Summary: The objective of this study is to numerically investigate the thermal performance of cutting fluids dispersed with nanoparticles for effective heat removal during turning operations. The results indicated a drastic drop in the cutting tool temperature with an increase in the volume fraction of dispersed nanoparticles and coolant velocity. It is additionally observed that SWCNT nanocoolants exhibited a superior thermal performance and heat removal rate compared with Al and Al2O3 nanocoolants.

Summary: Plasma-catalytic pyrolysis is a promising technology for upgrading plastic waste and producing hydrogen and high-value carbon materials. This study investigated the role of plasma in the pyrolysis of polypropylene (PP) and found that plasma can further activate and cleave the pyrolysis volatiles, resulting in more active carbon species for the growth of carbon nanotubes (CNTs). Compared to conventional catalytic pyrolysis, plasma addition significantly reduced the formation temperature of CNTs and promoted the conversion of liquid and gaseous products to CNTs and hydrogen. The addition of plasma also improved the graphitization degree of CNTs and reduced their defectivity. The findings highlight the potential of plasma-catalytic pyrolysis for the valorization of plastic waste.

Summary: Uncured solid bisphenol-A epoxy resins containing up to 20 wt% carbon nanotubes were prepared using melt blending in a high shear mixer to produce fine nanocomposite powders. The resulting well-dispersed nanocomposites exhibited improved mechanical properties and through-thickness electrical conductivity with intermediate CNT loadings.

Summary: We developed defect- and oxygen-rich nanocarbons as bifunctional catalysts for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) through a one-pot formation method using plasma discharge in mixed solvents. The presence of embedded and functionalized oxygen with defects in the carbon matrix greatly influenced the catalytic activity of the ORR and OER. Our findings suggest new models for carbon-based bifunctional catalysts and provide a prospective approach for the synthesis of carbon nanomaterials.

Summary: This study investigates the effect of an additional floating electrode on the properties of an atmospheric pressure plasma jet with a cross-field electrode configuration. The experiments show that the presence of an additional floating electrode reduces the power required for the plasma jet to cross the nozzle and increases the jet length. The threshold power and maximum jet length depend on the width of the electrode. The analysis also reveals an improvement in the reactivity of the plasma plume due to the increased optical emission intensity and relative yield of ions in the presence of the additional floating electrode.

Summary: The study focuses on the in-situ assembly of carbon nanotubes (CNTs) using macroscopic dielectrophoresis, overcoming the limitation of small size in traditional manipulation methods. Through optimizing voltage and frequency, ordered CNTs chains can be obtained under the action of alternating current dielectrophoresis, which can restore immediately upon powering up after being damaged. Different conductive patterns on non-woven fabric can be achieved by controlling the position of the electrodes in a wet environment.

Summary: This study measured H2S in a solution containing bovine serum albumin and bovine gamma-globulin using Raman spectroscopy, sulfur K-edge X-ray absorption near-edge spectroscopy, and confocal laser scanning microscopy. The results showed that protein binding does not affect the measurement of H2S by confocal laser scanning microscopy.

Summary: Orthogonal cutting experiments were conducted on carbon nanotube/carbon fiber reinforced polymer composites with varying wt. fractions of multiwalled CNTs (MWCNTs) filled in the epoxy. The study investigated the influence of CNT content, fiber orientation, and depth of cut on the cutting force. Results revealed a different pattern for the cutting force in 135 degrees orientation compared to other orientations. The depth of cut had a more significant effect on the cutting force, particularly when CNTs were included, leading to a shift in the cutting force direction and reduced coefficient of friction along the tool/chip interface.

Summary: In this study, novel DPS/MWCNT composites were successfully synthesized and developed into a nanofluid for enhancing turning performance, which exhibited excellent dispersion, heat transfer, and wetting properties. During turning, the composites and filled DPS in the nanofluid played vital roles in reducing cutting resistance and improving surface quality and tool life, showing significant enhancements in cutting force, temperature, surface roughness, and tool life compared to conventional turning.

Summary: In this study, the formation of carbon nanotube (CNT)-based nanohybrids in aqueous solution is reported, where DNA-wrapped CNTs act as templates for PbS and CdS nanocrystals growth. Multiplexed photoresponsive devices with sensitivity to various illumination wavelengths were fabricated from these nanohybrids. The different photoresponses of the DNA-CNT, CdS-DNA-CNT, and PbS-DNA-CNT devices were attributed to varying operational mechanisms, with PbS-DNA-CNT devices showing the fastest response due to photoinduced charge transfer.

Summary: In this study, superhydrophobic and breathable nanofiber membranes were fabricated using solution blow spinning. The membranes achieved superhydrophobicity through hydrophobic modification treatment. With an average fiber diameter of 0.51 μm and pore size of 13.65 μm, the membranes exhibited good breathability and mechanical properties. The impact of heat treatment on the membranes was also studied.

Summary: Tunable infrared properties are achieved with carbon nanotube networks spray-deposited onto an ionic liquid-infused membrane, allowing for control of emissivity and apparent temperature. These devices utilize intraband transitions in carbon nanotube networks to enable scalable and printed devices, resulting in emissivity modulation from -0.5 to -0.2. The understanding of these devices provides criteria for infrared electrochromic materials, opening the possibility for solution-processable coatings in thermal management applications.
