Based on the basic idea of expanding interlayer spacing MXene, utilizing effect gallic acid-modified cellulose nanofibers for rapid moisture separation, flexible sensing and driving composite film with a perfect balance among humidity signal response mechanical properties was prepared. Inspired by stacking autumn fallen leaves, nanofibers-based films were formed self-assembly under vacuum filtration blending MXene. The enhanced (tensile strength 131.1 MPa, puncture load 0.88 N, tearing 165.55 N/mm, elongation at break 16.14 %), (the stable induced voltage 63.7 mV response/recovery time 3.2/5.1 s), (154.7° bending angle) observed. synergistic hydrogen bonds, "pinning effect" arising from side chains, hierarchical layered microstructure contributed to performance. This work exemplifies application green natural product preparing intelligent sensing, wearable devices, biomimetic robots.

The Cr-doped CeO2 nanomaterials were prepared by a simple hydrothermal method. Morphological analysis revealed that Cr doping altered the morphology and size of particles. Gas sensing tests results showed Cr/Ce-2 has highest response (Ra/Rg = 15.6 @ 10 ppm), which was 12.58 times higher than pure sensor. Furthermore, optimal operating temperature reduced from 210 °C to 170 °C. sensor also displayed outstanding repeatability gas selectivity. improved performance can be attributed its smaller grain porosity compared CeO2. In addition, oxygen vacancies played pivotal role in improving gas-sensing performance. present work provides new CeO2-based gas-sensitive material for detection n-butanol.
