Li7La3Zr2O12 (LLZO) is a promising electrolyte material for all-solid-state battery due to its high ionic conductivity and good stability with metallic lithium. In this article, we studied the effect of crucibles on air by synthesizing 0.25Al doped LLZO pellets in Pt alumina crucibles, respectively. The results show that composition microstructure play important roles influencing conductivity, relative density, stability. Specifically, 0.25Al-LLZO sintered exhibit density (∼96%) (4.48 ×...
Abstract Li 7 La 3 Zr 2 O 12 ( LLZO ) has been reported to react in humid air form CO on the surface, which decreases ionic conductivity. To study reaction mechanism, 0.5‐mol Ta‐doped (0.5Ta– pellets are exposed dry (humidity ~5%) and ~80%) for 6 weeks, respectively. After exposure air, formation of pellet surface is confirmed experimentally room‐temperature conductivity found drop from 6.45×10 −4 S cm −1 3.61×10 . Whereas 0.5Ta– samples amount formed much less barely decreases. further...
Abstract 3D annealed SnO 2 /graphene sheet foams (ASGFs) are synthesized by in situ self-assembly of graphene sheets prepared mild chemical reduction. L-ascorbyl acid is used to effectively reduce the nanoparticles/graphene oxide colloidal solution and form conductive networks. The annealing treatment contributes formation Sn-O-C bonds between nanoparticles reduced sheets, which improves electrochemical performance foams. ASGF has features typical aerogels: low density (about 19 mg cm −3 ),...
In this manuscript we present a novel, shape memory aerogel/epoxy composite structure composed of reduced carbon nanotube and graphene compound aerogel as scaffold epoxy resin matrix.
The semi-open cellular structure in melamine foam–graphene oxide–carbon nanotube composites reveals enhanced acoustic absorption, moisture insulation and fire retardancy.
3D composites of layered MoS<sub>2</sub> and interconnected graphene nanoribbons (GNRs) synthesized by a facile one-pot hydrothermal method exhibit excellent cycling stability rate capacity.
The recent advancements in large language models (LLMs) have brought significant changes to the field of education, particularly generation and evaluation feedback. LLMs are transforming education by streamlining tasks like content creation, feedback generation, assessment, reducing teachers’ workload improving online efficiency. This study aimed verify consistency reliability as evaluators conducting automated evaluations using various based on five educational criteria. analysis revealed...

Chinese Four-character idioms are fixed phrases with four characters that have been used for a long time in Chinese. They language units richer meanings and equivalent grammatical functions than words. concise, easy to remember, use. Many two or more meanings. It is precisely this reason the English translation of has brought considerable difficulties. In process translating into English, it difficult be accurate, profound, complete. Therefore, variety techniques should combined...
Abstract A series of electric field sensitive copolymer P(AA‐ co ‐AAEM) gels acrylic acid (AA) with acetoacetoxy ethyl methacrylate (AAEM) were prepared by free‐radical copolymerization, N,N′ ‐methylene bisacrylamide (MBAAm) and ammounium persulfate (APS) as crosslinking agent initiator, respectively.

This paper introduces a novel unsupervised deep learning approach to address the knot placement problem in field of B-spline approximation, called neural network solvers (DNN-Solvers). In DNN-Solvers, optimal knots are obtained by training DNNs, input can be any initial and output represents desirable knots. DNN-Solvers minimize approximation errors searching for suitable parameters high-dimensional space, avoiding challenges solving nonlinear nonconvex optimization problems with traditional...
