Summary: Additive manufacturing allows for the design of thermoplastic components with structural support, electrical conductivity, and heat generation modulated by mechanical deformation. However, the mechanisms and interplays governing material response at the microstructural level are still uncertain. In this study, we develop an experimental method to characterize conductive filaments from mechanical, electrical, and thermal perspectives, and propose a homogenization framework to analyze the microstructure. The framework considers viscoplasticity, electrical and thermal conduction, convection, heat generation through the Joule effect, and their interdependencies. After validation, the framework is applied to optimize fabrication requirements for desired properties in final products, such as stiffness, conductivity, and sensing capabilities of filaments.

Summary: This research aimed to construct interference screws using 3D printing filaments (HA, PLA, and PCL) at different nozzle temperatures. Various tests were conducted to characterize the screws, including density tests, torsion tests, fracture analysis, and biodegradable tests. A finite element model was also established and compared with a commercial screw. The study found that the interference screw prepared in this study had the best fit for implants in terms of density within the range of cortical bone density. However, the commercial screw outperformed the interference screw in terms of torque efficiency in the clamping failure area and showed faster deterioration.

Summary: This study investigated the multiple reprocessing of a commercially available PLA conductive composite with carbon black filler for 3D printing. The effects of extrusion temperature and reprocessing steps on the rheology, morphology, thermal, and electrochemical properties of the conductive PLA 3D-printing filament were evaluated. The results showed deterioration in thermal stability and material strength, as well as an increase in melting point after initial melting. The conduction mechanism and reversibility of the redox process were also affected by the multiple processing. Furthermore, the material fluidity was too high after multiple reprocessing, which should be considered for proper application as a 3D-printed electrode material.

Summary: In this study, a novel 3D printed casing was designed and manufactured for PEM electro-ozonizers to enhance fluid dynamics and reduce ozone-scavenger interactions during electrolysis. It was found that electrogenerated scavengers, particularly cathodically formed hydrogen peroxide, limit the efficiency of electrochemical ozone production. The effects of current density, electrolyte composition, and operation pressure on efficiency were explored, with higher efficiencies achieved at higher current densities, lower concentrations of non-reacting electrolytes, and lower operation pressures. The 3D printed casing demonstrated excellent performance with ozone productions as high as 0.240 mg/(Ah cm2) and maximum current efficiencies of 5.9% under optimal conditions, showcasing the potential of 3D printing in improving electrochemical processes.

Summary: This study fabricated electrically conductive composites using the fused filament fabrication (FFF) technique and compared their properties with injection-molded samples. The results showed that the 3D-printed samples with graphene exhibited semiconductor behavior, while the injection-molded samples were insulators. The printing raster angles also influenced the electrical conductivity results. Moreover, an increase in the graphene content increased the Young's modulus of the composites.

Summary: 3D printing with polylactic acid (PLA) filament is shown to be a cheaper and more easily accessible alternative to resin printing for manufacturing PDMS molds. A method using chloroform vapor treatment is introduced to smoothen the printed PLA mold, which was successfully used to cast PDMS rings. The PDMS-glass well created with the PLA mold showed no leakage and was suitable for cell culturing, as tested with monocyte-derived dendritic cells (moDCs).

Summary: This article provides a statistical overview of studies on the thermal conductivity (TC) of nanofluids (NFs). Selected studies were identified and collected using a specific research method. The present study is divided into four sections, including most repeated keywords, articles publication year, most applied nanoparticles (NPs), and most active and pioneering countries. According to the author, this statistical research method is novel in previous studies. The results show that TC, NFs, and Al2O3 are the most repeated keywords. Additionally, a large percentage of studies were published between 2016 and 2021, with common NPs including Al2O3, CNT, and TiO2. India, Iran, China, and Malaysia are the most active and pioneering countries. The focus on TC of NFs by many great scientists indicates a growing understanding of these thermal properties.

Summary: This study discusses the mixed convection boundary layer around an isothermal solid sphere using numerical simulation. Hybrid and mono micropolar nanofluids are examined, with constant wall temperature in an MHD field. Two different types of nanoparticles, Copper oxide (CuO) and Graphite oxide (GO), are combined to create hybrid nanofluids to improve the base fluid's qualities. Sensitivity analysis reveals the impacts of the mixed convection factor, field strength, and micro-rotation factor. The results show that the effect of using nanofluids with induced micro-rotational effect is more prominent at lower angles and diminishes at higher angles. The thermal boundary layer thickness is directly proportional to the magnetic parameter, and using hybrid nanofluids instead of mono nanofluids has little effect on altering the angular velocity.

Summary: This research used molecular dynamics simulations to study the thermal performance of phase change material microcapsules containing gold nanoparticles in a nanochannel. The results show that increasing the initial temperature decreases the charging and discharging time, viscosity, and phase transition time, while increasing the heat flux and thermal conductivity. Changing the initial pressure has a minimal effect on the charging and discharging time, heat flux, and thermal conductivity. Increasing the number of metal layers in the nanochannel shells prolongs the charging and discharging time but reduces the heat flux and thermal conductivity.

Summary: A new nanocomposite scaffold was successfully synthesized in this study, which exhibited high porosity and the ability to induce bone-like apatite formation by incorporating carbon nanotubes and montmorillonite nanoparticles in a gelatin network. After soaking in simulated body fluid for 14 days, the scaffold surface successfully deposited Ca2+, CO32-, and PO43- ions. In addition, the introduction of nanoparticles significantly improved the mechanical properties of the scaffold and reduced the enzymatic degradation rate. The scaffold showed good biocompatibility and high photothermal efficiency, making it suitable for tissue engineering applications.

Summary: The mixed convection of nanofluid within an inclined trapezoidal cavity in the presence of a magnetic field was explored using the lattice Boltzmann method. The study found that increasing the Rayleigh number and decreasing the Richardson number improves heat transfer. Increasing the volume fraction of nanoparticles leads to a higher average Nusselt number. However, increasing the Hartmann number reduces heat transfer. Altering the cavity's slope and the magnetic field's angle also has an effect on the flow and heat transfer. Applying a magnetic field has a more pronounced impact on heat conduction.

Summary: This paper investigates the impact of full dispersion and agglomeration of single-walled carbon nanotubes (SWCNT) in the Aluminum (AL) matrix using the representative volume element (RVE) and finite element method (FEM). The study finds that at higher SWCNT concentrations, local agglomeration occurs within the composites, leading to a decrease in elastic modulus and mechanical strength. Experimental and RVE methods show a consistent agreement. The study also examines AL-SWCNT RVEs under damage condition.
