Researchers have developed an Artificial Intelligence (AI) system that enables a four-legged robot to adapt its gait to different, unfamiliar terrain, just like a real animal, in what is believed to be a world first. 

To enhance the energy density and safety of lithium metal batteries, the research team designed a ternary composite electrolyte additive system PAFE. By leveraging the synergistic coordination between Al(EtO)₃, FEC, and PFPN, an in-situ polymerization reaction occurs at the electrode surface, forming a uniform solid electrolyte interphase. This interphase simultaneously mitigates lattice stress in the Ni-rich cathode and suppresses dendrite formation at the lithium metal anode, significantly improving cycling stability and safety under 4.7 V.

The Hong Kong University of Science and Technology (HKUST) is pleased to announce the launch of WavyOcean 2.0, an immersive digital twin platform of regional earth system. This upgraded platform deeply integrates digital technologies with innovative research in Earth system, creating the first "dynamic digital mirror" for the Guangdong-Hong Kong-Macau Greater Bay Area (GBA) and China's coastal regions. With these enhancement, WavyOcean 2.0 offers the latest data on ocean currents, marine ecology, atmospheric conditions, and the distribution of rivers and pollutants in terrestrial watersheds, along with comprehensive data analysis tools and immersive visualization interactive functions. 

A new study published in Cell on July 10 has reported the world's fastest high-resolution three-dimensional (3D) imaging technology for the entire body of small animals at subcellular resolution, enabling efficient mapping of the fine architecture of the peripheral nervous system (PNS).

In a paper published in Polymer Science & Technology, an international team of scientists

has, for the first time, introduced oligoethylene glycol side chains into A-A type polymers containing BNBP units, designing a polar side chain-functionalized organic boron polymer, PBN-OEG. The introduction of polar ethylene glycol side chains improves the miscibility between the host material and small molecule dopants, exhibiting a more efficient n-type small molecule doping level compared to the control material PBN-alkyl, which only contains alkyl side chains. Consequently, PBN-OEG possesses superior thermoelectric properties, with an optimal electrical conductivity of up to 1.95 S cm^-1 and a maximum power factor of up to 4.7 μW m^-1 K^-2. Furthermore, the oligoethylene glycol side chains promote the swelling of PBN-OEG films in aqueous electrolyte solutions, facilitating the ionic transport of hydrated cations. Therefore, PBN-OEG can be used as a channel material for organic field-effect transistors (OECTs), achieving a large volumetric capacitance (C*) of 97.7 F cm^-3 and a high figure of merit (μC*) of 2.6 F cm^-1 V^-1 s^-1. This study demonstrates the potential of n-type BNBP-based OMIEC materials in the fields of organic thermoelectric transistors (OTEs) and OECTs. This study is led by Jian Liu (Key Laboratory of Polymer Science and Technology, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022, China) and Jun Liu (Key Laboratory of Polymer Science and Technology, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022, China).

The increase in precision agriculture has promoted the development of picking robot technology, and the visual recognition system at its core is crucial for improving the level of agricultural automation.
