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 μm, 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. © 2024 The Royal Society of Chemistry.

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 ：
Combining molecular imprinting technology with electrostatic spinning technology, a molecularly imprinted nanofiber membrane material with memory and recognition of specific imprinted molecules is thus produced. It has the advantages of high efficiency, reusability, easy amplification, and simple operation. In this study, alkane molecularly imprinted nanofibrous membranes are prepared as a carrier for immobilize Bacillus cereus LY-1 for the degradation of diesel in oil-water system. The adsorption capacity of the molecularly imprinted material for diesel oil with n-decyl alcohol as the template molecule reach 120.25 mg g-1, the adsorption capacity of alkane molecularly imprint nanofiber membrane prepared using polyvinyl alcohol (PVA) as the membrane substrate material is 41.37 mg g-1. After 4 days, the immobilized LY-1 cells eliminate roughly 80.7% of the diesel at a starting concentration of 3 g L-1. The results show that imprinted structures in MINM enhance degradation by loaded microorganisms.

合成聚乳酸聚氨酯嵌段共聚物预聚体(PLA-b-PUP),以其作为聚乳酸(PLA)和热塑性聚氨酯(TPU)的活性相容剂，通过原位反应增容制备PLA/TPU/PLA-b-PUP超韧共混物.通过拉伸试验、冲击试验、 SEM、 FTIR、 DSC和TGA研究共混物的力学性能、热性能和增韧机理.结果表明，PLA-b-PUP中的异氰酸酯基团与PLA和TPU上的活性基团发生反应，显著改善了PLA/TPU共混物两相界面的相容性.随着PLA-b-PUP的加入量增加，共混物中PLA的玻璃化转变温度和相对结晶度逐渐降低，当PLA-b-PUP的质量分数为PLA/TPU共混物的4%时，共混材料的断裂伸长率和缺口冲击强度分别达到无相容剂时的8.12和2.73倍，表现出良好的增容增韧效果.添加PLA-b-PUP后，共混物的初始分解温度有所降低，但最快分解温度有所提高.

Abstract ：
Based on transfer printing technology, micro-LED pixels can be transferred to different types and sizes of driving substrates to realize displays with different application scenarios. To achieve a successful transfer, GaN-based micro-LEDs first need to be separated from the original epitaxial substrate. Here, micro-LED pixels (each size 25 mu m x 30 mu m) on the sapphire substrate were transferred to a flexible semiconductor wafer processing (SWP) tape that is strongly sticky by conventional laser lift-off (LLO) techniques. The pixels on the SWP tape were then transferred by using a sacrificial layer of non-crosslinked oligomeric polystyrene (PS) film onto the intermediate and rigid substrate (IRS) with weak and tunable adhesion by thiol (-SH) modification. The electrode of the micro-LED is Au metal, which forms Au-S bonds with the surface of the IRS to fix the pixels. The rigid substrate helps ensure that the pixel spacing is almost unchanged during the stamp transfer process, and the weak and tunable adhesion facilitates the pixels being picked up by the stamp. The experimental results demonstrate that the pixels can be efficiently transferred to the IRS by LLO and sacrificial layer-assistance, which will provide the possibility of achieving the further transfer of pixels to different types and sizes of driving substrates by a suitable transfer stamp. The transfer process details are discussed, which can provide insights into the transfer of micro-nano devices through polymer sacrificial layers.

Abstract ：
Rapid and efficient cleaning of oily wastewater and high viscosity crude oil spills is still a global challenge. Conventional three-dimensional porous adsorbents are ineffective for oil-water separation in harsh environment and are restricted to the low fluidity of high viscosity crude oil at room temperature. Increasing temperature can enormously improve the fluidity of viscous crude oil. Herein, the polydimethylsiloxane (PDMS) /carbon black (CB)-modified polyurethane sponge (PU) were prepared by a simple one-step dip-coating method. PDMS/ CB@PU (PCPU) exhibits high adsorption capacity to various oils and organic liquid (28.5-68.7 g/g), strong mechanical properties (500 cycles at 50%), outstanding reusability (100 cycles of adsorption and desorption) and excellent environmental stability due to the special PDMS/CB coating. The maximum surface temperature of PCPU sponge can reach 84.7 celcius under 1 sunlight irradiation. Therefore, the PCPU sponge can rapidly heat and enhance the fluidity of viscous crude oil, significantly speeding up the viscous oil recovery process with the maximum adsorption capacity of 44.7 g/g. In addition, the PCPU sponge can also combine with the vacuum pump to realize the continuous and rapid repair of viscous oil spills from the seawater surface. In consideration of its simple preparation, cost-effectiveness and high oil absorption ability, this solar-assisted self-heating adsorbent provides a new direction for large-scale cleanup and recycling of viscous crude oil spill on the seawater surface.

Abstract ：
Air-borne pollutants in particulate matter (PM) form, produced either physically during industrial processes or certain biological routes, have posed a great threat to human health. Particularly during the current COVID-19 pandemic, effective filtration of the virus is an urgent matter worldwide. In this review, we first introduce some fundamentals about PM, including its source and classification, filtration mechanisms, and evaluation parameters. Advanced filtration materials and their functions are then summarized, among which polymers and MOFs are discussed in detail together with their antibacterial performance. The discussion on the application is divided into end-of-pipe treatment and source control. Finally, we conclude this review with our prospective view on future research in this area.
