The Cu cluster-modified MoSeTe monolayer film and its sensing properties for C₂H₄, CH₄ and CO were simulated by first-principles, and its electronic properties and sensing properties were studied. The results show that the introduction of Cu clusters improves the gas adsorption effect, especially the adsorption effect of Cu₃-MoSeTe.

Finally, the effect of strain strength on the adsorption energy of Cu₃ structure under strain engineering is studied. The strain of different strength has little effect on the adsorption energy and will not affect the performance of gas sensing.

In the present study, Ti₃C₂ MXene nanosheets were synthesized by selectively etching the Al layers from Ti₃AlC₂ MAX phases using hydrofluoric acid (HF) under prolonged stirring. The chemiresistive type sensor configuration was prepared, where synthesized Ti3C2 nanosheets were used as active layer to detect the hydrogen (H2) gas at room temperature. The prepared samples were irradiated by 10 keV N⁺ ion at three different flounces of 1×10¹⁵, 5× 10¹⁵ and 1× 10¹⁶ ions cm⁻² using indigenously developed low energy ion beam table top accelerator. The comparative study have been done to analyse the impact of ion irradiation on skelton, surface changes, and H2 gas sensing of Ti3C2 MXene nanosheets after and before irradiation. It was observed that after irradiation, the sensor exhibited a higher and faster response, with the response magnitude increasing linearly with ion fluence.

DFT results indicated a strong interaction between decanoic acid and the graphene surface (−35.88 kJ/mol), characterized by a parallel orientation that maximizes van der Waals interactions. In contrast, menthol displayed weaker adsorption energies (−5.15 kJ/mol) and a predominantly perpendicular orientation. MD simulations revealed the formation of distinct adsorption layers, with decanoic acid enriched in the first layer and menthol in the second, while the NADES hydrogen-bonding network remained largely intact. CO₂ exhibited preferential adsorption over flue gas components (N₂, H₂O, O₂), with substantial accumulation in both the first and second interfacial layers. Approximately 50% of the CO₂ content from flue gas mixtures was retained within the structured region.
