Abstract ：
Lignin is continuously investigated by various techniques for valorization due to its high content of oxygencontaining functional groups. Catalytic systems employing hydrolysis-hydrogenolysis, leveraging the synergistic effect of redox metal sites and acid sites, exhibit efficient degradation of lignin. The predominance of either hydrolysis or hydrogenolysis reactions hinges upon the relative activity of acid and metal sites, as well as the intensity of the reductive atmosphere. In this study, the Pd-MoOx/TiO2 catalyst was found to primarily catalyze hydrolysis in the lignin depolymerization process, attributed to the abundance of moderate acidic sites on Pd and the redox-assisted catalysis of MoOx under inert conditions. After subjecting the reaction to 240 degrees C for 30 h, a yield of 48.22 wt% of total phenolic monomers, with 5.90 wt% consisting of diphenols, was achieved. Investigation into the conversion of 4-propylguaiacol (4-PG), a major depolymerized monomer of corncob lignin, revealed the production of ketone intermediates, a phenomenon closely linked to the unique properties of MoOx. Dehydrogenation of the propyl is a key step in initiating the reaction, and 4-PG could be almost completely transformed, accompanied by an over 97 % of 4-propylcatechol selectivity. This distinctive system lays a new theoretical groundwork for the eco-friendly valorization of lignin.

Abstract ：
To improve the comprehensive properties of polybutylene furandicarboxylate (PBF), 2,5-furandicarboxylic acid (2,5-FDCA), and aliphatic chain diol 1,8-octanediol and 1,4-butanediol were used as monomers to synthesize a series of bio-based polybutylene glycol-octanediol 2,5-furandicarboxylate (PBOF). The results showed that the chemical composition of PBOF could be controlled through the molar ratio of monomers. Compared with PBF, as the proportion of octanediol segments gradually increased, PBOF could gradually transform from semi-crystalline thermoplastic to amorphous form, and the glass transition temperature (Tg) gradually decreased. The crystallization ability reduced but a part of the crystal area was still retained. The copolyesters still has a decomposition temperature above 370 degrees C, indicating excellent thermal stability. The introduction of the octanediol segment significantly improved the tensile mechanical properties and flexibility of the POBF copolyester. These meet the requirements for the preparation of bio-based engineering plastics. The water absorption rate of PBOF showed that it may have certain degradable potential. PBOF copolyesters have potential application prospects in bio-based medical plastics and biodegradable packaging polymer materials after copolymerization modification. A series of high-value bio-based copoyesters were prepared from a kind of sustainable raw material, 2,5-furandicarboxylic acid. image

Abstract ：
The design of a highly active Cu -Co catalyst for catalytic transfer hydrogenolysis of lignin without the use of external hydrogen remains highly challenging. In this work, Cu 2 O was initially encapsulated in ZIF-67, and subsequently Cu 2 O@ZIF-67 was utilized as a precursor and sacrificial template to prepare the unique double core-shell hollow nanocage CuO@Co 3 O 4 . Co and Cu, serving as Lewis acid sites and dehydrogenation sites for the hydrogen -donor solvent isopropanol, respectively, exhibited synergistic enhancement, further increasing the catalytic activity. Under the optimal conditions of 220 degrees C, 1 MPa N 2 , and 4 h, the catalyst achieved 100 % conversion of 2-phenoxy-1-phenylethanol and 100 % yield towards cyclohexanol and ethylbenzene. Furthermore, the catalyst remained stable and reusable after 5 cycles, providing a practicable guidance for the valueadded conversion of lignin.

Abstract ：
Conventional tumor therapeutic modalities, such as radiotherapy, chemotherapy, and surgery, involve low tumor inhibition efficiency, non-targeted drug delivery, and side effects. The development of novel and practical nano-drug delivery systems (DDSs) for targeted tumor therapy has become particularly important. Among various bioactive nanoparticles, chitosan is considered a suitable candidate for drug delivery due to its non- toxicity, good biocompatibility, and biodegradability. The amino and hydroxyl groups of chitosan endow it with the diverse function of chemical modification, thereby improving its physical and biological properties to meet the requirements of advanced biomedical applications. Therefore, it is necessary to review the property and applications of chitosan-based materials in biomedicine. In this review, the characteristics of chitosan related to its applications are first introduced, and then the preparation and modification of chitosan-based nanoparticles, including the function tailoring of chitosan-modified nanoparticles, are demonstrated and discussed. Finally, the opportunities and challenges of chitosan-based nanomaterials in this emerging field are proposed from the perspective of the rational and systematic design for the biomedicine field.

Abstract ：
Glasses-free three-dimensional (3D) displays are being regarded as the key to the future of display that will redefine the display industry. Inspired by the curved screen, liquid crystal micro-lens arrays (LC MLAs) on flexible PET substrate with a radius of curvature of 5 cm was achieved. For demonstration, an integral imaging-based 2D/3D convertible display system is proposed by using the flexible LC MLAs (FLC MLAs) to switch its operation mode between 2D and 3D modes. When the FLC MLAs with an applied voltage are in the system, the prototype renders a matched 3D image and works in 3D mode. When the FLC MLAs do not have an applied voltage, the FLC MLAs are equivalent to glass, and the display system works in 2D mode. In addition, we also demonstrated that the FLC MLAs have a wider viewing angle than the flat integral imaging 3D display system. The depth of field ranges from 6.78 to 210.12 mm under low operating voltages of 3.4 to 3.1 Vrms, respectively. With its low voltage, thin structure, and adjustable focal length form factors, the developed display system can be integrated with off-the-shelf purchased flat panels, making it a promising option for portable electronics.

Abstract ：
At present, the development of cheap and efficient electrocatalytic hydrogen evolution catalyst is of great sig-nificance to the industrialization of hydrogen energy. In this work, Mo2TiC2Tx was firstly obtained by etching Mo2TiAlC2 with hydrofluoric acid (HF), and then CoS2 nanoparticles were grown on the surface of Mo2TiC2Tx to prepare CoS2@Mo2TiC2Tx catalyst by one-pot hydrothermal method. The hydrothermal vulcanization method for the preparation of CoS2@Mo2TiC2Tx electrocatalyst not only saves the experimental cost but also has higher vulcanization efficiency. Due to the synergistic effect of CoS2 and Mo2TiC2Tx, the CoS2@Mo2TiC2Tx catalyst exhibited good hydrogen evolution reaction catalytic activity in 0.5 M H2SO4; at a current density of 10 mA/cm2, the overpotential is only 132 mV, and the Tafel slope is 116 mV/dec. Besides, due to its unique morphology, CoS2@Mo2TiC2Tx still exhibits good durability after 24 h of continuous electrolysis. Therefore, this work pro-vides a possibility to realize non-precious metal electrocatalyst to replace Pt/C.
