  Abstract Additive manufacturing of thermosets requires a mechanism for solidifying deposited layers in order to prevent part collapse. To accomplish this, non‐equilibrium plasma is proposed for its ability to target, heat, and cure printed thermosetting resin. Non‐equilibrium plasmas have not been used for the curing of liquid thermoset composites, and so their impact on an uncured resin is unknown. Here this work investigates the mechanism through which dielectric barrier discharge (DBD) heats an epoxy/carbon nanotube (CNT) composite under atmospheric conditions. Plasma applied to resin surfaces is found to cause rapid heating, with heating rate controlled by adjusting the applied power. Heating is localized to within the top 0.5 mm of the sample surface and maximum temperature is found to depend on sample conductivity, indicating the heating reaction occurs through a combination of electron conduction and ion bombardment. Characterization of composites cured using plasma shows oxidation and roughening of the surface. Based on the heating and surface studies, several demonstrative prints are performed using in situ plasma curing. This work shows the potential of DBD plasma to rapidly heat liquid substrates and demonstrates how plasma curing expands the capability of existing direct ink write (DIW) printer technologies.

• Photo-induced degradation of single-use polyethylene terephthalate microplastics under laboratory and outdoor environmental conditions

  Environmental Toxicology and Chemistry · 2025-03-28 · 12 citations

  articleOpen access

  There is a lack of knowledge regarding the mechanisms that induce microplastic fragmentation and degradation within the environment. This research aimed to quantify the combined degradative effects that mechanical abrasion, in conjunction with photo-oxidation and hydrolysis, have on polyethylene terephthalate (PET) microplastics. To accomplish this, common routes of degradation were evaluated. Degradation was assessed using three indices indicative of polymer degradation: the carbonyl index, carbon-to-oxygen index, and hydroxyl index. This study assessed the effects that mechanical abrasion (MA), photo-oxidation, and various simulated environmental conditions: aqueous (Aq), Aq + UV, and UV only within two distinct settings (laboratory vs. outdoor) have on PET microplastic degradation. Photo-oxidation exposure across a 60-day period induced significant degradation on PET microplastics, resulting in a 1%-22% increase in carbonyl groups across all treatments except UV and Aq + UV Chamber (MA). A 6-214% increase in hydroxyl groups across all treatments. A 1-10% decrease in carbon-to-oxygen groups in all treatments except the Chamber Aqueous and Outdoor UV (MA). Mechanical abrasion seemed to accelerate this degradation in combination with both UV and aqueous treatments. Using simulated environmental conditions to induce degradation on PET microplastics in both laboratory and simulated environmentally relevant settings revealed that the combined effects of hydrolysis and photo-oxidation can accelerate the process, especially in conjunction with mechanical abrasion. The novel findings presented here provide insight into the complex relationship between various polymer degradation pathways and the effects that mechanical abrasion can have on them while also providing additional data for an understudied yet prevalent plastic polymer.

• Enhancing coolant performance using carbon nanoparticles as additives

  articleOpen access

  • Adding 0.5 wt.% carbon nanoplatelets boosts EG-based coolant conductivity by 15.7 %. • Thermal diffusivity improves by 45.9 % with 0.5 wt.% carbon nanoplatelets in coolant. • Viscosity drops by 16.6 %, enhancing boundary layer and heat transfer efficiency. • Carbon nanoplatelets show promise for advanced coolants in next-gen automotive use. The mixture of water and ethylene glycol (EG) as conventional coolants has been widely used in automobile radiators for decades. However, these heat-transfer fluids have low thermal conductivity and fail to fulfill the needs of upcoming high-speed and compact vehicles. Nanomaterial additives offer an opportunity to develop new coolants with improved thermal and physical performance. The feasibility of a new class of carbon-based nanomaterial as an additive for coolant is investigated in this work. Experiments were conducted to measure the effect of carbon nanoplatelets on the thermal conductivity, thermal diffusivity, specific heat, and viscosity of ethylene glycol-based coolants. The addition of carbon nanoplatelets into EG:water at a loading of 0.5 wt.% increased thermal conductivity and diffusivity by 15.7 % and 45.9 %, respectively. The addition of 0.5 wt.% of carbon nanoplatelets showed a viscosity drop of 16.6 %. This reduction in viscosity creates a smaller boundary layer, resulting in enhanced heat transfer and better performance. Thus, the improved thermophysical properties offered by this new class of carbon nanoparticles show promise for their use as an additive in coolants.

• The Effect of Biochar on the Dispersion Stability of Graphene Oxide in Alkaline Cement Solution

  ACS Applied Nano Materials · 2025-08-04

  article

  Graphene oxide nanosheets have captured researchers’ interest due to unique morphology and remarkable mechanical properties, positioning them as promising supplementary materials for concrete. Nonetheless, a significant challenge of using graphene oxide in cement-based materials is its poor dispersion in alkaline cement solution. This study investigates the effect of using biochar as a dispersive agent for graphene oxide in both water and cement pore solution. In biochar-free samples, graphene oxide is observed to agglomerate immediately in cement pore solution and form palm tree leaf-like clusters, whereas biochar interacts with reactive cations and trap these cations within its microporous structure. This interaction results in the formation of C–S–H gel-like substances on the surface of biochar-cement and hence the concentration of cations near the functional groups of graphene oxide decreases, leading to significantly improved dispersion. In addition, it has been found that incorporating polycarboxylate ether-based superplasticizer further improves the dispersion stability of graphene oxide in cement pore solution. The results of this study could be the starting point for future researchers to use biochar as a dispersive agent for graphene oxide in cementitious composites. Due to the carbon-negative nature of biochar, cementitious composites containing graphene oxide and biochar will possess not only excellent mechanical and durability properties but also offer significant environmental benefits.

  ). Because these multilayers utilize hydrogen bonding, their properties are highly sensitive to the pH of the assembly and its external environment. Specifically, the reversible deconstruction of these multilayers under basic conditions is experimentally verified. This study shows that hydrogen bonding interactions can be leveraged to form MXene LbL multilayers as gas barriers, electronically conductive coatings, and deconstructable thin films via pH control.
