Research shows that increasing the surface roughness of copper foil helps improve the bonding strength between the current collector and the active material, reduces the contact resistance between them, and consequently enhances the battery's rate discharge performance and cycling stability. In the present work, a copper current collector modification by femtosecond laser treatment forming quasiperiodical nanostructures was proposed. The modified current collectors were examined through scanning electron microscopy (SEM) imaging and roughness measurements and further tested with silicon particles in Li-ion cells through galvanostatic charge/discharge experiments. As a result of the laser process, one can observe increasing contact between the current collector and the active material grains, which creates a buffer zone for the volume expansion of the active material during charging and discharging. The results show increased specific capacities, cyclabilities, and Coulombic efficiencies for modified current collectors compared with standard copper foil. It was demonstrated that implementing laser treatment into standard procedures of electrode manufacturing for lithium-ion batteries can easily improve the electrochemical performance of active materials, especially those that experience large volume changes during cycling.","PeriodicalId":55639,"journal":{"name":"ACS Applied Engineering Materials","volume":"3 9","pages":"3228-3238"},"PeriodicalIF":3.5,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12481476/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, few-layer MoS2 demonstrates superior mechanical strength and carrier mobility compared to monolayer MoS2. This work presents an alternative approach for fabricating high-quality few-layer MoS2 structures. This approach avoids the challenges associated with the direct synthesis of large-area and high-quality few-layer transition-metal dichalcogenides. It also overcomes the limitations of exfoliation methods, which lack precise control over the area, layer number, and positioning. Our methodology involves sequential layer stacking of chemical vapor deposition (CVD)-grown monolayer MoS2 films, followed by nanosheet patterning and high-vacuum annealing to enhance interlayer coupling. Comprehensive characterization using Raman spectroscopy, photoluminescence, atomic force microscopy, and transmission electron microscopy confirms that the resulting structures exhibit optical and physical properties comparable to exfoliated or directly CVD-grown few-layer MoS2. We observe the expected band-gap narrowing and direct-to-indirect-band-gap transition as the number of layers increases. Electrical characterization of FETs fabricated from these structures demonstrates that, at a carrier concentration of 1.5 × 1013 cm–2, the intrinsic mobility increases with layer numbers, from 11.4 cm2/V·s for a monolayer to 26.5 cm2/V·s for trilayers.","PeriodicalId":55639,"journal":{"name":"ACS Applied Engineering Materials","volume":"3 8","pages":"2542–2549"},"PeriodicalIF":3.5,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acsaenm.5c00388","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144885169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is important to understand the relationships between fabrication procedures, nanosheet arrangements, and conductivity. Here, we present a series of improvements on graphene nanosheet transfer including demonstrating a >10x increase in membrane area with comparable sheet resistance (79 Ω/sq) as smaller (11 cm2) samples, controlling the loading of graphene nanosheets, and identifying two flexible polymer membranes viable as transfer media: Celgard 3501 (coated-polypropylene) and microporous ECTFE (ethylene-chlorotrifluoroethylene). These changes produced a range of sheet resistances from 128 to 16 Ω/sq, with total graphene loading producing the most significant decreases in sheet resistance. Additionally, we present a methodology for analyzing the arrangement of the graphene nanosheet layer in the composite membrane by comparing X-ray diffraction (XRD) patterns to those reported in the literature. Even though these grMEs have only a micrometer(s)-scale graphene nanosheet layer, we conclude that their arrangement varied predictably depending on the transfer media and vacuum deposition force applied. Interestingly, different overall amounts of deposited graphene nanosheets generated different XRD correlations with the conductivity, likely the result of the anisotropy between the in-plane and vertical conductivities of stacked nanosheets. Finally, we also report the effect of the membrane polymer in these composite grMEs on the liquid and gas mass transfer under diffusion-dominated conditions to illustrate the potential application of grMEs for an abiotic glucose fuel cell device.","PeriodicalId":55639,"journal":{"name":"ACS Applied Engineering Materials","volume":"3 8","pages":"2335–2345"},"PeriodicalIF":3.5,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144885238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following this successful experiment, two-dimensional (2D) nanomaterials emerged due to their unique properties, such as ultrathin thickness, high conductivity, and lightweight, which are suitable for a wide range of applications such as disease detection devices, cancer therapy, energy storage, lubricants, plant development, and many more. These are unusual materials with large sizes and robust bonding. They typically have just one dimension ranging from 1 to 100 nm, while the remaining two dimensions are enormous (in micrometers). Aside from 2D nanomaterials, other sorts of nanomaterials are developed based on their dimension status, including 0D nanomaterials, 1D nanomaterials, and 3D nanomaterials. The three dimensions of space length (l), width (w), and height (h) may be used to compare the primary differences between all of these dimensions, as can a material. If the nanomaterial’s dimension is set at 100 nm, then a nanomaterial with 0D (quantum dots, etc.) indicates that each of its l, w, and h dimensions is less than 100 nm. One dimension (nanorods and nanotubes) (l, w, and h) is higher than 100 nm in 1D, while the other two dimensions are still less than 100 nm. 2D (nanosheets) indicates that just one of the three dimensions is still smaller than 100 nm, while the other two are larger than 100 nm. Finally, 3D (flower-like structured, cubical form, etc.) denotes that all three dimensions─l, w, and h─are larger than 100.

These contaminants can easily block important sensors for cars, such as cameras and LiDAR. Current anti-icing surfaces and deicing technologies are often not effective during the height of winter. This work describes the fabrication and testing of a protective composite sheet consisting of a slippery organogel matrix and an auxetic structure that both passively and actively sheds ice from the surface to protect these sensors. The organogel matrix excretes a slippery lubricating layer that prevents ice from building on the surface, and a uniaxially stretched auxetic structure creates an area mismatch between the surface of the sheet and the ice. The organogel matrix consists of a silicone elastomer precursor with silicone oil, providing optical transparency. The auxetic structure is 3d printed with a combination of Poly(dimethylsiloxane) (PDMS) with fumed silica added as a rheological modifier to provide additional strength to the structure. Image analysis reveals that the composite sheet has a staggering negative Poisson’s ratio of −0.58. In order to quantify the ice adhesion on the shield, home-built testing equipment is devised to assess the effectiveness of the protective sheets in removing ice built on the surface. A small critical shear stress to remove ice cubes from the sheet (<10 kpa) is achieved in various elastomer and organogel surfaces in static ice adhesion tests. However, active deice testing involving repetitive uniaxial stretching reveals that the auxetic property of the sheet is strictly necessary to remove ice buildup effectively. In conclusion, our composite sheets with a negative Poisson’s ratio with slippery, anti-icing surfaces are effective in removing ice buildup, suggesting their potential usage as a shield for optical sensors in autonomous vehicles and more.","PeriodicalId":55639,"journal":{"name":"ACS Applied Engineering Materials","volume":"3 8","pages":"2614–2623"},"PeriodicalIF":3.5,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144885207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our process employs polyethylene (PE) as the carbon precursor and only involves steps of printing, cross-linking, and pyrolysis. The incomplete coalescence of PE particles during printing results in the formation of a macroporous structure. Moreover, we demonstrate the production of 3D-printed carbon–cobalt nanocomposites through a simple metal immersion step prior to pyrolysis. The electrochemical properties of these structured carbons and carbon–cobalt nanocomposites were investigated, revealing enhanced performance attributed to the synergistic effects of electric double-layer capacitance and pseudocapacitance. Our method is resource-efficient, utilizes inexpensive precursors, and is capable of imparting functional nanoparticles to the carbon matrix.

Precursor exposure time serves as a critical parameter for controlling the deposition behavior and spatial organization of inorganic components within the hybrid fibers. Prolonged exposure time enables deep infiltration and homogeneous dispersion of alumina throughout the polymer fiber matrix, while short exposure time leads to a characteristic surface-rich architecture. These multi-interface hybrid fibers demonstrate exceptional multifunctional properties, including enhanced mechanical strength and thermal stability, making them promising candidates as advanced fillers for dielectric composites. These specially designed fillers were incorporated into PEI/fiber composites, resulting in enhanced dielectric constant, energy storage density, and high breakdown strength (700 kV/mm) while maintaining a low loss tangent and high charge/discharge efficiency when measured using large electrodes while achieving an energy storage density of 8.9 J/cm3 favorable for capacitor applications.
