Summary: Construction of eco-benign, cost effective, and high-performance supercapacitors with improved electrolytes and hierarchical porous electrodes is necessary for effective energy storage. A gel type organic redox electrolyte made of polyvinyl alcohol (PVA)-H2SO4 and an organic redox molecule, anthraquinone (PVA-H2SO4-AQ), was used to construct a symmetric supercapacitor (SSC) with a high specific capacitance and energy density. The addition of anthraquinone to the gel electrolyte significantly improved the performance of the device, suggesting a promising approach for sustainable and eco-benign energy storage materials.

Summary: Thermally oxidized activated carbon (TOAC), acidified activated carbon (AAC), and thermally deoxygenized AC (TAC) were prepared. TOAC showed the highest oxygen content and specific surface area among the three types of activated carbon. TOAC exhibited a significantly higher capacitance than AC, AAC, and TAC, indicating the synergistic effect of anchoring oxygen and large specific surface area on capacitance performance. The oxygen content enhanced the wettability between electrode and electrolyte, while the large specific surface area facilitated ions adsorption and ionic diffusion and transport.

Summary: FOSL1 is a key player in regulating the proneural to mesenchymal transition (PMT) in glioblastoma stem cells (GSCs). It promotes the ionizing radiation-induced PMT and radioresistance of Proneural GSCs. Mechanistically, FOSL1 induces PMT by promoting UBC9-dependent CYLD SUMOylation and subsequent NF-kappa B activation. Therapeutic targeting of FOSL1 holds promise to attenuate molecular subtype switching in glioblastoma patients.

Summary: In recent years, the rapid development of robot technology has led to the emergence of various robots in different fields. Service robots, which aim to provide convenience for human beings, include guide robots that can replace manual instruction and guidance. However, existing studies often lack intelligence by providing preset guidance paths or allowing users to choose target points. To address these issues, this paper proposes a robot navigation strategy based on machine emotion. The strategy establishes the machine emotion of the guide robot based on the user's emotional state and environmental information, estimates the user's intention using machine emotion and current location information, and calculates a passable path between the target point and current position using indoor path planning and obstacle avoidance methods. The proposed strategy has been successfully tested on Pepper robot and received positive feedback from subjects.
