To enhance the compatibility of polyhydroxybutyrate/polycaprolactone (PHB/PCL) binary blend system, a novel covalent compatibilizer, poly(methyl/amino)silsesquioxane (PMASQ) was synthesized via the base-catalyzed sol-gel method using Methyltrimethoxysilane (MTMS) and γ-Aminopropyl trimethoxysilane (APTMS). The films were prepared through the solution casting method with the blend of PHB/PCL (25:75, w/w) incorporating with various content of PMASQ (1wt%, 3wt%, 5wt%). As a result, ATR-FTIR analysis confirmed the successful synthesis of PMASQ and the subsequent grafting of PHB and PCL segments onto the PMASQ. The incorporation of 3wt% PMASQ significantly enhanced the tensile strength and elongation at break of the PHB/PCL films, demonstrating remarkable increases of 1.23 times and 6.17 times, respectively. Furthermore, the incorporation of PMASQ resulted in a reduction in crystallinity while enhancing thermal stability within the PHB/PCL blend system. An improvement in continuity was also observed in the PHB/PCL/PMASQ blends, characterized by a reduction in the size of the dispersed phase and an emergence of a homogeneous morphology. It could be concluded that PMASQ could effectively facilitate improvements in compatibility as well as physicochemical properties within this binary blend system. These findings provide theoretical support for the utilization of biodegradable biomaterials in industrial applications. © 2025, The Authors. All rights reserved.

Rational design of porous metal oxide films that serve as not only the scaffolds for light absorbers but also the transfer layer of photogenerated charges is essential for fabricating highly efficient photoanodes for photoelectrochemical (PEC) hydrogen generation. In this work, we report a facile one-step pyrolysis method which can convert Zn-based MOF to porous ZnO (m-ZnO) with rough surface and abundant oxygen vacancies (Ov). When incorporating core–shell quantum dots (QDs) as the light absorbers, the obtained photoanodes (m-ZnO@QDs) achieved outstanding PEC performance for hydrogen generation, exhibiting 1.6 times and 5.8 times higher saturated photocurrent density (Jsc) than those of conventional TiO2@QDs and ZnO@QDs photoanodes, respectively. Comprehensive optical and electrochemical measurements reveal that the rough surface of m-ZnO can significantly improve the light-harvesting capacity of corresponding photoanodes through surface-enhanced light scattering. Moreover, the Ov in m-ZnO facilitate the interfacial transfer of photogenerated electrons. Our findings indicate that the MOFs are valuable precursors for the preparation of porous films, offering a promising route to develop high-performance QDs-based PEC devices. © 2024 Institute of Process Engineering, Chinese Academy of Sciences

Succinonitrile (SN)-based plastic crystal electrolytes (PCE) show great promise for solid-state lithium-metal batteries (LMBs) because of their outstanding electrochemical properties. However, limited by the low mechanical strength of SN, SN-based PCEs are difficult to act as an independent self-supporting electrolyte films, which seriously restricts their practical application. In this study, a SN-regulated poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) porous host is proposed via a facile phase separation method as a promising strategy for addressing this issue, which enables a high-performance dual-salt SN-based PCE (named as DPCE). The as-prepared host simultaneously provides homogeneous porous network and robust mechanical support, which is convenient to accommodate DPCE evenly and increases the strength of DPCE to restrict dendrites growth. As a result, with this efficient host, the Li symmetric cell assembled with DPCE shows superior long-term stability for >1200 h at a current density of 0.1 mA cm(-2). Moreover, the assembled Li|LiFePO4 cell delivers a high-capacity retention of 99.3% after 700 cycles under 2 C at room temperature, demonstrating the promising potential for developing high-performance solid-state LMBs.

Climbing stairs has been an indispensable ability for humanoids. This paper presents a novel and practical problem: climbing stairs of varying heights. In this study, the humanoid is modeled as an inverted pendulum and set the pelvis trajectory on the vertical axis, representing the center of mass (CoM), as a quadratic function. We also use a polynomial to design the ZMP and CoM trajectory on the horizontal plane. To generate the CoM trajectory, the sliding mode controller is utilized to track the reference trajectory. To eliminate chattering of the sliding mode controller, the universal approximation property of the radial basis function (RBF) network is leveraged to approximate the switching law. Finally, simulation experiments are performed in CoppeliaSim, and the biped robot is capable of walking stably and quickly. © 2023 IEEE.

To address the challenge of achieving efficient and flexible communication between space robots and marine robots during cross-domain collaboration tasks, a hybrid communication integration architecture that combines self-organizing networks and satellite internet is proposed to overcome communication barriers. First, the fundamental technologies of self-organizing networks and satellite internet communication, along with their characteristics, are analyzed in detail. Next, the design of the hybrid communication integration architecture is elaborated, focusing on intra-cluster communication, inter-cluster communication, and cooperative communication technologies in conjunction with the ground command center. Simulation results validate the proposed architecture, demonstrating its capability to meet key performance metrics such as low communication delay, high throughput, and high reliability across various tasks. Finally, the potential optimizations and future research directions for this system are discussed, highlighting the need for improvements in real-world adaptability and scalability. © 2024 IEEE.
