Summary: This study investigated the effects of different proportions of pomelo peel sponge layer insoluble dietary fibre (PP-IDF) on the technological quality, structural character, and sensory evaluation of wheat dough and bread. Results indicated that the addition of PP-IDF improved the viscoelasticity of dough and reduced its freezing-thawing enthalpy. Furthermore, PP-IDF significantly enhanced the quality of bread during storage, retarding the staling process and resulting in a more heterogeneous crumb microstructure.

Summary: Two-dimensional (2D) nanomaterial-based membranes hold great promise for various applications due to their attractive properties in molecular separation and transport. However, the swelling problem of 2D membranes has hindered their performance. In this study, the insertion of flexible and hydrophilic carboxylated cellulose nanofibers (CNFs) effectively stabilized the Ti3C2Tx MXene laminar architecture, enhancing mechanical strength, fixing interlayer distance, and improving anti-swelling properties. Furthermore, the intercalation of nanocelluloses increased interlayer spacing and created open gaps for fast and selective molecular transport. When applied in antibiotics separative filtration process, the resulting membrane exhibited excellent anti-swelling properties and high selectivity of antibiotics, making it ideal for various applications.

Summary: Wearable strain sensors with conductive hydrogels have great potential in electronic skins and human-machine interfaces. However, the signal transmission of conductive hydrogels is unstable due to environmental humidity and inherent material shortcomings. In this study, a novel moisture-proof conductive hydrogel was developed by incorporating dopamine-functionalized gold nanoparticles into carboxymethyl guar gum and acrylamide, showing high toughness (2.89 MJ m-3), mechanical strength (1.00 MPa), and moisture-proof sensing performance. The hydrogel-based strain sensor can accurately monitor major and subtle human movements, demonstrating good sensitivity and repeatability. Moreover, the sensor exhibits stable sensing signals even after being left for 1 hour, with no noticeable noise signal under different strains (25-300%) at 99% relative humidity. Importantly, this wearable strain sensing technology is suitable for wearable sensor devices in high humidity environments.

Summary: Novel thin film nanocomposite (TFN) membranes with flower-like MnO2 nanomaterials doped in the polyamide (PA) skin layer were prepared for efficient organic solvent nanofiltration (OSN) by interfacial polymerization (IP). The optimized TFN-0.50 membrane exhibited significantly improved OSN performance compared to pristine thin film composite (TFC) and spherical MnO2 nanoparticle-doped (TFN-S) membranes. This improved performance is attributed to the unstable interfacial polymerization and the special flower-like structure of the MnO2 nanomaterials, allowing for increased solvent contact area and additional transport channels.

Summary: Microgel-enhanced thermal-sensitive hydrogels are utilized as electrolytes to achieve active heat management, controllable energy storage, and mechanical flexibility in supercapacitors. The improved thermal sensitivity of microgel-enhanced hydrogel electrolyte allows efficient heat consumption through volume phase transition, while slowing down ion transport to weaken the energy storage process. Reversibly controlled energy storage is demonstrated by varying temperature below and above the volume phase transition temperature of the hydrogel electrolytes. The hydrogel electrolytes also provide mechanical flexibility, allowing stable charge-discharge under a bending angle from 0 to 180 degrees. Overall, this work provides a new clue for constructing intelligent hydrogel devices through elegant structure design.

Summary: A copper (II) ions-doped thin film composite (TFC-Cu) membrane with ridge-valley morphology was prepared by incorporating copper (II) ions in the aqueous phase during interfacial polymerization (IP). The ridge-valley morphology increases the contact area between the membrane and the solvent, leading to improved solvent permeability. The hydrophilicity and permeability of the membrane can be adjusted by changing the content of copper (II) ions in the aqueous phase. The modified TFC-Cu-100 membrane exhibited significantly enhanced methanol permeation performance and high dye retention level, as well as maintained good long-term organic solvent nanofiltration (OSN) performance.

Summary: With the increasing industrialization, the need for oil-water separation in oil spill accidents and wastewater treatments has become urgent. However, developing superhydrophobic materials for harsh environments and remote drives still poses a significant challenge. This study presents an alternative solution by decorating poly lauryl methacrylate (LMA) on Fe foam via the solution polymerization method. The prepared Fe foam exhibits excellent superhydrophobicity (>150 degrees) under a wide pH range (1 < pH < 12) and temperature range (-55°C to 180°C), with high separation efficiency (>99.1%), cycle stability (>50 times), and oil flux (63.7-114.6 kL m-2 h-1) against various oil/water mixtures under gravity. Additionally, remote magnetic driving enables oil harvesting both above and beneath the water.
