveness of the iTEG, demonstrating substantial power generation and a consistent energy output.

December 2024
Institute of Computing Technologies, China Academy of Railway Sciences Corporation Limited, Beijing, China.
In order to improve the operation efficiency and market competitiveness, how to optimize the ticket pricing strategy of high-speed railway to match the dynamic supply-demand relationship was an urgent problem to be studied. Taking differentiated passenger demand and supply trains as the research object, the space-time service network based on train timetable was constructed. The generalized cost formula and travel utility formula of passenger travel were proposed, which contained economy, rapidity, convenience, comfort, and route correlation cost.
