Abstract ：
Plastics, accumulating globally as microplastics in living organisms, significantly contribute to environmental issues. Current materials like polylactic acid and commercial paper face limitations due to inadequate heat and water resistance, resulting in various practical inconveniences. This study reports a high-strength, water-resistant, recyclable, and naturally degradable pure cellulose food packaging material, which is crafted from bacterial cellulose (BC) and ethyl cellulose (EC) by a straightforward filtration and scratch coating process. The use of the EC ethanol solution eliminates the need for additional binders. Remarkably, the EC-BC pure cellulose material exhibits excellent mechanical properties (tensile strength of 195.3 ± 23.2 MPa), a stability in liquid environments (136.9 ± 24.2 MPa mechanical strength after 30 minutes of immersion in water), recyclability, natural degradability, cost-effectiveness, and non-toxicity. These attributes position binder-free hybrid designs, based on cellulose structures, as a promising solution to address environmental challenges arising from the extensive use of single-use plastics. © 2024 The Author(s)

Abstract ：
Hydrophilic macroporous sponge has been widely used in solar steam generation, catalysis, biosensing and other fields due to its high water transporting and adsorption ability. However, the synthesis step of hydrophilic sponge usually needs the assistance of a freezing process and toxic chemicals such as chemical crosslinkers or foaming agents. To solve these problems, herein, a novel and facile tactic based on the salting out effect was proposed to prepare hydrophilic amphibious open-cell macroporous sponge from the poly(vinyl alcohol) (PVA) solution. Glycerol, CaCl2 and Na3Cit were successively added into PVA solution. The sol-gel transition would occur due to the salting-out effect of Na3Cit and hydrogen bond crosslinking of glycerol. Finally, the hydrophilic PVA sponge with different shapes and sizes could be easily prepared. Moreover, this hydrophilic wet sponge could be room temperature dried into dry sponge and this dry sponge could be quickly restored to wet sponge after immersing in water due to its ultra-rapid water absorption. The microstructure and mechanical properties of PVA wet and dry sponges were studied. The PVA wet sponge showed excellent mechanical properties with a tensile strength, Young's modulus, and fracture energy of 1.51 +/- 0.01 MPa, 0.44 +/- 0.02 MPa, and 113.2 +/- 1.6 kJ m-2, respectively. The wet sponge prepared in this work has an average porosity of up to 50 mu m, and the pore structure can still be maintained during the conventional room temperature drying process. Moreover, the PVA sponge showed high stability in various aqueous media including acid, alkaline, and salt solutions. This work provided a simple and large-scale method to prepare amphibious open-cell hydrophilic PVA sponge. Hydrophilic macroporous sponge has been widely used in solar steam generation, catalysis, biosensing and other fields due to its high water transporting and adsorption ability.

Abstract ：
Sodium lignosulfonate amine (SLA) was synthesized by Mannich reaction. The lignin-modified waterborne polyurethane (WPU) with different branched structures was designed and prepared by introducing SLA as a hydrophilic chain extender. The effect of the introduction manner of SLA on the performance of WPU was systematically investigated. The results showed that the addition of 0.75 wt% SLA in an appropriate introduction manner can prepare a polyurethane dispersion with good stability and high solid content. The tensile strength of the SLA-modified WPU film was significantly improved to 37.3 MPa. The SLA-modified WPU film also exhibited high water resistance and thermal stability. Moreover, in the introduction manner of WPU-C, the adhesive properties of SLA-modified WPU adhesives were also improved, which was mainly attributed to the entanglement of long branched chains generated by SLA chain extension with other polyurethane chains and the formation of physically cross-linked networks through the interaction between functional groups. Therefore, the introduction of a small amount of sodium lignosulfonate amine in an appropriate manner can significantly improve the performance of WPU with high solid content, which provides a new way to prepare highperformance waterborne polyurethane.

Abstract ：
Oil pollution from the petroleum industry is a growing problem, especially in terms of the harm it causes to the aquatic environment, which puts humans and other aquatic life in grave danger. As immobilized carriers for the removal of diesel, thermoplastic polyurethane (TPU) nanofiber membranes and co-blended nano-hydroxyapatite modified thermoplastic polyurethane (TPU/nHA) nanofiber membranes are reasonably priced, non-toxic, and non-polluting. The adhesion and colonization of the bacterial cells to these carriers were studied using scanning electron microscopy (SEM). Gas chromatography was used to measure the bioremediation effectiveness, and the results after 3 days of remediation revealed a substantial improvement in the removal of hydrocarbons by immobilization compared to free bacteria. With an initial concentration of 3 g/L diesel, the TPU/1.5HA-bacteria system enhanced the removal of diesel the most (20.64 +/- 0.40%), followed by TPU/1HA-bacteria (17.49 +/- 0.08%), TPU/0.5HA-bacteria (11.97 +/- 0.40%), and TPU-bacteria (4.69 +/- 0.13%), in that order. Within three days, these scaffolders had completely absorbed the spilled diesel. There haven't been any studies done yet on the removal of diesel using various carriers loaded with Bacillus altitudinis LS-1. This study demonstrated that TPU-based electrostatic spinning films can be used as bio-carriers for hydrocarbon-degrading bacteria, enhancing the bioremediation of oil-contaminated water.

Abstract ：
Tungsten carbide (WC) is commonly used as a photocatalytic material for hydrogen production via water reduction. However, it is often combined with an effective photoabsorber to provide sufficient photoactivity. This is attributed to the narrow band gap of WC, which leads to an inadequate redox capability for water reduction. Notably, this limitation was overcome using a novel solid-liquid photocatalytic system that compliments bare WC photocatalysts with liquid-phase photosensitizing erythrosine B (ErB). The proposed concept eliminates the need to couple WC with photoabsorbing semiconductors, which often requires tedious procedures for the proper functionalization of photocatalytic composites. The experimental results indicated significant hydrogen production from the proposed solid-liquid photocatalytic system under irradiation with visible light (lambda=520 nm); however, only in the presence of triethanolamine (TEOA) as a sacrificial reagent. Evidently, a blank experiment with only WC and ErB under typical photoreaction conditions exhibited nearly zero photoactivity and the production of H2 was undetected. Similarly, nonactivity was observed for the photoreaction in the presence of ErB or WC in the irradiated TEOA solution. These blank experiments confirmed the significance of all three components, namely WC, ErB, and TEOA, which functioned as the photocatalyst, photoabsorber, and sacrificial reagent, respectively, for suitable H2 production in the proposed system. The effects of three critical parameters, such as pH, ErB concentration, and WC concentration, were systematically investigated. The optimum pH for H2 production was 8, with a slight variation to more basic or acidic conditions reducing the photoactivity of the system. At pH < 8, part of TEOA undergoes partial protonation, thereby losing its activity as a sacrificial reagent in the photocatalytic system. As the pH increased to > 8, the low proton concentration in the reaction medium perturbed the thermodynamic drive, leading to suppressed H2 production. The optimum ErB concentration was 1 mmol center dot L-1, and decreasing or increasing the ErB concentration from the optimal point was detrimental to H2 production. The diluted system (ErB concentration < 1 mmol center dot L-1) provided insufficient sensitizing agents, whereas the concentrated system (> 1 mmol center dot L-1 ErB) induced significant scattering effects that prevent light from penetrating into the reactive liquid phase. Conversely, the WC concentration exhibited a positive correlation with H2 production in a steady manner, and the highest H2 production measured by the system was at a WC concentration of 12 mmol center dot L-1. Under optimum conditions, 66 mu mol center dot h-1 of H2 was successfully produced, with a slightly higher apparent quantum efficiency (AQE) of 6.6% at 520 nm, which was attributed to the synergism of ErB-TEOA-WC in the proposed system. The photoelectrochemical evaluation confirmed the positive interactions between ErB, TEOA, and WC, which caused reduced impedance while improving charge utilization in the system. Consequently, an excellent H2 turnover number (TON) of 15 was achieved with negligible activity decay for at least 20 h of reaction. Density functional theory (DFT) calculations confirmed the major roles of W- and C-vacant sites in H2 production, which were attributed to their enhanced product desorption that facilitates high turnover rates during photoreactions. In conclusion, the proposed novel liquid-solid photocatalytic WC/ErB/TEOA system provides more facile photo-derived H2 energy from water, which circumvents the tedious photoabsorber coupling of metal carbide photocatalysts.
