Functionalized MXene ink enables environmentally stable printed electronics

Here, authors demonstrate the electrohydrodynamic printing of alkylated 3,4-dihydroxy-L-phenylalanine functionalized MXene (AD-MXene) ink. The AD-MXene outperforms vacuum-deposited Au and Al electrodes, providing thin film transistors with good environmental stability due to its hydrophobicity.

Unveiling pore size contributions and host-guest interactions in methane adsorption under varying pressure conditions: a semi-empirical adsorption model

A pore size–segmented adsorption model was proposed to quantify methane (CH₄) uptake in porous carbons under varying pressures (1–35 bar). By defining a contribution factor (k_x), the model revealed that pores of 0.76–1.14 nm (d_ii) showed a linear correlation with CH₄ adsorption above 20 bar. These contribution values shifted to 35, 54, and 11% at 35 bar, suggesting that effective pore sizes increase with increasing pressure. Atomistic computations validated the energetics of the adsorption mechanism and supported the decoupled contribution framework, offering design insights for advanced gas storage and separation materials.

Analyzing the acido-basicity of anodically treated carbon fibers using inverse gas chromatography at infinite dilution

The picture shows the core principle of this work, that is, the process of instantaneous interaction and separation of the probe molecule (methane is present to determine the dead time of the probe molecule) with the most active site on the anodically treated carbon fiber (CF) surface. Subcequently, the energetic changes caused by this interaction were analyzed using inverse gas chromatography at infinite dilution, thereby the surface energetic properties of modified CFs were obtained. Finally, the optimal CFs anodization condition was revealed, as described in the abstract.

3D printed graphene-based self-powered strain sensors for smart tires in autonomous vehicles

Designing efficient sensors for smart tires for autonomous vehicles remains a challenge. Here, the authors present a tire-integrated system that combines direct mask-less 3D printed strain gauges, flexible piezoelectric energy harvester for powering the sensors and secure wireless data transfer electronics, and machine learning for predictive data analysis.
