Thermal transport properties of graphene aerogel as an advanced carrier for enhanced energy storage.

Leveraging graphene aerogels as carriers offers innovative avenues for achieving enhanced energy density, thermal conductivity, and stability in energy storage materials due to their unique attributes. This study investigates the thermal transport properties of composite sulfur cathode materials and phase change materials based on graphene aerogels using molecular dynamics simulation. A graphene aerogel model is established, and the effects of sulfur and octadecane content on the thermal transport properties of graphene aerogels and graphene aerogel-based composites are examined.

Thermal Transport Properties of Sulfur-Loaded Carbon-Based Nanotubes and Composite Sulfur Cathodes in Lithium-Sulfur Batteries.

The thermal management of lithium-sulfur batteries with high specific energy has become one of the critical issues for their applications. Carbon-based nanotubes are widely used to construct composite sulfur cathodes. This paper focuses on the thermal transport properties of sulfur-coated and sulfur-embedded boron carbide nanotubes (BCNTs) and carbon nanotubes (CNTs) and their composites using molecular dynamics.

Modulation of the thermal conductivity, interlayer thermal resistance, and interfacial thermal conductance of CN.

CN, a novel 2D semiconductor with orderly distributed holes and nitrogen atoms, has attracted significant attention due to its possible practical applications. This paper investigates the in-plane thermal conductivity and interlayer thermal resistance of CN and the interfacial thermal conductance of in-plane heterostructures assembled by CN and carbonized CN(C-CN) using molecular dynamics simulations. The in-plane thermal conductivities of CN monolayers along zigzag and armchair directions are 73.

State functions/quantities in thermodynamics and heat transfer.

In thermodynamics, it is essential to distinguish between state functions and process functions. The reason is that the simple compressible thermodynamic system is a bivariate-process system, and the change of internal energy, a state function, corresponds to two process functions, heat and work. Among the state functions in thermodynamics, entropy is a special one because it has to be defined through a process function, exchanged heat , and a unique factor of integration, 1/.

Advanced oxidation of hypophosphite and phosphite using a UV/H2O2 process.

The oxidation of hypophosphite and phosphite in an aqueous solution by an ultraviolet (UV)/H2O2 process was studied in this work. The reactions were performed in a lab-scale batch photoreactor. The effect of different parameters such as H2O2 dosage, H2O2 feeding mode and the initial pH of the solution on the oxidation efficiency of the process was investigated.

[An experimental study on SIS in reconstruction of tracheal defect in rabbits].

Objective: To investigate the feasibility of polypropylene mesh (PPM) coated with SIS to reconstruct tracheal defect and the efficiency of SIS in improving epithelialization of the reconstructed trachea and reducing the postoperative complications.

Methods: Twelve New Zealand white rabbits were chosen and divided randomly into 2 groups: PPM reconstruction group (n=6) and SIS-PPM reconstruction group (n=6). A tracheal full defect with a size of 1.

[Experimental studies on biocompatibility of heterogeneous demineralized bone matrix particles].

Objective: To evaluate the biocompatibility of manufactured heterogeneous demineralized bone matrix (DBM) particles and to provide basis for further experimental study and clinical application.

Methods: Heterogeneous DBM particles A (decreased and demineralized) and B (decreased, demineralized and acellular), particle size from 250 to 810 microm, and leaching liquor were made with a series of physical and chemical methods from pig limbs cortical bone. The residual calcium and phosphorus contents of bone particles were measured after decreased and demineralized.
